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.
