Higher Calorific Value (HCV) or Gross Calorific Value (GCV): This value includes the heat released when the water vapor produced during combustion is in a liquid state. It accounts for the total energy released, including the latent heat of vaporization of water. Lower Calorific Value (LCV) or Net Calorific Value (NCV):

GCV is clearly greater than NCV since water releases heat when it condenses. LPG vs Natural GasSummary of Key Differences. Because LPG has a higher calorific value (energy content), it takes less gas to generate the same amount of heat. The oxygen-to-gas ratio required for successful combustion is the second significant difference.

What is the relation between GCV and NCV? for coal and oil, the NCV is about 5 % less than the GCV. for most natural and manufactured gas, the NCV is about 10 % less. Why is GCV higher than NCV? This is because,NCV (net calorific value) is the quantity of heat produced by combustion when the water produced by combustion …

NCV is generally reported on an 'as received' basis. NCV determined by constant volume delivers a slightly higher result than NCV performed under constant pressure. Compared to the GCV (as received), NCV (ar) better represents the practical energy of a coal for a power station, and is a common parameter for thermal coal sale contracts.
