Abstract. Information regarding the sulfur content of the coal is required not only in metallurgy but also when burning coal as a fuel. The traditional method of determining the sulfur content of coal is unsuitable for large-scale monitoring of processes because it is laborious and not sufficiently reliable.

The coal's sulfur content is generally less than 2 percent by weight. Nitrogen makes up approximately 0.5 to 2 percent of the coal's weight. Sub-bituminous coal typically is found near the surface, which results in lower mining costs, making it a relatively inexpensive coal.
1.1 Bituminous And Subbituminous Coal Combustion
Although subbituminous coal has lower calorific values than bituminous coal, its sulfur content is often low, sometimes less than 1 percent. Since subbituminous coal has a much lower calorific value than the same amount of a bituminous coal, more subbituminous coal must be burned to obtain the same amount of energy.

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 60–80%; the rest is composed of water, air, hydrogen, and sulfur, which have not been driven off from the ...
