A known mass of the material is dried and the loss of mass calculated as moisture. The moisture may be determined either by drying in one stage at 108 ±2°C or by a two-stage process in which the sample is first air dried under atmospheric conditions and the remaining moisture removed by drying in an oven at 108 ±2°C.

estimates GCV based on moisture and ash data, was provided by Mazumdar (1954) (Eq.1): GCV= 85.6{100-(1.1 A + M)} – 60 M (1) Where A is ash yield; and, M is moisture content. Both A and M are measured at 60% relative humidity and 40 °C. This GCV prediction formula has been widely applied by some end user industries in India (Dey et al., 2012).
