All sub-bituminous coal (38 percent of the demonstrated reserve base) is west of the Mississippi, with most of it in Montana and Wyoming Lignite: This coal's brownish-black color has a high moisture content and is the lowest rank coal It is often called "brown coal" and is used almost entirely as fuel for steam-electric power generation.

The chemical forms of sulfur in coal: a review William H Calkins Department of Chemical Engineering, University of Delaware, Newark, DE 19716, USA (Received 25 May 1993) The sulfur in coal exists in inorganic and organic forms The inorganic forms are usually sulfides and sulfates, with pyrite the major inorganic sulfur contaminant in most coals.

Moisture absorbs heat, so high moisture content in coal reduces the relative efficiency of heating when a coal is combusted This is why low-rank, high-moisture coals have lower calorific values (Btu/lb) than high-rank, low-moisture coals.

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seamsCoal 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.
