Coal Mining and Processing

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 fired power plant

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?

Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.
