2 Air Vents Proven Same proven, free-foating a stainess stee mechanism as used in Armstrong steam traps. Leak-tight Positive cosing, free-foating stainess stee ever ensures eak-tight cosing under a conditions. Air Vents Body options Variety of body materias avaiabe: poysufone, cast iron, forged stee and a stainess stee. A materia for every appication. High pressure Armstrong air/gas vents can hande appications to 186 bar. AV-406

3 Seecting The Armstrong Air/Gas Vent With the desired capacity in m³/h known, find the orifice size required from the tabe on this page. Then find the vent or vents with the correct orifice size on pages AV-410 to AV-419 that wi operate at the required pressure with a iquid of the specific gravity being handed. Exampe Find a mode number that wi vent 88,3 m³/h of air (incuding safety factor of 1,5-2,0) from a iquid with a specific gravity of 0,93 at 17 bar. Using the tabe beow, foow the 17 bar ine across to the number 103. Orifice size is 5/32". Now go to pages AV-410 to AV-419 checking the 5/32" orifice ines to ocate a vent for 17 bar or higher with 0,90 gravity iquid. For Venting During Fiing Ony If a vent is required ony for getting rid of air when a system is started up, such as when starting up a deep we pump or fiing an empty pipe, tank or other vesse, abiity of the vent to open at operating pressure can be ignored. In these cases, a mode number with a arge orifice for fast venting may be seected, but the vent wi not open after air is expeed and the system reaches operating pressure. Note: Since specific gravity fas between 0,95 and 0,90, use 0,90 gravity data. The mode 3-AV on page AV-412 is the one to use.

20 1-AVCW See-Thru Air Vent for Ozone Appications For Pressures to 10 bar or Specific Gravity Down to 0,80 What Is Ozone? Ozone is a gas that forms naturay during thunderstorms when ightning converts norma oxygen moecues (O 2 ) into ozone (O 3 ). The fresh, sweet sme in the air after a storm is the sme of ozone. The unstabe ozone moecue reacts rapidy with most substances and is an extremey strong natura oxidant. How Is Commercia Ozone Produced? Ozone can be formed by exposing air to utravioet ight; however, the most common method of generating ozone is by passing air through an eectrica discharge. Because ozone has strong oxidizing properties, its production requires corrosionresistant equipment. Aternate Inet Outet Air Vents How Is Ozone Used in Water Fitration and Purification? Because ozone is such an effective oxidant, it kis viruses, bacteria, mod, midew, fungus and germs. Passing ozone through water achieves high purification rates without any chemica residue. Oxygen is the ony by-product. Typica Customer Appications: Purifying standing ground water in Third Word countries. Conditioning water for poutry and ivestock.

31 Steam Tabes Steam Conservation Guideines What They Are How to Use Them The heat quantities and temperature/pressure reationships referred to in this section are taken from the Properties of Saturated Steam tabe. Definitions of Terms Used Saturated Steam is pure steam at the temperature that corresponds to the boiing temperature of water at the existing pressure. Absoute and Gauge Pressures (Coumn 1). Absoute pressure is pressure in bar (bar(a)) above a perfect vacuum. Gauge pressure is pressure in bar (barg) above atmospheric pressure, which is 1 bar absoute. Gauge pressure (barg) pus 1 equas absoute pressure. Or, absoute pressure in bar minus 1 equas gauge pressure. Pressure/Temperature Reationship (Coumns 1 and 2). For every pressure of saturated steam there is a corresponding temperature. Exampe: The temperature of 9 barg saturated steam is aways 179,9 C. Specific Voume of Steam (Coumn 3). The voume per unit of mass in m 3 /kg. Heat of Saturated Liquid (Coumn 4 and 6). This is the amount of heat required to raise the temperature of one kiogram of water from 0 C to the boiing point at the pressure and temperature shown. It is expressed in kiojoues (kj) or kiocaories (kca). Latent Heat or Heat of Vaporization (Coumn 5 and 7). The amount of heat required to change a kiogram of boiing water to a kiogram of steam. This same amount of heat is reeased when a kiogram of steam is condensed back into a kiogram of water. This heat quantity is different for every pressure/temperature combination, as shown in the steam tabe. How the Tabe is Used In addition to determining pressure/temperature reationships, you can compute the amount of steam that wi be condensed by any heating unit of known kj (kca) output. Conversey, the tabe can be used to determine kj (kca) output if steam condensing rate is known. In the appication portion of this section, there are severa references to the use of the steam tabe.

32 Steam Tabes Fash (Secondary) Steam What is fash steam? When hot condensate or boier water, under pressure, is reeased to a ower pressure, part of it is reevaporated, becoming what is known as fash steam. Why is it important? This fash steam is important because it contains heat units that can be used for economica pant operation and which are otherwise wasted. How is it formed? When water is heated at atmospheric pressure (1,013 bar(a)), its temperature rises unti it reaches 100 C, the highest temperature at which water can exist at this pressure. Additiona heat does not raise the temperature, but converts the water to steam. The heat absorbed by the water in raising its temperature to boiing point is caed sensibe heat or heat of saturated iquid. The heat required to convert water at boiing point to steam at the same temperature is caed atent heat. The unit of heat in common use is the kj. The amount of heat required to raise the temperature of one kg of water by 1 C at atmospheric pressure equas 4,186 kj. If water is heated under pressure, however, the boiing point is higher than 100 C, so the sensibe heat required is greater. The higher the pressure, the higher the boiing temperature and the higher the heat content. If pressure is reduced, a certain amount of sensibe heat is reeased. This excess heat wi be absorbed in the form of atent heat, causing part of the water to fash into steam. Condensate at steam temperature and under 10 bar(a) pressure has a heat content of 762 kj/kg. (See Coumn 4 in Steam Tabe.) If this condensate is discharged to atmospheric pressure (1 bar(a)), its heat content instanty drops to 417 kj/kg. The surpus of 345 kj reevaporates or fashes a portion of the condensate. The percentage that wi fash to steam can be computed using the formua: q % fash steam = 1 - q 2 x 100 r q 1 = Sensibe heat in the condensate at the higher pressure before discharge. q 2 = Sensibe heat in the condensate at the ower pressure to which discharge takes pace. r = Latent heat in the steam at the ower pressure to which the condensate has been discharged. % fash steam = x 100 = 15,3% Chart CG-11-1 shows the amount of secondary steam that wi be formed when discharging condensate to different pressures. Other usefu tabes can be found on page CG-63 (Usefu Engineering Tabes). Steam Conservation Guideines Chart CG Percentage of fash steam formed when discharging condensate to reduced pressure.

33 Steam Basic Concepts Steam Conservation Guideines Steam is an invisibe gas generated by adding heat energy to water in a boier. Enough energy must be added to raise the temperature of the water to the boiing point. Then additiona energy without any further increase in temperature changes the water to steam. Steam is a very efficient and easiy controed heat transfer medium. It is most often used for transporting energy from a centra ocation (the boier) to any number of ocations in the pant where it is used to heat air, water or process appications. As noted, additiona kj are required to make boiing water change to steam. These kj are not ost but stored in the steam ready to be reeased to heat air, cook tomatoes, press pants or dry a ro of paper. The heat required to change boiing water into steam is caed the heat of vaporization or atent heat. The quantity is different for every pressure/temperature combination, as shown in the steam tabes. Steam at Work How the Heat of Steam Is Utiized Heat fows from a higher temperature eve to a ower temperature eve in a process known as heat transfer. Starting in the combustion chamber of the boier, heat fows through the boier tubes to the water. When the higher pressure in the boier pushes steam out, it heats the pipes of the distribution system. Heat fows from the steam through the was of the pipes into the cooer surrounding air. This heat transfer changes some of the steam back into water. That s why distribution ines are usuay insuated to minimize this wastefu and undesirabe heat transfer. When steam reaches the heat exchangers in the system, the story is different. Here the transfer of heat from the steam is desirabe. Heat fows to the air in an air heater, to the water in a water heater or to food in a cooking kette. Nothing shoud interfere with this heat transfer. Condensate Drainage Why It s Necessary Condensate is the by-product of heat transfer in a steam system. It forms in the distribution system due to unavoidabe radiation. It aso forms in heating and process equipment as a resut of desirabe heat transfer from the steam to the substance heated. Once the steam has condensed and given up its vauabe atent heat, the hot condensate must be removed immediatey.

34 Steam Basic Concepts The need to drain the distribution system. Condensate ying in the bottom of steam ines can be the cause of one kind of water hammer. Steam traveing at up to 150 km per hour makes waves as it passes over this condensate (Fig. CG-13-2). If enough condensate forms, high-speed steam pushes it aong, creating a dangerous sug that grows arger and arger as it picks up iquid in front of it. Anything that changes the direction pipe fittings, reguating vaves, tees, ebows, bind fanges can be destroyed. In addition to damage from this battering ram, high-veocity water may erode fittings by chipping away at meta surfaces. The need to drain the heat transfer unit. When steam comes in contact with condensate cooed beow the temperature of steam, it can produce another kind of water hammer known as therma shock. Steam occupies a much greater voume than condensate, and when it coapses suddeny, it can send shock waves throughout the system. This form of water hammer can damage equipment, and it signas that condensate is not being drained from the system. Obviousy, condensate in the heat transfer unit takes up space and reduces the physica size and capacity of the equipment. Removing it quicky keeps the unit fu of steam (Fig. CG-13-3). As steam condenses, it forms a fim of water on the inside of the heat exchanger. Non-condensabe gases do not change into iquid and fow away by gravity. Instead, they accumuate as a thin fim on the surface of the heat exchanger aong with dirt and scae. A are potentia barriers to heat transfer (Fig. CG-13-1) The need to remove air and CO 2. Air is aways present during equipment start-up and in the boier feedwater. Feedwater may aso contain dissoved carbonates, which reease carbon dioxide gas. The steam veocity pushes the gases to the was of the heat exchangers, where they may bock heat transfer. This compounds the condensate drainage probem, because these gases must be removed aong with the condensate.

In the heat exchangers, traps perform the vita function of removing the condensate before it becomes a barrier to heat transfer. Hot condensate is returned through the traps to the boier for reuse.

35 Steam Basic Concepts Steam Conservation Guideines Effect of Air on Steam Temperature When air and other gases enter the steam system, they consume part of the voume that steam woud otherwise occupy. The temperature of the air/steam mixture fas beow that of pure steam. Figure CG-14-1 expains the effect of air in steam ines. Tabe CG-14-1 and Chart CG-14-1 show the various temperature reductions caused by air at various percentages and pressures. Effect of Air on Heat Transfer The norma fow of steam toward the heat exchanger surface carries air and other gases with it. Since they do not condense and drain by gravity, these non-condensabe gases set up a barrier between the steam and the heat exchanger surface. The exceent insuating properties of air reduce heat transfer. In fact, under certain conditions as itte as 1/2 of 1% by voume of air in steam can reduce heat transfer efficiency by 50% (Fig. CG- 15-1). When non-condensabe gases (primariy air) continue to accumuate and are not removed, they may graduay fi the heat exchanger with gases and stop the fow of steam atogether. The unit is then air bound. Corrosion Two primary causes of scae and corrosion are carbon dioxide (CO 2 ) and oxygen (O 2 ). CO 2 enters the system as carbonates dissoved in feedwater and, when mixed with cooed condensate, creates carbonic acid. Extremey corrosive, carbonic acid can eat through piping and heat exchangers (Fig. CG-15-2 ). Oxygen enters the system as gas dissoved in the cod feedwater. It aggravates the action of carbonic acid, speeding corrosion and pitting iron and stee surfaces (Fig. CG- 15-3). Eiminating the Undesirabes To summarize, traps must drain condensate because it can reduce heat transfer and cause water hammer. Traps shoud evacuate air and other non-condensabe gases because they can reduce heat transfer by reducing steam temperature and insuating the system. They can aso foster destructive corrosion. It s essentia to remove condensate, air and CO 2 as quicky and competey as possibe. A steam trap, which is simpy an automatic vave that opens for condensate, air and CO 2 and coses for steam, does this job. For economic reasons, the steam trap shoud do its work for ong periods with minimum attention.

36 Steam Basic Concepts What the Steam Trap Must Do The job of the steam trap is to get condensate, air and CO 2 out of the system as quicky as they accumuate. In addition, for overa efficiency and economy, the trap must aso provide: 1. Minima steam oss. Tabe CG-15-1 shows how costy unattended steam eaks can be. 2. Long ife and dependabe service. Rapid wear of parts quicky brings a trap to the point of undependabiity. An efficient trap saves money by minimizing trap testing, repair, ceaning, downtime and associated osses. 3. Corrosion resistance. Working trap parts shoud be corrosion-resistant in order to combat the damaging effects of acidic or oxygen-aden condensate. 4. Air venting. Air can be present in steam at any time and especiay on start-up. Air must be vented for efficient heat transfer and to prevent system binding. 5. CO 2 venting. Venting CO 2 at steam temperature wi prevent the formation of carbonic acid. Therefore, the steam trap must function at or near steam temperature since CO 2 dissoves in condensate that has cooed beow steam temperature. 6. Operation against back pressure. Pressurized return ines can occur both by design and unintentionay. A steam trap shoud be abe to operate against the actua back pressure in its return system. 7. Freedom from dirt probems. Dirt is an ever-present concern since traps are ocated at ow points in the steam system. Condensate picks up dirt and scae in the piping, and soids may carry over from the boier. Even partices passing through strainer screens are erosive and, therefore, the steam trap must be abe to operate in the presence of dirt. Figure CG Steam condensing in a heat transfer unit moves air to the heat transfer surface, where it coects or pates out to form effective insuation. A trap deivering anything ess than a these desirabe operating/design features wi reduce the efficiency of the system and increase costs. When a trap deivers a these features the system can achieve: 1. Fast heat-up of heat transfer equipment 2. Maximum equipment temperature for enhanced steam heat transfer 3. Maximum equipment capacity 4. Maximum fue economy 5. Reduced abor per unit of output 6. Minimum maintenance and a ong troube-free service ife Sometimes an appication may demand a trap without these design features, but in the vast majority of appications the trap which meets a the requirements wi deiver the best resuts.

37 The Inverted Bucket Steam Trap Steam Conservation Guideines The Armstrong inverted submerged bucket steam trap is a mechanica trap that operates on the difference in density between steam and water. See Fig. CG Steam entering the inverted submerged bucket causes the bucket to foat and cose the discharge vave. Condensate entering the trap changes the bucket to a weight that sinks and opens the trap vave to discharge the condensate. Unike other mechanica traps, the inverted bucket aso vents air and carbon dioxide continuousy at steam temperature. This simpe principe of condensate remova was introduced by Armstrong in Years of improvement in materias and manufacturing have made today s Armstrong inverted bucket traps virtuay unmatched in operating efficiency, dependabiity and ong ife. Long, Energy-Efficient Service Life At the heart of the Armstrong inverted bucket trap is a unique everage system that mutipies the force provided by the bucket to open the vave against pressure. There are no fixed pivots to wear or create friction. It is designed to open the discharge orifice for maximum capacity. Since the bucket is open at the bottom, it is resistant to damage from water hammer. Wearing points are heaviy reinforced for ong ife. An Armstrong inverted bucket trap can continue to conserve energy even in the presence of wear. Gradua wear sighty increases the diameter of the seat and aters the shape and diameter of the ba vave. But as this occurs, the ba merey seats itsef deeper preserving a tight sea. The Armstrong inverted bucket trap owes much of its reiabiity to a design that makes it virtuay free of dirt probems. Note that the vave and seat are at the top of the trap. The arger partices of dirt fa to the bottom, where they are puverized under the up-and-down action of the bucket. Since the vave of an inverted bucket is either cosed or fuy open, there is free passage of dirt partices. In addition, the swift fow of condensate from under the bucket s edge creates a unique sefscrubbing action that sweeps dirt out of the trap. The inverted bucket has ony two moving parts the vave ever assemby and the bucket. That means no fixed points, no compicated inkages nothing to stick, bind or cog. Corrosion-Resistant Parts The vave and seat of Armstrong inverted bucket traps are high chrome stainess stee, ground and apped. A other working parts are wear- and corrosion-resistant stainess stee. Operation Against High Back Pressure High pressure in the discharge ine simpy reduces the differentia across the vave. As back pressure approaches that of inet pressure, discharge becomes continuous just as it does on the very ow pressure differentias. Back pressure has no adverse effect on inverted bucket trap operation other than capacity reduction caused by the ow differentia. There is simpy ess force required by the bucket to pu the vave open, cycing the trap. Figure CG Operation of Inverted Bucket Steam Trap (at pressures cose to maximum) Condensate Steam Air Fashing Condensate Vave Wide Open Vave Cosed Fow Here Picks Up Dirt Reiabe Operation 1. Steam trap is instaed in drain ine between steam-heated unit and condensate return header. On start-up, bucket is down and vave is wide open. As initia food of condensate enters the trap and fows under bottom of bucket, it fis trap body and competey submerges bucket. Condensate then discharges through wide-open vave to return header. 2. Steam aso enters trap under bottom of bucket, where it rises and coects at top, imparting buoyancy. Bucket then rises and ifts vave toward its seat unti vave is snapped tighty shut. Air and carbon dioxide continuay pass through bucket vent and coect at top of trap. Any steam passing through vent is condensed by radiation from trap. CG-16

As the entering condensate starts to fi the bucket, the bucket begins to exert a pu on the ever. As the condensate continues to rise, more force is exerted unti there is enough to open the vave against the differentia pressure. 4. As the vave starts to open, the pressure force across the vave is reduced. The bucket then sinks rapidy and fuy opens the vave. Accumuated air is discharged first, foowed by condensate. The fow under the bottom of the bucket picks up dirt and sweeps it out of the trap. Discharge continues unti more steam foats the bucket, and the cyce repeats. CG-17

39 The Foat and Thermostatic Steam Trap Steam Conservation Guideines The foat and thermostatic trap is a mechanica trap that operates on both density and temperature principes. The foat vave operates on the density principe: a ever connects the ba foat to the vave and seat. Once condensate reaches a certain eve in the trap the foat rises, opening the orifice and draining condensate. A water sea formed by the condensate prevents ive steam oss. Since the discharge vave is under water, it is not capabe of venting air and non-condensabes. When the accumuation of air and non-condensabe gases causes a significant temperature drop, a thermostatic air vent in the top of the trap discharges it. The thermostatic vent opens at a temperature a few degrees beow saturation so it s abe to hande a arge voume of air through an entirey separate orifice but at a sighty reduced temperature. Armstrong F&T traps provide high air-venting capacity, respond immediatey to condensate and are suitabe for both industria and HVAC appications. High Back Pressure Operation Back pressure has no adverse effect on foat and thermostatic trap operation other than capacity reduction due to ow differentia. The trap wi not fai to cose and wi not bow steam due to the high back pressure.

Thus, under conditions of zero pressure, ony the force of gravity is avaiabe to push condensate through a steam trap. Substantia amounts of air may aso be iberated under these conditions of ow steam pressure. The efficient operation of the F&T trap meets a of these speciaized requirements. Figure CG Operation of F&T Steam Trap Condensate Steam Air 1. On start-up, ow system pressure forces air out through the thermostatic air vent. A high condensate oad normay foows air venting and ifts the foat, which opens the main vave. The remaining air continues to discharge through the open vent. 2. When steam reaches the trap, the thermostatic air vent coses in response to higher temperature. Condensate continues to fow through the main vave, which is positioned by the foat to discharge condensate at the same rate that it fows to the trap. 3. As air accumuates in the trap, the temperature drops beow that of saturated steam. The baanced pressure thermostatic air vent opens and discharges air. NOTE: These operationa schematics of the F&T trap do not represent actua trap configuration. CG-18

40 The Controed Disc Steam Trap The controed disc steam trap is a time-deayed device that operates on the veocity principe. It contains ony one moving part, the disc itsef. Because it is very ightweight and compact, the CD trap meets the needs of many appications where space is imited. In addition to the disc trap s simpicity and sma size, it aso offers advantages such as resistance to hydrauic shock, the compete discharge of a condensate when open and intermittent operation for a steady purging action. Figure CG Operation of Controed Disc Traps Unique Heating Chamber The unique heating chamber in Armstrong s controed disc traps surrounds the disc body and contro chamber. A controed beed from the chamber to the trap outet contros the cyce rate. That means that the trap design not ambient conditions contros the cyce rate.

When the pressure above the disc is reduced, the incoming pressure ifts the disc off the seat. If condensate is present, it wi be discharged, and the cyce repeats. The Bimetaic Steam Trap The bimetaic steam trap operates on the temperature principe, using two ayers of bimetaic eements, which have different expansion coefficients. When cod, the bimetaic eements are fat. When the temperature starts to rise, the eements wi expand differenty and wi curve. The stem connected to these eements moves a vave into either an open or cosed position. Figure CG Operation of Bimetaic Steam Traps 1. On start-up, temperature is ow and the bimetaic eements are fat.

41 The Thermostatic Steam Trap Steam Conservation Guideines Armstrong thermostatic steam traps are avaiabe with baanced pressure beows or wafer-type eements and are constructed in a wide variety of materias, incuding stainess stee, carbon stee and bronze. These traps are used on appications with very ight condensate oads. Thermostatic Operation Thermostatic steam traps operate on the difference in temperature between steam and cooed condensate and air. Steam increases the pressure inside the thermostatic eement, causing the trap to cose. As condensate and non-condensabe gases back up in the cooing eg, the temperature begins to drop, and the thermostatic eement contracts and opens the vave. The amount of condensate backed up ahead of the trap depends on the oad conditions, steam pressure and size of the piping. It is important to note that an accumuation of noncondensabe gases can occur behind the condensate backup.

When air coects, the temperature drops and the thermostatic air vent automaticay discharges the air at sighty beow steam temperature throughout the entire operating pressure range. Figure CG Operation of Thermostatic Steam Trap Figure CG Operation of Thermostatic Wafer Steam Condensate Condensate and Air Acoho Vapor Water Acoho Liquid Bukhead Acoho Chamber 1. On start-up, condensate and air are pushed ahead of the steam directy through the trap. The thermostatic beows eement is fuy contracted, and the vave remains wide open unti steam approaches the trap. 2. As the temperature inside the trap increases, it quicky heats the charged beows eement, increasing the vapor pressure inside. When pressure inside the eement becomes baanced with system pressure in the trap body, the spring effect of the beows causes the eement to expand, cosing the vave. When temperature in the trap drops a few degrees beow saturated steam temperature, imbaanced pressure contracts the beows, opening the vave. Baanced Pressure Thermostatic Wafer operation is very simiar to baanced pressure beows described in Fig. CG The wafer is partiay fied with a iquid. As the temperature inside the trap increases, it heats the charged wafer, increasing the vapor pressure inside. When the pressure inside the wafer exceeds the surrounding steam pressure, the wafer membrane is forced down on the vave seat, and the trap is cosed. A temperature drop caused by condensate or non-condensabe gases coos and reduces the pressure inside the wafer, aowing the wafer to uncover the seat. CG-20

42 The Automatic Differentia Condensate Controer Armstrong automatic differentia condensate controers (DC) are designed to function on appications where condensate must be ifted from a drain point or in gravity drainage appications where increased veocity wi aid in drainage. Lifting condensate from the drain point often referred to as syphon drainage reduces the pressure of condensate, causing a portion of it to fash into steam. Since ordinary steam traps are unabe to distinguish fash steam and ive steam, they cose and impede drainage. Increased veocity with gravity drainage wi aid in drawing the condensate and air to the DC. An interna steam by-pass controed by a manua metering vave causes this increased veocity. Therefore, the condensate controer automaticay vents the by-pass or secondary steam. This is then coected for use in other heat exchangers or discharged to the condensate return ine. Capacity considerations for draining equipment vary greaty according to the appication. However, a singe condensate controer provides sufficient capacity for most appications. Condensate Controer Operation Condensate, air and steam (ive and fash) enter through the controer inet. At this point fash steam and air are automaticay separated from the condensate. Then they divert into the integra by-pass at a controed rate, forming secondary steam (See Fig. CG-21-2). The vave is adjustabe so it matches the amount of fash present under fu capacity operation or to meet the veocity requirements of the system. The condensate discharges through a separate orifice controed by the inverted bucket. Because of the dua orifice design, there is a preset controed pressure differentia for the secondary steam system, whie maximum pressure differentia is avaiabe to discharge the condensate.

Users have found that they must generay use a safety factor in sizing steam traps. For exampe, a coi condensing 300 kg/h might require a trap that coud hande up to 900 kg/h for best overa performance. This 3:1 safety factor takes care of varying condensate rates, occasiona drops in pressure differentia and system design factors. Safety factors wi vary from a ow of 1,5:1 to a high of 10:1. The safety factors in this book are based on years of user experience. Configuration affects safety factor. More important than ordinary oad and pressure changes is the design of the steam-heated unit itsef. Refer to Figs. CG-22-3, CG-22-4 and CG-22-5 showing three condensing units each producing 300 kg of condensate per hour, but with safety factors of 2:1, 3:1 and 8:1.

44 Trap Seection Economica steam trap/orifice seection. Whie an adequate safety factor is needed for best performance, too arge a factor causes probems. In addition to higher costs for the trap and its instaation, a needessy oversized trap wears out more quicky. And in the event of a trap faiure, an oversized trap oses more steam, which can cause water hammer and high back pressure in the return system. 3. Pressure differentia. Maximum differentia is the difference between boier or steam main pressure or the downstream pressure of a PRV and return ine pressure. See Fig. CG The trap must be abe to open against this pressure differentia. NOTE: Because of fashing condensate in the return ines, don t assume a decrease in pressure differentia due to static head when eevating. Operating differentia. When the pant is operating at capacity, the steam pressure at the trap inet may be ower than steam main pressure. And the pressure in the condensate return header may go above atmospheric. If the operating differentia is at east 80% of the maximum differentia, it is safe to use maximum differentia in seecting traps. Moduated contro of the steam suppy causes wide changes in pressure differentia. The pressure in the unit drained may fa to atmospheric or even ower (vacuum). This does not prevent condensate drainage if the instaation practices in this handbook are foowed. IMPORTANT: Be sure to read the discussion to the right, which deas with ess common but important reductions in pressure differentia. 4. Maximum aowabe pressure. The trap must be abe to withstand the maximum aowabe pressure of the system or design pressure. It may not have to operate at this pressure, but it must be abe to contain it. As an exampe, the maximum inet pressure is 26 barg and the return ine pressure is 11 barg. This resuts in a differentia pressure of 15 bar; however, the trap must be abe to withstand 26 barg maximum aowabe pressure. See Fig. CG Factors Affecting Pressure Differentia Except for faiures of pressure contro vaves, differentia pressure usuay varies on the ow side of the norma or design vaue. Variations in either the inet or discharge pressure can cause this. Inet pressure can be reduced beow its norma vaue by: 1. A moduating contro vave or temperature reguator. 2. Syphon drainage. Every 1 m of ift between the drainage point and the trap reduces the inet pressure (and the differentia) by 0,1 bar. See Fig. CG Discharge pressure can be increased above its norma vaue by: 1. Pipe friction. 2. Other traps discharging into a return system of imited capacity. 3. Eevating condensate. Every 1 m of ift increases the discharge pressure (and the differentia) by 0,1 bar when the discharge is ony condensate. However, with fash present, the extra back pressure coud be reduced to zero. See Fig. CG-23-3, noting the externa check vave.

