Lignite is also called brown coal. Lignite has a colorific value of less than 5 kw/kg approximately.Subbituminous coalSubbituminous coal is also called black lignite. Subbituminous coal black and contains 20-30 % moisture. Subbituminous coal is used for generating electricity and space heating. Subbitumnious coal has calorific values ranging from 5 - 6.8 kW/kG approximately.Bituminous coalBituminous coal is a soft, dense, black coal. Bituminous coal often has bands of bright and dull material in it. Bituminous coal is the most common coal and has a moisture content less than 20 %. Bituminous coal is used for generating electricity, making coke, and space heating.Bituminous coal has calorific values ranging from 6.8 - 9 kW/kG approximately.Anthracite coalOften referred to as hard coal, anthracite is hard, black and lustrous. Anthracite is low in suplhur and high in carbon. It is the highest rank of coal. moisture content generally is less than 15 %.Anthracite has a calorfific values of around 9 kW/kG or above.
