Moisture Correction for Coal Analysis - Bright Hub Engineering

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.
