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

Dec 04, 2008 · The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2. The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam.

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.
