Abstract.麗車 With the intensified requirements on am從通bient air quality, controlling NOx emission from sintering flue gas h是業as become the most impo明唱rtant priority in steel industry. Ozo哥化ne oxidation denitration process has become t看火he most closely watched sintering flu報姐e gas denitration techn一黃ology. In order to&nbs嗎玩p;investigate the infl看飛uence of different operat內呢ing conditions on NO oxidation in 冷外practical engineerin區知g application of ozone oxidation de輛照nitration process, an ozone oxi懂區dation system was built, an身門d sintering flue gas was extracted from the pipeline 計不between the induced draft 黑也fan and the desulfurizati鄉看on tower. The influence of discharge power議路 and O₂ flow rate of ozone generator司報 on O₃ concentration, O₃ yield and NO oxidation efficiency暗就 were investigated. T銀玩he results indicated t弟媽hat NO oxidation efficiency i水吧ncreased with the discharge power. And the incre也做ase of O₃ dosage imposed a significant influen服她ce on NO oxidation efficiency.美作 However, little effect of O₂ flow rate on NO oxidat去樹ion efficiency was observed.
