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 = MJ/t = J/kg = kcal/kg = kWh/kg.

Enthalpy loss – the loss in boiler efficiency due to converting the inherent moisture in fuel to vapor is not captured when the NCV is used calculate the boiler efficiency. Referencing the boiler efficiency to GCV gives a more accurate picture of the efficiency as it takes into account all the energy contained in fuel and draws our attention to the enthalpy loss.
