19 Facts About Bituminous coal

Bituminous coal, or black coal, is a type of coal containing a tar-like substance called bitumen or asphalt.

Bituminous coal is used primarily for electrical power generation and in the steel industry.

Bituminous coal is a particular rank of coal, as determined by the amount and type of carbon present in the coal and the amount of energy it can produce when burned.

The fixed carbon content refers to the percentage of the Bituminous coal that is neither moisture, nor ash, nor volatile matter.

An agglomerating Bituminous coal is a Bituminous coal that softens when heated, forming a hard, gray, porous coke that resists crushing.

Bituminous coal is used primarily for electrical power generation and in the manufacture of steel.

However, since single coals with all the necessary properties are scarce, coking coal is usually a blend of high-volatile bituminous coal with lesser amounts of medium- and low-volatile bituminous coal.

Smithing coal is bituminous coal of the highest quality, as free of ash and sulfur as possible, used to manufacture coke for use by blacksmiths.

Bituminous coal which lacks the qualities required for use as metallurgical coal is graded as thermal coal.

The Bituminous coal is first coked, removing volatiles, then steam treated to activate it.

However, the increase in rank of maturing Bituminous coal mostly reflects the maximum temperature the Bituminous coal reaches.

The Appalachian Bituminous coal is notably low in sulfur and is often of metallurgical grade, while the Interior Province Bituminous coal is much higher in sulfur.

Belt of Carboniferous coal fields extends into central Europe, and much of this is bituminous coal.

Bituminous coal fields are found in Poland and the Czech Republic, and the Polish deposits are one of the most important of that nation's natural resources.

Second peak in coal deposition began in the Cretaceous, though most of this is lower rank coal rather than bituminous.

In Canada, the Western Canada Sedimentary Basin of Alberta and British Columbia hosts major deposits of bituminous coal that formed in swamps along the western margin of the Western Interior Seaway.

Bituminous coal was once extensively used for home heating in the US.

Bituminous coal quality is improved with floatation methods, which increase the fraction of vitrinite to yield a cleaner-burning product.
