Chemical properties of coal. Coal comes in four main types or ranks: lignite or brown coal, bituminous coal or black coal, anthracite and graphite.Each type of coal has a certain set of physical parameters which are mostly controlled by moisture, volatile content (in terms of aliphatic or aromatic hydrocarbons) and carbon content..

RESULT FROM CALCULATION Result derived from the above formulas for the fuel Indian lignite coal with GCV of 4300 kcal/kg and semi bituminous coal with GCV of 5800 kcal/kg is shown in table 1 and 2.Coal Basics Coal Marketing International,Coal Basics What is coal? Coal is a solid fossil hydrocarbon that represents the storage of solar energy from the past in the form of preserved plant material. The plants during the preservation process have been broken down into organic matter that comprises moisture, ash, volatile matter (gases and liquids given off on heating) and fixed carbon.
OF THE EFFECT OF COAL BLENDING ON HARDGROVE GRINDABILITY INDEX Niaz Muhammad Shahani . the GCV also exhibits inverse relationship while ash and fixed carbon reveal direct including particulars of moisture, ash, volatile matter and fixed carbon. In addition to that,A Discussion on Non-coking Coal Pricing Systems Adopted in,combustible impurities and is represented essentially by its ash content. Ash is the solid incombustible residue obtained after burning the coal. Moisture content is another negative quality parameter of coal. It could be either inherently present in coal or could get added during mining, cleaning, transport, stock-piling, etc. Coal
