Estimation of gross calorific value based on coal analysis

01/07/20091. Introduction. Calorific value is an important property, indicating the useful energy content of coal and, thereby, its value as fuel. Heating value is a rank parameter, but is also dependant on the maceral and mineral composition (Hower and Eble, 1996).A number of equations have been developed for the prediction of gross calorific value (GCV) based on proximate and / or ultimate analyses

net calorific value

Solid biomass fuels are more costly than coal, oil, and natural gas, even when compared on a simple gross calorific value (GCV) or net calorific value (NCV) basis. The cost disadvantage of solid biofuels is accentuated by the lower comparative efficiency of use in power generation, in synthesis gas production, and in direct heating systems.
