英文摘要	Based on the demand of sintering/pelleting flue gas ultra-low emission, a semi-dry method using a spray dryer absorber(SDA) combined with O_3 oxidation was proposed for simultaneous removal of SO_2 and NO.Effects of O_3 injection site, O_3 /NO molar ratio, and spray tower temperature on the removal efficiencies were investigated.It was revealed that both desulfurization and denitrification efficiencies could reach to 85% under the conditions of setting O_3 injection site inside of tower, O_3 /NO molar ratio 1.8, spray tower temperature 85 °C, Ca/(S + 2 N) molar ratio 2.5 and slurry flow rate 300 mL/hr.CaSO_3 /Ca(OH)_2 mixture slurry was used as absorbent to simulate operating conditions in iron and steel industry.The result shows that the addition of CaSO_3 weakens both removal efficiencies.In addition, the reaction mechanism of simultaneous removal of SO_2 and NO using SDA combined with O_3 oxidation was proposed.
