The gross calorific value (GCV) of coal is a key yardstick for many end users pur chasing coal fr om suppliers, as it pr ovides a clear measure of the useful energy content of a coal. ... here to the full data set and for each of the sample subsets from the individual coal basins. It is also applied to the separate 200-coal-sample data set ...
The GCV of a coal sample is measured experimentally using a Bomb calorimeter. Since GCV is a major indicator of the quality of coal, a number of linear correlations have been developed for its prediction on the basis of proximate and/or ultimate analyses. ... Thus, Chaudhury and Biswas [7] proposed a correlation, which is a modified …
Properties of US coal were studied for the prediction of gross calorific value (GCV).. Random forest (RF) models indicated that RF can accurately predict GCV. • RF models are much suitable to assess complicated relationships in coal processing.. Results recommended random forest as a model can be applied for other coal resources.
1.. IntroductionCalorific 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 …
station as 0.2 % of the coal quantity and that of non-pit head station as 0.8 % of the coal quantity can be considered. However, these losses are pertaining to the quantity of the coal and does not have any impact on the GCV of the coal. 3. GCV of the coal is decreased over a period as a result of the storage in the coal yard.
