Boiler - Energy Education

Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity. The process that does this is known as the Rankine cycle. The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam.

Can we use biomass fuel in coal-fired boilers?

Biomass boilers are different from coal-fired boilers. The grate gaps of coal-fired boilers are too large for wood pellets. In biomass boilers, the wood pellets are gasified and fed by a hopper at a constant speed so that they can burn sufficiently. After gasification, the hearth is filled with high-heat flames with little smoke.
