of the water vapour produced during the combustion process. Gross calorific value (GCV) assumes all vapour produced during the combustion process is fully condensed. Net calorific value (NCV) assumes the water leaves with the combustion products without fully being condensed. Fuels should be compared based on the net calorific value.

about 5% less than the gross calorific value (GCV) i.e. higher heating value (HHV) for solid and liquid fuels, while for gaseous fuels, the NCV is about 10% less. Default conversion factors i.e. NCV and emission factors (on a net calorific basis) are available for a list of default fuels as defined in the 2006 IPCC Guidelines.

The difference between net and gross as received (NAR v/s GAR) specific energy values is the latent heat of the water vapor which lowers the effective calorific value in the boiler.

2. Net calorific value (NCV) or Lower calorific value (LCV): NCV is defined as the amount of heat produced when a unit amount of a fuel is burnt completely in air and products of combustion are allowed to escape. NCV = GCV – Latent heat of water vapour formed = GCV – Mass of hydrogen × 9 × Latent heat of steam

The equations to convert from HHV to GCV as well as to convert from HHV to NCV or. NHV are given in equations 3, 4 and 5. 3. CONCLUSION.

Since water releases heat when it condenses, GCV is clearly bigger than NCV. Is GCV higher than NCV? How do you convert NCV to GCV? = 32060.2 KJ/Kg NCV = GCV – 24.44(9×%H + %M) = 30630.26 KJ/Kg Thus NCV = 0.955 times GCV in this case. What's the difference between GCV and UHV grades?
