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

Natural circulation boiler - Wikipedia
Natural Circulation Boiler in construction. In a natural circulation boiler the circulation is achieved by the difference in density when the water in the boiler is heated. In natural circulation steam boilers the circulation of water is by convection currents, which are set up during the heating of water.
