High fuel consumption. Jun 01, 2011· Re: High fuel consumption The difference between GCV and NCV looks ok as the South African coal haveing about 4 to 5 % hydrogen SO i feel there is no big differnce eg if coal having 45 % hydrogen then the heat taken by water for steam is ~ 236 Kcal/Kg, if South African coal of you specs (GCV=6206 Kcal/Kg) is taken for,..
Jan 01, 1983· A new formula for calculating the calorific value of coal from its ultimate analysis has been obtained by regression analysis of a data bank consisting of data on 775 samples of coals of all ranks. It yielded zero average difference between observed and calculated values and a standard deviation of 129 Btu/lb (300 kJ/kg).
Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called 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.
The gradation of noncoking coal is based on Gross Calorific Value (GCV), the gradation of coking coal is based on ash content and for semi coking /weakly coking coal it is based on ash plus moisture content, as in vogue as per notification.
