Gross calorific value to define coal pricing. Coal India Ltd, a Maharatna company, is set to usher in a new era of pricing by benchmarking coal on the basis of its gross calorific value (GCV) from the 2012 calendar year. However, the transition to GCV pricing would be in phases, to assist sectors having huge discounts now.

Determining the Gross Calorific Value in Coal. Coal, as it is commonly known, is a solid fossil hydrocarbon fuel material.

Multiple linear regression (MLR) method is used to develop these models. In the first model, different properties of coal such as ash, moisture, and volatile matter contents are correlated with the GCV. Whereas in the second model, the GCV is predicted from the maximum absorption band depth at five different wavelength ranges.
