Biomass can be burned in a conventional boiler that has been adapted for the type of biomass to be used. Generally biomass boilers are somewhat larger because of the lower calorific value of the fuel. It is essential to ensure complete combustion to minimise environmental emissions and residues. Some types of boiler will have automatic feeding of the biomass such as wood pellets, but other types will require supplying fuel at various intervals. The residues are generally beneficial for the soil.
