General. The [GLOSS]calorific value [/GLOSS] of a fuel may be expressed either as the Higher (HCV) or Lower Calorific Value (LCV). The terms "Higher" and …
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.
Referencing the boiler efficiency to GCV gives a more accurate picture of the efficiency as it takes into account all the energy contained in fuel and draws our attention to the enthalpy loss. We can thus take corrective action. Illustration: Consider a 10TPH, 10.5 Kg/cm2 boiler with feedwater temperature of 90degC and S: F ratio of 14.

To calculate GCV of fuel we use the formula as follows:-GCV of Fuel = QC*(%C/100)+ QS*(%S/100) + QH*2*(%H/2) -[2*(%O/32)]/100. GCV of fuel = 8137.5*(86.5/100)+ …
The Gross Calorific Value (GCV) of a fuel is defined on the basis that all of the water vapor produced by the complete combustion of the fuel is subsequently converted into the liquid state. The Net Calorific Value (NCV) of a fuel is defined on the basis that all of the water vapor produced by combustion of fuel remains in the vapor state.

Table 1 Proximate Analysis of Syrian petcoke, air-dried basis. The gross calorific value (GCV) for the different types of Syrian coke varied between 34.3×10 3 and 35.1×10 3 kJ/kg, with an average value of 34.8×10 3 kJ/kg ( Table 1 ). The difference between the maximum and minimum values amounted to 2.3% of the average value.

Value (NCV), it is assumed that the products of combustion contained the water vapor and that the heat in the water vapor is not recovered. In other words, the 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) . . . (4.1)

According to the Energy Statistics Manual, "energy content of solid and liquid fossil fuels, and of renewables and wastes is expressed in net calorific value (NCV). Energy content of natural gas and manufactured gases is expressed in gross calorific value (GCV)". For gases, these values are converted to NCV in the balance tables.
