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.
