The Moisture in the Coal is both these put together and is the "Total Moisture." A coal sampled at the mines having a moisture of 20%, after storage for a few weeks, when entering the boiler can have moisture of only 8%. If the Coal sampled at the mines has an HHV of 18800 kJ/kg the same coal at the boiler will have a higher HHV.
Net calorific value (NCV) can be calculated from gross calorific value (GCV) of coal using the formula: NCV = GCV - (0.09 * moisture content) for lignite and sub-bituminous coals, or NCV = GCV ...
