Laboratory testing of Domestic Hot Water Boiler while fired with different Biomass Pellets

This work presents combustion and emissions results obtained from burning several biomass pellets (wood and straw from different agricultural residues). Fuel analysis, net calorific value, gaseous emissions (CO, NOx), ash agglomeration and residue analysis is provided for comparison. Tests were performed at laboratory conditions according to the relevant CEN standard in conventional type of high efficient/low emission domestic wood burning boiler, equipped with 6-26 kW rotary combustion chamber burner, particularly suitable for burning fuels with high content of non-combustible impurities. The results show that, although available on the market, not all agricultural residues are applicable for combustion in the form of pellets, among others, due to low combustion efficiency, gaseous emissions and lumped residue particles containing large amounts of unburned carbon.
