The present study aims to investigate flue gas emissions, particularly pollutants CO, NOx and particle
emissions, of a domestic biomass boiler under various operating conditions. The experimental methodologies
are systematically introduced. If the primary and secondary air supply for the biomass furnace
are provided by the factory-set openings and vent tubes, the flue gas emissions measured are NOx
54.92 ppmv, CO2 11.98 vol%, CO 0.24 vol%, O2 8.19 vol% and PM0.1e10 concentrations 72.7 mg/Nm3 by
burning wood pellets. In addition, the three kinds of cleaning technologies reducing particle emissions
are also introduced.
