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.