45 How to Trap Steam Distribution Systems Steam Conservation Guideines Steam distribution systems ink boiers and the equipment actuay using steam, transporting it to any ocation in the pant where its heat energy is needed. The three primary components of steam distribution systems are boier headers, steam mains and branch ines. Each fufis certain requirements of the system and, together with steam separators and steam traps, contributes to efficient steam use. Drip egs. Common to a steam distribution systems is the need for drip egs at various intervas (Fig. CG-24-1). These are provided to: 1. Let condensate escape by gravity from the fast-moving steam. 2. Store the condensate unti the pressure differentia can discharge it through the steam trap. Figure CG Drip Leg Sizing The propery sized drip eg wi capture condensate. Too sma a drip eg can actuay cause a venturi piccoo effect where pressure drop pus condensate out of the trap. For proper sizing, see Tabe CG-26-2 on page CG-26. Boier Headers A boier header is a speciaized type of steam main that can receive steam from one or more boiers. It is most often a horizonta ine which is fed from the top and in turn feeds the steam mains. It is important to trap the boier header propery to assure that any carryover (boier water and soids) is removed before distribution into the system. Steam traps that serve the header must be capabe of discharging arge sugs of carryover as soon as they are present. Resistance to hydrauic shock is aso a consideration in the seection of traps. Trap seection and safety factor for boier headers (saturated steam ony). A 1,5:1 safety factor is recommended for virtuay a boier header appications. The required trap capacity can be obtained by using the foowing formua: Required Trap Capacity = Safety Factor x Load Connected to Boier(s) x Anticipated Carryover (typicay 10%). EXAMPLE: What size steam trap wi be required on a connected oad of kg/h with an anticipated carryover of 10%? Using the formua: Required Trap Capacity = 1,5 x x 0,10 = kg/h. The abiity to respond immediatey to sugs of condensate, exceent resistance to hydrauic shock, dirt-handing abiity and efficient operation on very ight oads are features that make the inverted bucket the most suitabe steam trap for this appication. Instaation. If steam fow through the header is in one direction ony, a singe steam trap is sufficient at the downstream end. With a midpoint feed to the header (Fig. CG-24-2), or a simiar two-directiona steam fow arrangement, each end of the boier header shoud be trapped.

46 How to Trap Steam Distribution Systems Steam Mains One of the most common uses of steam traps is the trapping of steam mains. These ines need to be kept free of air and condensate in order to keep steam-using equipment operating propery. Inadequate trapping on steam mains often eads to water hammer and sugs of condensate that can damage contro vaves and other equipment. There are two methods used for the warm-up of steam mains supervised and automatic. Supervised warm-up is widey used for initia heating of arge-diameter and/or ong mains. The suggested method is for drip vaves to be opened wide for free bow to the atmosphere before steam is admitted to the main. These drip vaves are not cosed unti a or most of the warmup condensate has been discharged. Then the traps take over the job of removing condensate that may form under operating conditions. Warm-up of principa piping in a power pant wi foow much the same procedure. Automatic warm-up is when the boier is fired, aowing the mains and some or a equipment to come up to pressure and temperature without manua hep or supervision. CAUTION: Regardess of warm-up method, aow sufficient time during the warm-up cyce to minimize therma stress and prevent any damage to the system. Trap seection and safety factor for steam mains (saturated steam ony) Condensate oads on insuated or non-insuated pipe for either supervised or automatic warm-up methods can be cacuated by using the foowing formua: (W p x T 1 ) x c x (t 1 - t 2 ) Q c = r x h x 60 Tabe CG Condensing Rates for Steam Pipes in kg/h/m² Steam Pressure (barg) Pipe with Insuation 1 1 1,5 1,5 2 2,5 3 Pipe without Insuation Tabe CG Pipe Characteristics for Radiation Loss Cacuation Pipe Size Outside Diameter Outside Surface Weight Inches DN mm m²/m kg/m 1/8" 6 10,2 0,03 0,49 1/4" 8 13,5 0,04 0,77 3/8" 10 17,2 0,05 1,02 1/2" 15 21,3 0,07 1,45 3/4" 20 26,9 0,09 1,90 1" 25 33,7 0,11 2,97 1 1/4" 32 42,4 0,13 3,84 1 1/2" 40 48,3 0,15 4,43 2" 50 60,3 0,19 6,17 2 1/2" 65 76,1 0,24 7,90 3" 80 88,9 0,28 10,10 4" ,3 0,36 14,40 5" ,7 0,44 17,80 6" ,1 0,52 21,20 8" ,0 0,69 31,00 10" ,0 0,86 41,60 12" ,0 1,02 55,60 14" ,0 1,12 68,30 16" ,0 1,28 85,90 20" ,0 1,60 135,00 Chart CG Amount of Condensate for 20 m of Pipe Heated From 0 C to Saturated Steam Temperature Steam Conservation Guideines Q c = Amount of condensate in kg/h W p = Weight of pipe in kg/m (see Tabe CG-25-2) T 1 = Tota ength of steam ine in m c = Specific heat of pipe materia in kj/kg/ C (stee pipe = 0,48 kj/kg/ C) t 2 = Fina temperature in C t 1 = Initia temperature in C r = Latent heat in kj/kg (see Steam Tabes, coumn 5 on page CG-10) h = Time in minutes for start-up NOTE: for quick cacuations t 1 can be taken as 0 C and r can be fixed at kj/h.

47 How to Trap Steam Distribution Systems Steam Conservation Guideines For traps instaed between the boier and the end of the steam main, appy a 2:1 safety factor. Appy a 3:1 safety factor for traps instaed at the end of the main or ahead of reducing and shutoff vaves that are cosed part of the time. The inverted bucket trap is recommended because it can hande dirt and sugs of condensate and resists hydrauic shock. In addition, shoud an inverted bucket fai, it usuay does so in the open position. Instaation. Both methods of warm-up use drip egs and traps at a ow spots or natura drainage points such as: Ahead of risers End of mains Ahead of expansion joints or bends Ahead of vaves or reguators Insta drip egs and drain traps even where there are no natura drainage points (See Figs. CG-26-1, CG-26-2 and CG-26-3). These shoud normay be instaed at intervas of about 50 m and never onger than 75 m. On a supervised warm-up, make drip eg ength at east 1,5 times the diameter of the main, but never ess than 250 mm. Make drip egs on automatic warm-ups a minimum of 700 mm in ength. For both methods, it is a good practice to use a drip eg the same diameter as the main up to 100 mm pipe size and at east 1/2 of the diameter of the main above that, but never ess than 100 mm.

48 How to Trap Steam Distribution Systems Branch Lines Branch ines are take-offs from the steam mains suppying specific pieces of steam-using equipment. The entire system must be designed and hooked up to prevent accumuation of condensate at any point. Trap seection and safety factor for branch ines. The formua for computing condensate oad is the same as that used for steam mains. Branch ines aso have a recommended safety factor of 3:1. Instaation. Recommended piping from the main to the contro is shown in Fig. CG-27-1 for runouts under 3 m and Fig. CG-27-2 for runouts over 3 m. See Fig. CG-27-3 for piping when contro vave must be beow the main. Insta a fu pipe-size strainer ahead of each contro vave as we as ahead of the PRV, if used. Provide bowdown vaves, preferaby with IB traps. A few days after starting the system, examine the strainer screens to see if ceaning is necessary. Separators Steam separators are designed to remove any condensate that forms within steam distribution systems. They are most often used ahead of equipment where especiay dry steam is essentia. They are aso common on secondary steam ines, which by their very nature have a arge percentage of entrained condensate. Branch Line 3 m or Less Pitch 50 mm per meter Important factors in trap seection for separators are the abiity to hande sugs of condensate, provide good resistance to hydrauic shock and operate on ight oads. Trap seection and safety factors for separators. Appy a 3:1 safety factor in a cases, even though different types of traps are recommended, depending on condensate and pressure eves. Use the foowing formua to obtain the required trap capacity: Required trap capacity in kg/h = safety factor x steam fow rate in kg/h x anticipated percent of condensate (typicay 10%). EXAMPLE: What size steam trap wi be required on a fow rate of 500 kg/h? Using the formua: Required trap capacity = 3 x 500 x 0,10 = 150 kg/h. The inverted bucket trap with arge vent is recommended for separators. When dirt and hydrauic shock are not significant probems, an F&T type trap is an acceptabe aternative. An automatic differentia condensate controer may be preferred in many cases. It combines the best features of both of the above and is recommended for arge condensate oads that exceed the separating capabiity of the separator. Instaation Connect traps to the separator drain ine 250 mm to 300 mm beow the separator with the drain pipe running the fu size of the drain connection down to the trap take-off (Fig. CG-27-4). The drain pipe and dirt pocket shoud be the same size as the drain connection.

49 How to Trap Superheated Steam Lines Steam Conservation Guideines At first gance, this may seem confusing due to the idea that superheated steam produces no condensate; therefore, the steam ines carrying superheated steam shoud not have any condensate in them. This is true once the system is up to temperature and pressure, but condensate remova is necessary up to this point. This section wi expain what superheated steam is and the appications for its use. The specific heat of any substance (using kj standards) is the quantity of heat required to raise the temperature of 1 kg by 1 C. With this definition, the specific heat of water is 4,186 kj, and the specific heat of superheated steam varies according to temperature and pressure. Specific heat decreases as the temperature rises but increases as the pressure goes up. Superheated steam is customariy made by the addition of an extra set of cois inside the boier or in the exhaust area of the boier so as to use the waste heat from the boier. Or, by the addition of a superheat chamber somewhere after the boier, attached to the steam main. A schematic diagram of a steam generator with a superheated section of coi is shown beow. Properties of Superheated Steam Superheated steam has severa properties that make it unsuitabe as a heat energy exchange medium yet idea for work and mass transfer. Unike saturated steam, the pressure and temperature of superheated steam are independent. As superheat is formed at the same pressure as the saturated steam, the temperature and voume increase. In high heat reease boiers with reativey sma drums, separation of steam from water is extremey difficut. The combination of the sma voume of water in the drums and rapid oad swings produces severe shrink and swe conditions in the drum, which promotes water carryover. Figure CG Steam Generator This water can be removed with separators and traps in the steam outets, but they are not 100% efficient. In appications where dry steam is a necessity, additiona superheating cois are paced in the boier furnace as convection passes. More heat is added to the steam to vaporize the water carryover, which adds a sma amount of superheat to guarantee absoutey dry steam. Because superheated steam can give up so itte heat before it converts back to saturated steam, it is not a good heat-transfer medium. Some processes, such as power pants, require a dry heat in order to do work. Whatever the type of power unit, superheat heps reduce the amount of condensation when starting from cod. Superheat aso increases the power output by deaying condensation during the expansion stages in the equipment. Having drier steam at the exhaust end wi increase the ife of turbine bades. Superheated steam can ose heat without condensing whereas saturated steam cannot. Therefore, superheated steam can be transported through very ong steam ines without osing sufficient heat to condense. This permits the deivery of dry steam throughout the entire steam system. Why Trap Superheated Systems? The primary reason for traps on superheat systems is the startup oad. It can be heavy because of the arge size of the mains. On start-up, manua vaves wi most ikey be used since time is avaiabe to open and to cose the vaves. This is known as supervised start-up. A second reason for steam traps is to hande emergencies such as superheater oss or by-pass, which might require operation on saturated steam. In these unschedued events, there is no time avaiabe for manuay opening vaves; therefore, steam traps are a necessity. These are the situations for which proper trap sizing is a must. Condensate must be removed as it forms in any steam system to keep efficiency high and to minimize damaging water hammer and erosion.

50 How to Trap Superheated Steam Lines Sizing Superheat Loads to Traps The condensate oad to a trap used on superheat wi vary widey from severe start-up oads to virtuay no oad during operation. Consequenty, this is a demanding appication for any steam trap. During start-up, very arge ines are being fied with steam from cod conditions. At this time, ony saturated steam at ow pressure is in the ines unti the ine temperature can be increased. This is done sowy over a ong period so the ines are not stressed. Large condensate fow combined with ow pressure is the start-up condition that requires the use of arge capacity traps. These oversized traps are then required to operate at very high pressures with very ow capacity requirements during norma superheat operation. Typica start-up oads can be roughy cacuated as foows: Using: 0,48 W p (t 2 - t 1 ) C = H Where: C = Amount of condensate in kg W p = Tota weight of pipe (from Tabe CG-25-2 on page CG-25) H = Tota heat of X pressure minus Sensibe heat of Y Pressure (Latent heat of steam. For ong warm-up times, use the tota heat of saturated steam at the superheat steam suppy pressure (X) minus the sensibe heat of saturated steam at the average pressure (Y) during the warm-up time invoved.) 0,48 = Specific heat of stee pipe in kj/kg/ C EXAMPLE: Assuming a 50 C/h heat-up 14'' diameter Schedue 80 ine Suppy superheated steam at 83 bar, 577 C Ambient temperature is 21 C 60 m of run between traps For the first two hours: W = 60 m x 68,3 kg/m = kg t 2 - t 1 = = 100 C H = kj/kg (83 barg) kj/kg (0,35 barg) = kj C = 0,48 kj/kg/ C x kg x 100 C kj/kg = 85,6 kg For the second two hours: The ony thing that changes is the sensibe heat (775 kj/kg) of the saturated steam at average pressure during the time invoved. 0,48 kj/kg/ C x kg x 100 C C = = 99,4 kg kj/kg Tabe CG Time Period Tabe Time Period Average Pressure in barg Temperature at End of Time Period in C 14" Line Condensation Rate in kg/h 1 st 2 hours 0, ,9 2 nd 2 hours 9, ,7 3 rd 2 hours ,5 4 th 2 hours ,3 5 th 2 hours ,2 NOTE: For the average pressure of 83 barg, assume H to be the atent heat of 83 barg steam pus superheat at temperature at the end of the period. To ensure the condensate is removed efficienty, proper drip eg sizing and piping recommendations shoud aso be foowed when instaing traps on superheat systems. The Tabe CG-26-2 on page CG-26 ists the proper drip eg size for given pipe sizes. The question arises whether insuation shoud be used on the drip eg, piping eading to the trap, and the trap. The answer is no; uness it is mandatory for safety reasons, this section of the steam system shoud not be insuated. This ensures that some condensate is continuousy being formed ahead of the trap and going to it, thus proonging the trap s ife. Types of Superheat Traps Bimetaic A bimetaic trap is set to not open unti condensate has cooed to a temperature beow saturation. For the existing pressure, it wi remain cosed whenever steam of any temperature is in the trap. As the steam temperature rises, the pu of the bimetaic eement becomes greater, providing a greater seaing force on the vave. Superheated steam tends to sea the vave better. The bimetaic trap aso has the abiity to hande arge start-up oads. For these reasons, this trap is a good choice for superheat. During superheat operation, the condensate in the trap must coo to a temperature beow the saturation temperature before the trap can open. Condensate may back up into the ine and cause damage to the ines, vaves and equipment if drip eg size and ength before the trap are insufficient. Inverted Bucket A water sea prevents steam from getting to the vave, promoting no ive steam oss and ong ife. The vave at the top makes it impervious to dirt and permits remova of air. Large start-up oads can be handed, and the trap can sti accommodate sma running oads. There are probems associated with its appication on superheat, mosty associated with the necessity of maintaining its water sea or prime. Proper piping is necessary to maintain a prime in the IB. For proper inverted bucket piping on superheat, refer to Figure CG-26-3 on page CG-26. When sizing a superheat trap, size for start-up oad with no safety factor. Body materias shoud be seected on the basis of maximum pressure and temperature, incuding superheat. Steam Conservation Guideines CG-29

51 How to Trap Steam Tracer Lines Steam Conservation Guideines Steam tracer ines are designed to maintain the fuid in a primary pipe at a certain uniform temperature. In most cases, these tracer ines are used outdoors, which makes ambient weather conditions a critica consideration. The primary purpose of steam traps on tracer ines is to retain the steam unti its atent heat is fuy utiized and then discharge the condensate and non-condensabe gases. As is true with any piece of heat transfer equipment, each tracer ine shoud have its own trap. Even though mutipe tracer ines may be instaed on the same primary fuid ine, unit trapping is required to prevent short circuiting. See page CG-22. In seecting and sizing steam traps, it s important to consider their compatibiity with the objectives of the system, as traps must: 1. Conserve energy by operating reiaby over a ong period of time. 2. Provide abrupt periodic discharge in order to purge the condensate and air from the ine. 3. Operate under ight oad conditions. 4. Resist damage from freezing if the steam is shut off. The cost of steam makes wastefu tracer ines an exorbitant overhead no industry can afford. Trap Seection for Steam Tracer Lines. The condensate oad to be handed on a steam tracer ine can be determined from the heat oss from the product pipe by using this formua: Q c = k x L x S r Where: Q c = Condensate oad, kg/h k = Heat osses from insuated pipe in kg/h/m² (see Tabe CG-25-1, page CG-25) L = Length of main pipe in meters S = Outside surface of pipe in m²/m (see Tabe CG-25-2, page CG-25) r = Latent heat in kj/kg (see Steam Tabes, coumn 5 on page CG-10) Figure CG Typica Tracer Instaation Vacuum Breaker Tabe CG Recommendation Chart (See Page CG-9 for Feature Code References.)

52 How to Trap Steam Tracer Lines EXAMPLE: Three tracer ines at 11 barg steam pressure are used on a 100 mm diameter, 30 m ong insuated pipe to maintain a temperature of 100 C with an outdoor design temperature of -25 C. For such conditions, the recommended pipe insuation thickness is 100 mm (see Tabes CG-31-2 and CG-31-3). What is the condensate oad? Using the formua: 45,7 W/m x 3,6 kj/h/w x 30 m Q c = = 2,5 kg/h kj/kg Now divide by three in order to get the oad per tracer ine 0,84 kg/h. On most tracer ine appications, the fow to the steam trap is surprisingy ow; therefore, the smaest trap is normay adequate. Based on its abiity to conserve energy by operating reiaby over a ong period of time, hande ight oads, resist freezing and purge the system, an inverted bucket trap is recommended for tracer ine service. Safety factor. Use a 2:1 safety factor whether exposure to ambient weather conditions is invoved or not. Do not oversize steam traps or tracer ines. Instaation Insta distribution or suppy ines at a height above the product ines requiring steam tracing. For the efficient drainage of condensate and purging of non-condensabes, pitch tracer ines for gravity drainage and trap a ow spots. This wi aso hep avoid tracer ine freezing. (See Figs.

53 How to Trap Space Heating Equipment Steam Conservation Guideines Space heating equipment such as unit heaters, air handing units, finned radiation and pipe cois is found in virtuay a industries. This type of equipment is quite basic and shoud require very itte routine maintenance. Consequenty, the steam traps are usuay negected for ong periods of time. One of the probems resuting from such negect is residua condensate in the heating coi, which can cause damage due to freezing, corrosion and water hammer. Trap Seection and Safety Factors Different appication requirements invoving constant or variabe steam pressure determine which type and size of trap shoud be used. There are two standard methods for sizing traps for cois. 1. Constant Steam Pressure. INVERTED BUCKET TRAPS AND F&T TRAPS Use a 3:1 safety factor at operating pressure differentias. 2. Moduating Steam Pressure. F&T TRAPS AND INVERTED BUCKET TRAPS WITH THERMIC BUCKETS n 0-1 barg steam 2:1 safety factor at 0,1 bar pressure differentia n n 1-2 barg steam 2:1 at 0,2 bar pressure differentia Above 2 barg steam 3:1 at 1/2 of maximum pressure differentia across the trap. INVERTED BUCKET TRAPS WITHOUT THERMIC BUCKETS Above 2 barg steam pressure ony 3:1 at 1/2 of maximum pressure differentia across the trap. Trap Seection for Unit Heaters and Air Handing Units You may use three methods to compute the amount of condensate to be handed. Known operating conditions wi determine which method to use. 1. kj method. The standard rating for unit heaters and other air cois is kj output with 0,15 barg steam pressure in the heater and entering air temperature of 15 C. To convert from standard to actua rating, use the conversion factors in Tabe CG-34-1 (page CG-34). Once the actua operating conditions are known, mutipy the condensate oad by the proper safety factor. 2. m³/min and air temperature rise method. If you know ony m³/min capacity of fan and air temperature rise, find the actua kj output by using this simpe formua: kj/h = m³/min x 75 x temperature rise in C. EXAMPLE: What size trap wi drain a 100 m³/min heater that produces an 30 C temperature rise? Steam pressure is constant at 5 barg. Using the formua: 100 x 75 x 30 = kj/h. Now divide kj/h by kj/kg (from the Steam Tabes) to obtain 108 kg/h of condensate and then mutipy by the recommended safety factor 3. The appication needs a trap with a 324 kg/h capacity. Derive the 75 factor in the above formua as foows: 1 m³/min x 60 = 60 m³/h 60 m³/h x 1,25 kg/m³ (the specific gravity of air at 5 C) = 75 kg/h of air 75 kg/h x 1 kj/kg/ C (specific heat of air) = 75 kj/h/ C. 3. Condensate method. Once you determine kj output: a. Divide kj output by atent heat of steam at steam pressure used. See Coumn 2 of Tabe CG-34-1 or the Steam Tabes (page CG-10). This wi give the actua weight of steam condensed. For a cose approximation, a rue of thumb coud be appied in which the kj output is simpy divided by b. Mutipy the actua weight of steam condensing by the safety factor to get the continuous trap discharge capacity required.

54 How to Trap Space Heating Equipment Trap Seection for Pipe Cois and Finned Radiation Pipe cois. Insofar as possibe, trap each pipe individuay to avoid short circuiting. Singe pipe cois. To size traps for singe pipes or individuay trapped pipes, find the condensing rate per meter of pipe in Tabe CG-34-2 (page CG-34). Mutipy the condensing rate per meter by the ength in meters to get the norma condensate oad. For quick heating, appy a trap seection safety factor of 3:1 and use an inverted bucket trap with a thermic vent bucket. Where quick heating is not required, use a trap seection safety factor of 2:1 and seect a standard inverted bucket trap. Mutipe pipe cois. To size traps to drain cois consisting of mutipe pipes, proceed as foows: 1. Mutipy the ength in meters of pipe in the coi by the condensing rate given in Tabe CG This gives the norma condensate oad in kg/h. 2. From Chart CG-32-1 (page CG-32), find the mutipier for your service conditions. 3. Mutipy norma condensate oad by mutipier to get trap required continuous discharge capacity. Note that the safety factor is incuded in the mutipier. Finned radiation. When kj output is not known, condensing rates can be computed from Tabes CG-34-3 and CG-34-4 (page CG-34) with sufficient accuracy for trap seection purposes. To enter Tabe CG-34-3, observe size of pipe, size of fins, number of fins and materia. Determine condensing rate per meter under standard conditions from Tabe CG Convert to actua conditions with Tabe CG Figure CG Trapping and Venting Air Heat Coi Safety factor recommendations are to: 1. Overcome the short circuiting hazard created by the mutipe tubes of the heater. 2. Ensure adequate trap capacity under severe operating conditions. In extremey cod weather the entering air temperature is ikey to be ower than cacuated, and the increased demand for steam in a parts of the pant may resut in ower steam pressures and higher return ine pressures a of which cut trap capacity. 3. Ensure the remova of air and other non-condensabes. WARNING: For ow-pressure heating, use a safety factor at the actua pressure differentia, not necessariy the steam suppy pressure, remembering that the trap must aso be abe to function at the maximum pressure differentia it wi experience.

56 How To Trap Process Air Heaters Process air heaters are used for drying paper, umber, mik, starch and other products as we as preheating combustion air for boiers. Common exampes of this type of equipment are process dryers, tunne dryers, and combustion air preheaters. Compared with air heaters for space heating, process air heaters operate at very high temperature, 260 C not being uncommon. These extremey high-temperature appications require high pressure (and occasionay superheated) steam. Trap Seection and Safety Factor Determine the condensate oad for process air heaters with the foowing formua: Q c = V x c x r x 60 min/h x Δt r Where: Q c = Condensate oad in kg/h V = Cubic meters of air per minute c = Specific heat of air in kj/kg/ C (from Tabe CG-62-2, page CG-62) r = Density of air 1,2 kg/m³ at 15 C (air suppy temperature) Δt = Temperature rise in C r = Latent heat of steam in kj/kg (see Steam Tabes, coumn 5 on page CG-10) EXAMPLE: What woud be the condensate oad on a tunne dryer coi handing 60 m³/min of air and requiring a 35 C temperature rise? The steam pressure is 5 barg. Using the formua: 60 x 1 x 1,2 x 60 x 35 Q = Q = 72,5 kg/h Safety Factors For constant steam pressure, use a safety factor of 2:1 at operating pressure differentia. For moduating steam pressure, use a safety factor of 3:1 at 1/2 of maximum pressure differentia across the trap. Instaation Give piping for an entire piece of process air heating equipment incuding a steam trap connections adequate aowance for expansion due to the wide temperature variations. Mount traps mm beow the cois with a dirt pocket of at east 150 mm. On both constant and moduated pressure heaters, insta a vacuum breaker between the coi and the steam trap. Insta an air vent on each coi to remove air and other noncondensabes that can cause rapid corrosion. See Figure CG Consider a safety drain if condensate is eevated after the trap or if back pressure is present. See page CG-56 for piping diagram and expanation. Steam Conservation Guideines Mutipying by a safety factor of 2 which is recommended for a constant pressure process air heaters indicates that a trap with a capacity of 145 kg/h wi be required. This is based on one coi. For higher air temperature rises, additiona cois in series may be required.

57 How to Trap She & Tube Heat Exchangers & Submerged Cois Steam Conservation Guideines Submerged cois are heat transfer eements that are immersed in the iquid to be heated, evaporated or concentrated. This type of coi is found in virtuay every pant or institution that uses steam. Common exampes are water heaters, reboiers, suction heaters, evaporators and vaporizers. These are used in heating water for process or domestic use, vaporizing industria gases such as propane and oxygen, concentrating in-process fuids such as sugar, back iquor and petroeum, and heating fue oi for easy transfer and atomization. Different appication requirements invoving constant or variabe steam pressure determine which type of trap shoud be used. Trap seection factors incude the abiity to hande air at ow differentia pressures, energy conservation and the remova of dirt and sugs of condensate. Three standard methods of sizing hep determine the proper type and size traps for cois. Safety Factor 1. Constant Steam Pressure. INVERTED BUCKET TRAPS OR F&T TRAPS use a 2:1 safety factor at operating pressure differentias. 2. Moduating Steam Pressure. F&T TRAPS OR INVERTED BUCKET TRAPS barg steam 2:1 at 0,1 bar pressure differentia barg steam 2:1 at 0,2 bar pressure differentia. 3. Above 2 barg steam 3:1 at 1/2 of maximum pressure differentia across the trap. 3. Constant or Moduating Steam Pressure with Syphon Drainage. An automatic differentia condensate controer with a safety factor of 3:1 shoud be used. An aternate is an IBLV with a 5:1 safety factor. Appy the safety factor at fu differentia on constant steam pressure. Appy the safety factor at 1/2 maximum differentia for moduating steam pressure. She and Tube Heat Exchangers One type of submerged coi is the she and tube heat exchanger (Fig. CG-36-1). In these exchangers, numerous tubes are instaed in a housing or she with confined free area. This ensures positive contact with the tubes by any fuid fowing in the she. Athough the term submerged coi impies that steam is in the tubes and the tubes are submerged in the iquid being heated, the reverse can aso be true, where steam is in the she and a iquid is in the tubes. Trap Seection for She and Tube Heat Exchangers To determine the condensate oad on she and tube heaters, use the foowing formua when actua rating is known.* (If heating coi dimensions aone are known, use formua shown for embossed cois. Be sure to seect appicabe k factor): Q c = m x Δt x c x 60 x s.g. r Where: Q c = Condensate oad in kg/h m = Liquid fow in /min Δt = Temperature rise in C c = Specific heat of iquid in kj/kg/ C (Tabe CG-62-1, page CG-62) 60 = 60 min/h s.g.= Specific gravity of iquid (Tabe CG-62-1, page CG-62) r = Latent heat of steam in kj/kg (see Steam Tabes, coumn 5 on page CG-10) EXAMPLE: Assume a water fow rate of 30 /min with an entering temperature of 20 C and a eaving temperature of 120 C. Steam pressure is 1 barg. Determine the condensate oad. Using the formua: 30 /min x 100 C x 4,18 kj/kg/ C x 60 x 1 Q c = = 333 kg/h kj/kg * Size steam traps for reboiers, vaporizers and evaporators (processes that create vapor) using the formua for EMBOSSED COILS on page CG-37.

