In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt.
Read MoreFire-tube boilers are available in single fire-tube and double fire-tube versions. The single fire-tube boiler with water-cooled reversal chamber and burner transit can supply steam to 35 t/h. The supplied pressure can vary from 0.5 to 40 bar (g). The hot water boilers deliver a capacity of 0.5 to 22 MW.
Read MoreWith water tube boilers, the heat surrounds the water tubes. This results in less stress on the boiler as a unit, as compared to fire tube designs. The water that has been heated inside the tubes rises to the top of the boiler and into the steam drum.
