Oct 07, 2019 · Bituminous coals are black, shiny, and generally are a mediumrank coal. Bituminous coals generally have calorific values above 11,500 Btu/lb and volatile matter below 14% (ASTM, Jackson, 1997). In the Illinois Basin (and western Kentucky), however, the lower rank end of what are termed bituminous coals in the United States have calorific values of 11,100 to 11,300 Btu/lb.

Coal Rank
· The ASTM coal rank classifiion is based on a number of parameters obtained by various prescribed tests, which include calorific or heating value, volatile matter, moisture, ash, and fixed carbon (Figure ). Calorific or heating value of coal is defined as heat energy released as it undergoes complete combustion with oxygen. Volatile matter is released gas when coal is heated in .

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

coal rank and classifiion
Coal Classifiion. Coal is classified according to the nature of the original vegetation, the duration of its formation and – importantly – the depths and temperatures to which it has been subjected. There are several classifiions; we use the ASTM classifiion by rank, which is based on fixed carbon and gross calorific value.
