Monitoring the sulfur content of coal | SpringerLink

May 13, 2016 · 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. Nuclear-physics methods are free of those problems.

Sulphur and coal - SourceWatch

Sulphur and coal. When coal is burned, it produces sulfur dioxide, the amount of which varies depending on the chemical composition and the concentration of sulfur in the coal. Compliance coal is coal which, when burned, emits 1.2 pounds or less of sulfur dioxide per million Btus and complies with the requirements of the Clean Air Act .".

Benefits of Burning PRB Coal - boilercleaning

The major benefit of PRB coal certainly is its low sulfur content, which automatically lower the sulfur oxide emission in power plants. PRB coal was essentially worthless until air pollution emissions from power plants became a concern. Then, the market for PRB coal surged because it is very low in sulfur.

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.

Carbon Dioxide Emission Factors for Coal

The amount of heat emitted during coal combustion depends largely on the amounts of carbon, hydrogen, and oxygen present in the coal and, to a lesser extent, on the sulfur content. Hence, the ratio of carbon to heat content depends on these heat-producing components of coal, and these components vary by coal rank.
