What is the difference between GCV and UHV of coal?
In GCV ( Gross calorific Value) it is asumed that moisture & other elements present in coal (besides coal) can be used for generation of Heat and hence ' gross'. While in UHV ( useful heat value) it is assumed that those elements cant produce heat and so are eleminated for the purpose of heat calculation.

Predictions of Gross Calorific Value of Indian Coals from …
estimates GCV based on moisture and ash data, was provided by Mazumdar (1954) (Eq.1): GCV= 85.6{100-(1.1 A + M)} – 60 M (1) Where A is ash yield; and, M is moisture content. Both A and M are measured at 60% relative humidity and 40 °C. This GCV prediction formula has been widely applied by some end user industries in India (Dey et al., 2012).