58 How to Trap She & Tube Heat Exchangers & Submerged Cois Rue of Thumb for Computing Condensing Rate for Water Heaters: Raising the temperature of 500 iters of water by 1 C wi condense one kiogram of steam. Embossed Cois Very often open tanks of water or chemicas are heated by means of embossed cois (Fig. CG-37-1). Upsetting grooves in the sheet meta of the two haves produce the spaces for the steam. When weded together, the haves form the passages for steam entry, heat transfer and condensate evacuation. Trap Seection for Embossed Cois When two fowing iquids are separated and have two different temperatures, one of them increasing whie the other is decreasing, there is a ogarithmic temperature difference between the two iquids as between steam and a iquid (or the inet and outet of a heat exchanger) in t m. Δt 1 Δt 2 Δt m = where Δt L n x 1 Δt 2 Δt 1 = the greatest temperature difference Δt 2 = the east temperature difference The L n temperature difference can be determined with sighty ess accuracy by using Chart CG-41-1 (page CG-41).

59 How to Trap She & Tube Heat Exchangers & Submerged Cois Steam Conservation Guideines Pipe Cois Pipe cois are heat transfer tubes immersed in vesses that are arge in voume compared to the cois themseves (Fig. CG-37-2, page CG-37). This is their primary difference when compared to she and tube heat exchangers. Like embossed cois, they may be drained by gravity or syphon drained, depending on the conditions prevaiing at the instaation site. Unike embossed cois, most pipe cois are instaed in cosed vesses. Trap Seection for Pipe Cois Determine the condensate oad for pipe cois by appying one of the formuas, depending on known data. If capacity is known, use the formua under she and tube heat exchangers. When physica dimensions of coi are known, use the formua under embossed cois. Instaation When gravity drainage is utiized on she and tube heat exchangers, embossed cois and pipe cois, ocate the steam trap beow the heating coi. Under moduating pressure, use a vacuum breaker. This can be integra in F&T traps or mounted off the inet piping on an inverted bucket trap. Pace an ampe drip eg ahead of the trap to act as a reservoir. This ensures coi drainage when there is a maximum condensate oad and a minimum steam pressure differentia. Avoid ifting condensate from a she and tube heat exchanger, embossed coi or pipe coi under moduated contro. However, if it must be done, the foowing is suggested: 1. Do not attempt to eevate condensate more than 0,2 bar of norma pressure differentia, either before or after the trap. 2. If condensate ift takes pace after the steam trap, insta a ow-pressure safety drain (See page CG-56). 3. If condensate ift takes pace ahead of the steam trap (syphon ift), insta an automatic differentia condensate controer to efficienty vent a fash steam.

60 How to Trap Evaporators Evaporators reduce the water content from a product through the use of heat. They are very common to many industries, especiay paper, food, texties, chemica and stee. An evaporator is a she and tube heat exchanger where the steam is normay in the she and the product is in the tubes and in motion. Depending upon the type of product and the desired resuts, more than one stage or effect of evaporation may be required. The tripe effect is the most common, athough as many as five or six can be found on some appications. Singe Effect Whie the product is being forced through the tubes of the evaporator, heat is added to remove a specific amount of moisture. After this is competed, both the product vapor and the concentrated product are forced into the separating chamber where the vapor is drawn off and may be used esewhere. The concentrate is then pumped off to another part of the process (Fig. CG-31-1). Mutipe Effect In using the mutipe effect method, there is a conservation of heat as steam from the boier is used in the first effect, and then vapor generated from the product is used as the heat source in the second effect. The vapor generated here is then used as the heat source in the third effect and finay heats water for some other process or preheats the incoming feed (Fig. CG-39-2). There are many variabes in the design of evaporators due to their wide appication to many different products. The steam capabiities for evaporators can vary from approximatey 500 kg/h to kg/h, whie steam pressures may vary from a high of 10 barg in the first effect to a ow of 60 cm vacuum in the ast effect. Because evaporators are normay run continuousy, there is a uniform oad of condensate to be handed. It s important to remember that traps must be seected for the actua pressure differentia for each effect. The three major considerations when trapping evaporators are: 1. Large condensate oads. 2. Low pressure differentias in some effects. 3. The evacuation of air and contaminants. Safety Factor n When oad is fairy constant and uniform, a 2:1 safety factor shoud be adequate when appied to an actua condensing oad in excess of kg/h. n Beow kg/h, use a 3:1 safety factor. For singe and mutipe effect evaporators, automatic differentia condensate controers are recommended. In addition to offering continuous operation, DC traps vent air and CO 2 at steam temperature, hande fash steam and respond immediatey to sugs of condensate.

61 How to Trap Evaporators Steam Conservation Guideines Instaation Because an evaporator is basicay a she and tube heat exchanger with the steam in the she, there shoud be separate steam air vents on the heat exchanger. Pace these vents at any area where there is a tendency for air to accumuate, such as in the quiet zone of the she. Insta a separate trap on each effect. Whie the condensate from the first effect may be returned to the boier, condensate from each successive effect may not be returned to the boier due to contamination from the product. Trap Seection for Evaporators When cacuating the condensate oad for evaporators, take care in seecting the k vaue (kj/h.m². C). As a genera rue, the foowing k vaues can be used: n for natura circuation evaporators with ow pressure steam (up to 2 barg) n on natura circuation with high pressure (up to 3 barg) n with forced circuation evaporators Use the foowing formua to compute heat transfer for constant steam pressure continuous fow heat exchangers. H = A x k x Δt m Where: H = Tota heat transferred in kj per hour A = Area of outside surface of coi in m² k = Overa rate of heat transfer in kj/h.m². C (See Tabes CG-37-1 and CG-37-2) Δt m = Logarithmic mean temperature difference between steam and iquid (as between inet and outet of a heat exchanger) in C Δt m = Δt 1 - Δt 2 L n x Δt 1 Δt 2 Where: Δt 1 = Greatest temperature difference Δt 2 = Least temperature difference Logarithmic mean temperature difference can be estimated by using the nomograph, Chart CG EXAMPLE: A = Heat transfer tubes: eight 3/4" OD tubes 3,6 m ong 8 x 3,6 = 1,7 m² 16,7 (from Tabe CG-22) k = kj/h.m². C Conditions: Water in: 4,5 C Water out: 65,5 C 8,5 barg steam or 178,3 C steam temperature: Δt 1 = 178,3 C - 4,5 C = 173,8 C Δt 2 = 178,3 C - 65,5 C = 112,8 C Dividing by 4 to get within range of Chart CG-41-1, we have: Δt 1 = 43,5 C Δt 2 = 28,2 C Mean difference from chart is 35 C. Mutipying by 4, the mean temperature difference for the origina vaue is 140 C. Substituting in the equation: H = 1,7m² x kj/h.m². C x 140 C = kj/h Latent heat of steam at 8,5 barg = kj/kg kj/h = kg/h kj/kg To determine trap capacity required, mutipy the condensing rate by the recommended safety factor. CG-40

63 How to Trap Jacketed Kettes Steam Conservation Guideines Steam jacketed kettes are essentiay steam jacketed cookers or concentrators. They are found in a parts of the word and in amost every kind of appication: meat packing, paper and sugar making, rendering, fruit and vegetabe processing and food preparation to name a few. There are basicay two types of steam jacketed kettes fixed gravity drain and titing syphon drain. Each type requires a speciaized method for trapping steam, athough the major probems invoved are common to both. The most significant probem encountered is air trapped within the steam jacket, which adversey affects the temperature. Jacketed kettes usuay perform batch operations, and maintaining a uniform or cooking temperature is critica. With an excessive amount of air, wide variations in temperature occur and may resut in burnt product and/or sow production. To be more specific, under certain conditions as itte as 1/2 of 1% by voume of air in steam can form an insuating fim on the heat transfer surface and reduce efficiency as much as 50%. See pages CG-14 and CG-15. A second basic concern in the use of steam jacketed kettes is the need for a steady, thorough remova of condensate. Accumuation of condensate in the jacket eads to unreiabe temperature contro, reduces the output of the kette and causes water hammer. Trap Seection for Jacketed Kettes The required trap capacity for kettes can be determined through use of the foowing formua: Q c = k x A x Δt r Where: Q c = Condensate oads in kg/h k = Heat transfer rate in kj/h.m². C A = Area in m² Δt = Temperature rise of the iquid C r = Latent heat of the steam in kj/kg EXAMPLE: What woud be the recommended trap capacity for a gravity drained kette with an inside diameter of 800 mm and an operating steam pressure of 7 barg heating a iquid from 20 C to 80 C? Using the formua: Q c x 1,18 x 60 = = 123 kg/h k = kj/h.m². C assumed k factor for stainess stee. A = 1,18 m² (given by kette manufacturer) Now simpy mutipy by a safety factor of 3 to get 369 kg/h of condensate and seect the proper type and capacity trap. EXAMPLE: Seect a trap for a 1000 iters kette using 0,5 barg steam to heat a product (mik) with a specific gravity of 1,03 and a specific heat of 3,77 kj/kg/ C (Tabe CG-62-1, page CG-62). Starting at room temperature of 20 C, the product wi be heated to 80 C in 30 minutes. Using the formua: x 1,03 kg/m³ x 3,77 kj/kg/ C x 60 C Q c = = 211 kg/h kj/kg x 0,5 h Now simpy mutipy by a safety factor of 3 to get 633 kg/h of condensate and seect the proper type and capacity trap. Based on the standard requirements and probems invoved with fixed gravity drained kettes, the most efficient type trap to use is the inverted bucket. The inverted bucket trap vents air and CO 2 at steam temperature and provides tota efficiency against back pressure. The primary recommendation for titing syphon drained kettes is the automatic differentia condensate controer. In addition to providing the same features as the IB, the DC offers exceent air venting abiity at very ow pressure and exceent fash steam handing abiity. If an IB trap is seected for syphon drained service, use a trap one size arger. Genera Recommendations for Maximum Efficiency Desirabe Cooking Speed. Because the product cooked has such an important bearing on trap seection, a pant with many jacketed kettes shoud conduct experiments using different sizes of traps to determine the size giving best resuts. Steam Suppy. Use steam ines of ampe size to suppy steam to the kettes. Locate the inet nozze high up on the jacket for best resuts. It shoud be sotted so as to give steam fow around the entire jacket area. Instaation Insta traps cose to the kette. You can further increase the dependabiity and air-handing capabiity by instaing a thermostatic air vent at high points in the jacket. See Figs. CG and CG Never drain two or more kettes with a singe trap. Group drainage wi invariaby resut in short circuiting. For an aternative method of determining condensate, use the foowing formua: Q c = V x s.g. x c x Δt r x h x 60 Where: Q c = Condensate oads in kg/h V = Liters of iquid to heated s.g.= Specific gravity of the iquid in kg/m³ c = Specific heat of the iquid in kj/kg/ C Δt = Temperature rise of the iquid C r = Latent heat of the steam in kj/kg (see Steam Tabes, coumn 5 on page CG-10) h = Time in hours for product heating Tabe CG Recommendation Chart (See Page CG-9 for Feature Code References.)

65 How to Trap Cosed, Stationary Steam Chamber Equipment Steam Conservation Guideines Cosed, stationary steam chamber equipment incudes paten presses for the manufacture of pywood and other sheet products, steam jacketed mods for rubber and pastic parts, autocaves for curing and steriizing and retorts for cooking. Product Confined in Steam Jacketed Press Moded pastic and rubber products such as battery cases, toys, fittings and tires are formed and cured, and pywood is compressed and gue-cured in equipment of this type. Laundry fatwork ironers are a speciaized form of press with a steam chamber on one side of the product ony. Trap Seection and Safety Factor The condensate oad for cosed, stationary steam chamber equipment is determined by use of the foowing formua: Q c = A x R x SF Where: Q c = Condensate oad in kg/h A = Tota area of paten in contact with product in m² R = Condensing rate in kg/h/m² (For purposes of sizing steam traps, a 35 kg/h/m² condensing rate may be used) SF = Safety factor EXAMPLE: What is the condensate oad for a mid paten on a press with a 600 x 900 mm paten? Using the formua: Q c = 0,54 m² x 35 kg/h/m² x 3 = 56,7 kg/h End patens woud have haf this oad. The safety factor recommended for a equipment of this type is 3:1. The inverted bucket trap is the recommended first choice on steam jacketed chambers, dryers and ironers because it can purge the system, resist hydrauic shock and conserve energy. Disc and thermostatic type traps may be acceptabe aternatives. Instaation Athough the condensate oad on each paten is sma, individua trapping is essentia to prevent short circuiting, Fig. CG Individua trapping ensures maximum and uniform temperature for a given steam pressure by efficienty draining the condensate and purging the non-condensabes. Direct Steam Injection Into Product Chamber This type of equipment combines steam with the product in order to cure, steriize or cook. Common exampes are autocaves used in the production of rubber and pastic products, steriizers for surgica dressings and gowns, and retorts for cooking food products aready seaed in cans. Trap Seection and Safety Factor Cacuate the condensate oad using the foowing formua: Q c = W x c x Δt r x h Where: Q c = Condensate oad in kg/h W = Weight of the product in kg c = Specific heat of the product in kj/kg/ C (Tabe CG-62-1, page CG-62) Δt = Product temperature rise in C r = Latent heat of steam in kj/kg (see Steam Tabes, coumn 5 on page CG-10) h = Time in hours EXAMPLE: What wi be the condensate oad on an autocave containing 100 kg of rubber product which must be raised to a temperature of 150 C from a starting temperature of 20 C?

66 How to Trap Cosed, Stationary Steam Chamber Equipment Since steam is in contact with the product, you can anticipate dirty condensate. In addition, the vesse is a arge voume chamber that requires specia consideration in the purging of condensate and non-condensabes. For these reasons, an inverted bucket trap with an auxiiary thermostatic air vent instaed at the top of the chamber is recommended. Where no remote thermostatic air vent can be instaed, incorporate the arge voume air purging capabiities in the steam trap itsef. An automatic differentia condensate controer shoud be considered a possibe first choice on arge chambers. As an aternative, an F&T or thermostatic trap shoud be used and be preceded by a strainer, the atter receiving reguar checks for free fow. Instaation Because the steam and condensate is in contact with the product, the trap discharge shoud amost aways be disposed of by some means other than return to the boier. In virtuay a cases this equipment is gravity drained to the trap. However, very often there is a condensate ift after the trap. Because steam pressure is usuay constant, this does not present a probem. For thorough air remova and quicker warm-up, insta a thermostatic air vent at a high point of the vesse. See Fig. CG Product in Chamber Steam in Jacket Autocaves, retorts and steriizers are aso common exampes of this equipment; however, the condensate is not contaminated from actua contact with the product and can be returned directy to the boier. Steam traps with purging abiity and arge voume air venting are sti necessary for efficient performance. Trap Seection and Safety Factor Size steam traps for product in chamber steam in jacket equipment by using the same formua outined for direct steam injection. The safety factor is aso 3:1. The inverted bucket trap is recommended because it conserves steam, purges the system and resists hydrauic shock. Use the IB trap in combination with a thermostatic air vent at the top of the chamber for greater air-handing capabiity. As an aternative, an F&T or thermostatic trap coud be used. On arge chambers, where it s not possibe to insta the air vent, an automatic differentia condensate controer shoud be considered a possibe first choice. Instaation With product in chamber steam in jacket equipment, the steam and condensate do not come in contact with the product and can be piped to the condensate return system.

67 How to Trap Rotating Dryers Requiring Syphon Drainage Steam Conservation Guideines There are two cassifications of rotating dryers which vary significanty in both function and method of operation. The first dries a product by bringing it into contact with the outside of a steam-fied cyinder. The second hods the product inside a rotating cyinder where steam-fied tubes are used to dry it through direct contact. In some appications a steam jacket surrounding the cyinder is aso used. Safety Factor The safety factor for both kinds of dryers depends on the type of drainage device seected. n n If an automatic differentia condensate controer (DC) is instaed, use a safety factor of 3:1 based on the maximum oad. This wi aow sufficient capacity for handing fash steam, arge sugs of condensate, pressure variations and the remova of non-condensabes. The DC performs these functions on both constant and moduated pressure. If an inverted bucket trap with arge vent is used, increase the safety factor in order to compensate for the arge voume of non-condensabe and fash steam that wi be present. Under constant-pressure conditions, use a safety factor of 8:1. On moduated pressure increase it to 10:1. Rotating Steam Fied Cyinder with Product Outside These dryers are used extensivey in the paper, textie, pastic and food industries, where common exampes are dry cans, drum dryers, aundry ironers and paper machine dryers. Their speed of operation varies from 1 or 2 rpm to surface veocities as high as rpm. Operating steam pressure ranges from subatmospheric to more than 14 barg. Diameters can vary from 150 mm or 200 mm to mm more. In a cases syphon drainage is required and fash steam wi accompany the condensate. Trap Seection Condensate oads can be determined by use of the foowing formua: Q c = πd x R x W Where: Q c = Condensate oad in kg/h d = Diameter of the dryer in m R = Rate of condensation in kg/h/m² W = Width of dryer in m EXAMPLE: Determine the condensate oad of a dryer mm in diameter, mm in width and a condensing rate of 35 kg/h/m². Using the formua: Condensate oad = π(1,5) x 35 x 3 = 495 kg/h Based on its abiity to hande fash steam, sugs of condensate and purge the system, a DC is the recommended first choice. An IBLV may be adequate if proper sizing procedures are foowed. Tabe CG Recommendation Chart (See Page CG-9 for Feature Code References.)

68 How to Trap Rotating Dryers Requiring Syphon Drainage Product Inside a Rotating Steam Heated Dryer This type of dryer finds wide appication in meat packing as we as food processing industries. Common exampes are grain dryers, rotary cookers and bean conditioners. Their speed of rotation is reativey sow, usuay imited to a few rpm, whie steam pressure may range from 0-10 barg. These sower rotating speeds permit the condensate to accumuate in the bottom of the coection chamber in practicay a cases. Again, syphon drainage is required and fash steam is generated during condensate remova. Trap Seection The condensate oad generated by these dryers can be determined through use of the foowing formua: Q c = N x L x R x S Where: Q c = Condensate in kg/h N = Number of tubes L = Length of tubes in m R = Condensing rate in kg/h/m² (typica kg/h/m²) S = Outside surface of the pipe in m²/m (see Tabe CG-47-1) EXAMPLE: What wi be the condensate oad on a rotary cooker containing /4" stee pipes 3 m in ength with a condensing rate of 40 kg/h/m²? Using the formua: Q = 30 x 3 m x 40 kg/h/m² x 0,13 m²/m = 468 kg/h A differentia controer is recommended on these dryers for its purging and fash steam handing abiity. The IBLV again requires proper sizing for certain appications. Instaation In a cases, condensate drainage is accompished through a rotary joint, Figs. CG-46-1 and CG The DC shoud then be ocated mm beow the rotary joint with an extended 150 mm dirt pocket. These provide a reservoir for surges of condensate and aso a pocket for entrained scae.

69 How to Trap Fash Tanks Steam Conservation Guideines When hot condensate or boier water, under pressure, is reeased to a ower pressure, part of it is re-evaporated, becoming what is known as fash steam. The heat content of fash is identica to that of ive steam at the same pressure, athough this vauabe heat is wasted when aowed to escape through the vent in the receiver. With proper sizing and instaation of a fash recovery system, the atent heat content of fash steam may be used for space heating; heating or preheating water, oi and other iquids; and ow pressure process heating. If exhaust steam is avaiabe it may be combined with the fash. In other cases, the fash wi have to be suppemented by ive make-up steam at reduced pressure. The actua amount of fash steam formed varies according to pressure conditions. The greater the difference between initia pressure and pressure on the discharge side, the greater the amount of fash that wi be generated. To determine the exact amount, as a percentage, of fash steam formed under certain conditions, refer to page CG-11 for compete information. Trap Seection The condensate oad can be cacuated using the foowing formua: Q c = L - L x P 100 Where: Q c = Condensate oad in kg/h (to be handed by steam trap) L = Condensate fow into fash tank in kg/h P = Percentage of fash EXAMPLE: Determine the condensate oad of a fash tank with kg/h of 7 barg condensate entering the fash tank hed at 0,7 barg. From page CG-11, the fash percentage is P = 10,5%. Using the formua: Q = = kg/h Due to the importance of energy conservation and operation against back pressure, the trap best suited for fash steam service is the inverted bucket type with arge bucket vent. In addition, the IB operates intermittenty whie venting air and CO 2 at steam temperature. In some cases, the foat and thermostatic type trap is an acceptabe aternative. One particuar advantage of the F&T is its abiity to hande heavy start-up air oads. Refer to Chart CG-11-1 (page CG-11) for percentage of fash steam formed when discharging condensate to reduced pressure. Tabe CG Recommendation Chart (See Page CG-9 for Feature Code References.)

It combines the best features of both the IB and F&T and is recommended for arge condensate oads that exceed the separating capabiity of the fash tank. Safety Factor The increased amount of condensate at start-up and the varying oads during operation accompanied by ow pressure differentia dictates a safety factor of 3:1 for trapping fash tanks.

The check vaves in the incoming ines prevent waste of fash when a ine is not in use. The by-pass is used when fash steam cannot be used. Reief vaves prevent pressure from buiding up and interfering with the operation of the high pressure steam traps. The reducing vave reduces the high pressure steam to the same pressure as the fash, so they can be combined for process work or heating.

70 How to Trap Fash Tanks Instaation Condensate return ines contain both fash steam and condensate. To recover the fash steam, the return header runs to a fash tank, where the condensate is drained, and steam is then piped from the fash tank to points of use, Fig. CG-58. Since a fash tank causes back pressure on the steam traps discharging into the tank, these traps shoud be seected to ensure their capabiity to work against back pressure and have sufficient capacity at the avaiabe differentia pressures. Condensate ines shoud be pitched toward the fash tank, and where more than one ine feeds into a fash tank, each ine shoud be fitted with a swing check vave. Then, any ine not in use wi be isoated from the others and wi not be fed in reverse with resutant wasted fash steam. If the trap is operating at ow pressure, gravity drainage to the condensate receiver shoud be provided. Generay, the ocation chosen for the fash tank shoud meet the requirement for maximum quantity of fash steam and minimum ength of pipe. Condensate ines, the fash tank, and the ow pressure steam ines shoud be insuated to prevent waste of fash through radiation. The fitting of a spray nozze on the inet pipe inside the tank is not recommended. It may become choked, stop the fow of condensate, and produce a back pressure to the traps. Low pressure equipment using fash steam shoud be individuay trapped and discharged to a ow pressure return. Large voumes of air need to be vented from the fash tank; therefore, a thermostatic air vent shoud be used to remove the air and keep it from passing through the ow pressure system. Fash Tank Dimensions The fash tank can usuay be convenienty constructed from a piece of arge diameter piping with the bottom ends weded or boted in position. The tank shoud be mounted verticay. A steam outet is required at the top and a condensate outet at the bottom. The condensate inet connection shoud be mm above the condensate outet. The important dimension is the inside diameter. This shoud be such that the upward veocity of fash to the outet is ow enough to ensure that the amount of water carried over with the fash is sma. If the upward veocity is kept ow, the height of the tank is not important, but good practice is to use a height of mm. It has been found that a steam veocity of about 3 m per second inside the fash tank wi give good separation of steam and water. On this basis, proper inside diameters for various quantities of fash steam have been cacuated; the resuts are potted in Chart CG This curve gives the smaest recommended interna diameters. If it is more convenient, a arger tank may be used. Chart CG-49-1 does not take into consideration pressure - ony weight. Athough voume of steam and upward veocity are ess at a higher pressure, because steam is denser, there is an increased tendency for priming. Thus it is recommended that, regardess of pressure, Chart CG-49-1 be used to find the interna diameter. For additiona information on Armstrong fash tanks, see page CRE-256.

71 How to Trap Absorption Machines Steam Conservation Guideines An absorption refrigeration machine chis water for air conditioning or process use by evaporating a water soution, usuay ithium bromide. Steam provides the energy for the concentration part of the cyce and, except for eectric pumps, is the ony energy input during the entire cyce. A steam trap instaed on a steam absorption machine shoud hande arge condensate oads and purge air at ow pressure, moduated conditions. Trap Seection and Safety Factor Determine the condensate oad in kg/h produced by a ow pressure (normay 1 barg or ess) singe-stage steam absorption machine by dividing its rating in kj/h of refrigeration by (the amount of steam in kg/h required to produce a ton of refrigeration). This represents the consumption at the rated capacity of the machine. EXAMPLE: How much condensate wi a singe-stage steam absorption machine with a rated capacity of kj/h produce? Divide the kj/h machine capacity rating by to get the condensate oad kg/h. A 2:1 safety factor shoud be appied to the fu capacity condensate oad, and the steam trap must be capabe of draining this oad, at a 0,1 bar differentia. In other words, the machine in the exampe woud require a trap capabe of handing kg/h of condensate at 0,1 bar, and the capabiity of functioning at the maximum pressure differentia, usuay 1 bar. In comparison, two-stage absorption machines operate at a higher steam pressure of 10 barg. They have an advantage over singe-stage units in that their energy consumption per kj of refrigeration is ess. EXAMPLE: How much condensate wi a two-stage steam absorption machine with a rated capacity of kj/h produce? Divide the kj/h machine capacity rating by to get the condensate oad kg/h. On two-stage steam absorption machines, a 3:1 safety factor shoud be used. Therefore, the exampe requires a steam trap with a capacity of kg/h. At pressures above 2 barg, the trap capacity must be achieved at 1/2 maximum pressure differentia, which in the exampe is 5 bar. At pressures beow 2 barg, the trap capacity must be achieved at 0,15 bar differentia pressure. However, the trap must sti be capabe of operating at a maximum inet pressure of 10 barg. The F&T trap with an integra vacuum breaker is ideay suited for draining both singe- and doube-stage steam absorption machines. It provides an even, moduated condensate fow and energy-conserving operation. An inverted bucket trap with an externa thermostatic air eiminator may aso be acceptabe. Instaation Mount the steam trap beow the steam coi of the absorption machine with a drip eg height of at east 400 mm (Fig. CG-50-1). This ensures a minimum differentia pressure across the trap of 0,1 bar. Whichever trap is used, a standby trapping system is recommended for this service. In the event that a component in the drainage system needs maintenance, the absorption machine can operate on the standby system whie the repairs are being made. This ensures continuous, uninterrupted service. In some cases, very heavy condensate oads may require the use of two traps operating in parae to hande the norma oad.

