Coal is a variety of solid, combustible, sedimentary, organic rocks, 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. Carbon is the main component of coal, which also contains varying amounts of other components, like hydrogen, oxygen, sulphur and other impurities. Main parameters used to define coal are calorific value, ash, moisture and sulphur. Many different classifications of coal are used around the world, reflecting a broad range of ages, composition and properties.
