2 Metropolitan - Steam Boiler The Metropolitan is a range of high pressure conventional three pass wet back steel horizontal shell and tube steam boilers, utilising a combustion chamber and two passes of tubes. The boiler is available in sizes ranging from kg/h (from and at 100ºC feed water temperature) and is suitable for firing on natural gas, LPG and oil with a choice of burner manufacturers. The boilers are supplied fully packaged for ease of installation and only require connection to electricity, water, steam and blow down lines. General Description The Metropolitan range of steam boilers is available in outputs up to kg/h. The boiler has a high water volume and large steam space, which allows it to satisfy high steam demands for short periods and minimizes the formation of water droplets. The boiler has a low heat release rate, due to the large heating surface, which helps to reduce emissions and improve the efficiency. have a standard working pressure of up to 10 bar, but higher pressures are available on request. The boilers have a typical efficiency of up to 90% across the range, based on a net calorific value of the fuel. Performance Features Outputs up to kg/h Large steam space High water volume Metropolitan steam boiler High quality saturated steam Up to 10 bar working pressure (higher pressures available on request) up to 90% net efficiency Composite waste heat design option The boilers are fully packaged and are supplied with burner, control panel, twin feed water pumps and ancillary mountings, which are pre-wired and fitted to the boiler. In some cases these items are supplied loose for site installation. The internal parts of the boiler are easily accessible for cleaning and inspection, by opening the two front hinged access doors. This gives good access to the front tube plate and the second and third pass boiler tubes. The boiler is supplied with a set of cleaning tools. Metropolitan boilers should be installed in accordance with relevant standards, codes of practice and current building regulations. Water treatment is recommended for all steel shell and tube boilers and a water treatment specialist should be consulted for advice on this matter. 2

3 Design & Construction The Metropolitan is a range of three pass wet back horizontal shell and tube steam boilers. The boiler design incorporates a corrugated combustion chamber, which helps to reduce thermal stresses during expansion and improve overall efficiency. The boilers are manufactured using flanged tube plates, which also reduces thermal stresses during the combustion process, The boilers have a large surface of evaporation and a large steam space which provides high quality steam. They also have a generous shell and furnace size, to ensure boiler outputs are easily achieved. The boilers are insulated with a high density mineral wool blanket, enclosed in a sheet steel casing. All Metropolitan steam boilers are designed and manufactured, inspected and tested as required by the relevant provisions of the Pressure Equipment Directive 97/23/ EC and also in accordance with the EC type - examination certificate (module B). The boilers are CE certified. Boilers manufactured and constructed to EN are available on request. are subject to X-ray and ultrasonic testing and they are hydraulically pressure tested in the factory.

The burner is bolted to the boiler front plate and pre-wired to the control panel.

4 Combustion & Controls are suitable for firing on either gas, oil or dual fuel. A burner is normally supplied and matched to the boiler to give either high/low or fully modulating operation, which ensures optimum operating efficiency to suit specific requirements. The burner is bolted to the boiler front plate and pre-wired to the control panel. The boiler control panel supplied satisfies all mandatory requirements and is generally located on the side of the boiler, but in some cases depending upon the burner specification and size, it may be floor mounted adjacent to the boiler. Boiler control panels can be supplied to meet customer requirements and generally include, alarms, relays, switches and feed pump motor starters. The panel is pre-wired and connected to level controls, pressure switches, feed water pumps and other ancillary items located on the boiler. Volt free kits can also be supplied, details available on request. The control panel requires a 400v 3 phase electricity supply and is supplied with a suitable fused isolator. Ancillary Mountings The Metropolitan steam boiler comes fully packaged and is supplied with the following standard fittings: Cast Steel Crown valve Blow down valve with key two high lift safety valves two reflex type water level gauges, complete with blow down cocks Pressure switches for control of high/low and modulating burners Safety pressure switch Two low level safety probes Twin feed water pumps (on /off control), strainer, feed check and non return valve Pressure gauge Probe type on/off water level controls Boiler control panel Top inspection opening & hand hole inspection covers Ladder and Gantry The fittings are all mounted on the boiler and are pre-wired and piped accordingly in the factory. The water feed pumps are fitted to the boiler support brackets and can be located on either the left or right side of the boiler. However this needs to be specified at the time of order. An additional range of boiler mounted accessories are available, including: Timed bottom blow down valve Self monitoring water level controls Auto TDS system Sample cooler Modulating feed water control Invertor driven pumps and/or burners Flue gas economiser Burner acoustic shrouds PM5 panels (Supplied loose for remote mounting) Composite Waste Heat Boilers can also be manufactured to a composite design, utilising waste heat from another heat source such as a Combined Heating and Power plant or an industrial process. This type of steam boiler is normally fired on gas or oil using a burner as the primary heat source, but it has an additional pass through which waste heat gases flow. The waste gas gives up its useful heat to the boiler when available and it is then discharged into the flue. In some cases the waste heat gas may be the primary heat source, with oil or gas burners used to top the system up when required. Boilers of this type are designed specifically to suit site and system requirements and are available on request. 4
