Moisture Correction for Coal Analysis

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. This is because the percentage of combustibles in one kg is more. Based on a simple proportion calculation, multiplying by a factor [100-8]/ [100-20] the HHV will be 21620 kJ/kg. In real life, Coal analysis takes place in the laboratory.
