Coal is a combustible sedimentary rock formed from vegetation that has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years. Coal is composed primarily of carbon, and also contains varying amounts of other components, like hydrogen, oxygen, sulphur and other impurities.
The course of the carbonation has led to various types of coal, which are the following turf, lignite, sub-bituminous and bituminous coal, anthracite and graphite. From turf to anthracite, the carbon C content is increasing, while the moisture 2 and the volatile components CO2, CH4, NH3 are decreasing.
