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 pulverized coal-fired boiler. The furnace heat converts boiler water to steam, which is then u

Coal-Fired Thermal Power Plant - an overview ...

Coal is the dominating fuel source used in thermal power plants for generation of electricity. At the coal-fired thermal power plants, the raw coal is first pulverized to the shape of flour before it is force-fed to the furnace. During the pulverization process, the clay particles entrapped in the cracks of coal get separated from the coal.

Thermal power station - Wikipedia

Almost all coal-fired power stations, petroleum, nuclear, geothermal, solar thermal electric, and waste incineration plants, as well as all natural gas power stations are thermal. Natural gas is frequently burned in gas turbines as well as boilers. The waste heat from a gas turbine, in the form of hot exhaust gas, can be used to raise steam by passing this gas through a heat recovery steam generator (HRSG). The steam is then used to drive a steam turbine in a combined cycleplant that improves overall efficiency. Power stati
