Ab票紅stract. Ozone oxidation denitrati放話on process has become the most closely 兵藍watched sintering fl事知ue gas denitration technology currently. In or冷工der to investigate the influence of 如有different operating conditions on 的哥NO oxidation in prac遠市tical engineering application of this 廠是technology, an ozone oxidation sy計綠stem was built, and sintering flue gas was間為 extracted from the pipeline between 視書the induced draft fan and t西微he desulfurization&n身北bsp;tower. The influence of flue g兒就as flow and inlet NO concentrati紙市on on NO oxidation was investigated 遠有by orthogonal experiments. The resul化都ts indicated that NO oxidation efficie得海ncy increased with the O₃ yield of ozone generator and O₃ dosage under any flue gas conditio歌黃ns. Under the same inlet NO concen錢南tration, NO oxidation efficiency decreased with t機店he increase of flue gas flow制呢. Under the same flue gas flow and O有睡₃ dosage, with the increase of inl睡紅et NO concentration, the O₃ utilization rate increased 空雪while the average oxidation energy consumption拿呢 of each NO molecule decreased, 很你which was beneficial to promo唱都te the NO oxidation efficiency. In practical eng答科ineering application, the setting of 分線O₃ dosage should take into 間師account both engineering design indicators 錢但and economy. Ozone oxidation deni樂公tration process could年商 achieve NO oxidation efficiency higher th窗章an 90% through reasonable desi森著gn, indicating a good 唱麗industrial application prospect in the treatment of sintering 章商flue gas.
