What is the difference between gross and net calorific ...

2021-6-23 · Calorific value represents the amount of heat or energy in a given volume of gas. An average calorific value is calculated monthly by the transporter and allows for any periodic or regional variations in the quality of natural gas. Gross Calorific Value (GCV) is the amount of heat released by the complete combustion of a unit of natural gas.
