A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.
• It is too early to pick winners for coalbased power generation with capture. • Emissions from coalbased power generation can be very low; and with CO 2 capture, even lower, to the extent of really being very clean. • With CO 2 capture and sequestration, coal can provide electricity at a cost competitive with wind and nuclear.
The power plant that uses coal to generate heat is known as the thermal power plant. The thermal power plant is a conventional power plant. Sometimes, the thermal power plant is also known as a stealturbine power plant or coal power plant.
