GCV is coal's most influential rank property and depends on the composition of minerals and maceral [6]. The most exact measurement is GCV generated from a coal sample in a laboratory using an adiabatic bomb calorimeter, but the process is expensive, time-consuming, and tedious [4, 7]. These limitations forced the formulation of different ...

Coal Specifications. We exclusively trade thermal coal of Indonesian origin and offer three main calorific values – GAR 4200 kcal/kg, NAR 4700 kcal/kg and NAR 5500 kcal/kg. The table below indicates the typical specifications of each category of coal under the American Society for Testing and Materials Standard. Specification in ASTM Standard.

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. Is Gar and GCV same?
