How a Coal Plant Works TVA. Coalfired 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 price

Processing the Coal After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is loed 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.

Coal washing is an indispensable process for deep processing of coal. Coal preparation plant also named coal wash plant. The coal directly mined from the mine is called raw coal. The raw coal is mixed with many impurities during the mining process, and the quality of the coal is different.

Raw coal may be sold as mined or may be processed in a beneficiation/washing plant to remove noncombustible materials (up to 45% reduction in ash content) and inorganic sulfur (up to 25% reduction). Coal beneficiation is based on wet physical processes such as gravity separation and flotation. Beneficiation produces

Coal fired power plants also known as coal fired power stations are facilities that burn coal to make steam in order to generate stations, seen in Figure 1, provide ~40% of the world's electricity. Countries such as South Africa use coal for 94% of their electricity and China and India use coal for 7075% of their electricity needs, however the amount of coal China uses ...
