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…

How a Coal Plant Works - TVA.com

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

In a coal-fired steam station – much like a nuclear station – water is turned into steam, which in turn drives turbine generators to produce electricity. Here’s how the process works. 1. Heat is created Before the coal is burned, it is pulverized to the fineness of talcum powder.

Fossil fuel power station - Wikipedia

Thermal power plants are one of the main artificial sources of producing toxic gases and particulate matter. Fossil fuel power plants cause the emission of pollutants such as NOx, SOx, CO2, CO, PM, organic gases and polycyclic aromatic hydrocarbons. World organizations and international agencies, like the IEA, are concerned about the environmental impact of burning fossil fuels, and coal in particular. The combustion of coal contributes the most to acid rain and air pollution, and has been connected with globa…
