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.
