Relationship between GCV and NCV based on the ultimate analysis is given by the equation 'NCV in kcal/kg = GCV – 50.6*%H – 5.85*%M – 0.191*%O where H, M, O are the values of H2, moisture, and O2 of the coal. The CV of the coal can be determined either by calculation from chemical analysis or by burning a sample in calorimeter.

The given values are for fuels with the given density. The variation in quality may give heating values within a range 5 -10% higher and lower than the given value. Also the solid fuels will have a similar quality variation for the different classes of fuel. 1 Btu (IT)/lb = 2.3278 MJ/t = 2327.8 J/kg = 0.55598 kcal/kg = 0.000646 kWh/kg.

Conversion of GCV to NCV can be done with below formula :- GCV = NCV + 584 ( (9*H2%+M%)/100) Where, GCV, Gross calorific value of fuel, Kcal/Kg NCV, Net Calorific Value of fuel, Kcal/Kg H2%, Hydrogen Percentage by Weight in the fuel M%, Moisture percentage by weight in the fuel

Coal Grades. 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. Grades of Coking Coal. Grade. Ash Content. Steel Grade - I. Not exceeding 15%.

GCV [Gross Calorific Value] Amount of heat evolved by complete combustion of unit mass when the products of combustion are cooled down to the initial atmospheric temp. i.e. 15 deg.C. On burning a fuel, hydrogen present in it combines with oxygen and steam is formed. this steam carries certain heat besides the dry hot flue gases.

The Net Calorific Value (NCV) of a fuel is defined on the basis that all of the water vapor produced by combustion of fuel remains in the vapor state. Enthalpy loss – i.e. the loss in boiler efficiency due to converting the inherent moisture in fuel to vapor is not captured when the NCV is used calculate the boiler efficiency.
