How a Coal Plant Works - TVA

19/06/2021  How a Coal Plant Works 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.19/06/2021  How a Coal Plant Works Coal-fired plants produce electricity by burning coal in a boiler to produce steam.

Coal-fired power station - Wikipedia

A coal-fired power station or coal power plant is a thermal power station which burns coal to generate electricity. Coal-fired power stations generate over a third of the world's electricity but cause hundreds of thousands of early deaths each year, mainly from air pollution. A coal-fired power station is a type of fossil fuel power station. The coal is usually pulverized and then burned in a pulverized coal-fired boiler. The furnace heat converts boiler water to steam, which is then uA coal-fired power station or coal power plant is a thermal power station which burns coal to generate electricity.
