June 12, 2020

A boiler is a closed vessel in which fluid (generally water) is heated up to high-pressure steam. The boilers are used for the generation of steam. They are mostly used in power plants where steam turbines are used for the generation of electricity. Both fire tube and water tube boilers have advantages and disadvantages in different industrial applications.

Efficiency of the water tube boiler is more than that of fire tube and lies within the range of 85 to 90 %. efficiency of water tube boiler can also be increased by using different accessories.
