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. The coal is spread out and air-dried to remove most of the surface moisture. The Coal Analysis and Calorific Value is determined and reported as on Air Dried Basis (ADB).

ADB – Air-Dried Basis. In coal sample analysis, ADB neglects the presence of moistures other than inherent moisture while DB (dry-basis) leaves out all moistures, including surface moisture, inherent moisture, and other moistures. ARB – As-Received Basis. It provides a rough estimate of the heating value of coal.
