Depending on the coal rank, there may be systematic differences between the results obtained by drying in the different atmospheres on subsamples of the same sample. Drying in a nitrogen atmosphere is suitable for all hard coals, while drying in air is only suitable for hard coals not susceptible to oxidation.

Moisture Correction for Coal Analysis

Moisture in coal varies from the point where it is received to the point where it enters the boiler. The variation in the moisture affects the reported heating value and analysis. The laboratory analysis is required to be corrected to the actual moisture content in the field. Methods for applying these corrections are explained here.
