gross calorific value (GCV) of a sample can be determined from its elemental composition (Buckley and Domalski, 1988). By the year of 1980 at least 9 different formulas for calculating GCV from the ultimate analysis and 11 formulas for calculating GCV from the proximate analysis have been developed (Mason and Gandhi, 1980).

Determining the Gross Calorific Value in Coal

Determining the Gross Calorific Value in Coal. Coal, as it is commonly known, is a solid fossil hydrocarbon fuel material. The gross calorific value of coal is frequently used when determining the total calorific value for a specific amount of coal for fuel value purposes or when establishing the rank of classification of the coal material.

Kirkwood's proposal for the geometric coefficient of variation (GCV) is not generally used. Instead, the accepted definition of the GCV is GCV = sqrt(exp(σ 2) – 1), which is the definition that is used in SAS. The estimate for the GCV is sqrt(exp(s 2) – 1). You can use these formulas to compute the geometric statistics for any positive data.