75 Instaation and Testing of Armstrong Steam Traps Steam Conservation Guideines Before Instaing Run pipe to trap. Before instaing the trap, cean the ine by bowing down with steam or compressed air. (Cean any strainer screens after this bowdown.) Trap Location ABCs Accessibe for inspection and repair. Beow drip point whenever possibe. Cose to drip point. Trap Hookups. For typica hookups, see Figs. CG-54-1 (beow) through CG-57-3, pages CG-56 through CG-57. Shutoff Vaves ahead of traps are needed when traps drain steam mains, arge water heaters, etc., where system cannot be shut down for trap maintenance. They are not needed for sma steam-heated machines a aundry press, for exampe. Shutoff vave in steam suppy to machine is usuay sufficient. Shutoff Vaves in trap discharge ine are needed when trap has a by-pass. It is a good idea when there is high pressure in discharge header. See aso Check Vaves. By-passes (Figs. CG-55-3 and CG-55-4) are not recommended as, if eft open, they wi defeat the function of the trap. If continuous service is absoutey required, use two traps in parae, one as a primary, one as a standby. Unions. If ony one is used, it shoud be on discharge side of trap. With two unions, avoid horizonta or vertica in-ine instaations. The best practice is to insta at right anges as in Figs. CG-56-1 and CG-55-3, or parae as in Fig. CG Standard Connections. Servicing is simpified by keeping engths of inet and outet nippes identica for traps of a given size and type. A spare trap with identica fittings and haf unions can be kept in storeroom. In the event a trap needs repair, it is a simpe matter to break the two unions, remove the trap, put in the spare and tighten the unions. Repairs can then be made in the shop and the repaired trap, with fittings and haf unions, put back in stock. Test Vaves (Fig. CG-54-1) provide an exceent means of checking trap operation. Use a sma pug vave. Provide a check vave or shutoff vave in the discharge ine to isoate trap whie testing.

76 Instaation and Testing of Armstrong Steam Traps Strainers. Insta strainers ahead of traps if specified or when dirt conditions warrant their use. Some types of traps are more susceptibe to dirt probems than others see Recommendation Chart on page CG-9. Some traps have buit-in strainers. When a strainer bowdown vave is used, shut off steam suppy vave before opening strainer bowdown vave. Condensate in trap body wi fash back through strainer screen for thorough ceaning. Open steam vave sowy. Dirt Pockets are exceent for stopping scae and core sand, and eiminating erosion that can occur in ebows when dirt pockets are not provided. Cean periodicay. Syphon Instaations require a water sea and, with the exception of the DC, a check vave in or before the trap. Syphon pipe shoud be one size smaer than nomina size of trap used but not ess than DN15 pipe size. Eevating Condensate. Do not oversize the vertica riser. In fact, one pipe size smaer than norma for the job wi give exceent resuts. Check Vaves are frequenty needed. They are a must if no discharge ine shutoff vave is used. Fig. CG-55-2 shows three possibe ocations for externa check vaves Armstrong inverted bucket traps are avaiabe with interna check vaves, whie disc traps act as their own check vave. Recommended ocations are given in Fig. CG Discharge Line Check Vaves prevent backfow and isoate trap when test vave is opened.

77 Instaation and Testing of Armstrong Steam Traps Steam Conservation Guideines A Safety Drain Trap shoud be used whenever there is a ikeihood that the inet pressure wi fa beow the outet pressure of a primary steam trap, especiay in the presence of freezing air. One such appication woud be on a moduated pressure heating coi that must be drained with an eevated return ine. In the event of insufficient drainage from the primary trap, condensate rises into the safety drain and is discharged before it can enter the heat exchanger. An F&T trap makes a good safety drain because of its abiity to hande arge amounts of air and its simpicity of operation. Safety drain trap shoud be same size (capacity) as primary trap. Figure CG Typica Safety Drain Trap Hookup The proper appication of a safety drain is shown in Fig. CG The inet to the safety drain must be ocated on the heat exchanger drip eg, above the inet to the primary trap. It must discharge to an open sewer. The drain pug of the safety drain is piped to the inet of the primary trap. This prevents the oss of condensate formed in the safety drain by body radiation when the primary trap is active. The safety drain has an integra vacuum breaker to maintain operation when pressure in the heat exchanger fas beow atmospheric. The inet of the vacuum breaker shoud be fitted with a gooseneck to prevent dirt from being sucked in when it operates. The vacuum breaker inet shoud be provided with a riser equa in eevation to the bottom of the heat exchanger to prevent water eakage when the vacuum breaker is operating, but the drip eg and trap body are fooded. Figure CG mm Typica Protection Against Freezing A propery seected and instaed trap wi not freeze as ong as steam is coming to the trap. If the steam suppy shoud be shut off, the steam condenses, forming a vacuum in the heat exchanger or tracer ine. This prevents free drainage of the condensate from the system before freezing can occur. Therefore, insta a vacuum breaker between the equipment being drained and the trap. If there is not gravity drainage through the trap to the return ine, the trap and discharge ine shoud be drained manuay or automaticay by means of a freeze protection drain. Aso, when mutipe traps are instaed in a trap station, insuating the traps can provide freeze protection. A Check Vave Anti-Freeze Precautions. 1. Do not oversize trap. 2. Keep trap discharge ines very short. 3. Pitch trap discharge ines down for fast gravity discharge. 4. Insuate trap discharge ines and condensate return ines. 5. Where condensate return ines are exposed to ambient weather conditions, tracer ines shoud be considered. 6. If the return ine is overhead, run vertica discharge ine adjacent to drain ine to top of return header and insuate drain ine and trap discharge ine together. See Fig. CG NOTE: A ong horizonta discharge ine invites troube. Ice can form at the far end, eventuay seaing off the pipe. This prevents the trap from operating. No more steam can enter the trap, and the water in the trap body freezes. Outdoor instaation to permit ground eve trap testing and maintenance when steam suppy and return ines are high overhead. Drain ine and trap discharge ine are insuated together to prevent freezing. Note ocation of check vave in discharge ine and bowdown vave A that drains the steam main when trap is opened for ceaning or repair. Figure CG Typica F&T Hookup CG-56

78 Instaation and Testing of Armstrong Steam Traps Testing Armstrong Steam Traps Testing Schedue. For maximum trap ife and steam economy, a reguar schedue shoud be set up for trap testing and preventive maintenance. Trap size, operating pressure and importance determine how frequenty traps shoud be checked. Tabe CG Suggested Yeary Trap Testing Frequency Operating Pressure (barg) and above Appication Drip Tracer Coi Process Figure CG Typica DC Hookup Steam Conservation Guideines How to Test The test vave method is best. Fig. CG-54-1 (page CG-54) shows correct hookup, with shutoff vave in return ine to isoate trap from return header. Here is what to ook for when test vave is opened: 1. Condensate Discharge Inverted bucket and disc traps shoud have an intermittent condensate discharge. F&T traps shoud have a continuous condensate discharge, whie thermostatic traps can be either continuous or intermittent, depending on the oad. When an IB trap has an extremey sma oad it wi have a continuous condensate discharge which causes a dribbing effect. This mode of operation is norma under this condition. 2. Fash Steam Do not mistake this for a steam eak through the trap vave. Condensate under pressure hods more heat units kiojoues (kj) per kiogram than condensate at atmospheric pressure. When condensate is discharged, these extra heat units re-evaporate some of the condensate. See description of fash steam on page CG-11 How to Identify Fash: Trap users sometimes confuse fash steam with eaking steam. Here s how to te the difference: If steam bows out continuousy, in a bue stream, it s eaking steam. If steam foats out intermittenty (each time the trap discharges) in a whitish coud, it s fash steam. 3. Continuous Steam Bow Troube. Refer to page CG No Fow Possibe troube. Refer to page CG-58. Listening Device Test. Use a istening device or hod one end of a stee rod against the trap cap and the other end against your ear. You shoud be abe to hear the difference between the intermittent discharge of some traps and the continuous discharge of others. This correct operating condition can be distinguished from the higher veocity sound of a trap bowing through. Considerabe experience is required for this method of testing, as other noises are teegraphed aong the pipe ines. Pyrometer Method of Testing. This method may not give accurate resuts, depending on the return ine design and the diameter of the trap orifice. Aso, when discharging into a common return, another trap may be bowing through, causing a high temperature at the outet of the trap being tested. Better resuts can be obtained with a istening device.

79 Troubeshooting Armstrong Steam Traps Steam Conservation Guideines The foowing summary wi prove hepfu in ocating and correcting neary a steam trap troubes. Many of these are actuay system probems rather than trap troubes. More detaied troubeshooting iterature is avaiabe for specific products and appications consut factory. Whenever a trap fais to operate and the reason is not readiy apparent, the discharge from the trap shoud be observed. If the trap is instaed with a test outet, this wi be a simpe matter otherwise, it wi be necessary to break the discharge connection. Cod Trap No Discharge If the trap fais to discharge condensate, then: A. Pressure may be too high. 1. Wrong pressure originay specified. 2. Pressure raised without instaing smaer orifice. 3. PRV out of order. 4. Pressure gauge in boier reads ow. 5. Orifice enarged by norma wear. 6. High vacuum in return ine increases pressure differentia beyond which trap may operate. B. No condensate or steam coming to trap. 1. Stopped by pugged strainer ahead of trap. 2. Broken vave in ine to trap. 3. Pipe ine or ebows pugged. C. Worn or defective mechanism. Repair or repace as required. D. Trap body fied with dirt. Insta strainer or remove dirt at source. E. For IB, bucket vent fied with dirt. Prevent by: 1. Instaing strainer. 2. Enarging vent sighty. 3. Using bucket vent scrubbing wire. F. For F&T traps, if air vent is not functioning propery, trap wi ikey air bind. G. For thermostatic traps, the beows eement may rupture from hydrauic shock, causing the trap to fai cosed. H. For disc traps, trap may be instaed backward. Hot Trap No Discharge A. No condensate coming to trap. 1. Trap instaed above eaky by-pass vave. 2. Broken or damaged syphon pipe in syphon drained cyinder. 3. Vacuum in water heater cois may prevent drainage. Insta a vacuum breaker between the heat exchanger and the trap. Steam Loss If the trap bows ive steam, the troube may be due to any of the foowing causes: A. Vave may fai to seat. 1. Piece of scae odged in orifice. 2. Worn parts. B. IB trap may ose its prime. 1. If the trap is bowing ive steam, cose the inet vave for a few minutes. Then graduay open. If the trap catches its prime, chances are the trap is a right. 2. Prime oss is usuay due to sudden or frequent drops in steam pressure. On such jobs, the instaation of a check vave is caed for ocation D or C in Fig. CG-55-2 (page CG-55). If possibe, ocate trap we beow drip point. C. For F&T and thermostatic traps, thermostatic eements may fai to cose. Continuous Fow If an IB or disc trap discharges continuousy, or an F&T or thermostatic trap discharges at fu capacity, check the foowing: A. Trap too sma. 1. A arger trap, or additiona traps, shoud be instaed in parae. 2. High pressure traps may have been used for a ow pressure job. Insta right size of interna mechanism. B. Abnorma water conditions. Boier may foam or prime, throwing arge quantities of water into steam ines. A separator shoud be instaed or ese the feed water conditions shoud be remedied. Suggish Heating When trap operates satisfactoriy, but unit fais to heat propery: A. One or more units may be short-circuiting. The remedy is to insta a trap on each unit. See page CG-22. B. Traps may be too sma for job even though they may appear to be handing the condensate efficienty. Try next arger size trap. C. Trap may have insufficient air-handing capacity, or the air may not be reaching trap. In either case, use auxiiary air vents. Mysterious Troube If trap operates satisfactoriy when discharging to atmosphere, but troube is encountered when connected with return ine, check the foowing: A. Back pressure may reduce capacity of trap. 1. Return ine too sma trap hot. 2. Other traps may be bowing steam trap hot. 3. Atmospheric vent in condensate receiver may be pugged trap hot or cod. 4. Obstruction in return ine trap hot. 5. Excess vacuum in return ine trap cod. Imaginary Troubes If it appears that steam escapes every time trap discharges, remember: Hot condensate forms fash steam when reeased to ower pressure, but it usuay condenses quicky in the return ine. See Chart CG-11-1 on page CG-11. CG-58

80 Pipe Sizing Steam Suppy and Condensate Return Lines Definitions Steam mains or mains carry steam from the boier to an area in which mutipe steam-using units are instaed. Steam branch ines take steam from steam main to steamheated unit. Trap discharge ines move condensate and fash steam from the trap to a return ine. Condensate return ines receive condensate from many trap discharge ines and carry the condensate back to the boier room. Pipe Sizing Two principa factors determine pipe sizing in a steam system: 1. The initia pressure at the boier and the aowabe pressure drop of the tota system. The tota pressure drop in the system shoud not exceed 20% of the tota maximum pressure at the boier. This incudes a drops - ine oss, ebows, vaves, etc. Remember, pressure drops are a oss of energy. 2. Steam veocity. Erosion and noise increase with veocity. Reasonabe veocities for process steam are 30 to 60 m/sec, but ower pressure heating systems normay have ower veocities. Another consideration is future expansion. Size your ines for the foreseeabe future. If ever in doubt, you wi have ess troube with oversized ines than with ones that are margina. EXAMPLE: What is the maximum oad capacity of a steam ine with a pressure of 4 bar and a diameter of 50 mm? Reading down the eft hand coumn of Tabe CG-60-1 "Steam Pressure in bar(a)" to 4 and then to the direct right to the coumn for a steam pipe 50 mm in diameter, it is determined that the pipe wi hande 505 kg/h of steam.

81 Pipe Sizing Steam Suppy and Condensate Return Lines Steam Conservation Guideines Tabe CG-60-1 can aso be used to determine the pressure necessary to hande a known quantity of steam. If a 80 mm steam pipe must hande kg/h of steam, how much pressure wi be needed? Reading down the coumn for a steam pipe measuring DN80 unti the figure is reached and then directy to the eft, it is determined that a steam pressure of 16 barg wi be necessary to hande the oad. For quick steam veocity determination, see Tabe CG For an exact measurement, the foowing formua may be used: V = Q x S Where: V = Veocity in m/sec Q = Steam oad in m³/h S = Inside area of pipe in m² (see Tabe CG-59-1). When necessary we can find the pressure drop in a steam ine by using Chart CG EXAMPLE: How much of a pressure drop wi be present in a straight steam ine DN80, 150 m in ength with a oad of kg/h and a pressure of 6 barg, and what wi be the pressure at the end of the ine? Assume an average pressure in the ine of 5,5 barg. From the tabes we find a pressure drop of 38 mm WC/m so the tota pressure drop wi be 150 x 38 = mm WC/m 0,57 bar. Pressure at the end of the main wi then be 6-0,57 = 5,43 barg. Trap Discharge Lines Trap discharge ines are usuay short. Assuming the trap is propery sized for the job, use a trap discharge ine the same size as the trap connections. At very ow pressure differentia between trap and condensate return pipe, trap discharge ines can be increased one pipe size advantageousy. Condensate Return Lines For medium and arge-sized pants, the services of a consutant shoud be empoyed to engineer the condensate return pipe or pipes. Usuay it is considered good practice to seect return pipe one or two sizes arger to aow for 1) increase in pant capacity and 2) eventua fouing of pipe with rust and scae. EXAMPLE: What is the pressure drop in a DN40 condensate return ine with a capacity of 400 kg/h, when the steam pressure is 2 barg and the condensate return ine to atmosphere of 150 m ength? From Tabe CG-61-1 take the capacity factor corresponding to 2 barg = 0,256 and then divide the given oad by this factor: 400 0,256 = kg/h. This is corresponding to a pressure drop of about 2 mm WC/m in a DN 40 pipe. If the condensate ine is 150 m ong, the tota pressure drop is 150 x 2 = 300 mm WC (0,3 barg). Traps and High Back Pressure Back pressures excessive by norma standards may occur due to fouing of return ines, increase in condensate oad or fauty trap operation. Depending on the operation of the particuar trap, back pressure may or may not be a probem. See ine I in Recommendation Chart on page CG-9. If a back pressure is ikey to exist in the return ines, be certain the trap seected wi work against it. Back pressure does ower the pressure differentia and, hence, the capacity of the trap is decreased. In severe cases, the reduction in capacity coud make it necessary to use traps one size arger to compensate for the decrease in operating pressure differentia.

87 Effective Condensate Management = Energy Savings The most basic part of energy management is utiizing a vauabe kj within the steam system. Depending on the pressure, condensate exiting a trap contains approximatey 20% of the heat energy transferred at the boier in the form of sensibe heat. Effective recovery of condensate reduces four tangibe costs of producing steam: Fue/energy costs and CO 2 emissions associated with producing steam Boier water make-up and sewage treatment Boier water chemica treatment Boier bow-down rate These savings can be cacuated using the attached savings form. Returning condensate saves money, energy and the environment. Pour money and energy savings back into your pant not down the drain. Condensate Recovery Savings Anaysis Location Buiding Energy costs wi vary from pant to pant and regions of the word. Vaues shown are conservative. Compete this form using your faciities numbers to determine annua savings in your pant by returning condensate. If some costs are not known, use the figures beow for conservative estimates.

89 Sizing and Seection PT-100/200/300/3500/400 Series The Armstrong non-eectric pump trap is sized based on actua condensate oad (kg/h) being pumped. The foowing steps are used to size the pump. 1. Determine the tota condensate oad to be pumped in kg/h. See conversion factors tabes on specific product page. 2. Determine the tota back pressure the pump wi operate against. Tota back pressure is the sum of the foowing: Vertica ift expressed in barg (10 m ift = 1 barg). Existing pressure in condensate return ine or D.A. tank Frictiona oss from pipe, vaves and fittings 3. Determine type of motive gas to be used (steam, air or other inert gas) and pressure avaiabe. Exampe: Condensate oad = kg/h. Tota back pressure = 1,5 barg (5 m vertica ift = 0,5 barg, 1 barg in condensate return ine). Motive pressure is steam at 3,5 barg. Soution: Mode EPT-206 Find 1,5 barg tota ift or back pressure in coumn two of EPT-200 Pumping Trap Capacities tabe on page CRE-221. Then find 3,5 barg motive pressure in coumn one. Move across the capacity tabe unti you reach a mode number with the correct capacity. An EPT-206 has been highighted above for this exampe. Either a cosed reservoir pipe or a vented receiver is required for proper condensate storage during the pump-down cyce of the pumping trap. For vented / open system receiver sizing: Determine the pressure from where the condensate is being discharged. Determine condensate oad. Reference Percentage of Fash Steam chart on page CRE-230 to find the pressure that corresponds with the discharge condensate pressure. For this exampe, use 1,0 barg. Foow 1,0 barg on the horizonta axis where it intersects the curve. Move eft from the intersecting ines to the vertica axis for the percentage of fash steam that is created. For this exampe it wi be 3% (see shaded area on Percentage of Fash Steam chart). Mutipy 3% by the condensate oad. Using exampe above: kg/h x 0,03 = 33 kg/h fash steam Using the Vented Receiver Sizing tabe CRE on page CRE-230, find the amount of fash steam in coumn one. Foow the tabe across to determine the size of the vented receiver. (See shaded area on Vented Receiver Sizing tabe CRE for this exampe.) For cosed reservoir piping: Determine condensate oad (using exampe above kg/h). Reference the inet reservoir pipe sizing tabe CRE for cosed systems on page CRE-230. Find kg/h in coumn one.

The pump trap is ocated downstream and beow the vented receiver, aowing for proper fi head height. See tabe CRE for vented receiver and vent sizing for an open system.

Note that a steam trap is not required in this appication, as differentia pressure is aways negative. For more detais, see instaation and operation manuas. Lift CLOSED SYSTEMS Appications exist where it is desirabe to tie the vent ine back into the heat exchange space, equaizing the pressure in the heat exchanger, reservoir/piping and the pump trap. This aows water to fow by gravity down to the pump where it can be returned. Vauabe kj remain within the system due to no fash steam oss to the atmosphere through the vent. Cosed system appications can aso be used to drain iquid from the equipment under a vacuum. See tabe CRE for reservoir pipe sizing. Note 1: If steam motive is used, the drip trap may be discharged into the return ine or to the drain. Note 2: Vent piping from the pump trap can be connected to the inet side of the equipment being drained if the pressure drop across the equipment is ess than 0,03 bar and there is a minimum of 600 mm of fi head present. Note 3: A vacuum breaker might be instaed to protect the heat exchanger if the vent piping from the pump trap is connected to the receiver. If the equipment moduated down to a subatmospheric condition, the vacuum breaker wi open to equaize the system and provide adequate drainage. CRE-214

92 Condensate Drainage From Temperature Controed Equipment Condensate Recovery Equipment Probem: Sta Condition on Moduated Steam Contro Moduated steam contros are required to change steam pressure in the heat exchanger to contro accurate product output temperature. Due to these varying steam pressure changes, a sta condition exists in a heat exchangers where condensate cannot fow through the steam trap due to insufficient or even negative pressure differentia. Under the sta condition, partia or compete fooding wi occur. Reference figure above noting the sta conditions and probems that can occur. Armstrong Soution The combination of Armstrong pump trap and Armstrong steam trap is the tota soution to the sta condition by removing condensate under a system conditions. When the steam system pressure is sufficient to overcome the back pressure, the steam trap operates normay. When the system pressure fas to the sta condition, the pump trap operates and pumps condensate through the steam trap. Temperature contro and condensate drainage are assured under a system conditions. Note: The pump trap is sized for the sta conditions. Probems 1. Sta condition no condensate drainage due to insufficient pressure to move condensate through the steam trap 2.

134 GD-22 Posi-Pressure Draining System For Heat Exchangers up to 500 kg/h of Steam Forget About Fooded Heat Exchangers The major cause of fooded heat exchangers is a ack of sufficient pressure differentia across the steam trap under moduated steam conditions. With Armstrong s Posi-Pressure Contro System, there is aways a minimum preset differentia pressure between the heat exchanger and the condensate return system. Even if the pressure in the condensate return changes, the Posi-Pressure Controer automaticay adjusts to maintain the preset differentia. Condensate Recovery Equipment Forget About Water Hammer When heat exchangers food, steam and cod condensate frequenty come in contact with each other. When this happens, the steam rapidy condenses, causing water hammer. This water hammer condition can cause damage to heat exchangers, piping and fittings. By eiminating heat exchanger fooding, the Posi-Pressure Contro System wi sove the probem. Forget About Frozen Steam Cois Most steam cois freeze because they are fooded with condensate. Costy buky and high maintenance face and by-pass coi systems were created to sove this probem by maintaining a positive differentia steam pressure. Now, with Armstrong s Posi-Pressure Contro System, simpe and inexpensive moduated contro systems can do the same job. However, we must caution that proper steam coi design, steam trapping and venting practices are aso required for freeze protection. If assistance is needed, Armstrong s Representatives are trained to anayze your tota steam system and offer you soutions to your probems.

135 GD-22 Posi-Pressure Draining System For Heat Exchangers up to 500 kg/h of Steam How Does the Posi-Pressure Contro System Work? A norma steam system may moduate into a vacuum to contro temperature. A vacuum breaker is often instaed to prevent this condition. Once the vacuum breaker opens, temperature contro is accompished by mixing the air with the steam. The steam/air mixture resuts in a ower temperature. However, even a vacuum breaker wi not work if condensate has to be eevated to an overhead return, or if the return system is pressurized. The Posi-Pressure Contro System acts as a vacuum breaker. Instead of introducing air at atmospheric pressure, the controer injects air at an eevated pressure into the heat exchanger. The user presets the eve of eevated air pressure at the time of instaation. Rather than a specific pressure, the controer maintains a specific differentia pressure across the steam trap. Even if a steam trap fais or other causes change the condensate return pressure, the controer wi sense this difference and maintain the preset differentia. How Much Air Wi Be Used? The Posi-Pressure Contro System uses very itte air. The amount depends upon the size of the steam trap seected. Air usage can vary from as itte as 0,3 to 2,5 Nm³/h or more on arge systems. Once the initia air is introduced, ony the eakage through the arge vent bucket in the steam trap must be added. This air voume is so ow that it is practicay undetectabe in a deaerator. Are There Any Other Advantages? Yes! It is generay recommended that foat and thermostatic traps be used on moduated steam systems because they drain better when there is no motive pressure other than the static head of condensate. With a positive pressure aways being maintained by the Posi-Pressure Contro System, an inverted bucket steam trap with its inherent onger ife expectancy can, and must, be used. Since air is injected at a positive pressure, carbon dioxide (the rea cause of corrosion) is diuted and swept cear of the heat exchanger.

144 1-LDC A See-Thru Body So You Know When It s Working Benefits You Can See Reduced maintenance Stainess stee internas mean corrosion resistance and reduced maintenance. Efficient operation Simpe ba foat mechanism discharges ony when iquid is present so it doesn t waste air. Positive seating Free-foating vave mechanism assures positive seating so it prevents air oss. There are no fixed pivots to wear or create friction, and wear points are heaviy reinforced for ong ife. An inside ook See-thru body means you can observe changing conditions as they occur. See a probem in the making instead of having to dea with it after the fact. In-ine repairabiity In-ine connections and an O-ring sea make for quick, easy repairs without dismanting piping. Just unscrew and remove the body for maintenance. Corrosion resistance Long-asting poysufone body and reinforced nyon cap weigh ess than 20% of cast iron iquid drain traps. Rugged poysufone resists corrosion and provides ong, troube-free service ife. Liquid Drainers Reduced need for ceaning Recessed dirt pocket gives dirt a pace to accumuate away from the vave seat. Vave seat is 32 mm above the dirt pocket. Compared to other ba foat drain traps, the Armstrong 1-LDC reduces dirt fouing and needs ess frequent ceaning. Simpified instaation Optiona horizonta or vertica inet with horizonta outet eiminates the need for extra fittings. Makes instaation in existing systems easier. Vertica inet is 3/4" to accommodate air venting. Requires no eectricity. Note: The Armstrong 1-LDC is not recommended for extremey dirty systems or those with heavy oi carryover. The drain trap shoud not be used in an environment where there are high eves of ketones or chorinated or aromatic hydrocarbons. LD-458

145 1-LDC A See-Thru Body So You Know When It s Working Now, you can iteray see what you ve been missing the eary warning signs of a drain trap or system probem. Since you know the operating condition of a drain trap, you won t waste time and money scheduing maintenance that isn t needed. In other words, you wi be abe to react to a condition before it becomes a probem. A simpe ba foat mechanism requiring no eectricity to operate, the new Armstrong 1-LDC discharges automaticay ony when iquid is present. That means no air oss as with timed devices, which open even when iquid is not present. Moisture in a compressed air system causes a variety of probems everything from dirt fouing and potentia corrosion to water hammer. Getting the water out automaticay, reiaby buids greater efficiency into your system. In short, pay attention to your com-pressed air system, and you probaby pay ess to compress air. Compare and Save the Difference Seeing reay is beieving especiay when you compare the Armstrong see-thru drain trap with cast iron units. Measure the differences in the time and money you can save with a more efficient, easier-to-maintain compressed air system. For more information or technica assistance, contact your oca Armstrong Representative. Liquid Drainers LD-459

158 High Leverage Spring-Loaded Ba Foat Type Drain Traps For Low Fows at Pressures to 255 bar and Specific Gravity Down to 0,40 The Armstrong High Leverage Series of iquid drain traps was deveoped especiay for draining ow specific gravity fuids from gases at high pressures. They use standard Armstrong forged stee bodies with very high everage systems and spring assist. Note: Modes 2313-HLS, 2316-HLS, 2413-HLS and 2415-HLS are aso avaiabe with cast T-316 stainess stee body and astainess stee internas. Consut factory. Sour Gas Service Forged stee and stainess stee traps can be modified to resist hydrogen sufide stress corrosion. These modifications invove anneaing the foat, which wi reduce the maximum working pressure of the foat to about haf its norma vaue. Consut Armstrong Appication Engineering for aowabe working pressures. Because of design considerations in this drain trap, it is essentia that a safety factor of at east 2 be appied to the peak iquid oad for sizing purposes. Do not use HLS drain traps on steam service.

