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.
  • Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water.
  • The examples of this boiler are the simple vertical boiler, Cochran boiler, Lancashire boiler, Cornish boiler, Locomotive boiler, Scotch marine boiler and Velcon boiler.


1.Fire tube boiler is in simple design and has a low maintenance cost.
2.Less skilled operation are sufficient for efficient operation.
3.Fire tube boiler can be used in small industry.
4.Treatment of feed water is not very essential in fire tube boiler.
5.No pure feed water is required in FTB, So cost can be minimized because pure feed water is costly.
6.For the same power output, the cost of a fire tube boiler is less as compared to a water tube boiler.


1.The maximum working pressure of fire tube boiler is up to 20 bar.
2.Overall efficiency is up to 75%
3.It requires more floor area for a given output.
4.Load fluctuation cannot be easily handled.
5.The rate of steam generation and quality of steam for suitable power generation are not much better than the water tube boiler.
6.This is used in small power plants.


1.Fire Tube Boilers are mostly used in railways,
3.and industrial sectors.
