WebHeating value or calorific value of a coal is defined as the amount of heat evolved when a unit weight of coal is burnt completely. It may be reported on two bases, the higher heating value (HHV) or gross calorific value (GCV) and the lower heat-ing value (LHV) or net calorific value (NCV). The GCV refers to the heat released from the fuel WebGCV=12.51%), panicle length (PCV=10.98%, GCV=10.47%) and spikelet per panicle (PCV=18.64%, GCV=18.55%). have expressed low estimates (<10%) of coefficient of variation for both the parameters.
