    OverviewOperationCoal power generationCarbon dioxide emissionsPollutionTransport and delivery of coalEfficiencyEconomics

    As a type of thermal power station, a coal-fired power station converts chemical energy stored in coal successively into thermal energy, mechanical energy and, finally, electrical energy. 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 used to spin turbines which turn generators. Compared to a thermal power station burning other fuel types, coal specific fuel processing and ash disposal is required.

  • How a Coal Plant Works tva

    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.
