Excerpts from RockTalk Volume 8, Number 2, 2005 wermac

Coal is a solid but brittle, carbonaceous black sedimentary rock that burns. It is made up of carbon, hydrogen, oxygen, nitrogen, and lesser amounts of sulfur and other trace elements. Coal is divided into four classes: lignite, subbituminous, bituminous, and 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 a type of fossil fuel, 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. Vast deposits of cCoal

Coal

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 fuelCoal is a sedimentary deposit composed predominantly of carbon that is readily combustible. Coal is black or brownish-black, and has a composition that (including inherent moisture) consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material.

Coal is a solid, brittle, combustible, carbonaceous rock formed by the decom-position and alteration of vegetation by compaction, temperature, and pressure. It varies in color from brown to black and is usually stratiﬁed. The source of the vegetation is often moss and other low plant forms, but some coals containCoking. Coking coal is an essential raw material for the production of iron and steel. Coke is a solid carbonaceous residue formed from coking coal (a low-ash, low-sulphur bituminous coal, also known as metallurgical coal), which is used in make steel and other iron products [].Coke is produced by burning coal at temperatures up to 1000 °C in Chemistry and geology of coal: nature, composition, coking
