Addressing the Information Gaps on Prices of Minerals Sold …
There are two ways to express calorific value: gross calorific value or net calorific value. The GCV is the amount of heat liberated during a test in a laboratory, where the coal is combusted under standardised conditions at constant volume so that all of the water remains in liquid form. NCV is the maximum achievable heat in a boiler, because

Calorific Value
The calorific value of the fuel is the amount of heat or energy a fuel generates during complete combustion. It is the variable of the heat or energy released, which is either measured in Gross Calorific Value (GCV) or Net Calorific Value (NCV). The calorific value of a fuel can be determined using a bomb calorimeter.
