2020327;In India utilities usually get coal from multiple sources and coal is priced essentially on the basis of gross calorific value (GCV). During combustion, GCV contributes only to the maximum possible heat release, though heat release rate is mostly controlled by coal proximate parameters i.e. ash, volatile matter, moisture and fixed carbon

GCV (Gross Calorific Value) and NCV (Net Calorific Value) are both measures of the amount of energy released when a fuel is burned. The main difference between the two is that GCV includes the latent heat of vaporization of water in the combustion products, while NCV does not. This means that NCV provides a more accurate representation of the
