Bituminous coal is a dense sedimentary rock, usually black, but sometimes dark brown, often with well-defined bands of bright and dull material; it is used primarily as fuel in steam-electric power generation, with substantial quantities used for heat and power applications in manufacturing and to make coke. There are actually two main types of coal: ‘thermal’ coal, which is mostly used for power generation, and ‘metallurgical’ coal, which is mostly used for steel production. Thermal coal is more abundant, has lower carbon content and is higher in moisture than metallurgical coal.
