Biomass calorific value calculator - Gen Less tools
Simple calculator. Oven-dry woody biomass typically has a calorific value of 18-21 MJ per kg on a dry basis (this is the gross calorific value). Most fuels are not oven dry when burnt and the water in the wood must be evaporated, detracting from the extractable energy* (or net calorific value). Moisture or water content is the single biggest ...
