Typical calorific values of fuels

Net calorific value (CV) or Lower Heating Value (LHV) given for all fuels. This means that the latent heat of vaporization of the water vapour created by combustion is not recovered by condensation

Fuel  Net CV by mass  Bulk density Energy density by volume
GJ/tonne kWh/kg   kg/m3  MJ/m3 kWh/m3
Wood chips (30% MC)  12.5  3.5 250   3,100 870 
Log wood (stacked - air dry: 20% MC)  14.7  4.1  350-500  5,200-7,400  1,400-2,000
Wood (solid - oven dry)  19  5.3  400-600  7,600-11,400  2,100-3,200
Wood pellets (10% MC)   17  4.8  650  11,000  3,100
Miscanthus (bale - 25% MC)  13  3.6  140-180  1,800-2,300  500-650
House coal  27-31  7.5-8.6  850  23,000-26,000  6,400-7,300
Anthracite 33 9.2 1,100 36,300 10,100
Heating oil 42.5 11.8 845 36,000 10,000
Natural gas (NTP)  38.1  10.6  0.9  35.2  9.8
LPG  46.3 12.9   510 23,600   6,600