160 Free Foating Lever Dua Gravity Drain Traps For Pressures to 69 bar Armstrong free foating ever dua gravity drain traps are identica to the units described on pages LD-465 and LD-469 except foat weights are modified to make them suitabe for draining water from a ight iquid. If you wish to use them for draining any iquid with specific gravity other than 1,00, consut the Armstrong Appication Engineering Department. Foats for dua gravity drain traps are weighted with quenching oi which, in the unikey possibiity of foat faiure, may be dispersed through the system. If this is a hazard, consut the Armstrong Appication Engineering Department. Note: Armstrong can design dua gravity traps for venting ight iquids from above heavier iquids. Consut the Armstrong Appication Engineering Department. Viscosity Considerations for Dua Gravity Traps The operation of dua gravity traps depends upon a foat that wi sink in the ight iquid and foat in the heavy iquid. When the specific gravities of the two iquids are very cose, the avaiabe operating forces are, therefore, aso very sma. Viscous fuids may impair the abiity of the trap to respond to changing iquid eves. Consut Armstrong s Appication Engineering Department if your appication invoves fuids more viscous than 70 cs, which is approximatey the viscosity of a ight machine oi.

163 Instaation and Maintenance of Drain Traps For Draining Liquid From Gas...for Draining Water From Light Liquid Instaation Procedures Pipe Fitting. Adhere to good piping practice. Cean pipes carefuy after cutting and threading before hooking up traps. Before connecting traps to system, bow down at fu pressure to cear the pipes of dirt, pipe cuttings and other foreign objects. Strainers are necessary if there is a chance scae and sediment can be carried to the trap. Bowdown Vaves may prove usefu. Shutoff Vaves & Unions shoud be provided so the drain trap can be examined and/or serviced without shutting down the unit drained. Operation. Maximum operating pressure is stamped on the trap. Do not exceed this pressure. A. Ba foat drain traps must be ocated beow the drain point. B. Make inet piping as short as possibe with a minimum of ebows and other restrictions. C. Back venting usuay required on ba foat drain traps. 1. Pressure vesses shoud be vented back to any convenient point above the iquid eve. Use a fu-ported vave in the back-vent ine. On arger traps (6 and 36-LD and arger) use a minimum of 3/4" nomina pipe for back venting 1" or arger preferred for heavy oads. Remember, the pressure in the unit drained and in the drain trap are the same ony the difference in iquid eves produces fow. 2. Separators and drip points shoud be vented to the downstream side of the unit. 3. On very ight oads, venting is not necessary; but use at east a 3/4" connection between the vesse and the trap. Make sure inet ine is vertica or pitched to trap. 4. Foat type drain traps do not require priming. Typica instaations of drain traps are shown in drawings in How to Hook Up Armstrong Drain Traps section. Drain Trap Testing and Troubeshooting Testing Schedue A reguar schedue shoud be set up for testing and preventive maintenance. Size and operating pressure determine how frequenty drain traps shoud be checked. Units on norma industria appications shoud be checked as foows: High Pressure Drain Traps 17 bar and up. Test daiy to weeky. Medium Pressure Drain Traps 4 to 17 bar. Test weeky to monthy. Low Pressure Drain Traps 0,07 to 4 bar. Test monthy to annuay. Large traps on high capacity jobs can be tested more frequenty to good advantage. Drain Traps on gas and other critica appications shoud be checked at the same time vaves and other ine equipment are inspected. Your own experience wi determine the required testing schedue. Troubeshooting A. Drain trap does not discharge. 1. Insufficient iquid coming to drain trap to permit discharge. Continue operation. 2. Drain trap fied with dirt or sudge. Remove cap and mechanism; cean thoroughy. Insta strainer in inet side of drain trap. 3. Differentia pressure across drain trap too high. Check inet and outet pressure. If the difference exceeds the maximum operating pressure stamped on the drain trap, the vave wi remain cosed. Reduce differentia pressure if possibe, or insta propery sized mechanism in drain trap if possibe. 4. Worn vave seat. As the seat becomes worn, the seating surface area enarges, owering the trap s maximum operating pressure. Repace with new parts. 5. Inet or outet ine vaves cosed. Open vaves. 6. Strainer cogged. Cean strainer screen. 7. Foat defective or coapsed. Repace foat. B. Drain trap discharges continuousy. 1. If drain trap discharges fu stream of iquid continuousy and vesse fis fu of iquid a. Drain trap too sma for job. Repace with correct size. b. Abnorma amounts of iquid coming to drain trap. Remedy cause or repace with drain trap that has a arger capacity and wi hande peak oads. C. Drain trap bows through. 1. Dirt or scae on vave or seat. Remove cap, cean drain trap, as we as vave and seat. 2. Worn vave, or seat that is wire-drawn. Remove cap, repace mechanism. 3. IB trap may ose its prime. a. Cose the inet vave for a few minutes. Then graduay open. If the drain trap catches its prime, the chances are that the trap is a right. b. Frequent oss of prime may require an interna check vave or, if trap is od, vave and seat may be worn. In the event of any unusua maintenance or operationa difficuty, consut your Armstrong Representative, or the Armstrong Internationa Appication Engineering Department. Liquid Drainers LD-477

164 Instaation and Maintenance of Drain Traps For Draining Liquid From Gas...for Draining Water From Light Liquid Instaation of Armstrong drain traps for the most satisfactory operation requires that a few simpe rues be observed: Cean Piping. First insta piping and vave ahead of trap, then bow down at fu air pressure to remove oose dirt. Last of a, screw the trap into position. Location. Compressed drain traps shoud be ocated beow and cose to the unit being drained (See Figures LD and LD ), or as directed by the equipment manufacturer. When headroom is inadequate, inverted bucket drain traps can be instaed above the unit drained, but they must be equipped with a check vave in the inet ine (See Fig. LD-478-2). They shoud be accessibe for maintenance. Priming. Prime bodies of inverted bucket drain traps before turning on the air. Ba foat traps do not require priming. Back Venting (Ba Foat Traps Ony). Ordinariy a drain trap has itte water to hande, and a singe ine to the top of the trap is sufficient. However, if a ba foat trap must be instaed at some distance from the drip point, or if there are arge quantities of water to be discharged, back venting is good insurance for positive and fast fow of water to the drain. See Fig. LD Be sure there are no pockets in the vent ine in which water coud coect and prevent venting. See Fig. LD If high water eve is objectionabe, raise the receiver, or dig a pit so top of trap can be at the same eve as the bottom of the drain ine. See Fig. LD Otherwise, use an inverted bucket trap that can be instaed above the drip point. See Fig. LD Liquid Drainers Figure LD Standard hookup for inverted bucket drain trap BVSW. Be sure to fi trap body with water before opening the vave. Figure LD The inverted bucket trap draining an air receiver where space imitations prevent instaation beow the receiver. Note trap shoud either have interna check vave or a swing check to prevent prime oss when air pressure drops. LD-478

169 Compressed Air/Gases Basic Concepts Moisture is aways present in compressed air, and oi can be present at some points in a compressed air system. For the efficient operation and ong ife of gaskets, hoses and air toos, this excess moisture and the oi must be removed from the system. The remova of moisture and oi from a system invoves more than just traps. To maintain high efficiency and avoid costy probems, a compressed air system aso requires: 1. Aftercooers to bring the compressed air down to ambient or room temperature. 2. Separators to knock down suspended dropets of water or fog. Separators are instaed downstream from aftercooers or in air ines near point of use, or both. 3. Drain traps to discharge the iquid from the system with a minimum oss of air.

170 Compressed Air/Gases Basic Concepts Water carried with air into toos or machines where air is being used wi wash away ubricating oi. This causes excess wear to motors and bearings and resuts in high maintenance expense. Without adequate ubrication, the toos and machines run suggishy and their efficiency is owered. This effect is particuary pronounced in the case of pneumatic hammers, dris, hoists and sand rammers, where the wearing surfaces are imited in size and the excessive wear creates air eakage. Where air is used for paint spraying, enameing, food agitation and simiar processes, the presence of water and/or oi cannot be toerated, nor can partices of grit or scae. In instrument air systems, water wi tend to cing to sma orifices and coect dirt, causing erratic operation or faiure of sensitive devices. Pipeine Troubes When water accumuates at ow points in the pipeine, the aircarrying capacity of the ine is reduced. Eventuay, airfow over the poo of water wi begin to carry the water aong at high veocity. This produces water hammer aong the ine, and may even carry over a sug of water into a too. In cod weather, accumuations of water may freeze and burst pipeines. Air s Capacity to Hod Moisture At atmospheric pressure (1 bar), 8 m³ of air with an RH of 50% and a temperature of 20 C wi contain 68 g of moisture vapor. When the pressure is doubed (without increasing the temperature) the voume is cut in haf (4 m³), but there are sti 68 g of moisture. This means the reative humidity is now 100% a the moisture in vapor form that it can hande. Increasing the pressure to 8 bar(a), the voume of air is further reduced to approximatey 1 m³. This 1 m³ of compressed air sti at 20 C can hod a maximum 17 g of moisture. The other 51 g of moisture are condensed. 17 g 51 g Pudde Guideines for Draining Liquids Figure LD Pressure: 1 bar(a) Temp: 20 C Air = 8 m³ Moisture = 68 g Max Possibe = 136 g Figure LD Pressure: 2 bar(a) Temp: 20 C Air = 4 m³ Moisture = 68 g Max Possibe = 68 g Figure LD Pressure: 8 bar(a) Temp: 20 C Air = 1 m³ Moisture = 68 g Max Possibe = 17 g 51 g of Liquid LD-431

171 Compressed Air/Gases Basic Concepts Drainage Probems and How to Avoid Them Oi. A critica drainage probem exists at points where oi may be present in the compressed air (principay at intercooers, aftercooers and receivers). Two facts create this probem: 1. Oi is ighter than water and wi foat on top of water. 2. Compressor oi when cooed tends to become thick and viscous. The beaker simuates any drain trap that has its discharge vave at the bottom, Fig. LD Like the beaker, the trap wi fi with heavy oi that may be thick and viscous. Compare with Fig. LD-432-2, which shows an identica beaker except that the discharge vave is at the same eve as the oi. Oi wi escape unti the oi eve is so thin that for every 19 drops of water and one of oi that enter the beaker, exacty 19 drops of water and one drop of oi wi eave. The beaker aways wi be fied with water. The concusion is obvious. When there is an oi-water mixture to be drained from an air separator or receiver, use a trap with the discharge vave at the top. Dirt and Grit. Whie scae and sediment is sedom a probem between the compressor and receiver, it is encountered in the air distribution system, particuary when the piping is od. In this situation, scae wi be carried to a drain trap aong with the water. If the drain trap is not designed to hande dirt and grit, the trap may fai to drain water and oi, or the trap vave may not cose. Figure LD If a beaker coecting oi and water is drained from the bottom at the same rate that oi and water enter, it wi eventuay fi entirey with oi because oi foats on water. Figure LD If a beaker coecting oi and water is drained from the top at the same rate that oi and water enter, it soon wi be entirey fied with water because the oi foats on the water. Air Loss. Often in compressed air systems, the soution to one probem may aso cause another probem. For exampe, a common method of draining unwanted moisture is to crack open a vave; however, this aso creates a eak. The immediate probem is soved, but the soution has an obvious, and usuay underestimated, cost of continua air oss. Figure LD Drain Trap Locations in a Compressed Air System The use of drain traps is an effective way to remove water that coects in many paces in a compressed air system. Each trap ocation must be considered individuay. Guideines for Draining Liquids How much air is ost depends on orifice size and ine pressure (see Tabe LD-433-1). The overa resut is a decrease in ine pressure, the oss of up to a third of the system s compressed air, and the cost of compressing it. Leak contro invoves: n Looking for eaks during shut-down with an utrasonic eak detector n Determining tota eakage by observing how fast pressure drops with the compressor off, both before and after a eak survey n Fixing eaks at joints, vaves and simiar points n Repacing cracked-open vaves with drain traps n Checking the system reguary Entering Air Suction Two-stage Compressor Intercooer Pump 1st 2nd Air Trap Air Aftercooer Water Separator Trap Trap Water Chier LD-432

172 Compressed Air/Gases Basic Concepts Drainage Methods Manua. Liquid may be discharged continuousy through cracked-open vaves, or periodicay by opening manuay operated drain vaves. Open drains are a continuous waste of air or gas and the energy to produce it. A vave manuay opened wi be eft open unti air bows freey. Frequenty, however, the operator wi deay or forget to cose the vave, and precious air or gas is ost. Automatic. Automatic drainage equipment that is adequate for the system is sedom incuded in the origina system. However, subsequent instaation of automatic drain traps wi significanty reduce energy and maintenance costs. Drain Traps. Water coected in separators and drip egs must be removed continuousy without wasting costy air or gas. In instances where drain traps are not part of the system design, manua drain vaves are usuay opened periodicay or eft cracked open to drain constanty. In either case, the vaves are opened far enough that some air and gas are ost aong with the iquid. To eiminate this probem, a drain trap shoud be instaed at appropriate points to remove iquid continuousy and automaticay without wasting air or gas. The job of the drain trap is to get iquid and oi out of the compressed air/gas system. In addition, for overa efficiency and economy, the trap must provide: n Operation that is reativey troube-free with minima need for adjustment or maintenance n Reiabe operation even though dirt, grit and oi are present in the ine n Long operating ife n Minima air oss n Ease of repair Tabe LD Cost of Various Size Air Leaks at 6 barg Orifice Diameter (in) 3/8" 1/4" 1/8" 7/64" 5/64" 1/16" Leakage Rate m³/h 234,5 103,6 26,2 20,0 10,2 6,5 Tota Cost Per Month in 1 207,50 533,75 134,75 103,25 52,50 33,60 Cost Tota Per Year in End of Main To Equipment Air Fiter Receiver Trap Dryer Trap Trap Trap Trap Outdoors Trap Trap Trap Guideines for Draining Liquids LD-433

173 Inverted Bucket Drain Traps For Heavy Oi/Water Service BVSW inverted bucket drain traps are designed for systems with heavy oi or water services. An inverted bucket is used because the discharge vave is at the top, so oi is discharged first and the trap body is amost competey fied with water at a times. BVSW stands for Bucket Vent Scrubbing Wire. This 1,6 mm diameter wire swings freey from the trap cap and extends through the bucket vent. Its function is to prevent reduction of vent size by buidup of soids or heavy oi in the vent itsef. The up-and-down motion of the bucket reative to the vent scrubbing wire keeps the vent cean and fu size. Operation of Inverted Bucket Drain Traps 1. Since there is sedom sufficient accumuation of water to foat the bucket and cose the vave, the trap must be primed on initia start-up or after draining for ceaning. Step 1 shows after operating primed condition with oi in the top of bucket and a very thin ayer of oi on top of water in the trap body. 2. When vave in ine to trap is opened, air enters bucket, dispacing iquid. When bucket is two-thirds fu of air, it becomes buoyant and foats. This coses the discharge vave. As bucket rises, the vent scrubbing wire removes oi and any dirt from bucket vent. Both iquid and air in trap are at fu ine pressure, so no more iquid or air can enter trap unti some iquid or air escapes through the discharge vave. Static head forces air through bucket vent. The air rises to top of trap and dispaces water that enters bucket at bottom to repace air that passes through vent. Just as soon as bucket is ess than two-thirds fu of air, it oses buoyancy and starts to pu on vave ever as shown in Step 3. Figure LD Operation of the BVSW Inverted Bucket Drain Trap Guideines for Draining Liquids Water Oi Air Bubbes Air Under Pressure 1. Trap primed, air off, bucket down, trap vave open. 2.

174 Inverted Bucket Drain Traps 3. Note that iquid eve at top of trap has dropped and the iquid eve in the bucket has risen. The voume of water dispaced by air exacty equas the voume of water that entered the bucket. During this vave-cosed part of the operating cyce Steps 2 and 3 water and oi are coecting in the horizonta ine ahead of the trap. When the bucket is about two-thirds fu of iquid, it exerts enough pu on ever to crack open the discharge vave. 4. Two things happen simutaneousy. a) The accumuated air at top of trap is discharged immediatey, foowed by oi and any water that enters the trap whie the vave is cracked. b) Pressure in trap body is owered sighty, aowing accumuated iquid in horizonta ine to enter the trap. Air dispaces iquid from the bucket unti it foats and coses the discharge vave, restoring the condition shown in Step When fu buoyancy is restored, the trap bucket is two-thirds fu of air. Oi that has entered whie trap was open fows under bottom of bucket and rises to top of water in trap body. The trap normay discharges sma quantities of air severa times per minute. Guideines for Draining Liquids 3. Water enters bucket to repace air passing through bucket vent. This increases weight of bucket unti 4. pu on ever cracks vave. Air at top of trap escapes, foowed by oi and water. Liquid in pipe ahead of trap enters bucket foowed by air. 5. Air dispaces iquid and excess oi from bucket, restoring condition shown in Step 2. LD-435

175 Foat Type Drain Traps Cosed Foat Hoow, thin-wa meta foats are attached through inkages to vaves at the trap bottom, and a seat with an appropriatey sized orifice is inserted at the trap outet. Foats are seected to provide adequate buoyancy to open the vave against the pressure difference. Discharge usuay is to atmosphere, so the pressure drop is equa to the system air pressure. The foat and inkage are made of stainess stee, and the vave and seat are hardened stainess stee for wear resistance and ong ife. The body is cast iron, stainess stee, or cast or forged stee depending on gas pressure. Bodies may be made of stainess stee to resist corrosive gas mixtures. Entering iquid drops to the bottom of the body. As iquid eve rises, the ba is foated upward, thereby causing the vave to open sufficienty that outet fow baances inet fow. Subsequent change of incoming fow raises or owers water eve further opening or throtting the vave. Thus discharge is proportionay moduated to drain iquid competey and continuousy. However, gas fow may be constant or it may abrupty change depending on system demand characteristics. Liquid formation may be sporadic, or the nature of fow generation may cause surges. At times, fow wi be very ow, requiring operation to throtte the fow or even tight shut-off. Tightness of cosure, gas eakage and trap cost wi depend on the design of inkage and vave. Free Foating Lever The discharge from the Mode 1-LD is continuous. The opening of the vave is just wide enough to remove the iquid as fast as it comes to the trap. Thus, at times, the vave is barey cracked from its seat. Water Figure LD Operation of the Mode 1-LD Free Foating Lever Drain Trap As water begins to fi the body of the trap, the foat rises, opening the discharge vave. Motion of the free foating vave ever is guided to provide precise cosure. Guideines for Draining Liquids Free Foating Linkage Vave A hemispherica ba-shaped vave is attached to inkage which is suspended freey on two guide pins. There is no fixed pivot or rigid guides; therefore, the attachment is oose. There are no critica aignments, and the ever and vave may move in a directions. Consequenty, the ever may move the vave to the seat in any aignment. As the vave approaches the seat, the pressure pushes the round vave into the square edge orifice of the seat, effecting a ine sea to attain bubbe-tight cosure. Figure LD Free Foating Linkage LD-436

176 Foat Type Drain Traps Fixed Pivot Conica Vave A conicay shaped vave is attached to a fixed pivot everage system. The fixed pivot does not aow the vave to move freey to conform to the seat for tight cosure. Thus, it may not sea tighty, and some oss of air or gas may be expected. Water Figure LD Operation of Mode 21 Fixed Pivot Drain Trap As the water eve rises, the ba foat cracks the vave to drain iquid at the same rate that it reaches the trap. Changes in the rate of fow to the trap adjust the foat eve and the degree of opening of the vave. Snap Action Vave Because of the sporadic iquid fow, much of the time the vave in a standard foat-type drainer is ony sighty opened. If there is fine dirt or grit in the iquid, partices may accumuate and cog the partiay open vave, or they may odge between the vave and seat, preventing cosure. To overcome this, a specia toggespring operated vave is used. A fat spring attached to the everage system hods the vave cosed unti iquid eve is high enough for the buoyancy to exceed the spring force. Then the vave is snapped open, and the accumuated dirt and grit can be fushed through the wide open vave. When the body is neary empty, buoyancy is reduced enough to permit the spring to snap the vave cosed. Figure LD Operation of Mode 71-A Snap Action Drain Trap Water Guideines for Draining Liquids Cosed About to Open Open Fiing Cyce. Trap vave has just cosed. Spring bowed to right. Foat rides high in water because no force is exerted on spring. As water enters, foat rises, storing energy in spring. This increases submergence of foat. Foat now is more than haf submerged and spring has assumed a handebar mustache shape. Energy stored in spring is due to increased dispacement of water. A very sight rise in water eve causes spring to snap to the eft Instanty the vave opens wide. This reeases energy from spring and foat again rides high in water. As water eve drops, weight of foat bends spring to right, causing snap cosing of vave before a the water has been discharged. LD-437

177 Drain Trap Seection To obtain the fu benefits from the traps described in the preceding section, it is necessary that the correct size and pressure of drain trap be seected for each job, and that it be propery instaed and maintained. Rey on Experience. Most drain traps are seected on the basis of experience. This may be: n Your persona experience n The experience of your Armstrong Representative or distributor n The experience of thousands of others in draining identica equipment Do-It-Yoursef Sizing is required at times. Fortunatey, drain trap sizing is simpe when you know or can figure: 1. Liquid oads in kg/h. 2. Pressure differentia. 3. Maximum aowabe pressure. 1. Liquid Load. Each How To section of this handbook contains formuas and usefu information on proper sizing procedures and safety factors. Operating differentia. When the pant is operating at capacity, the pressure at the trap inet may be ower than main pressure. And the pressure in the return header may go above atmospheric. If the operating differentia is at east 80% of the maximum differentia, it is safe to use maximum differentia in seecting traps. IMPORTANT: Be sure to read the discussion on page LD-439, which deas with ess common, but important, reductions in pressure differentia. 3. Maximum Aowabe Pressure. The trap must be abe to withstand the maximum aowabe pressure of the system, or design pressure. It may not have to operate at this pressure, but it must be abe to contain it. As an exampe, the maximum inet pressure is 10 barg and the return ine pressure is 1 barg. This resuts in a differentia pressure of 9 bar; however, the trap must be abe to withstand 10 barg maximum aowabe pressure. See Fig. LD Pressure Differentia. Maximum differentia is the difference between main pressure, or the downstream pressure of a PRV, and return ine pressure. See Fig. LD The drain trap must be abe to open against this pressure differentia. Guideines for Draining Liquids Differentia Pressure or Maximum Operating Pressure (MOP) A B Inet Pressure or Maximum Aowabe Pressure (MAP) Trap Back Pressure or Vacuum Figure LD A minus B is Pressure Differentia: If B is back pressure, subtract it from A. If B is vacuum, add it to A. LD-438

178 Drain Trap Seection Factors Affecting Pressure Differentia Pressure Differentia in Detai Inet Pressure can be: 1. Air main pressure. 2. Reduced pressure controed by a pressure reducing vave station. Discharge can be: 1. Atmospheric. 2. Beow atmospheric under vacuum. Add vacuum to inet pressure to get pressure differentia. 102,4 mm Hg vacuum = approximatey 0,1 bar of pressure beow atmospheric. 3. Above atmospheric due to: a. Pipe friction b. Eevating iquid Every 1 m ift reduces pressure differentia by approximatey 0,1 bar, when the discharge is ony iquid. Specia Considerations Drain traps are avaiabe for services other than those found on standard compressed air systems. High Pressure Spring-oaded mechanisms aow foat type drain traps to operate on pressures above 200 bar. Fuids Other Than Water Different fuids, such as ois and iquid, can be compensated for with speciay weighted foats or ower operating pressure ratings. Fuids with specific gravities down to 0,4 wi work with foat type drain traps. Materias of Construction Service requirements for stainess stee or other corrosionresistant materias can be met by foat and inverted bucket type drain traps. NACE Sour Gas Service Specia materias and construction are required for hydrogen sufide service.

179 How to Drain Air Distribution Systems Air distribution systems make up the vita ink between compressors and the vast amount of air-utiizing equipment. They represent the method by which air is actuay transported to a parts of the pant to perform specific functions. The three primary components of air distribution systems are air mains, air branch ines, and air distribution manifods. They each fi certain requirements of the system, and together with separators and traps, contribute to efficient air utiization. Common to a air distribution systems is the need for drip egs at various intervas. These drip egs are provided to: Air mains are one of the most common appications for drain traps. These ines need to be kept free of iquid to keep the suppied equipment operating propery. Inadequatey trapped air mains often resut in water hammer and sugs of iquid, which can damage contro vaves and other equipment. There is aso a freeze potentia wherever water is aowed to accumuate. In areas where air is moving sowy, the accumuation of water can effectivey reduce the pipe size, thereby increasing the pressure drop and wasting energy. 1. Let iquid escape by gravity from the fast-moving air. 2. Store the iquid unti the pressure differentia can discharge it through the drain trap. 3. Serve as dirt pockets for the inevitabe dirt and grit that wi accumuate in the distribution system.

180 How to Drain Air Distribution Systems Seection of Drain Traps and Safety Factor for Air Mains Traps shoud be seected to discharge a voume of iquid normay produced when the system is up and running. Liquid oads can be estimated if actua air voume fow is not known. If cod temperatures are possibe, the dew point at suppy pressure must be known. Once this maximum is determined, the safety factor used to size the trap wi be ony 10% of the tota potentia iquid oad. Ten percent of the tota is used because most of the iquid has been removed in the aftercooer and receiver. The drain trap must hande ony the sma remaining amount of 10% of the tota possibe oad.

Where there are no natura drainage points, drip egs and drain traps shoud sti be provided. These shoud normay be instaed at intervas of about 150 m. Guideines for Draining Liquids LD-441

181 How to Drain Air Distribution Systems Branch Lines Branch ines are takeoffs of the air main suppying specific areas of air-utiizing equipment. Branch ines must aways be taken from the top of the air main. The entire system must be designed and hooked up to prevent accumuation of iquid at any point. If a specific process area requires it, an air dryer wi be instaed on the branch ine. Trap Seection and Safety Factor for Branches The formua for computing iquid oad in branch ines is the same as that used for air mains. Branch ines aso have a recommended safety factor of 10% of tota air oad. Drip egs must be instaed ahead of risers and at the end of branch ines, especiay when branch ine runouts exceed 15 m. There are usuay severa branches off the air main, and in many cases they experience a high iquid oad when they run against cod outside was. This cooing causes more moisture to condense in the branch ine than woud be seen in the air main. Distribution Manifods A distribution manifod is a termina for a branch ine from which severa air users are taken off. They are particuary common in manufacturing faciities for pneumatic too hookups or takeoffs to cyinder actuators. Like branch ines, it is common for distribution manifods to be instaed against coo was where ow temperatures cause condensation and the accumuation of iquid. Since the air distribution manifod is usuay one pipe size arger than the branch ine, it is common for air veocity to drop when coming from the branch ine. With this decrease in veocity, often combined with ower ambient temperatures, it is common for a iquid to accumuate in the distribution manifod. For this reason, the use of fiter-drainer combinations or separate drain traps is recommended. Trapping the iquid in the distribution manifod is important to protect the reguators on air-using equipment and orifices in air-using instruments. This is a ocation where manua vaves are commony misused due to their accessibiity. To drain the iquid and keep it from fouing an instrument or pneumatic too, manua vaves wi often be cracked to atmosphere. When they are eft this way, the resut is a arge air oss due to the unrestricted free bow of air to atmosphere. Trap Seection and Safety Factor for Distribution Manifods Normay the smaest drain trap is practica for distribution manifods up to manifod diameters of 2''. Above 2'', the distribution manifod shoud be considered a branch, and then the sizing procedure from the Air Main section woud appy. Distribution manifods are often equipped with fiters and reguators. Reguators may aso be found at the termination before the air-using device.

