Biomass calorific value calculator
Use the following calculator to help you determine the energy content, or calorific value, of your woody biomass fuel. For more details about the effects of moisture content on the calorific value of biomass, see below. A more advanced calculator allows for the specification of the moisture / water content.
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 factor in the variability in combustion behaviour of woody biomass. The following figure shows the dependence of net calorific value on moisture content (dry basis) and water content (wet basis).
The theory behind this calculator is described here.
