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

Fossil fuel power station - Wikipedia

A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity.Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator.The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.
