What Is Coal and What Is It For? Fossil Fuel

Coal is a fossil fuel, a sedimentary rock of organic origin.Its thermodynamic properties allow obtaining a large amount of heat energy during its combustion process. The energy obtained is called fossil energy.It comes in black or dark brown. It is a limited natural resource. Generation is a process of several million years, while the consumption of this energy resource is very fast.

Lignite - Wikipedia

Brown coal, broad and variable group of low-rank coals characterized by their brownish coloration and high (greater than 50 percent) moisture content. These coals typically include lignite and some subbituminous coals.In Great Britain and other countries, the term brown coal is used to describe those low-rank coals (lignite and subbituminous coal) that generally have a brown colour.

Lignite coal Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Lignite has a low heating value and a high moisture content and is mainly used in electricity generation.

How is brown coal made? - AnswersToAll

Brown coal (lignite) is classed as a low-rank coal because it has a high ash and moisture content, and less carbon, which means that it produces less energy when it is heated. It is not suitable for the export market and is used to generate power for the Australian domestic market.

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.

Coal | National Geographic Society

Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.

Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

Coal is also used as a power source for factories. There it is used to heat steam, and the steam is used to drive mechanical devices. A few decades ago most coal was used for space heating. Some coal is still used that way, but other fuels and coal-produced electricity are now used instead. Coke production remains an important use of coal.
