Kentucky coal is improved by the partial removal of the impurities—sulfur and ash. The ... 0.5% to 2.5% can be subtracted from the average sulfur content and 9% to 13% can be subtracted from the ash content after the coal washing process. In Eastern Kentucky, coals with very high ash contents are washed. High ash content results from seam ...

Oct 07, 2019· Knowledge of the total sulfur content in a combusted coal is also important because sulfur can lead to fouling and corrosion in boilers. In the steel industry, low-sulfur coals are used for coking. In general, total sulfur contents less than 0.8 percent (air-dried basis) are used to make coke for steel (Stach and others, 1982; Thomas, 1992 ...

The Clintwood coal bed is the stratigraphically lowest coal bed mined throughout the coal field. In Whitley County, the sulfur content increase from 0.6% at the base to nearly 12% in the top lithotype. Pyrite in the high-sulfur lithotype is a complex mixture of sub- to few-micron syngenetic forms and massive epigenetic growths.
