In this paper, exhaust gas emissions were compared between conventional gas-phase combustion in both forced exhaust gas concentration of hot-water burner & premixed natural gas/air burner with heater and the catalytic combustion in catalytic honeycomb monolith burner. Test proved that the pollutant emissions of gasphase combustion were higher than that of catalytic combustion. It is shown that the conversion of conventional gas-phase combustion was lower than that of catalytic combustion by measured experimental data. It indicated the advantages of energy-saving and environmental protection for the catalytic combustion.
