The Xcel Energy (formerly Northern States Power) Sherco Plant, located in Becker, Minn., is a coal-fired facility that burns a low-sulfur, sub-bituminous coal from Wyoming and Montana. This plant, Xcel's largest, was the site were the wet precipitator process within a scrubber system was pioneered a process that removes more particles and .
Subbituminous coal, generally dark brown to black coal, intermediate in rank between lignite and bituminous coal according to the coal classification used in the United States and Canada. In many countries subbituminous coal is considered to be a brown coal. Subbituminous coal contains 42 to 52
Burning Coal Beginning in late 1979 the word coal started to again become popular with consumers. Rumors that we would run out of wood and those saying that we have an almost inexhaustible supply of coal probably had something to do with it.
The coal is slow-burning and difficult to ignite because of its high density, so few pulverized, coal-fired plants burn it. Heating Value . Anthracite burns the hottest among coal types (roughly 900 degrees or higher) and typically produces approximately 13,000 to 15,000 Btu per pound. Waste coal discarded during anthracite mining, called culm ...

Mar 15, 2019· Sub-bituminous coal is considered black coal, even though its appearance varies from bright black to dull dark brown. Its consistency ranges from hard and strong to soft and brittle due to its intermediate stage—between bituminous and brown coal (lignite). The coal is widely used for generating steam power and industrial purposes.

With only half the volatile matter content of bituminous coals, burning produces less smoke; hence, it is sometimes called smokeless coal. Subbituminous coal, such as that found in the western United States, is high in moisture when mined and tends to break up as it dries or is exposed to the weather; it is likely to ignite spontaneously when ...
Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or asphalt. It is of higher quality than lignite coal but of poorer quality than anthracite. Formation is usually the result of high pressure being exerted on lignite.

Dec 15, 2017· Coal itself has a wide variation in properties, and can be categorized into four main types, or ranks—lignite, sub-bituminous, bituminous, and anthracite—in order of increasing carbon and energy content. Most of the coal burned in US power plants is bituminous or subbituminous coal.
subbituminous coal when it burns. Coal - Wikipedia. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams.
The higher the number of BTUs, the more heat is produced. Lignite has a lower BTU level than any other type of coal; therefore, it burns faster and contains less heat energy than harder coals (anthracite, bituminous, and subbituminous).
A major source of sub-bituminous coal in the United States is the Powder River Basin in Wyoming. Current use. Sub-bituminous coals, in the United States, typically have a sulfur content less than 1% by weight, which makes them an attractive choice for power plants to reduce SO 2 emissions under the Acid Rain Program.
