Relationship between proximate analysis parameters and combustion
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 ...

What is the difference between GCV and NCV?
What is the difference between GCV and NCV? Gross Calorific Value (GCV) is the amount of heat released by the complete combustion of a unit of natural gas. Net Calorific Value (NCV) also known as lower heating value (LHV) or lower calorific value (LCV) is determined by subtracting the heat of vaporization of the water vapour from the higher ...