182 How to Drain Air Distribution Systems Instaation The ABCs of trap instaation must be foowed: A for accessibe, B for beow the point being drained, and C for cose to the point being drained. If the discharge point for this drain trap is some distance away from the drain point, the discharge ine from the trap shoud be run out not the inet to the trap. When instaing traps on the drain connection of fiters, particuar care shoud be taken to the connection size. Normay outet connections on fiters are 1/4'' in size or ess. This connection size is normay not arge enough to aow anything but sugs of iquid to fow into the trap housing. If a foat trap is utiized, it shoud be either back vented or the connection size must be increased to 3/4'' minimum. For additiona instaation recommendations, see pages LD-478 and LD-479.

183 How to Drain Intercooers, Aftercooers and Aftercooer Separator Combinations Aftercooer An aftercooer serves as the primary means of moisture remova on industria air systems. It increases the efficiency of air distribution by reducing pressure drop created when air fows through the system. It does this by using cooing water to reduce the specific voume of the air which, in turn, aows the air to fow through the system with ess pressure drop. Aftercooers are found on most industria compressors over 7,5 kw in size. In addition to removing the heat of compression, aftercooers aso remove approximatey two-thirds of the iquid found in the air, and hep in the remova and knock-down of oi carryover from the compressor. Intercooer Seect the proper trap for: 1. Entering water temperature into the intercooer. 2. Airfow rate through the intercooer. 3. Intermediate pressure at which the intercooer is operated. Use Chart LD on page LD-443, Water Condensed From Compressed Air to determine the grams of water condensed per m³. Then mutipy by the compressor rating (1 700 m³/h) and divide by 1000 to get the water fow in kg/h. Then use a safety factor of 2:1. Intercooer Compressor intercooers are designed to increase the efficiency of compression by reducing the temperature and specific voume of air between stages of compression. This aows the compressor to do more work at a ower temperature than woud normay occur. Because some condensing wi occur in the intercooer, a drain trap is required to protect compressor parts. If iquid were to carry over from the intercooer, it coud aso carry dirt or scae into the compressor and/or aso cause corrosion within the compressor, both of which are undesirabe for efficient compressor operation. If sugs of iquid were to pass from the intercooer into the compressor, it woud make the compressor operation erratic. Efficient trapping is required at this point to deiver dry air to the next stage of the compressor. An intercooer is typicay a she and tube heat exchanger. Liquid condensate fow out of the heat exchanger is usuay irreguar, causing sugs to accumuate and pass into the drain trap. Because of this, a drip eg is required on the intercooer, and fu size outet piping from the intercooer must be used into a dirt pocket. The drip eg aows the sug of condensate to be handed by the drain trap and handes some sma backup whie the drain trap is discharging the iquid. Guideines for Draining Liquids The intercooer may aso experience oi carryover if the compressor is not of the oi-ess or seaed type. As air enters the intercooer, it carries a mist or tiny dropets of oi aong with it. Because the air is at a reativey high temperature, this oi is fairy thin. Then, as the intercooer coos the air and oi, the oi may thicken. The drain trap must be abe to discharge this oi before it thickens and negativey affects the drain trap and intercooer operation. Trap seection is very important in this type of appication where a water and oi mix must be handed by the trap and the oi must be discharged first. Since the aftercooer removes approximatey two-thirds of the tota moisture oad, traps here wi normay be much arger than those found on the rest of the system.

184 How to Drain Intercooers, Aftercooers and Aftercooer Separator Combinations When seecting the type of trap, consider the faiure mode and the abiity of the trap to respond to sugs of iquid. In most cases, an open faiure mode wi be desirabe as it is vita to protect the compressor from sugs of iquid. A quick response to sugs is important so there is no deay between the time the iquid accumuates and the trap discharges the iquid. Aftercooer When the aftercooer condensing rate is not known, there are two typica methods for cacuating condensate oad. The first method is to cacuate tota airfow through the system. Then using Chart LD on page LD-443, tited Water Condensed From Compressed Air determine grams of water condensed per m³. Mutipy this by the compressor rating (1 700 m³/h) and divide by 1000 for required trap capacity in kg per hour (the entering maximum incoming summertime temperature and reative humidity must be known to use this chart). This oad is then mutipied by 2 to determine required trap capacity. The second method of cacuating trap capacity is to ook at maximum aowabe fow rate through the aftercooer. Use the Water Condensed From Compressed Air chart on page LD-443 in the same manner as described in Method 1. Athough this method wi normay yied a arger trap size, it aows for the addition of another compressor or the interconnection of severa compressors to the system in the event of unpanned by-passes. In the second method, it s important to estimate the average water temperature within the aftercooer as cosey as possibe. Not a air actuay comes in contact with the water tubes; therefore, the air is not uniformy cooed to the water temperature. If actua eaving air temperature is known, this is by far the most accurate figure to use. A propery sized aftercooer wi normay coo compressed air down to within 10 C ower than entering air temperature. Instaation When instaing drain traps on aftercooers or aftercooer separator combinations, the ABCs of trap instaation shoud be foowed: Accessibe for maintenance and repair. Beow the point being drained. Cose to the drip point as possibe. Be sure to foow manufacturer s instructions on trap instaation. Most aftercooers are equipped with a separate separator. However, if a separator is not furnished, the aftercooer must be trapped individuay. In the case of the aftercooer/separator combination, ony the separator normay requires a trap. See Fig. LD or LD But again, it is important to foow manufacturer s instructions. For additiona instaation recommendations, see pages LD-478 and LD-479.

185 How to Drain Separators, Separator Fiter Combinations Separators serve an important function within the compressed air system. Separators may aso be known as knockout pots, knockout drums or demisters. Their function is to remove iquid that may be moving at a high speed from the fowing air, and they normay perform this function in a two-step process. 1. Separators increase the fow area and voume of the gas, thereby reducing its veocity. Air within the system may fow at veocities exceeding 45 m/s. At this veocity any iquid wi be entrained as dropets and wi not be fowing aong the bottom of the pipe. To remove these iquid dropets, it is necessary to reduce the veocity of the gas; otherwise, the dropets accumuate and again become entrained with the fowing gas. 2. The second step is to change direction and impinge the iquid. As the veocity of the gas is reduced, the veocity of the fast-moving dropets can be reduced even further by causing the air to take either 90-degree turns or to centrifugay fow within a chamber. Both of these methods serve to sing the dropets up against baffes, pates or the wa of the separator. Because the dropets have a reativey high mass and are incompressibe, their veocity wi drop dramaticay. At this point, gravity wi take over, causing the drops to accumuate and fow into the bottom of the separator. Liquid wi often fa in sheets down the wa of the separator and coect at the outet piping in sugs. The immediate drainage of the sugs is important since the separator is normay a fina opportunity to protect an airusing device downstream. Locations Separators are normay ocated on the eaving side of aftercooers and before the compressed air receiver. They are often integra with fiters ocated before sensitive air-using equipment or as part of the fiter on a distribution manifod. In this case there may be a combination fiter, oier, reguator and separator drainage point for iquids to accumuate. Trap Seection and Safety Factor If the separator is part of an aftercooer combination instaed between the compressor and the receiver, you shoud refer to the section on Aftercooers and Aftercooer Separators for trap seection. Trap seection is fairy critica, especiay on equipment with arger than 1" air ines feeding it, since sug formation can wash scae into the air-using equipment and become a serious dirt probem. Therefore, on arger than 1" separators, the fow shoud be cacuated by totaing the air consumption of the devices downstream and using Chart LD-443-1, Water Condensed From Compressed Air on page LD-443. Use the fu water oad expected and the safety factor of 3:1 to figure trap capacity. If iquid is aowed to accumuate for any amount of time, it may undermine the entire purpose and function of the separator. Therefore, if the separator does not do its job efficienty, it can actuay become a reservoir that accumuates condensate and forms sugs to be transmitted down the air ine and into the device being protected. In this case, the use of a separator may be worse than no protection at a. Guideines for Draining Liquids Tabe LD Recommendation Chart (See chart on LD-429 for Feature Code references.)

186 How to Drain Separators, Separator Fiter Combinations To determine proper trap capacity for separators with a pipe size of ess than 1", the fow can be estimated by using Chart LD-443-1, Water Condensed From Compressed Air on page LD-443, and then cacuating 20% of fu oad. The safety factor for both seection procedures is 3:1 since separators must respond to surges of iquid from the inet. In this case, the trap must hande far more iquid than woud be experienced under norma operation. Instaation When instaing ba foat type traps on separators 1" and above, it s important to back vent the trap (refer to the section on how to hook up ba foats for the purpose and function of back vent ines, page LD-478). A other types of drainers shoud be couped as cosey as possibe to the drain eg. The drain eg shoud be the same size as the drain connection on the separator and extend 150 mm beow the separator with another 150 mm aowed for a dirt pocket. The trap is then tee d off this ine (see Figs. LD and LD-447-2). This piping is crucia because, as noted above, if the separator does not receive fu drainage, it can be worse than no separator at a. For this reason, the ABCs are critica: Accessibe for inspection and maintenance. Beow the equipment being drained. Cose to the drain point. The ine size eading from the drip eg to the inet of the unit shoud be kept the same size as the trap inet for good drainage into the trap. Again, when sugs are being handed it s important that the trap begin draining immediatey. Back vents on foat type traps shoud be a minimum of 1/2" in pipe size with 3/4" preferred. Any vaves used in this back-vent piping shoud be fu ported to aow free gas fow out of and iquid fow into the drain trap. For additiona instaation recommendations, see pages LD-478 and LD-479.

187 How to Drain Receivers Receivers perform the vita function of storing air for the system. The receiver dampens pressure fuctuations in the system and provides a very short storage time in the event of compressor faiure. It aso functions as a iquid knockout drum to prevent entrained iquid (which may carry over) from entering the compressed air dryer or the air mains. The receiver shoud be sized to provide enough storage time for an ordery shutdown, particuary in the case of instrumentation air systems. Receiver voume is what provides the amount of air required for storage periods. The receiver shoud be ocated cose to the compressor. Faout of iquid is norma due to ow veocity within the receiver. Veocity is at the owest point it wi reach in any other part of the operating system. The air has a high dwe time within the receiver and is more ikey to coo to ambient. This cooing of the air is what causes moisture to condense. The receiver is equipped with a drain port at the bottom to aow iquids to fow to drain traps. In many cases, because receivers are so arge and ocated adjacent to the compressor, they are instaed cose to the foor. When this happens, the drain point is reativey inaccessibe, making trap piping difficut and gravity fow into the trap often impossibe. To avoid this, the receiver shoud be ocated on a sma concrete pad, which wi faciitate efficient drain trap instaation and operation. For severa reasons, it s good to keep the receiver drained. When receiver voume is ost, the dampening of the compressed air pressure is reduced and the storage time between compressor faiure and system shutdown is greaty reduced. Corrosion within the receiver can aso take pace when iquid is aowed to accumuate. Manua vaves are commony used to drain receivers since they are typicay instaed cose to the foor. The resuting oss of receiver voume is sedom noticed in the day-to-day operation of the system. However, with any manua system, the vave can be forgotten and not opened. Then, when the weather changes from a reativey dry, ow moisture oad to a warm, high moisture oad, the receiver wi ose voume and the dampening effect and accumuator effect are decreased. The compressor can short cyce under these conditions, increasing the wear and tear on the compressor. In addition, the ony reminder to open the manua vave is when carryover occurs. In this case, an air dryer can be damaged, iquid can be introduced into the air mains and surge through the system, causing scae to be washed into the system, water hammer and/or freeze damage. Trap Seection and Safety Factor To seect the proper trap for the receiver, it is necessary to cacuate tota system oad using Chart LD-443-1, Water Condensed From Compressed Air, on page LD-443. Once this tota potentia oad is known, it wi be mutipied by the foowing factors: With an aftercooer, mutipy the oad by 50%, with an aftercooer separator combination, mutipy the tota oad by 40%, and if no aftercooer is present, mutipy the tota oad by 70%. Once this oad is known, a safety factor of 2:1 is appied.

188 How to Drain Receivers Instaation When a foat type drain trap is used with a receiver, the eve wi run at about the inet connection on the trap. Therefore, it is important to ocate the trap as cose to the foor as feasibe and with no dips in the piping. See Figs. LD thru LD If there is a piping dip with a foat type unit and the vent connection is not back vented, the unit wi fai to operate. In the case of a back-vented unit, the dip in the piping wi be fooded at a times. An inverted bucket trap can be instaed above foor eve since it wi operate above the drain point. An interna check vave, tube and couping shoud be instaed to prevent the iquid sea from fowing backward on system shutdown. A snap action type foat unit shoud be used when any amount of grit is expected in the system. In this case, the spring ife can be extended by moving the drain trap sighty upward to aow iquid to accumuate both within the receiver and within the trap body between trap cyces.

189 How to Drain Dryers The function of dryers is to eiminate iquid in appications where freezing or any moisture accumuation can cause serious probems with the air-consuming equipment. Dryers shoud aways be instaed on instrument quaity air systems. Two basic dryer types are dessicant and refrigerated. In the dessicant type, the dessicant chemica absorbs the iquid by chemicay bonding with the water moecues. Dessicant dryers can achieve very ow dew points and are often instaed with a pre-dryer of the refrigerant type. Refrigerant dryers work the same as aftercooers by circuating cod fuid, causing the moisture to condense. However, their abiity to reach ow dew points is imited by the temperature at which frost wi form on the heat exchanger tubing (greaty reducing heat transfer). This eads to a discussion of air dew point. Dew point is the temperature at which moisture wi condense out from the air due to its reative humidity increasing above 100%; see Chart LD When this happens, the moisture condenses out and can be drained to a drain trap. Dew point is aso important when considering air that has eft the dryer, because if the air is ever exposed to temperatures beow its dew point, moisture wi form. Therefore, when appying air dryers, it is important to consider two features of compressed air usage that wi impact dryer seection. 1. When air is compressed, the dew point is increased. Aso, the dew point under pressurized conditions must be known. For exampe, even though a 4 C dew point is achieved at atmospheric conditions, this becomes a dew point of about 12 C once the air has been compressed to 7 bar. In outdoor systems, when the temperature drops beow 12 C, condensing and freezing of that moisture wi resut. 2. When compressed air is expanded through instruments or air toos, its voume increases, pressure decreases and a temperature drop is usuay experienced. If the temperature drops beow the dew point of the air, undesirabe moisture forms in the equipment. The air woud never be subjected to that temperature under any conditions other than when expanding.

190 How to Drain Dryers Drain traps are usuay required on refrigerated type dryers ony. Here the refrigerant chis air and creates moisture that the drain trap can discharge. In the case of the dessicant type air dryer, the chemica grabs the moisture and bonds chemicay with the water moecues, and no iquid accumuates. These bonded water moecues are then usuay driven off in a regeneration cyce the dryer must periodicay undergo. Trap Seection and Safety Factor In most cases, the dryer manufacturer wi rate the dryer for a given moisture remova rate. The safety factor shoud sti be appied to this oad, however. If the manufacturer s ratings are not known, then it s necessary to cacuate the moisture content of the air at aftercooer conditions and the moisture content at ambient conditions. Using the ower moisture content between these two, compare that figure to the moisture content at the dew point of the air eaving the dryer. The difference in these moisture contents is then mutipied by the airfow through the dryer to determine the moisture oad. The safety factor appied to the oad is 2:1 since iquid shoud be drained immediatey from the dryer and the iquid tends to fow into the drain trap in sugs. Instaation The dryer shoud come with a drain port of a given pipe size sufficient to hande the iquid coming out of the dryer. In this pipe size, a drain eg shoud be piped up 150 mm beow the dryer with another 150 mm beow that as a dirt pocket. Teeing off this ine and into the trap with the same inet size as the trap wi aow for gravity drainage into the trap. Again, the ABCs of trap instaation shoud be foowed: Accessibe. Beow the point being drained. Cose to the drain eg as possibe. If the trap is too cose to the foor to aow the use of a ba foat trap, an inverted bucket trap shoud be considered.

The proven capabiities of these components, aong with voume production economies, enabe us to offer you exceptionay high quaity at attractive prices. You can choose the smaest and east costy mode that wi meet your requirements with confidence. Seection Procedure for Draining Liquid From Gas 1. Mutipy the actua peak iquid oad (kg/h) by a safety factor of at east 1,5 or 2. See paragraph headed Safety Factors. 2. From Orifice Capacity Chart LD-453-1, find the orifice size that wi deiver the required cod water capacity at the maximum operating pressure. If a ight iquid is to be drained, convert ight iquid capacity in kg per hour to water capacity using factors in Tabe LD Then find orifice size from Chart LD From the Orifice Size Operating Pressure tabes on the product mode pages, find the drain trap(s) capabe of opening the required orifice size at a specific pressure (and specific gravity if other than cod water specific gravity 1,0). Note: If specific gravity fas between those shown in the tabes, use next ower. Exampe: If specific gravity is 0,73, use 0,70 gravity data. Safety Factors Safety factor is the ratio between actua continuous discharge capacity of the drain trap and the amount of iquid to be discharged during any given period. Chart LD shows the maximum continuous rate of cod water discharge of the drain trap. However, you must provide capacity for peak oads and, possiby, ower-than-norma pressures. A safety factor of 1,5 or 2 is generay adequate if appied to the peak oad and the minimum pressure at which it occurs. If the oad discharge to the trap is sporadic, a higher safety factor may be required. Contact your Armstrong Representative for detais. Seection Exampes EXAMPLE No. 1: Find a drain trap to drain 500 kg of water per hour from air at 33 bar pressure differentia.

In Capacity Chart LD-453-1, the kg/h capacity ine intersects the 33 bar pressure ine directy beow the #38 dri orifice curve. This orifice is avaiabe in the Modes 1-LD or 11-LD drain trap, but for much ower pressures. Moving to the 32-LD, a #38 orifice is good to 34 bar. This is the trap/orifice combination to use. Tabe LD-464-1, page LD-464, shows the Mode 32-LD drain trap with #38 orifice wi operate at pressures up to 34 bar and, therefore, is suitabe for the job. Further checking shows the Mode 2313 HLS drain trap with a 7/64" orifice coud aso hande the job, but it is designed particuary for ow gravity iquids and is more costy than the Mode 32-LD, so the Mode 32-LD is a better choice. EXAMPLE No. 2: Find a drain trap to drain kg/h (safety factor incuded) of 0,80 specific gravity iquid from gas at 28 bar pressure differentia. Since Capacity Chart LD is based on water capacity, the known ight iquid capacity requirement must be converted to its equivaent water capacity with the factor given in Tabe LD-452-1: x 1,12 = = water capacity required for using Chart LD Chart LD shows that kg/h and 28 bar cas for a 7/32" orifice. Entering the 0,80 specific gravity coumn of Tabe LD-450-1, page LD-450, shows that a Mode 36-LD forged stee drain trap wi open a 7/32" orifice at pressures up to 49 bar. As a matter of fact, this drain trap wi open a 1/4" orifice at 35 bar and woud be the one to use. Note: Whie drain traps are sized on the basis of pressure differentia, stee must be used whenever gauge pressure in the drain trap exceeds 17 bar. Where Not to Use Foat type drain traps are not recommended where heavy oi, sudge or considerabe dirt are encountered in ines. Dirt can prevent the vave from seating tighty, and cod oi can prevent foat traps from opening. Where these conditions exist, Armstrong inverted bucket BVSW traps shoud be used. How to Order Drain Traps Specify: Drain trap size by number Orifice size Pipe connections size and type Maximum operating pressure If the correct drain trap cannot be determined, te us capacity required, maximum pressure, and SPECIFIC GRAVITY of iquid.

192 How to Seect and Size Armstrong Drain Traps For Draining Water From a Light Liquid Armstrong dua gravity drain traps for draining water from a ight iquid are described on pages LD-474 and LD-475. A modes shown are identica to corresponding modes of traps used to drain iquid from a gas except that foat weights are modified to make them suitabe for draining water from a ight iquid. Dua gravity drain trap* seection requires that you know the peak heavy iquid oad, maximum operating pressure, and specific gravity of the ight iquid. With this information you can determine the orifice size required from Chart LD and find the specific drain trap that wi meet your conditions from the pressure tabes on the dua gravity pages. Seection Procedure for Draining Water from a Light Liquid 1. Assume a required safety factor of 2:1. Mutipy the peak oad in kg per hour by 2. (See paragraph on Safety Factors. ) 2. From Capacity Chart LD-453-1, find the intersection of actua oad times safety factor and the minimum operating pressure differentia. Foow the pressure ine immediatey above this point to intersect the next higher orifice capacity curve. Then foow this curve downward and to the eft to get the orifice size. 3. Inspect the tabes on pages LD-474 and LD-475 to find the smaest trap that can open the predetermined orifice size at the maximum operating pressure differentia. Do not oversize dua gravity drain traps. Oversizing wi cause excessive fuctuation of the interface between the two iquids. Note: Whie drain traps are sized on the basis of operating pressure differentia, forged stee must be used when tota pressure in the drain trap exceeds 17 bar. How to Order Dua Gravity Drain Traps Specify: Drain trap size by number Orifice size Pipe connections size and type Specific gravity of ight iquid Weight of water discharge per hour Maximum operating pressure If you are not sure of the drain trap size to use, then specify: Specific gravity of ight iquid Capacity in kg of water per hour with safety factor incuded Working pressure maximum and minimum Chart LD Cacuated Cod Water Capacity of Armstrong Drain Trap Orifices at Various Pressures Actua capacity aso depends on trap configuration, piping and fow to trap.

200 Pressure Reducing Vaves PRV Types Steam, iquids and gases usuay fow at high pressures to the points of fina use. At these points, a pressure reducing vave owers the pressure for safety and efficiency and to match the requirements of the appication. There are two types of pressure reducing vaves offered by Armstrong: Direct Acting. The simpest of PRVs, the direct acting type operates with convouted beows. Since it is sef-contained, it does not need an externa sensing ine downstream to operate. It is the smaest and most economica of the two types and is designed for ow to moderate fows. Accuracy of direct acting PRVs is typicay ±10% of the downstream set point. Externay Pioted. This type of PRV incorporates two vaves - a piot and a main vave - in one unit. The piot vave has a design simiar to the direct acting vave. The discharge from the piot vave acts on a set of doube diaphragms, which contros through a piston the opening of the main vave. This high diaphragm area can open a arger main vave, aowing a greater capacity per ine size than the direct acting reguators. In addition, the diaphragms are more sensitive to pressure changes, and that means accuracy of ±1%. This greater accuracy is aso due to the ocation of the sensing ine outside of the vave, where there is ess turbuence. This vave aso offers the fexibiity to use different types of piot vaves: pressure, temperature, air oaded, soenoid or combinations. Pressure and Temperature Contros PTC-266

208 Externay Pioted For Steam Service This type of PRV incorporates two vaves - a piot and a main vave - in one unit. The piot vave has a design simiar to the direct acting vave. The discharge from the piot vave acts on a set of doube diaphragms, which contros through a piston the opening of the main vave. This increased diaphragm area can open a arger main vave, aowing a greater capacity per ine size than the internay pioted piston-operated vave. In addition, the diaphragms are more sensitive to pressure changes, which resuts in accuracy of ±1%. This greater accuracy is due aso to the positioning of the sensing ine downstream, where there is ess turbuence. This vave aso offers the fexibiity to use different types of piot vaves: pressure, temperature, air oaded, soenoid or combination. Pressure and Temperature Contros Interchangeabe springs - regardess of vave size - means more fexibiity in appications. Encosed spring chamber eiminates dirt fouing. Avaiabe in both integra and remote mounted piot. Integra strainer protects the piot vave from faiure due to dirt. Dua stainess stee diaphragms provide corrosion resistance. Easiy removabe copper tubing permits troubeshooting whie vave is in-ine. A cast mating parts are mae and femae to reduce the chance of eaks at gasket surfaces and assure proper aignment. Easy access to main vave for quick inspection or maintenance by removing main vave spring and screen and ifting vave from stem. No specia toos needed. Ductie iron body provides a wider range of appications than cast iron and offers a ess costy option to cast stee. Design eiminates copper tubing from passing around the bottom diaphragm housing, minimizing chance of damage during shipping or instaation. PTC-274

226 OBK-2000 Pressure and Temperature Contros Pneumatic Temperature Piot A compact pneumatic temperature piot with broad temperature ranges, the OBK-2000 can be remotey ocated away from the reguator vave, an advantage not avaiabe with a conventiona capiary system. Typica appications incude instantaneous or storage tank water heaters, air make-up units and manufacturing process operations such as parts washing, die casting and pastic moding. Capabe of reverse or direct-acting operation, the OBK-2000 features a simpe design with fewer moving parts for troube free operation. Other features incude suppy and contro pressure gauges, a rugged cast brass housing, and precise and rapid response to temperature changes. Brass, stainess stee bubs and separate wes are avaiabe. OBK-2000 Reverse-Acting Operation - For Heating During operation, a temperature change in the medium being controed creates a change in the ength of the sensitivity tube. An increase in temperature engthens the sensitivity tube (1) and moves the invar rod (2) from the ever (3). The ever pivots at point B and is moved so the exhaust vave (4) is opened by the spring at (D). This ever action decreases the suppy air at point (S) in the contro ine at point (R) and coses the reguator vave. A decrease in temperature shortens the sensitivity tube at point (1) and moves the invar rod against the ever point (3). The ever at this point moves against the spring at point (D) to cose the exhaust vave at point (4). This ever action increases the pressure in the contro ine at point (R) and opens the vave. The sensitivity adjustment screw at point (6) reguates the rate of fow of the suppy air to the controer to a change in temperature. Turning the screw cockwise increases the sensitivity by reducing the fow and increasing the response time. Turning the screw countercockwise decreases the sensitivity by increasing fow and reducing the response time. Vave coses on air faiure, making it fai-safe.

228 Contro Vave Erratic contro. Costy maintenance. And a vave that hunts because it can t find its set point. They re famiiar contro vave probems. And the a-too-famiiar soution? Overki. Pay more than you shoud for a vave that does more than it needs to. Too often, matching a vave to an appication is a matter of taking what you can get to do the job an oversized actuator, for instance. Instead of getting what you need. Inefficient? Of course, but unti now it s aso been unavoidabe. Accuracy and Contro That s Not Overpriced or Overki The Armstrong contro vave gives you exacty what you need to appy the right vave to an appication: fexibiity. It fis the void eft by expensive industria vaves that can t deiver the contro you must have. Designed for steam and hot water service, the Armstrong vave is ideay suited to non-freezing appications in the 1/2" to 1 1/2" range: reheat cois, pipe cois, food dryers, meat smokers, corrugators, aundry and food processing equipment to name a few. The standard Armstrong contro vave is reverse acting with a spring return. It uses air to open and fais cosed (air to cose avaiabe consut factory). The vave meets the vast majority of typica contro vave appications without sacrificing rangeabiity (minimum controabe fow). Note: For water service, the vave must be piped in reverse. Pressure and Temperature Contros Years of successfu performance in rigorous steam contro appications ensures reiabiity on the job. Externay adjustabe start point (1/2" & 3/4" size ony) is standard on pneumatic operator saves operator time and effort. Repairs quicky without dismanting the piping. Dacron-reinforced siicone diaphragm is fatigue and temperature resistant. A trim parts are stainess stee or brass. That means ong ife and reiabiity no corrosion to damage the vave or affect performance. Standard reverse-acting design with spring return uses air to open so it fais cosed. (Directacting avaiabe as an option.) Unique paraboic pug provides accurate moduation of fow over compete vave stroke. Suitabe for a wide range of appications in the 1/2" to 1 1/2" pipe size range. PTC-294

229 Contro Vave Seection Accuracy by Design Not by Accident The secret of accurate contro is making sure a vave s contro characteristics match the appication. When they do, the vave contros accuratey (without hunting) and performs reiaby. When there s no match, the vave simpy cannot do what the appication demands. Armstrong uses a modified paraboic pug to hande exceptionay ow output. The modification of true inear characteristics provides more precise contro when capacity requirements are very ow and the vave is just cracked off the seat. Notice in Figure that at point A on the curve more than haf the vave stroke is devoted to 40% of the unit s capacity. At point B, 1/4 of the stroke is devoted to ony 10% of capacity. At point C, 10% of the stroke covers ess than 5% of the unit s capacity. How ow can the unit contro? Tabe on page 296 tabuates this function, caed rangeabiity. Rangeabiity is the ratio between the maximum controabe fow and the minimum controabe fow through the vave. The higher the rangeabiity of a vave, the more accuratey it can contro fow when ow output is required. If rangeabiity is too ow, the vave wi hunt excessivey when ow output is required. To cacuate minimum fow, simpy mutipy Cv by the percentages shown in the tabe. For exampe, a 5/16" orifice in an ACV-02 has a Cv of 2,5. The owest output that can be controed is 2% of maximum fow.

