Boiler (power generation) - Wikipedia

The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or natural gas. Nuclear fission is also used as a heat source for generating steam. Heat recovery steam generators (HRSGs) use the heat rejected from other processes such as gas turbines.. Solid fuel firing. In order to create optimum burning characteristics of the fire, air needs to be supplied
