How Does a Coal Power Plant Work?
How Coal Power Plants Produce Electricity. The heat from combustion of the coal boils water in the boiler to produce steam. In modern power plant, boilers produce steam at a high pressure and temperature. The steam is then piped to a turbine. The high pressure steam impinges and expands across a number of sets of blades in the turbine.

Selecting Coal for use in Boilers based on Characteristics
Bituminous coal is commonly used in power plant boilers for generation of electric power. Bituminous coal has a higher boiler heating value than either sub-bituminous or lignite, but less than that of anthracite. Bituminous coal is mined chiefly in the Midwest and Appalachian regions. Plant chemists conduct analyses of the coal as it is received.
