Sub-bituminous coals may be dull, dark brown to black, soft and crumbly at the lower end of the range, to bright jet-black, hard, and relatively strong at the upper end. They contain 15-30% inherent moisture by weight and are non-coking (undergo little swelling upon heating). The heat content of sub-bituminous coals range from 8300 to 11,500 BTu/lb or 19.3 to 26.7 MJ/kg. Their relatively low density and high water content renders some types of sub-bituminous coals susce…

Sub-bituminous coal is a lower grade of coal that contains 35–45% carbon. The properties of this type are between those of lignite, the lowest grade of coal, and those of bituminous coal, the second-highest grade of coal. Sub-bituminous coal is primarily used as a fuel for steam-electric power generation

Sub-Bituminous Coal. Sub bituminous coal is lignite that has been subjected to an increased level of organic metamorphism. This metamorphism has driven off some of the oxygen and hydrogen in the coal. That loss produces coal with higher carbon content up to 71% to 77% on a dry ash-free basis. Contact us.

The normal range for sulphur content in sub-bituminous coal is between 0.5 to 0.8 percent. The coal with less than 1% sulphur is classified as low-sulphur coal. Coal with 1% to < 3% sulphur is medium-sulphur coal. The content of sulphur in coal affects the combustion product which is the fly ash behaviour.

Bituminous coal is an organic sedimentary rock formed by diagenetic and sub metamorphic compression of peat bog material. Its primary constituents are macerals: vitrinite, and liptinite. The carbon content of bituminous coal is around 45–86%; the rest is composed of water, air, hydrogen, and sulfur, which have not been driven off from the ...