240 Python Series Contro Vaves Vave Sizing To determine the size of vave you need, cacuate the required C v vaue for your appication. Once you have cacuated the required C v, refer to the vave C v charts on page PTC-301 to determine the size and trim of vave. Gobe stye contro vaves have the best contro in the midrange of the vave's capacity. It is best to pick a vave so the cacuated C v is between 15% and 85% of the vave opening, see page PTC-307. See the formuas beow for steam and water appications. Consut factory for other types of fuids. Soution: Vave Seection: Seect the correct formua needed to cacuate C v. We need to use the critica fow formua since P2 < P1/2. W = 10.CV.P1 <=> CV = 50 Refer to the C v charts on Page 4. Seect a 2-1/2" Muti-hoe cage guided with 2-1/2" Trim. Top bush guided woud work as we, but muti-hoe cage was chosen to hep with noise attenuation. Pressure and Temperature Contros For Saturated Steam Service When P 2 > W = 20 x C v x ΔP x P 2 2 When P 2 < W = 10 x C v x P 2 1 For Liquid Service Q = P 1 P 1 0,86 x C v x ΔP G C v = Vave fow coefficient G = Specific gravity in kg/dm³ Q = Maximum fow capacity of iquid in Nm³/h P 1 = Inet pressure in bar(a) P 2 = Outet pressure in bar(a) ΔP = Pressure drop (P 1 - P 2 ) in bar W = Maximum fow capacity of steam in kg/h Actuator Sizing: To determine the required actuator, you need to determine the differentia pressure (shut off pressure). The shut off pressure for a pressure reduction appication is the pressure difference between P1 and P2. The shut off pressure for a temperature contro appication is the P1 pressure. Once you have cacuated your shut off pressure, seect the actuator mode and spring setting range that exceeds your cacuated shutoff pressure with the trim size previousy seected. Seect reverse acting for air to open (fai cose) appications or direct acting for air to cose (fai open) appications. Make sure the required air pressure is avaiabe for the spring range seected. Sizing Exampe 1: Fuid : Saturated Steam P1 = 10 bar P2 = 2 bar Fow: 6000 kg/hr Actuator: Air to open (Fai Cose) Actuator Seection: Determine your shutoff pressure (DP). DP = 10-2 = 8 bar Refer to chart (muti-hoe cage guided) and go to the 2-1/2" trim size coumn. Foow the coumn unti you get to a pressure greater than 8 bar, then foow the row horizontay to determine you need a Mode M-22 with the 0,2-1 bar spring range. Compete vave seection is 1100 series, 2-1/2" PN40 Fange with 2-1/2" Muti-hoe cage trim and M-22 actuator with 0,2-1 bar spring range. Sizing Exampe 2: Fuid : Saturated Steam P1 = 9 bar Fow: 700 kg/hr Actuator: Air to open (Fai Cose) Soution: Since this is a temperature contro appication and we do not know the P2 pressure, we wi size the vave with a 30% pressure drop. We need to use the subcritica fow formua. W = 20.CV. ΔP.P2 700 = 20.CV. 2,7.6,3 CV = 8,5 Refer to the C v charts on Page 4. Seect a 1" Contoured top guided with fu port trim. The 1" is chosen over the 3/4" because the vave wi contro best between 15% - 85% of maximum vave capacity. The 3/4" vave woud be operating at 98% of vave capacity. Actuator Seection: For temperature contro appications, the shut off pressure is the P1 pressure. Refer to chart 6-1 (Contoured Top Guided) and go to the 1" trim size coumn. Foow the coumn unti you get to a pressure greater than 9 bar, then foow the row horizontay to determine you need a Mode M-00 with a 0,4-1,2 bar spring range. Compete vave seection is 1100 series 1" BSPT with 1" contoured top guided trim and M-00 actuator with 0,4-1,2 barg spring range. PTC-306

241 Python Series Contro Vaves Determine the percentage of vave open at any cacuated C v You must first sove for a required C v with one of the formuas on page PTC-306. Using sizing exampe 2, we cacuated a C v of 8,5 and we chose a 1" contoured top guided vave with a fu 1" trim with a maximum C v of 13. Step 1: Locate seected vave trim size in the far right-hand coumn. The maximum Cv for this trim can be found by moving two coumns to the eft. Step 2: Locate the cacuated Cv (fow coefficient) on the far eft side. Step 3: Foow cacuated Cv to the right unti it intersects with the curve associated with the trim size found in step 1. Step 4: From the point of intersection, trave verticay to the bottom of the chart. This point indicates the percentage of vave open, at the cacuated Cv. In this case the vave wi operate at 83% of the vaves maximum capacity. The vave has the greatest contro between 15 and 85% of the vave opening. Pressure and Temperature Contros PTC-307

254 The Proof Is in the Piston Steam Tracing Equipment Many of Armstrong s manifods utiize the piston vave because of its years of exceent performance in steam systems a over the word. The proof of Armstrong s ong service ife for manifods is in the piston. A types of vaves pug vaves, gate vaves, piston vaves and even ba vaves have been summoned for duty in steam service. Due to its exceent seaing characteristics in steam service, and because it has no gand packing, the piston vave is frequenty seected for steam systems. Peope who have used it over the past 90 years can testify that eakage to atmosphere is extremey rare, even without any The Piston Vave maintenance. The eastic contact between piston and vave seaing rings provides a perfect tightness, both in-ine and to atmosphere. Steam system vaves, whatever their design, are used to isoate steam and condensate ines or when a fauty steam trap needs to be removed from the ine. This means the vaves stay in the open position for ong periods and are neary aways in contact with the atmosphere. It is not surprising, therefore, that when the vaves need to be cosed, they can often prove difficut to operate. Our experience and the demands from end users for energy efficiency have ed us to a seaing system designed especiay for steam service. Stem Cap Stainess Stee Vave Pug Disc Springs Graphite and Stainess Stee Vave Seaing Rings Lantern Bushing Open Position Cosed Position Dua seaing action. The piston vave is a seatess vave that incudes two graphite and stainess stee vave seaing rings that sea the stem and function as a seat. This combination provides ong-term protection against eaks to the atmosphere and downstream piping. Sef-ceaning action. Stainess stee piston sides without rotating between the two vave seaing rings, preventing dirt from damaging the surfaces. Seaing integrity. Fexibe disc springs automaticay provide eak tightness by exerting pressure, which keeps the upper and ower vave seaing rings compressed at a times. Seaing tightness is ensured by the compression of the seaing rings against the piston and vave body. This combination of disc springs and dua vave sea rings protects against expansion and contraction due to heating and cooing. This ensures dependabe operation, even after years of service. Protected vave stem. The vave stem and seaing surfaces are competey protected from dirt and corrosion by the stem cap, whether in an open or cosed position. In-ine repairabiity. A seaing vave components may be easiy repaced in-ine. Long-term operation. Piston vave design ensures actuation even after many years without operation. STE-188

268 AB-3000 Bimetaic Steam Trap Stainess Stee For Pressures to 22 bar Capacities to kg/h Steam Tracing Equipment Description Armstrong's AB-3000 Bimetaic Steam Trap operates by the effect that rising temperature has on bimetaic eements. It adjusts itsef to changing conditions, as the increasing pressure on the vave is compensated by the curving of the bimetaic eements caused by the increasing temperature. The vave of the AB-3000 is speciay treated (boronization) in order to be more resistant to wiredrawing due to erosive condensate fashing. Armstrong's AB-3000 has a seaed, stainess stee body that is ightweight, compact and highy resistant to corrosion. The AB-3000 is repairabe (body and cap can be unscrewed). It is piped through the Armstrong 360 Universa Connector or Trap Vave Station (TVS). This makes it easy to insta and repace, as the trap can be removed whie the connector remains in-ine. The resut is savings in abor cost and increasing in fexibiity, as other trap types (Inverted Bucket, Thermostatic and Thermodynamic) can be instaed on the same connector. Vave Boronized The probem of wiredrawing of vave and seat materias is we known to users of steam traps and other types of vaves. Wiredrawing is a particuar probem to vaves and seats of bimetaic traps, which rey on bimetaic eements to operate. To sove the probem of wiredrawing, a new thermochemica surface treatment has been deveoped. The basic vave materia is machinabe hardened chrome stee. Atoms of highy resistant materia are thermochemicay diffused into the vave, giving a ayer of protection and a hardness of 1700 HV to the basic materia. Because of this new thermochemica treatment, the surface of the vave is highy resistant to the erosive action of fashing condensate. The faiure rate of Armstrong bimetaic traps due to wearing out of vave and seat materia is greaty reduced.

279 SteamEye -The Ony 24/7, Wireess, Labor-free Steam Trap Monitoring System! SteamEye can monitor any manufacturer's trap and any trap type. Steam Trap Management "It's ike having a man sitting there watching traps a day." That's how a maintenance supervisor at an instaation summed up the benefits of SteamEye. But exacty how does SteamEye do what it does? And how does it use radio waves to signa a rea beginning in steam system optimization? What is radio frequency (RF) steam trap monitoring anyway? Radio frequency monitoring of steam traps gives you an instantaneous insight into trap performance that is the most accurate measure of steam trap status avaiabe. The system consists of a transmitter, a repeater (if necessary), and a receiver. Buiding automation system integration is aso an option. Consut your Armstrong Representative or Armstrong's Appication Engineering Department. SteamEye saves energy and money Whoever first observed "Litte things mean a ot" perhaps had faied steam traps in mind. Show us a steam trap bowing through (osing steam), and we' show you potentia for huge savings in the amounts you spend for energy to generate steam in the first pace. Besides, ess energy consumed means ess waste, fewer emissions and a heathier environment. As you see from the tabe beow, a itte steam eak can truy be the start of something big. A singe trap with an 1/8-inch orifice can squander more than 4,000 per year. Mutipy that by the number of traps represented in a typica 20% faiure rate, and you begin to get the idea. Faied steam traps waste energy and cost you money. Big money. But that was then. Now there's SteamEye. What does an undetected faied steam trap cost? At today's energy prices, steam trap bow-thru can no onger be toerated. Energy ost means doars ost. In addition to energy osses, do not forget the other costs associated with undetected steam trap faiure.

280 SteamEye Proven Technoogy Steam Trap Management The SteamEye System Radio frequency technoogy has been around for decades. Armstrong Internationa has taken this technoogy, combined it with our 100 years of steam trap experience and deveoped a product to accuratey determine the operationa condition of any type, make and mode of steam trap without a abor requirement. Each transmitter is equipped with an eectronic board. This board houses the engineered "thought process" that gives SteamEye its reiabiity and accuracy. The Utrasonic transmitter uses a unique Armstrong designed Waveguide that concentrates the operationa sound of any steam trap to the eectronic board of the transmitter. The "thought process" of the eectronic board "istens" to the trap operation and determines precisey whether a trap is operating normay or is in a bow-thru state. In addition to the bow-thru condition, the transmitter have the abiity to sense when a trap is cod. To eiminate fase readings on moduating steam appications, the Utrasonic moduating transmitter wi check to see if pressure exists before sending a cod aarm. SteamEye How It Works The transmitter sends a radio frequency signa indicating the status of the steam trap back to a Web-enabed receiver. The Web-enabed receiver is connected to your company network running the SteamStar Web-based software. Information regarding a steam trap's operating condition (OK, bow-thru or cod) can be viewed with this software. Because SteamEye and SteamStar are inked through the network, users from various areas in the faciity can see the rea-time trap status. What is the typica range of the RF signa? In appications where the transmitter is ocated within the ine of sight of the receiver, the range is approximatey 400 meters. In faciities where the signa must trave through was or foors, the range varies. The typica range of the signa is approximatey 100 meters. If the receiver is out of the range of a transmitter, devices caed repeaters can be paced between the transmitter and the receiver to "repeat" the signa from one device to the next. A transmitter signa can pass through up to seven repeaters. Since it is difficut to know the range of a transmitter in a faciity, a radio-frequency-signa-strength survey wi determine if repeaters shoud be used and how many wi be required. Typica Pant Layout 400 m 400 m Let's face it: At any given time a percentage of your traps have faied, and you just don't have the manpower to check them frequenty. Besides, the trap you check on Tuesday afternoon may fai Wednesday morning and not be schedued for a recheck for months, even years. You just have to put up with a certain percentage of faiure, right? Wrong. Not any more. That's precisey the point of SteamEye.

281 SteamEye Transmitter Choices The Utrasonic 3700 Series transmitter is used for appications at 2 bar or above. In addition, each series transmitter has two operating designs, constant pressure and on/off. The constant pressure transmitter is used on steam traps where steam is "on" at a times. The on/off transmitter shoud be used in appications where steam pressure is not constant. An exampe of an on/off appication woud be a batch process: steam pressure is required when the process is running, and steam is vaved off when there is no batch being run. The purpose of the on/off transmitter is to eiminate a fase cod signa due to no steam pressure. The on/off transmitter provides a connection aowing the unit to be tied to a pressure or position switch that indicates whether the system is pressurized.

285 Steam System Survey These figures represent a case in which just one trap has bown through typica faiure mode of many steam traps. Compound the figures by the number of potentia faied traps and you can begin to understand the vaue of trap maintenance, both in terms of energy and the extra oad paced on your environmenta ceanup systems. Evauation = Efficiency = Dividend Reiabe evauation of steam trap operation is necessary for traps to work at peak efficiency. Trap testing is a key eement in a compete energy management program, and an essentia ski for protecting your investment. Accuratey evauating steam trap operation can pay dividends in energy conservation, save countess maintenance hours, and reduce unsche dued downtime caused by trap faiure. Steam Trap Management History Industries use approximatey 42% of the tota energy consumed annuay in Europe. Of this, about haf (or 21% of tota European energy consumption) is used to generate steam in more than 54,000 arge industria-sized boiers. Unfortunatey, much of that steam is ost through eaks in the distribution system, incuding piping, vaves and steam traps. Lost steam must be repaced, which can ony be done in a boier that consumes fue. The cost of repacing wasted steam can be enormous in terms of system efficiency, ost production, fue consumption, makeup water treatment cost, and maintenance. These additiona costs must be factored into the bottom ine of every organization. Environmenta Considerations Inadequate trapping on steam mains not ony resuts in economic os ses, it aso creates environmenta concerns as additiona fue is burned to repace ost steam. For exampe, assume the steam-main pressure is 10 barg and the eak size is 5/64" about the thickness of a coin. In this instance, approximatey 12 kg of steam wi be wasted per hour esca - ping from the system or bowing through a trap and into the return ine. Tweve kiograms per hour may not sound significant, but over one year (8,400 hours), that sma eak wi waste the foowing equivaent amounts for fue: 1.9 tons of bituminous coa at a vaue of 679 (coa cost 57/ton) of residua oi at a vaue of 978 (oi cost 0,11 /) 89 m³ of natura gas at a vaue of 1,272 (gas cost 14,30/m³) Puverized bituminous coa in a dry bottom-firing boier wi generate the foowing poutants per year: 330 kg of particuate matter 211 kg of sufur oxides 114 kg of nitrogen oxides 3,3 kg of carbon monoxide kg of tota carbon Steam-Trap Survey To ensure that your steam traps are maximizing the return on your pro duct investment, your first steps shoud be to conduct a steam-trap audit or trap survey, then impement a comprehensive trap-maintenance program. Proper trap maintenance requires someone who knows how each type of trap functions and can determine if each trap is operating as required. Armstrong has the abiity and trained personne to conduct steam system energy audits for any faciities in the word. Our factory-trained technicians have decades of experience and have tested tens of miions of steam traps wordwide. Test and Repace Just the Faied Traps The sooner a trap is identified as an energy waster, the sooner it can be repaced. Since newer testing methods require minima abor, traps can be tested more frequenty and faied traps can quicky be identified. In addition, perfecty good traps that may be misdiagnosed as faied by ess reiabe testing techniques wi no onger be routiney repaced, thus saving the expense of a new trap and reated abor costs. Armstrong continues to ead the industry with innovative testing and tracking toos such as SteamStar, SteamEye and TrapAert. By using SteamEye technoogy, you can better spend your maintenance time repairing ony defective traps and not evauating traps that have been misdiagnosed as faied. In conjunction with SteamStar, the system becomes the premier steam trap management package for maintaining a heathy steam system. Maintaining the Boier Pant Boier pant reiabiity and efficiency depend on the stabiity and success of each component of the steam generation, distribution and condensate return system. Maintaining a boier pant means paying cose attention to components incuding fanges, ebows, vaves, unions and steam traps, since each component has the potentia to waste steam. We can hep with proper system evauations, as we as piping recommendations, repacement-trap sizing and troubeshooting. ST-183

288 Armstrong Steam Traps Steam Traps Pay ess money for energy and more attention to the environment. It s pretty obvious, reay. An efficient steam trap wastes ess energy, which means you burn ess fue and reduce emissions. The resuts are energy savings and a ceaner, heathier environment. By heping companies manage energy, Armstrong steam traps are aso heping protect the word we a share. As a steam trap wears, it oses efficiency and begins to waste energy. But Armstrong inverted bucket traps ast years onger than other traps. They operate more efficienty onger because the inverted bucket is the most reiabe steam trap operating principe known. Ceary, the onger an efficient trap asts, the more it reduces energy wasted, fue burned and poutants reeased into the air. It s an a-around positive situation that ets the environment win, too. Bringing energy down to earth in your faciity coud begin with a renewed focus on your steam system, especiay your steam traps. Said another way: Zeroing in your steam traps is an easy way to pay ess money for energy and more attention to the environment. Companies around the word are beginning to reaize that rather than being separate chaenges, energy and the environment are and have aways been a singe mission. And that quaity management in one area wi surey impact the other. ST-66

294 The Inverted Bucket Steam Trap Steam Traps Energy Efficient Because It s So Reiabe The inverted bucket is the most reiabe steam trap operating principe known. The heart of its simpe design is a unique everage system that mutipies the force provided by the bucket to open the vave against pressure. Since the bucket is open at the bottom, it resists damage from water hammer, and wear points are heaviy reinforced for ong ife. Wear and corrosion resistance Free-foating guided ever vave mechanism is frictioness, and a wear points are heaviy reinforced. A working parts are stainess stee. Vave and seat are stainess stee, individuay ground and apped together in matched sets. The inverted bucket has ony two moving parts the vave ever assemby and the bucket. That means no fixed points, no compicated inkages. Nothing to stick, bind or cog. Virtuay no steam oss Steam does not reach the water-seaed discharge vave. Continuous air and CO 2 venting Vent in top of bucket provides continuous automatic air and CO 2 venting with no cooing ag or threat of air binding. Steam passing through vent is ess than that required to compensate for radiation osses from the trap so it s not wasted. Purging action Snap opening of the vave creates a momentary pressure drop and turbuence in the unit drained. This breaks up fims of condensate and air and speeds their fow to the trap. Exceent operation against back pressure Since trap operation is governed by the difference in density of steam and water, back pressure in the return ine has no effect on the abiity of the trap to open for condensate and cose against steam. Dependabe operation Simpe, direct operation with nothing to stick, bind or cog. Ony two moving parts the vave ever and the bucket. Freedom from dirt probems Condensate fow under the bottom edge of the bucket keeps sediment and sudge in suspension unti it is discharged with the condensate. Vave orifice opens wide and coses tighty. No buidup of dirt or cose cearances to be affected by scae. Resistance to damage from water hammer Open bucket or foat wi not coapse as a resut of water hammer. ST-72

295 Inverted Bucket Steam Trap Conserves Energy Even in the Presence of Wear Armstrong inverted bucket steam traps open and cose based on the difference in density between condensate and steam the inverted bucket principe. They open and cose genty, minimizing wear. This simpe fact means that inverted buckets are subject to ess wear than some other types of traps. In fact, as an Armstrong inverted bucket trap wears, its tight sea actuay improves. The ba vave and seat of the Armstrong trap provide essentiay ine contact resuting in a tight sea because the entire cosing force is concentrated on one narrow seating ring. An Armstrong inverted bucket trap continues to operate efficienty with use. Gradua wear sighty increases the diameter of the seat and aters the shape and diameter of the ba vave. But, as this occurs, a tight sea is sti preserved the ba merey seats itsef deeper. Corrosion-Resistant Parts The stainess stee vave and seat of the Armstrong inverted bucket steam trap are individuay ground and apped together in matched sets. A other working parts are wear- and corrosion-resistant stainess stee. Armstrong IB Vave Seating/Ba Vave Venting of Air and CO 2 The Armstrong inverted bucket provides continuous automatic air and CO 2 venting with no cooing ag or threat of air binding. Operation Against Back Pressure The Armstrong inverted bucket has exceent performance against back pressure. It has no adverse effect on inverted bucket operation other than to reduce its capacity by the ow differentia. The bucket simpy requires ess force to pu the vave open and cyce the trap. Freedom From Dirt Probems Armstrong designed its inverted bucket to be virtuay free of dirt probems. The vave and seat are at the top of the trap, far away from the arger partices of dirt, which fa to the bottom. Here the up-and-down action of the bucket puverizes them. Since the vave of an inverted bucket is either fuy cosed or open, dirt partices pass freey. And the swift fow of condensate from under the bucket s edge creates a unique sef-scrubbing action that sweeps dirt out of the trap.

297 How to Use the IB Steam Trap Summary Capacity Chart How the Capacity Chart was made The Armstrong capacity chart shows continuous discharge capacities of Armstrong traps under actua operating conditions as determined by iteray hundreds of tests. In these tests condensate at the steam temperature corresponding to the test pressure was used. The choking effect of fash steam through the orifice, as we as the back pressure created by fash steam, were automaticay taken into account. Actua instaation hookups were used so that pipe friction in both inet and discharge ines aso were refected in the resuts. Trap capacity ratings based on cod water tests which produce no fash steam woud be much too high. Orifice tests aso are too high because they ignore pipe friction. Theoretica cacuations of trap capacities have never been conservative. You can rey on Armstrong capacity ratings because they show actua capacities of hot condensate. Heavy sawtooth curves show capacities for traps using maximum possibe diameter orifices for the pressures shown. Thin ine curves extending down to the eft of the heavy curves show the capacities of Armstrong traps at pressures beow their maximum ratings. For exampe: a mode 216 trap with 1/2" orifice good for a maximum working pressure of 8,5 bar wi have a continuous discharge capacity of a itte ess than kg/h at 2,8 bar. How to use the inverted bucket trap capacity chart To seect an inverted bucket steam trap using the Armstrong capacity chart, you must know the condensate oad, safety factor and pressure differentia. Remember, the objective is aways to seect a trap that can 1) operate at the maximum differentia pressure and 2) hande the capacity at the minimum differentia pressure. Consider the foowing typica probems: Exampe 1: Constant Pressure and Condensing Rate Given: Maximum pressure differentia: 5 bar Operating differentia: 4 bar Condensate oad: 133 kg/h times 3:1 safety factor or: 400 kg/h Enter chart at 4 bar and go up to 400 kg/h capacity. This is directy on the 5/32" orifice ine as shown in Chart ST The capacity of this 5/32" orifice at pressures ess than 2 bar is indicated by the thin ine. Foow the ine to the right to the vertica drop at 5 bar. This means this orifice wi operate to a maximum of 5 bar differentia - the other requirement for this appication. Foow the heavy ine back to the eft and note that it's attached to the arrow indicating that the 211, 811 or 881 traps (1811 and 1011 are other possibiities) with the 5/32" orifice wi yied this capacity. This is the trap to use. Exampe 2: Constant Pressure and Condensing Rate but with Possibe High Back Pressure Assume for exampe: Maximum pressure differentia: 6 bar Operating differentia minimum: 3 bar Operating differentia normay: 4 bar Condensate oad: 133 kg/h times 3:1 safety factor or: 400 kg/h To sove the probem, refer to the sawtooth chart, page ST-74. Enter at the minimum differentia pressure (3 bar) and move up unti you intersect a ine that is above 400 kg/h capacity, which is the first thin ine above the heavy sawtooth for the 211, 811 and 881 traps. Note that this is the continuation of the capacity ine for the 5/32" orifice for the 212, 812 and 882 traps. Now foow the ine to the right unti the vertica drop at 8,5 bar differentia. This is within our requirement of 6 bar. Therefore a 5/32" orifice can hande the 400 kg/h condensate oad when fitted into a 212, 812 or 882 trap and that it wi not ock shut at the 6 bar maximum differentia. This is the trap to use since it wi hande the oad at both the minimum and maximum operating differentias, even though it has a maximum operating pressure differentia of 8,5 bar.

Mode 501-SH Maximum Operating Conditions Maximum aowabe pressure (vesse design) : Mode 401-SH: C Mode 501-SH: C To survive this most severe steam service, Armstrong created an inverted bucket trap with a unique accumuation chamber. The chamber coects sufficient condensate to ensure fu discharge cyces. A cup in the chamber foats up and down on the steam inet tube, seaing it off as the condensate eve rises. At the same time as the chamber coects condensate, steam continues to fow under the bucket, making sure that the discharge vave coses tighty unti the condensate rises into the trap body and the bucket fas down. The operation is on/off, no throtting or dribbing. Furthermore, it combines a the advantages of an inverted bucket steam trap: High resistance to wear, corrosion and water hammer with no gaskets. A unique everage system mutipies the force provided by the bucket, to open the vave against system pressure. The mechanism is ocated at the top. No dirt can coect on the orifice.

