Oil atomizers are of the tip emulsion design, using steam or compressed air as the atomizing medium. Oil must be delivered to the nozzle at viscosities below 00 SSU. The ruggedly constructed burners consist of three basic sections. Front Section. A heavy cast iron mounting plate, with slotted mounting holes, fitted with a high strength castable burner tile rated for service up to 2600 F. A carbon steel or 304 stainless steel tile support jacket is available as an option. Center Section. A circular gas plenum with bottom gas inlet, a combustion air diffuser, a connection for a spark-ignited premix gas pilot (for natural gas or propane), and a threaded boss to accommodate a flame rod. Rear Section. Hinge-mounted includes blower motor, impeller, intake guard, a large reinforced glass observation port, provisions for mounting a flame detector, the flange-mounted oil atomizer, and the manual or motorized firing rate control. An accurate linked valve ratio control is provided by a compact arrangement of linkage rods and swivels that connect the internal main air proportioning shutters with a butterfly gas valve and/or a Sensitrol Oil Valve. Fuel oil enters the Sensitrol Oil Valve via a swivel type joint mounted on the hinge. Basic Gas Burner consists of the above three sections fitted with a manually positioned and lockable firing rate control lever (shown in burner photo) and a butterfly gas valve with linkage assembly. Refer to Bulletin 640 for main and pilot gas accessories. Basic Light Oil Burner consists of the three basic sections described above, with the following equipment: a manually positioned and lockable firing rate control lever, a Sensitrol Oil Valve with linkage assembly, and a flange mounted oil atomizer assembly. Refer to Table 2 for oil and atomizing medium pressure/flow requirements. Specify this burner arrangement for oils up to and including #4 grade. Basic Heavy Oil Burner is similar to the light oil burner except atomizer, Sensitrol Oil Valve, and oil piping are sized and arranged to accommodate heavy oil or crude oil. Oil temperature is maintained electrically within the burner through four low wattage cartridge heaters: one within Sensitrol valve body, two in heater blocks attached to oil tube, and one in a heater block attached to the nozzle. The hinge assembly is fitted with a hot oil return valve (shown in the photograph). This burner is recommended for all heavy oils, including blended grades. Basic Dual-Fuel Burner is similar to oil burner except provision is made for burning either gas or a pre-selected grade of oil. A dual-fuel burner fitted for heavy oil permits use of any grade, ranging from diesel through very heavy #6. Flame Supervision and Control. There is a long list of optional accessories that can be added to the basic burners described above. In many applications of this burner, the combustion chamber is below 400 F. Electronic flame supervisory systems are strongly recommended. Such systems are offered by North American and others. A specially designed system is available for boilers. Your local North American sales engineer can help select burner accessories required to make a firing system that will be reliable, efficient, and safe to operate.

Blower Business Group 43, 53, 63 PACKAGED AUTOMATIC BURNERS Engineering Specifications 63 May 994 Features of NORTH AMERICAN Packaged Automatic Burners BUILT-IN BLOWER: Delivers 00% of combustion air required for burner operation. Eliminates need to install an expensive and bulky air delivery system. CONTROL VARIETY: Building from the basic burner package, control systems are available along with many pre-packaged gas and oil trains, motorized controls, flame safeguard accessories, and programming systems. WIDE RANGE OF CAPACITIES: 2 500 000 to 30 000 000 Btu/hr, in six frame sizes. Typical air turndown is 4: on standard models. Greater turndowns are available for special applications. RUGGED, VERSATILE, AND RELIABLE: An ultra stable burner designed to operate in chambers at temperatures up to 2000 F and under negative or slightly positive pressures. Cold, tight chambers present no problem for this rugged, lowmaintenance workhorse. Proven reliability while operating with natural gas, #2 fuel oil, and #6 fuel oil. Crude oil, and pitch have also been successful, however, these are often application dependent. Consult North American Mfg., Cleveland, for applications with these fuels.

NORTH AMERICAN Mfg. Co. Engineering Specifications 63, 5-94 Cleveland, OH 4405-5600 USA Page 2 The Packaged Automatic Burners are ideal for steel firebox, scotch marine, cast iron sectional, and watertube boilers, and industrial process heating equipment, such as air heaters, dryers, oil heaters, ovens, and incinerators. Six frame sizes produce a wide range or capacities (2 500 000 to 30 000 000 Btu/hr). Design: The 43 Burner is for any fuel gas; the 53 for fuel oils, and the 63 for dual-fuel (combination gas and oil). All are of the nozzle mix design with an integral blower to supply 00% combustion air. Oil atomizers are of the tip emulsion design, using steam or compressed air as the atomizing medium. The hinged construction provides quick and complete accessibility. Fixed fuel lines need not be broken for service because fuel oil enters through the burner hinge and gas enters through a stationary gas section. Construction: This rugged burner consists of a cast iron mounting plate, with slotted mounting holes, fitted with a high strength case refractory burner tile rated for service up to 2600 F. A stainless steel tile support jacket is available as an option. The grade of stainless steel is application dependent. The circular gas plenum has a bottom gas inlet, a combustion air diffuser, and a spark-ignited premix gas pilot (for natural gas or propane). The hinge-mounted blower section includes the blower motor, impeller, intake guard (or optional intake silencer), a large reinforced glass observation port, provisions for mounting a flame detector, and flange mounted oil atomizer. An accurate linked valve ratio control is provided by a compact arrangement of aircraft-quality linkage rods and swivels that connect the internal main air proportioning shutters with a butterfly gas valve and/or a Sensitrol oil valve and the modulation motor. Standard Components: The 4/5/63 Burner includes the pilot gas regulator, pilot gas solenoid (2nd solenoid optional), 6000 volt ignition transformer, electric modulating control motor (air motor optional), low combustion air interlock, and burner hinge interlock switch. Oil burners also include a solenoid valve (or optional motorized automatic valve), piped between the hinge and atomizer assembly. All electrical components are wired to the burner mounted NEMA 4 junction box. Turndown: Typical air turndown is 4: on standard models. Greater turndown can be achieved with an optional blower air inlet controller. Consult North American, Cleveland, for details. Excess Air: Standard burner linkage is factory set to deliver 20% excess air. Rates greater than 20% are possible through reduction of fuel input. Flame Characteristics: These burners generate welldefined medium length flames. See Supplement 63- for flame sizes. Chamber Pressures: Designed for stable operation in chambers with pressures ranging from 0.5"wc to 2.0"wc. The "N" burner is specified on applications with 0 to 0.5"wc chambers (i.e., 2-pass boilers, dryers, heaters, etc.) and the "P" burner is specified on those with 0. to 2.0"wc chambers (i.e., 3-pass boilers, etc.). Consult North American, Cleveland, for burner performance with other pressures. Underwriters Laboratories Listing: The Model 4/5/63 Burners have been designed in accordance with the requirements of the Underwriters Laboratories. Consult North American Mfg., Cleveland, for labeling service. Hinged construction provides for complete accessibility to burner internals. WARNING: Situations dangerous to personnel and property can develop from incorrect operation of combustion equipment. North American urges compliance with National Safety Standards and Insurance Underwriters recommendations, and care in operation. Printed in USA AGS797-ES63-6000
