Abstract. Ozone oxidation denitration鐘朋 process has become the most c她跳losely watched sintering flue gas&著輛nbsp;denitration technology currently. In 新山order to investigate the influen門上ce of different operating conditio河綠ns on NO oxidation in practi些請cal engineering application of兵都 this technology, an ozone oxidation sy音好stem was built, and sintering flue gas was extracted f醫美rom the pipeline between the induced d關城raft fan and the desulfurizati媽工on tower. The influence of fl南內ue gas flow and inlet NO co中會ncentration on NO oxidation was 時放investigated by 場對;orthogonal experiments. The results in看些dicated that NO oxidation effici吃路ency increased with the O₃ yield of ozone generator and O₃ dosage under any flue gas 紅姐conditions. Under the same in讀了let NO concentration, NO oxidation efficiency de草些creased with the increase 劇花of flue gas flow. Und內玩er the same flue gas flo就她w and O₃ dosage, with the incre師來ase of inlet NO concentrat冷樹ion, the O₃ utilization rate increased這還 while the average 知鐘;oxidation energy con雪門sumption of each NO mole學國cule decreased, which was beneficial 冷樂to promote the NO oxidation efficiency. In prac慢農tical engineering applica我件tion, the setting of O₃ dosage should take into 線市account both engineering design微我 indicators and economy. 校就Ozone oxidation denitr了拍ation process could achieve NO&nb志雪sp;oxidation efficiency友章 higher than 90% through reaso去務nable design, indicating a good ind自他ustrial application&nb服音sp;prospect in the treat商能ment of sintering flue gas.
