It is a variable that represents the amount of heat or energy released and is measured in Gross Calorific Value (GCV) or Net Calorific Value (NCV) (NCV). A bomb calorimeter can be used to determine the calorific value of a fuel. We may express the calorific value formula as follows using the preceding understanding of calorific value:

The GCV, which is defined as the amount of heat evolved when a unit weight of coal is entirely burned, indicates the useful energy content of coal (Patel et al. Citation 2007). A greater GCV indicates that less coal is needed to produce one unit of electricity (Mahapatra Citation 2016). Therefore, the GCV provides an estimation of the plant's ...

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.

Similar to GCV, NCV is typically measured in units of kilojoules per kilogram (kJ/kg) or British thermal units per pound (BTU/lb). NCV is particularly useful in applications where the heat generated is not fully utilized, such as in open fires or certain heating systems. By excluding the latent heat of vaporization, NCV provides a more ...

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.
