A fuel's GCV counts all its chemical energy but its NCV disregards that fraction (10% in the case of natural gas) that will be absorbed as latent heat. So when you calculate efficiency on the basis of NCV you get a higher value than if you had used GCV, to the extent that you see condensing boilers advertised as having over efficiency.

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 subtracting the heat of vaporization of the water vapour from the higher heating value. This treats any H 2 0 formed as a vapor. Natural gas prices are decided on the basis of GCV and NCV.
higher heating value (HHV) aka gross calorific value (GCV) lower heating value (LHV) aka net calorific value (NCV) Note that I use HHV/GCV and LHV/NCV interchangeably as they are in industry. Figure 1 – A fire-tube shell boiler. These conventions arise from a practical engineering reality. It's about the water vapour produced during combustion.

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 . Where fuel characteristics (moisture, hydrogen and oxygen contents) are known, the 2006 IPCC Guidelines give a more precise method to convert GCV to NCV data: NCV = GCV − 0.212H − 0.0245M − 0.008Y. M – Moisture, H

Answer (1 of 2): When water as one of the combustion products remains in the liquid state. When the water produced is in the gaseous state it means that some amount of the energy of combustion was used to vapourize water and hence in this case the caloric value is called net calorific value which...

NCV (net calorific value) is the quantity of heat produced by combustion when the water produced by combustion remains gaseous. Since water releases heat when it condenses, GCV is clearly bigger than NCV. GCV is also called HHV (higher heating value); NCV is also called LHV (lower heating value.) 70 2 2 Vivek B
GCV is calculated on the basis of a high-precision measurement of the resulting temperature increase. Calculating NCV involves measuring the hydrogen content of the fuel. The moisture level in the sample is also measured in order to express the results in megajoules per kilogram on a dry basis (MJ/kg dry) and megajoules per kilogram as received ...

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 Gross Calorific Value (GCV), also called High Heating Value (HHV) The Net Calorific Value (NCV), also called the Low Heating Value (LHV) The functional relation between NCV and GCV is: NCV = GCV – (MASS OF WATER * 2.4425) -
GCV = NCV + 584 ((9H 2 % + M%) / 100) Where, GCV= Gross calorific value of fuel, kcal/kg NCV = Net calorific value of fuel, kcal/kg H 2 %= Hydrogen % by weight present in the fuel M% = Moisture % by weight present in the fuel 584 = Latent heat corresponding to partial pressure of water vapour, kCal/kg
NCV = GCV – (MASS OF WATER * 2.4425) - Mass of water (in kg) generated by one kg of fuel during the combustion process. 9H + x H2O Mass of water = -----100 H weight percent of Hydrogen in the fuel xH2O weight percent of water in the fuel. 2. Clever method ...
