Fuels - Higher and Lower Calorific Values

The given values are for fuels with the given density. The variation in quality may give heating values within a range 5 -10% higher and lower than the given value. Also the solid fuels will have a similar quality variation for the different classes of fuel. 1 Btu (IT)/lb = 2.3278 MJ/t = 2327.8 J/kg = 0.55598 kcal/kg = 0.000646 kWh/kg.

Gross Calorific Value - an overview | ScienceDirect Topics

Since 1961, the average gross calorific value of the domestic thermal coal supply has almost halved to 3300 kcal/kg. This decline will continue as the share of inferior Indian coal is expected to increase progressively. Consequently, coal consumption per unit power generation and hence ash amount and emissions are observed to be continuously rising.