This combination provides ong-term protection against eaks to the atmosphere and downstream piping. Sef-ceaning action Stainess stee piston sides without rotating between the two vave seaing rings, preventing dirt from damaging the seaing surfaces. Protected vave stem The vave stem and seaing surfaces are competey protected from dirt and corrosion by the stem cap, whether in an open or cosed position. In-ine repairabiity A vave components may be easiy repaced in-ine. Long-term operation Piston vave design assures actuation even after many years without operation. Seaing integrity Fexibe disc springs automaticay provide eak tightness by exerting pressure which keeps the upper and ower vave seaing rings compressed at a times. Seaing tightness is assured by the compression of the seaing rings against the piston and the vave body. This combination of disc springs and dua vave sea rings protects against expansion and contraction due to heating and cooing. This assures dependabe operation, even after years of service. ST-113

344 The Foat & Thermostatic Steam Trap Steam Traps The More Your Steam Pressure Varies, the More You Need Armstrong F&T Traps When steam pressure may vary from maximum steam suppy pressure to vacuum, Armstrong F&Ts are your most energyefficient choice. Our ine of F&Ts brings Armstrong performance, dependabiity and ong ife to trapping services requiring continuous drainage with high air venting capacity. Thanks to separate orifices for condensate and air, they provide continuous condensate drainage and air venting even under conditions of zero pressure. No water sea at inet Inet high on body and condensate discharge vave in the bottom of the body prevent formation of a water sea that coud bock fow of air to vent under very ow pressure conditions. A the benefits detaied beow have been designed into Armstrong F&Ts through ong experience in the manufacture of pressure foat-type drain traps. They assure you of optimum operating efficiency for ong periods with minimum troube. Optiona integra vacuum breaker Provide maximum protection against freezing and water hammer in condensing equipment under moduated contro. They aso eiminate another fitting being instaed in the ine. Corrosion resistance Entire foat mechanism is made of stainess stee. The foat is Heiarc weded to avoid the introduction of dissimiar metas, which coud ead to gavanic corrosion and foat faiure. High-capacity venting of air and CO 2 Buit-in thermostatic air vent discharges arge voumes of air and CO 2 through its separate orifice even under very ow pressure conditions. Long ife and dependabe service Vave is stainess stee in a sizes. Seat is heat treated in 1 1/2" pipe size and arger. Rugged foat mechanism is buit to resist wear, and the stainess stee foat provides exceptionay high coapsing pressure and resistance to hydrauic shock. Water seaed vave Steam cannot reach condensate discharge vave because it is aways under water. Baanced pressure thermostatic air vent coses on steam at any pressure within the operating range of the trap. Operation against back pressure Trap operation is governed soey by the condensate eve in the trap. Back pressure in the return ine wi not render the trap inoperative as ong as there is any pressure differentia to force condensate through the discharge vave. Continuous drainage No pressure fuctuations due to intermittent condensate drainage. Condensate is discharged at very cose to steam temperature. No priming needed. ST-122

345 Foat & Thermostatic Steam Trap Buit as Tough as the Jobs They Do Armstrong foat and thermostatic traps are unique in their super heavy duty construction. Armstrong uses high quaity ASTM A48 Cass 30 cast iron or astm A216 WCB cast stee normay found in pressure vesses rated to 17 bar or 32 bar. Interna mechanisms are made from stainess stee and are heaviy reinforced. No brass cotter pins here. Vaves and seats are stainess stee, hardened, ground and apped to withstand the erosive forces of fashing condensate. Why go to a this troube on traps normay recommended for ow-pressure, moduating service? The answer is in the word moduating. Moduating pressures mean widey varying oads, therma cycing and high air and non-condensabe gas oads. In other words, tough service. Inferior, ightweight construction is a mistake waiting to happen. Trap faiures on moduating pressure may ead to water hammer, corrosion and even heat exchanger damage. Armstrong s pubished capacities are based on actua measurements of traps handing hot, fashing condensate. Competitive F&Ts may utiize theoretica cacuated capacities. Armstrong uses its own steam ab to give you actua capacity especiay important on high-capacity traps such as those in our utra-capacity ine. Not ony does Armstrong offer super heavy duty construction for ong ife and reiabiity, but we aso suppy the data to back up performance. Here s a simpe, easy-toremember summary: The more your pressure varies, the more you need Armstrong F&Ts. Steam Traps ST-123

The condensate controer (CC) configuration was deveoped especiay to meet very arge capacity needs in appications where condensate must be ifted from the drain point to the trap. Under such conditions often referred to as syphon drainage the reduction in pressure that occurs when condensate is eevated causes a portion of the condensate to fash into steam. Ordinary traps, unabe to differentiate between fash steam and ive steam, cose and impede drainage. The LS & MS Series condensate controers (CC) are equipped with a fixed, restricted orifice near the top of the body to beed off the fash steam (and a air present). This permits the trap to function propery on condensate. Liquid drainer with back vent for exceptionay high capacity drainage of iquid from gas under pressure. The iquid drainer (LD) configuration was deveoped to meet very arge capacity needs in draining water and other iquids from air or other gases under pressure. To prevent air or gas binding, the access port in the top of the body serves as a back vent connection to the equipment being drained. For capacity data, see pages LD-453 and LD-476 or consut your Armstrong Representative.

When LS and MS Series units are used in severe service conditions or at pressures exceeding 2 bar, use an anchoring bracket or other supportive measures to minimize stress on piping. Utra-Capacity LS and MS Series units MUST BE WARMED UP in the proper sequence and graduay. Recommended warm-up rate not to exceed 55 C/8 minutes. See your Armstrong Representative. Vacuum Breaker 3/8'' and 1/2'' NPT Many times, condensate wi be retained ahead of steam traps because of the presence of a vacuum. To break a vacuum, air must be introduced into the system by means of a vacuum breaker.

376 SH-300 Bimetaic Steam Trap Carbon Stee For Pressures to 22 bar...capacities to kg/h Steam Traps Connections Screwed BSPT and NPT Socketwed Fanged DIN or ANSI (weded) Materias Body and cap: Vave: Seat: Bimetaic eements: ASTM A105 Chrome Stee - 440C Stainess stee - 303, Boronized Nicke pated Vave Boronized The probem of wiredrawing of vave and seat materias is we known to users of steam traps and other types of vaves. Wiredrawing is a particuar probem to vaves and seats of bimetaic traps, which rey on bimetaic eements to operate. Description The SH-300 steam trap operates on the temperature principe using two ayers of bimetaic eements that have different expansion coefficients. The stem connected to these eements moves a vave into either an open or cosed position. During start-up, the trap is cod so the eements are fat and the vave is wide open. This resuts in air and condensate being easiy removed from the system. In standard operation, the position of the vave depends on two parameters: first, the pressure, which wi cause the vave to open; and second, the temperature, which wi cause the eements to convex and the vave to cose. When no condensate is present and set temperature is reached, the force of the eements is then high enough to competey cose the vave. The SH-300 steam trap can adjust itsef to changing conditions, because if the pressure rises, the higher pressure works on the vave. At the same time, the higher temperature wi work on the eements. To sove the probem of wiredrawing, a new thermochemica surface treatment has been deveoped. The basic vave materia is machinabe hardened chrome stee. Atoms of highy resistant materia are thermochemicay diffused into the vave, giving a ayer of protection and a hardness of 1700 HV to the basic materia. Because of this new thermochemica treatment, the surface of the vave is highy resistant to the erosive action of fashing condensate. The faiure rate of Armstrong bimetaic traps due to wearing out of vave and seat materia is greaty reduced. Specification Bimetaic steam trap with vave boronized, type SH-300 in carbon stee.

377 AB-3000 Bimetaic Steam Trap Stainess Stee For Pressures to 22 bar Capacities to kg/h Description Armstrong's AB-3000 Bimetaic Steam Trap operates by the effect that rising temperature has on bimetaic eements. It adjusts itsef to changing conditions, as the increasing pressure on the vave is compensated by the curving of the bimetaic eements caused by the increasing temperature. The vave of the AB-3000 is speciay treated (boronization) in order to be more resistant to wiredrawing due to erosive condensate fashing. Armstrong's AB-3000 has a seaed, stainess stee body that is ightweight, compact and highy resistant to corrosion. The AB-3000 is repairabe (body and cap can be unscrewed). It is piped through the Armstrong 360 Universa Connector or Trap Vave Station (TVS). This makes it easy to insta and repace, as the trap can be removed whie the connector remains in-ine. The resut is savings in abor cost and increasing in fexibiity, as other trap types (Inverted Bucket, Thermostatic and Thermodynamic) can be instaed on the same connector. Vave Boronized The probem of wiredrawing of vave and seat materias is we known to users of steam traps and other types of vaves.

392 Steam Trap Options and Connectors Thermic Vent Buckets Whenever steam is turned on and off, air wi accumuate in the piping and steam equipment. A trap equipped with a thermic bucket wi discharge this air 50 to 100 times faster than a standard bucket, reducing warm-up time. Thermic vent buckets are suitabe for pressures up to 130 psig (9 bar). A arge vent hoe in the bucket can aso sove air venting probems upon start-up. Thermic Vent Steam Traps Interna Check Vave Interna Check Vaves 1/2'' Thru 2'' NPT Amost a Armstrong inverted bucket steam traps can be equipped with interna check vaves. A check vave is needed between the trap and the equipment being drained in the foowing cases: When the trap is instaed above the unit drained When sudden pressure drops may occur in the steam suppy to the unit Whenever a back pressure exists in the condensate return ine Armstrong spring-oaded, stainess-stee interna check vaves can be screwed directy into the trap inet or into an extended inet tube having a pipe couping at the top. Interna Check Vave In-Line Check Vave 1/2'' and 3/4'' NPT On 1800 and 2000 Series stainess-stee traps, an interna check vave cannot be instaed. Armstrong s CVI in-ine check vave wi sove the probem. Pop Drain for Freeze Protection In genera, a propery seected and instaed Armstrong trap wi not freeze as ong as steam is coming to the trap. If the steam suppy is shut off, a pop drain shoud be used to automaticay drain the trap. Maximum Operating Conditions Pressure: 41 bar Temperature: 177 C O-Ring Vave Retainer SS Poished Ba Body Spring Thermo Drains Thermo Drains are instaed in a Tee ahead of 200 Series traps or repace the drain pug directy in the body of speciay machined 800 Series traps.

418 Tank Heaters

419 Features/Benefits of Armstrong Tank Heaters Appication Fexibiity Four types of tank heaters are offered in severa materias and sizes to suit your specific requirements. Fange Mounted Bayonet Type FBC and FBS Space Savings Fange mounted heaters are instaed on various standard manhoe sizes. You save interna space because ony the heating eement itsef is inside. Steam and condensate connections are outside of the tank. Heat Transfer Efficiency Stiff, heicay wound L fin design for an efficient and ong-asting heat transfer surface. Vertica fin surface provides uniform heating of iquid with a minimum of coking due to hot spots. Base Mounted Direct Type BD Unit & Tank Heaters Fange Mounted Hairpin Type FHC and FHS Durabiity Over Long Life Pipes and headers are of heavy construction (minimum Sch. 40 pipe for stee). Greater thickness means a stronger, more corrosion-resistant design that asts onger. Corrosion Resistance Pipes, headers and connections are weded together for a tough, singe materia joint. Eiminating dissimiar materias precudes gavanic corrosion, thereby engthening service ife. C-376

420 Base Mounted Hairpin Types BHC and BHS Shown Unit & Tank Heaters Fast, Direct Connection Heaters are ready for connection to the steam and condensate systems as suppied. Numerous types of connections are avaiabe. Base mounted heaters come with supports to aow for a proper distance between the tank bottom and the heating surface. This aso heps to minimize the need for interna weding. Longer units are provided with mid-support members to further minimize inside weding and ensure rigid footing. Minimum Instaation Weding Armstrong base-mounted tank heaters are instaed and removed easiy through manhoes, eiminating the need for time-consuming weding inside the tank. C-377

421 Tougher on the Job Unit & Tank Heaters Armstrong tank heaters are buit to withstand the rigorous demands encountered in industria instaations. The heavy-duty features of our units were deveoped in response to a need for tank heaters that coud provide efficient heat transfer without sacrificing structura integrity. These features incude heavy-wa pipes and headers, thick L footed fins and a weded construction. In addition, the mono-metaic construction of our units precudes gavanic corrosion, and the finned surface is rigid enough to withstand high-pressure ceaning. Experience gained over 80 years backs every Armstrong tank heater. As a steam system speciaist, your Armstrong Representative can provide assistance with everything from the boier to the condensate return system. Quaity products from Armstrong, pus the practica knowedge to integrate them into your tota steam system, ensure an efficient and troube-free instaation. Efficient Heat Transfer Finned pipe tank heaters are easier than bare pipe units to insta, remove and repair. They are aso more compact and provide superior efficiency in product heating. Finned pipe tank heaters provide up to 10 times as much heat transfer as an equivaent ength of bare pipe, resuting in ower fim or "skin" temperatures. This reduces coking of the product on the heat transfer surface and discooration of heat-sensitive products. This buidup of deposits on the heater requires that more frequent ceanings be carried out to maintain maximum efficiency and origina heat transfer design conditions. This heicay wound finned pipe is best suited for horizonta units, with the fins being in the vertica pane. This increases the natura convection currents, which increases heat transfer and continuousy wipes the coi surface to maintain ceaniness. Options to Match Your Appications Armstrong tank heaters are avaiabe in four standard configurations: Fange Mounted Hairpin Types FHC and FHS Fange Mounted Bayonet Types FBC and FBS Base Mounted Hairpin Types BHC and BHS Base Mounted Direct Type BD These four configurations offer a range of choices to suit most area coverage and therma performance requirements. Each type incudes a number of ength, width and fin pitch options. A units are avaiabe in seamess carbon stee pipe construction. The hairpin and bayonet types are avaiabe in stainess stee. Liquid heated units and custom designs are aso avaiabe. Critica to the heating and maintenance of temperatures for a broad variety of products, Armstrong tank heaters are widey used in breweries, chemica and food processing pants, oi refineries, paper mis, tank storage farms, and in shipping and other industries.

445 Water Heating and Water Temperature Contro Soutions Steam/Water Heaters Steam/water heaters are typicay cassified as instantaneous, semi-instantaneous and tank-type. Temperature contro can be defined as either feed-forward or feedback. Feedback systems are error-driven and rey upon an outet or downstream thermostatic temperature-sensing device to detect a temperature change requirement and then moduate the steam to effect the heat exchange in an attempt to recover the heater set-point. Feedback systems are reactive, and a significant concern is their speed of response to system and appication temperature contro requirements. Tank-Type Steam/Water Heaters (feedback) Tank-type steam/water heaters typicay incude a temperature sensing eement or coi immersed in a storage vesse with a separate, remote steam contro vave. As a function of their integra and often significant storage capabiity, the poor response times often associated with the reationship of temperature-sensing device and steam contro vave are ess of an issue. Water Heating Tank-Type Steam/Water Heaters are a ess attractive option because: They consume a arge amount of vauabe mechanicaroom rea estate. They have been identified as ampification and coonization points for Legionea bacteria. They have significant eak potentia over time. Tank repair is difficut, and tank repacement often requires mechanica room/buiding structura modifications. They consume energy to heat and maintain what is effectivey a reserve hot water suppy. They require separate steam contro vaves, which require ongoing maintenance. They require thermostatic eement/sensors,which have shown a tendency to wear and eventuay rupture under a heavy cyce oad. They are sow to recover and may run out of hot water during peak oad periods. Tankess Instantaneous Steam/Water Heaters (feedback) Tankess instantaneous steam/water heaters, often referred to as she and tube heat exchangers, do not incude hot water storage capacity. These modes wi rey upon either an outet or downstream temperature-sensing eement with a separate steam contro vave. Tankess Instantaneous Steam/Water Heaters are a ess attractive option because: Lag time from message (thermostat) to action (contro vave) creates therma ag and a resuting temperature swing. Moduating steam suppy can cause condensate evacuation issues, resuting in damage from water hammer and tube bunde corrosion. A cycing phenomenon during ow- or no-demand periods wi cause premature wear to the thermostatic eement. Thermostats typicay fai in an open position, making overheated, scad-temperature water avaiabe to the system. High-maintenance feedback systems with buky tank units ike this one often eak, corrode or rupture a thermostatic contro. Feedback instantaneous systems suffer from ag time, tube bunde corrosion and probems with thermostatic eement deterioration. WH-318

446 Water Heating and Water Temperature Contro Soutions Semi-Instantaneous Steam/Water Heaters (feedback) Semi-instantaneous steam/water heaters typicay incude owercapacity storage, with an integra steam contro vave to deiver the heat exchange through an internay positioned eement or coi. Semi-Instantaneous Steam/Water Heaters are a ess attractive option because: Poor ow-fow temperature contro creates an accumuation tank requirement. Accumuation tank creates recovery-time issues at peak demand. Heating eement/coi in generation/accumuation tank is susceptibe to faiure and cross contamination. Accumuation tanks have been identified as ampification and coonization points for Legionea bacteria. Athough a ower-cost option, semi-instantaneous steam/water heaters are a higher-maintenance seection. Semi-instantaneous steam/water heaters have a shorter service ife before repacement than other choices. Fo-Rite-Temp Feed-Forward Instantaneous Steam/Water Heaters Fo-Rite-Temp feed-forward instantaneous steam/water heaters offer a simpe yet time-proven aternative to traditiona feedback instantaneous, semi-instantaneous and tank-type steam-heating methods. By eiminating the temperature sensing feedback eement and reying upon the actua hot water system demand requirement within the system or appication, feed-forward systems respond rapidy and are extremey accurate. Fo-Rite-Temp Feed-Forward Instantaneous Steam/Water Heater is a more attractive option because: The constant, non-moduating steam pressure within the she eiminates cycing damage. The system demand or fow feed-forward activation eiminates the requirement for either steam contro vave or thermostatic contro device. It deivers a consistent outet temperature (+/-2 C of setpoint) with no therma ag and resuting temperature swing. It is extremey safe because the mixing unit wi position to cod water fow upon faiure of the primary operating component. Semi-instantaneous water heaters are subject to poor recovery time at peak demand, inadequate ow-fow temperature contro and shorter service ife. Water Heating The Armstrong Fo-Rite-Temp can easiy do the work of a storage tank unit many times its size-at ower instaed cost and with minimum maintenance. Even the argest capacity Fo-Rite-Temp requires ony 0.63 m² of foor space.

447 Why the Armstrong Feed Forward Design Gives You a Head Start in Performance, Maintenance and Savings The Armstrong feed forward design eiminates the troubesome temperature reguator and uses a differentia pressure diaphragm vave to reguate fow and contro temperature. The vave teams up with a she and tube heat exchanger to compete the system. The idea is simpe: Overheat water in the heat exchanger and then bend it (as needed) with proportiona amounts of cod water to achieve the correct outet temperature for a wide range of fows. There s no storage tank or potentia heath hazard posed by standing water. Gives you a jump on peak demand periods. The differentia pressure diaphragm acts immediatey upon a change of demand so there s no ag time. You get a the hot water you need - up to the unit s capacity - instanty. What s more, if the diaphragm fais, a spring returns the vave to a cosed position (cod), so there s no danger of scading by accident. Makes maintenance a straight, easy shot. Virtuay everything about the design and operation of the Fo-Rite-Temp reduces maintenance. (See beow.) For starters, the tubes inside the carbon stee she are straight for easy mechanica ceaning. And steam pressure in the heat exchanger is not moduated but constant, which assures condensate drainage and nixes potentia water hammer and corrosion. Pushes you out front in savings. When it comes to repacing a buky storage tank system, the choice is cear. The Fo-Rite- Temp consumes dramaticay ess foor space, and you don t have to tear out was to insta it. In fact, it sips through a standard doorway. Payoff? Lower instaed cost. Another advantage: An energy-efficient Armstrong Fo-Rite-Temp won t waste energy by constanty reheating stored water. You can even insuate the heat exchanger she for greater savings. Water Heating Easy, one-time temperature adjustment Integra mounted contro vave provides rigid construction with no intermediate piping to eak Automatic air venting A controing vaves and moving parts see nothing but cod water - no scaing or vave fouing Water differentia demand actuated contro - instantaneous, proactive temperature contro - no ag time WH-320

449 Contro is based on Pressure Difference The Controing Vave Operating Principe The controing vave operates on a differentia pressure principe. The cod water enters the vave body at ine pressure (P1), which is sensed through the cored body passage on top of the vave diaphragm. The outet pressure (P2) is sensed under the diaphragm and is transmitted to the bottom of the diaphragm through the hoow centra main shaft that is ported to the outet side of the vave. Bended Water P2 P1 Mixing Chamber Vave #3 Over-Heated Water from Tube Bunde Essentiay, there are three vaves operating in unison. Vave 1 contros the fow of the water going through the heat exchanger. It has a spring return so that the vave stays cosed in the event of a diaphragm faiure. The vave begins to stroke at a pressure differentia of 0,02 bar and is stroked competey open at 0,4 bar pressure differentia. P2 Suppy Water P1 Vave #2 Vave #1 Tube Bunde Water Heating At ow fow, Vave 2 contros the amount of bypassed cod water that passes from the inet to the outet mixing chamber, where it is mixed with the overheated water coming from the heat exchanger. Vave 3 works in series with Vave 2, remaining wide open at ower demand and throtting proportionay at higher fows. When it comes into operation, it restricts the fow of cod water that mixes with overheated water coming from the heat exchanger. This takes into account the higher demand and fow rate through the heat exchanger and subsequenty does not heat up as fast as a ow-demand water fow. The water is not in the heat exchanger as ong and therefore needs ess cod water added to maintain a constant temperature. Bended Water Out Suppy Water In High Fow Adjustment Low Fow Adjustment Vave #3 Vave #2 Vave #1 Heated Water from Tubes Suppy Water to Tubes Both Vaves 2 and 3 have externa adjustments. The adjustment for Vave 2 is set during ow-oad fow conditions and contros during the ow fow ranges of the unit. Adjustment of Vave 3 is made during high fows and contros throughout the unit s highfow ranges. A three vaves are integra to the same hoow shaft that is connected to the differentia pressure diaphragm. When there is hot water demand, the diaphragm strokes proportionay based on the demand. When it strokes, due to a change in outet pressure, a three vaves stroke downward equay, positioning a three vaves to perform their instantaneous mixing function without deay.

450 Eiminates Legionea The Legionea Disease The Legionea disease officiay appeared in 1976, when more than 200 peope became sick, 20 of which died, from a mysterious disease at a fatefu American Legion convention in Phiadephia. A year ater, the cause of the disease was discovered - a bacteria that was caed Legionea pneumophiia. Water is its primary medium for growth and the egionea organism is found naturay in streams, ponds, akes and mud. Since then, much has been about the bacteria, how it grows, how it affects peope, what are the ikey symptoms and what precautions shoud be taken to prevent the disease. The right conditions First, the egionea organism must find its way into an idea pace to grow and ampify. Then the water harboring the bacteria is aerosoized into a mist, the egionea organisms now airborne can be transmitted into a susceptibe host. The bacteria can be introduced into airstreams by showers, faucets, whirpoo baths, respiratory therapy equipment, decorative fountains and even misters sometimes used in the produce departments of grocery stores. When the organisms are inhaed, they wi ikey migrate to the deepest part of the ungs where they wi continue to mutipy. It is aso here where the infection wi occur producing pneumonia-ike symptoms. The officia number of Legionea cases in Europe is shown on the encosed graph. However, the exact number of cases is uncear because the symptoms for egioneosis and pneumonia are simiar. Furthermore, one known subgroup of the bacteria can cause Pontiac fever with fu-ike symptoms. Attack the ampifiers The ogica pace to take contro of the probem is to eiminate paces where the bacteria wi ampify or mutipy rapidy. These harbors for bacteria growth are often referred to as ampifiers. It stands to reason then, remove the ampifiers and you minimize the bacteria growth. We know that the bacteria require water, warm temperatures and a food source. Whie the bacteria wi grow between 15 C and 50 C, the optima temperature range for the growth of egionea is between 35 C and 45 C. The egionea bacteria cannot survive in water above 55 C and a sustained temperature in excess of 60 C is necessary to destroy the organism. With these parameters in mind, the number one manmade ampifying source for the bacteria is hot water storage tanks. Cooing towers and evaporative condensers have tended to receive more attention due to many pubicized outbreaks, but arge hot water storage tanks are at the top of the ampifier ist. Storage tanks must go Water systems in hotes, hospitas, nursing homes and industria pants have been inked to outbreaks of Legionnaire disease. Typicay, steam is used to heat water for these arge institutiona buidings and then that heated water is stored in arge buky hoding tanks. In these tanks, conditions are idea for bacteria ampification. Often, the water temperature in storage tanks is maintained in the range of 43 C to 49 C, which is idea for bacteria growth. To hep maintain a uniform temperature and to minimize water temperature stratification in the tank, a recircuating pump is used. Furthermore, scae and other buidup materias in the arge storage tanks and piping furnish the bacteria with a food source and provide protection from the high temperatures and/or chemica disinfection. In order to diminish the egionea disease, the bacteria ampifiers must be eiminated. Feedback instantaneous hot water systems - Not hot enough to ki There is a hot water aternative to bacteria-ampifying storage tanks the tankess instantaneous hot water system. The cassica feedback instantaneous hot water systems are reactive with respect to response time. That is to say, there is a sight deay between the time the system senses a need for more hot water and the time the system responds with more steam to heat the water. Because there is no storage tank with the feedback instantaneous system, the temperature-sensing bub is inserted into the outet water piping. The sensor transmits a temperature signa through a capiary tube to a temperature reguating vave that moduates the steam pressure entering the heat exchanger in order to contro the outet water temperature. The water temperature of a feedback type systems does not get hot enough to eiminate the bacteria instanty. This must be done at a minimum temperature of 60 C or hotter. The outet water temperature is usuay within the range of where the bacteria wi survive. Armstrong Fo-Rite-Temp Armstrong Fo-Rite-Temp is different. It essentiay bends extremey hot water (>70 C) with cod water to deiver water in the required range. Furthermore, the storage tank ampifier has been eiminated with a feed-forward type system.

Note: For capacities, see Capacities and Steam Loads tabe on page WH-328. The DW (doube wa) version of the Armstrong Fo-Rite-Temp instantaneous water heater uses a doube-waed tube to provide positive separation of the steam and water in the heat exchanger. The area between the was of the tubes vents to atmosphere so you can detect tube faiure without crosscontaminating either the steam or water. The Fo-Rite-Temp DW is we suited for a hot water appications where steam is avaiabe and pumbing codes or safety requirements prevent the heating medium and the potabe water suppy from being cross-contaminated. Instas quicky and easiy. The Fo-Rite-Temp DW fits through a standard doorway and requires no externa power source. Requiring ony 0,63 m³ of foor area, the unit mounts easiy on the foor or wa or hangs from the ceiing. Performs dependaby. Simpe reiabiity is the heart of the Fo- Rite-Temp. Its controing vaves encounter ony cod water, so hot water scaing doesn t fou vave operation. The contro vave is aso mounted integra to the heat exchanger to eiminate intermediate piping eaks and minimize maintenance. Constant - not moduating - steam pressure on the heat exchanger assures condensate remova. So there s no subcooed condensate to water hammer or corrode the heat exchanger tubes. Another advantage: You can easiy remove the tube bunde horizontay, which requires no vertica cearance.

Ony when water fows wi a differentia pressure across the diaphragm cause it to ift and therefore the poppet vave to rise against the spring and aow the steam to fow. Water Mixing 3. As fow is reduced, back pressure on the outet side of the diaphragm increases unti water pressure on the both sides of the diaphragm becomes equa. As the pressures equaize, the spring pushes the poppet vave onto its seating and coses off the steam suppy. WM-346

STEAMIX is designed to improve efficiency and reduce risk when mixing STEAM and WATER for washdown. When your process demands high washdown temperatures, adjusting the mix of steam and water becomes much more difficut and dangerous. With the oder stye dua gobe vave Mixing Y, it is ony too easy to introduce too much steam with risky consequences for your personne. Not with STEAMIX! Water Mixing Four Steps to Maximum Safety and Effectiveness 1. STEAMIX has a singe contro ever for ease of temperature seection. With three fu turns from cod to fu hot, STEAMIX can deiver an infinite range of outet temperatures OR can be ocked at a predetermined singe setting that the user cannot override. No proportioning or jugging of inet suppies necessary to find temperature. 2. It is mechanicay impossibe for STEAMIX to operate without cod water pressure upon its main operating diaphragm. Because the operating diaphragm dictates if and how much the steam poppet wi open, the vave is intrinsicay safe. THE UNIT IS INOPERABLE WITHOUT A COLD WATER SUPPLY! 3. Because every moving part of STEAMIX is exercised during operation, and it does not rey upon tighty fitted meta-tometa interna components, high minera content water suppies become more manageabe. Keep using the vave and the free fowing interna components wi remain functiona. 4. STEAMIX, ike a mechanica equipment, has the potentia for interna component faiure. If the primary operating mechanism (diaphragm) within STEAMIX fais, the unit wi pass ony cod water. WM-349
