23/4/2016 · The pressure of the steam is about 165 bar. These boiler falls under the category of high pressure boiler. The steam generation rate in water tube boiler is high i.e. 450 tonnes per hour. For a given power the floor area required for the generation of …
23/4/2016 · Fire Tube Boiler It is a boiler in which the hot flue gases is present inside the tubes and the water surrounds these tubes. As fire is present insides the tubes, hence it is called as fire tube boiler. The steam produced by these boilers have pressure of about 25 bar

This is a horizontal drum axis, multi-tubular, natural circulation, artificial draft, forced circulation, medium pressure, solid fuel fired fire tube boiler that has an internal fire furnace. It is capable of producing high steam rate and hence it is used for railway locomotive engines and in marines.
20/6/2020 · A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
Fire tubeor "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam cir-culates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel
These boiler falls under the category of high pressure boiler. The steam generation rate in water tube boiler is high i.e. 450 tonnes per hour. For a given power the floor area required for the
Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, C. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.
k. Superheater, drums and boiler tube system maximum design pressure, Vendor to specify, but a minimum of 300 kPa (3 bar) above operating pressure is required. l. Steam drum and boiler tube system maximum design temperature specified on data sheet m.
A firetube boiler annually uses 450,000 million Btu (MMBtu) of fuel while op-erating for 8,000 hours at its rated capacity of 45,000 pounds per hour (lb/hr) of 150 pounds per square inch gauge (psig) steam. If scale 1/32nd of an inch thick is allowed to form on the
