The calorific value is the measurement of heat or energy produced, and is measured either as gross calorific value or net calorific value. The difference being the latent heat of condensation of the water vapour produced during the combustion process. Gross calorific value (GCV) assumes all vapour produced during the combustion process is fully condensed. Net calorific value (NCV) assumes the water leaves with the combustion products without fully being condensed.

GAR is ((100-total moisture)/ (100-inherent moisture)) x Calorific Value in ADB So all depends on the moisture. If we assumed total moist 25% and inherent 5% so the calorific value in ADB is (95%/75%) x GAR 3800 = 4800 Gross Calorific Value ADB So all depends on the moisture in the coal...

By Dulong formula
GCV, gross calorific value, is the quantity of heat produced by combustion. UHV, useful heat value, is the gradation of non-coking coal.
