Coal-fired power station - Wikipedia

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 used to spin turbines that turn generators.Thus chemical energy stored in coal is converted successively into thermal energy, mechanical energy and, finally, electrical energy.
