Abstract. In India, coal-based electricity is a leading cause for greenhouse gas emissions. However, many uncertainties prevail in the emissions estimation from coal-fired plants due to the dynamics of varying net calorific values (NCV) and carbon emission factors (CEF) associated with different grades of coal coupled with the coal oxidation …

Grade Specification. The Quality (Grade) of coal (Non-coking) will be specified as follows. GCV Grades. GCV BAND (K.Cal./Kg.) G1. Exceeding 7000. G2. Exceeding 6700 and not exceeding 7000. G3.
Coal and Related Coal Products Frequently Asked ... - Flamite. No coal is graded according to its energy content (CV) as well as its size. An A grade coal has a CV higher than 27,5 MJ/kg, a B grade between 26,5 -27,5 MJ/kg, a C grade between 25,5 – 26,5 MJ/kg etc. A common misconception occurs when people discuss "export quality coal".
India, the world's third largest coal producing country, is expected to maintain strong dependency on coal for the coming few decades. The gross calorific value (GCV) of coal is a key yardstick for many end users purchasing coal from suppliers, as it provides a clear measure of the useful energy content of a coal.
