What is the difference between gross and net calorific

Dec 15 2017 0183 32 Gross calorific value GCV is the amount of heat released by the complete combustion of a unit of natural gas It is also known as Higher Heating Value HCV Net Calorific Value NCV also known as lower heating value LHV or lower calorific value LCV is determined by the subtracting the heat of vaporization of the water vapour from the higher heating valueThis treats any H20 formed as a...
