coal classification | Types & Facts | Britannica

Coal classification, any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users (e.g., for power generation and coke manufacturing) and to researchers studying the origin of coal.

Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

Bituminous coal is formed when a sub bituminous coal is subjected to increased levels of organic metamorphism. It has a carbon content of between 77 and 87% on a dry ash-free basis and a heating value that is much higher than lignite or sub bituminous coal. On the basis of volatile content, bituminous coals are subdivided into low-volatile bituminous, medium-volatile bituminous, and high ...

Circular 891 - Guidelines - USGS

Coal resources classified as reserves must be considered as economically producible at the time of classification. Conversely, coal not currently producible at a profit cannot be classified as reserves. However, there are situations in which mining plans are being made, lands are being acquired, or mines and plants are being constructed to produce coal that does not meet economic criteria for ...

Coal gasification - Wikipedia

Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas". Coal gas is combustible and was used for heating and municipal lighting, before ...
