TVA - How a Coal Plant Works

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.

How Does a Coal Power Plant Work?

Pollutants from coal power plants like carbon dioxide, sulphur dioxide, and nitrogen oxide can also affect the environment. Thermal power plants are the biggest producers of Carbon Dioxide. The boiler for typical 500 MW units produces around 1600 tons per hour of steam at a temperature of 540 to 600 degrees Centigrade.

Coal & electricity | World Coal Association

Steam coal, also known as thermal coal, is used in power stations to generate electricity. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high ...

How Coal Works | Union of Concerned Scientists

Dec 15, 2017 · Most of the coal burned in US power plants is bituminous or subbituminous coal. A fifth type, called metallurgical (or “coking”) coal, is used for steelmaking. All types of coal also contain sulfur, which, when burned, releases toxic air pollution.  Sulfur content is determined by the conditions under which the coal is formed.

Coal Mining and Processing | Energy Trends Insider

Processing the Coal After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Source: Energy Information Administration

Coal - Wikipedia

Coal burnt as a solid fuel in coal power stations to generate electricity is called thermal coal. Coal is also used to produce very high temperatures through combustion. Efforts around the world to reduce the use of coal have led some regions to switch to natural gas and electricity from lower carbon sources.

Coal and Air Pollution | Union of Concerned Scientists

Jul 28, 2008 · US coal power plants emitted more than 3.1 million tons of SO2 in 2014.
