Ever wonder how your boiler is creating steam Fire Tube Boiler is the type of boiler in which the water is flowing outside (Surrounded) the tube and hot gases which are produced by the combustion chamber are inside the tube and the further boiler is used to rotate the turbine blade and that used for the generation of electricity. After knowing definition now moving to types of fire tube boiler

Fire Tube Boiler. In Fire Tube Boilers, hot flue gases will be flown inside the tube and these tubes are surrounded by water. These are the low-pressure boiler which cannot generate much heat compared to water tube boilers. As the production of heat is less the overall efficiency of this boiler is also low A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or 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.. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank. Firetube boilers are used for low capacity steam production applications, mainly for vessels having diesel engines as main propulsion system. On such vessels, steam is required for auxiliary machinery. Such boilers have simple operation and can run properly even with medium quality water

Fire-tube boiler: This is a boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes.
