What is a Fire tube boiler? The universal type of steam boilers is the smoke tube or fire tube boiler where the heat and gases of combustion (from furnace) pass through tubes that are enclosed by water. While in water tube boilers, water passes through tubes.Mostly used boiler in small and medium industries with different fuels and steam pressure requirements.

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. The fire-tube boiler developed as the third of the ...

This gas oil steam boiler is horizontal type,fire tube,three pass shell boiler.It is designed with a combustion chamber with large volume...

Introduction Fire Tube Steam Boilers are the most traditional technique for the production of saturated steam, high pressure hot water or superheated steam for a range of outputs from 250 to 50 000 kg/h (175 to 34 000 kW). Operating Principle Steam is generated by heating a large volume of water in a pressurised drum by means of hot gases, which are produced from the combustion of liquid or ...

A high pressure watertube boiler[1] (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace ...

As the water and steam both are in same vessel a fire tube boiler cannot produce steam at very high pressure. Generally it can produce maximum 17.5 kg/cm 2 and with a capacity of 9 Metric Ton of steam per hour. Types of Fire Tube Boiler. There are different types of fire tube boiler likewise, external furnace and internal furnace fire tube boiler.

There are different types of boilers classified based on their boiling process. These are main three type of boilers listed below:. Fire Tube Boiler: In a fire tube boiler, hot gas passes through the pipes and boiler feed water is inside the shell to be converted into steam.
