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.

Nov 17 2012 · The coal that is passing through a pulverizer is entrained by the use of hot air usually from the air heater During the pulverization process the surface area of the coal particles increases dramatically exposing fresh coal to the entrainment air The inherent and surface moisture of the coal is reduced by the exposure to hot air
