(GCV), or higher heating value, measures the total (maximum) amount of heat that is produced by combustion, including latent heat before combustion or generated in the combustion process. The net calorific value (NCV), or lower heating value, ex-cludes this latent heat. Natural gas in international trade is usually measured on

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.

Chemical composition of the coal is defined in terms of its proximate and ultimate (elemental) analysis. The parameters of proximate analysis are moisture, volatile matter, ash, and fixed carbon. Elemental or Ultimate analysis encompasses the quantitative determination of carbon, hydrogen, nitrogen, sulfur, and oxygen. The calorific value Q, of coal is the heat liberated by its complete ...

Mar 01, 2020· Previous studies of the authors [16,17] reported the GCV and net calorific value (NCV), VM, FC, and A content of bamboo using FT-NIR spectroscopy, and focused on the sample homogeneity of ground bamboo samples with particle size ≤ 3 mm. The GCV, NCV, VM, FC, and A resulted in R 2 values of 0.92, 0.93, 0.82, 0.85, and 0.51, respectively. The ...

proximate values, ultimate values, calorific value and HGI. Calorific Value (CV) is an important thermal property of coal which indicates the amount of heat energy that could be liberated on combustion of a specific quantity. The other important thermal properties of coal are plastic, agglutinating and agglomerating indices.

Heating value or calorific value of a coal is defined as the amount of heat evolved when a unit weight of coal is burnt completely. It may be reported on two bases, the higher heating value (HHV) or gross calorific value (GCV) and the lower heat-ing value (LHV) or net calorific value (NCV). The GCV refers to the heat released from the fuel

95 per cent of the gross calorific value (GCV) for liquid fossil, solid fossil and biomass fuels, and 90 per cent of the GCV for natural gas. For other fuels, you should determine if the figures have been derived using the net or gross calorific values and make the conversion to NCV if necessary.
