Quality Of Coal

From 01.01.1985, coal was graded as A to G (Seven grades) basing on the Useful Heat Value.

As per GoI Notification, from 01.01.2012 onwards coal is being graded on Gross Calorific Value (GCV). There are 17 GCV grades starting from 2201K.Cal/Kg (G17) to above 7000K.Cal/Kg (G1). GCV bandwidth between two successive grades is 300 K.Cal/Kg.
