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.

5 Transport of Coal and Coal Products | Coal: Research and ...

Like all fuels, coal must be transported to an end user before it can be used.Specific transportation needs vary—Gulf Coast lignite is generally transported over very short distances to minemouth power plants, Appalachian and Illinois Basin coals are typically transported over somewhat longer distances from mine to market, and coal mined in the Powder River Basin may travel distances ranging ...

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

How Does a Coal Power Plant Work? - Bright Hub Engineering

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. Learn how the process works as well as interesting ...
