In addition to its direct use for combustion, coal can be converted to organic gases and liquids, thus allowing the continued use of conventional oil and gasfired processes when oil and gas supplies are not available. Currently, there is little commercial coal conversion in the United States.

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 ...

Isothermal gasification profiles of both samples were analysed under CO 2, N 2 /CO 2, and N 2 /dry air respectively.. N 2 /dry air experiments resulted in observation of additional combustion reactions before the coal gasification step.. Gasification reactivity of the washed and dried coal sample was found to be higher than that of as received coal sample.

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.
