Please see below about how to calculate from gross asreceived to gross airdried and vice versa. GCV can be stated on a gross asreceived or gross airdried basis (gross asreceived = gar; gross airdried = gad). To summarize, the NCV is the "net energy" contained in coal that the power plant can use to generate electricity. The GCV is the ...

India, the world's third largest coal producing country, is expected to maintain strong dependency on coal for the coming few decades. The gross calorific value (GCV) of coal is a key yardstick for many end users purchasing coal from suppliers, as it provides a clear measure of the useful energy content of a coal. Several methods are available to predict GCV using either moisture content and ...
