Coal 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 primarily used as fuel to generate electric power all over the world. In coal-fired power plants, bituminous coal, sub-bituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity. The ranks of coals, from those with the least carbon to those with the most carbon, are lignite, sub-bituminous, bituminous, and anthracite. MOQ : 30,000 MT Supplied from Indonesia.

The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter. The principal use of anthracite today is for domestic fuel in either hand-fired stoves or automatic stoker furnaces. It delivers high energy per its weight and burns cleanly with little soot, making it ideal for this purpose. Its high value makes it prohibitively expensive for power plant use. Due to fewer impurities and the highest calorific value, the global demand for anthracite has increased, increasing the anthracite mining market. Compared with other coal types, anthracite has less residue and impurities after combustion, and the flue gas is negligible, making it an efficient fuel.
