Coal assay - Wikipedia

The particle size distribution of milled coal depends partly on the rank of the coal, which determines its brittleness, and on the handling, crushing and milling it has undergone. Generally coal is utilised in furnaces and coking ovens at a certain size, so the crushability of the coal must be determined and its behaviour quantified.

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 when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Low rank coal comprises sub-bituminous coal, lignite and brown coal, all of which contain substantial amounts of water (20% to 70% Total Moisture (“TM%”) by weight). Due to its high moisture content, low rank coal diminishes power plant efficiency and produces more emissions per unit of energy produced.
