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.

GCV (Gross Calorific Value) and NCV (Net Calorific Value) are both measures of the amount of energy released when a fuel is burned. The main difference between the two is that GCV includes the latent heat of vaporization of water in the combustion products, while NCV does not. This means that NCV provides a more accurate representation of the ...
