What is a Power Plant and How does it Work? RealPars

In its simplest form, a Power Plant, known also as a Power Station, is an industrial facility used to generate electricity. To generate power, an electrical power plant needs to have an energy source. One source of energy is from the burning of fossil fuels, such as coal, oil and natural gas. Then we also have nuclear power, and finally ...

How Coal Works | Union of Concerned Scientists

How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.

Coal gasification Wikipedia

In industrial chemistry, coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and ...
