US Coal in recent years has emerged as an excellent substitute to pet coke. Although substituting pet coke in any production facility requires the consideration of various aspects, US Coal has been found to be most compatible than other fuels.
The gradation of non-coking 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.

Dec 15, 2017· Net Calorific Value (NCV) also known as lower heating value (LHV) or lower calorific value (LCV) is determined by the subtracting the heat of vaporization of the water vapour from the higher heating value.This treats any H20 formed as a vapor. Natural gas prices are decided on the basis of GCV .

The energy value of coal, or the fuel content, is the amount of potential energy in coal that can be converted into actual heating ability. The value can be calculated and compared with different grades of coal or even other materials. Materials of different grades will .
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 U.S. 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).

This is because diluting GCV would allow uncrushed coal, including boulders, and other impurities to be supplied," the official said. The GCV system divides available coal into 17 grades, against seven in the UHV system, thereby forcing coal companies to maintain precise levels of quality in a given sample.
