The proximate analysis of a coal determines the moisture content, volatile matter (VM), ash and, by difference, the fixed carbon within the coal sample. It is the simplest and most common form of coal evaluation, and constitutes the basis of many coal purchasing and performance prediction indices used by utility operators.

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.

The calorific value of the fuel is the amount of heat or energy a fuel generates during complete combustion. It is the variable of the heat or energy released, which is either measured in Gross Calorific Value (GCV) or Net Calorific Value (NCV). The calorific value of a fuel can be determined using a bomb calorimeter.
