Electricity explained

Coal was the third-largest energy source for U.S. electricity generation in 2022—about 18%. Nearly all coal-fired power plants use steam turbines. A few coal-fired power plants convert coal to a gas for use in a gas turbine to generate electricity. Petroleum was the source of less than 1% of U.S. electricity generation in 2022.

Circulating Fluidized Bed Combustion

In fluidized bed combustion (FBC) ( Fig. 4 ), crushed coal, 5–10 mm in particle size, is burned in a 1000-mm-deep bed of 0.5- to 3.0-mm particles consisting mainly of additive sorbents (limestone or dolomite) and coal ash. The bed is fluidized by a blast of air through a distributor plate at the bottom of the bed.

How does a coal-fired boiler work?

By Perrine Juillion / June 25, 2019. Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
