Bituminous coal has a greater range of sulfur content. The other half of coal plants use subbituminous coal, which is mostly produced in western states such as Wyoming and generally has a lower sulfur content than most bituminous coals. Less than 5% of operating coal capacity uses lignite or other coal .

Coal - Energy Education

Coal is a rock formed from the decomposition of plant life. It is primarily composed of carbon, with many other trace elements. Coal's high energy density and extensive reserves found in nature make it useful as a fuel for electricity generation in coal-fired power plants, and in some places, heating.

How is coal formed?

In the process of transformation (coalification), peat is altered to lignite, lignite is altered to sub-bituminous, sub-bituminous coal is altered to bituminous coal, and bituminous coal is altered to anthracite. Lignite - is the lowest rank of coal - which means that it has the lowest heating value and lowest carbon content. Although lignite is more solid than peat it crumbles when shipped long distances.

Coal - Simple English Wikipedia, the free encyclopedia

Bituminous coal is a dense rock, black but sometimes dark brown. It is a relatively soft coal that breaks and burns readily and quickly. It used as fuel in power stations, and for heat and power applications in manufacturing, for blacksmithing; and to make coke. Steam coal was once widely used as a fuel for steam locomotives.

Feb 27, 2013 · Bituminous coal is a higher rank of coal above lignite (although there is a transitional rank called sub-bituminous coal). Bituminous coals tend to break and weather in a blocky fashion, are relatively sooty to the touch, and are harder & heavier than lignite (but still relatively soft & lightweight). Slightly discernible plant fossil fragments may be present on bituminous coal bedding planes.

Bituminous Coal - an overview | ScienceDirect Topics

In bituminous coals, specific plant components in the coal (macerals) become more homogenous, and the cell structures of woody material within the coal (still visible in lignite and subbituminous coals using scanning electron microscopy) become significantly deformed (Hatcher et al., 1994; Hatcher and Clifford, 1997). As a result of these physical changes during late-stage coalification, the appearance of coal .

Bituminous coal. Its primary constituents are macerals: vitrinite, and liptinite. The carbon content of bituminous coal is around 60–80%; the rest is composed of water, air, hydrogen, and sulfur, which have not been driven off from the macerals. Bank density is approximately 1346 kg/m³ (84 lb/ft³).

Coal Basics What is coal? Coal is a solid fossil hydrocarbon that represents the storage of solar energy from the past in the form of preserved plant material. The plants during the preservation process have been broken down into organic matter that comprises moisture, ash, volatile matter (gases and liquids given off on heating) and fixed carbon.
