Net Caloric Value (NCV) represents the amount of usable energy in a fuel after subtracting the energy lost in vaporizing water contained in the fuel and in the combustion products. Gross Caloric Value (GCV), in contrast, is the …

Calorific value is the heat energy released per unit mass of fuel burned as shown by Formula F7.1. Gross calorific value, or higher heating value (HHV), is the total heat released making no allowance for the latent heat required to vaporize the liquid water produced by the combustion process.Hence it is a theoretical parameter and is rarely used. The net calorific value, or lower …

The NCV values of coal are derived from experimentally determined Gross Calorific Value (GCV) and the available hydrogen content of coal using the formula [2], [20]: (2) NCV = GCV-53 H where H is the available hydrogen content of coal which accounts for the total hydrogen including those associated with the moisture.

The gradation of non-coking coal is based on Gross Calorific Value (GCV), the gradation of coking coal is based on ash content and for semi coking /weakly coking coal it is based on ash plus moisture content, as in vogue as per notification. ... GCV BAND (K.Cal./Kg.) GRADE: Exceeding 7000: G-1: Exceeding 6700 and not exceeding 7000: G-2 ...

The calorific value defines the energetic content of the materials; it is the amount of heat a substance produces after complete combustion. You can express it as the gross calorific value (GCV) or high heating value. Also, the calorific value of a substance (generally, solid biofuel or food) is the specific energy of combustion for a unit mass.

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.

NCV is derived from the GCV by deducting the latent heat of vaporization of water present and formed. Thus, NCV (MJ/kg.) = GCV (MJ/kg.) − 0.222 (% H) . . .

you need to convert the volume of the fuel into a mass – or have the NCV expressed in terms of volume. Usually, a step will be required to convert mass into volume and this is done by using a conversion parameter known as density that expresses the mass per a unit of volume (e.g. kg/m3). You can find some density values in Table 2, below.
