Moisture Correction for Coal Analysis

Wet and Dry Basis. There are two conventions for measuring qualities of biofuel per kg, such as calorific value, these are referred to as the wet and dry basis. The following equations show the difference between the wet and dry basis:

Dry, mineral matter-free basis: Data or results are calculated to a theoretical base as if there were no moisture or mineral matter in the coal sample (ASTM method D388-12; American Society for Testing and Materials, 2013, p. 390–396). For this basis, a calculation is needed to determine mineral-matter content rather than ash yield.
