Boilers - University of Alabama

The water tube diameter is much smaller than the shell diameter of a fire-tube boiler, so much higher pressures can be obtained, well over 2000 psi. The furnace and boiler tube area must be surrounded by a heavily insulated refractory wall to prevent heat transfer through the boiler walls. The refractory lining is a high maintenance item.

How does a Fire Tube Boiler work?| What are types of Fire

A fire-tube boiler is a boiler in which fire tubes are immersed in water, and the hot flue gases produced by the combustion chamber flow inside the fire tubes. The hot flue gases transfer their heat to the outside water through the conduction process. When heat transfers to the water, it converts into steam.
