Abstract. With the intensified requirements on 要區ambient air quality,空海 controlling NOx emission from sintering flue gas has become the most 間鄉important priority in steel ind冷數ustry. Ozone oxidation denitration 黃腦;process has become the most closely 暗身watched sintering flue gas denitr刀輛ation technology. In order to&n讀開bsp;investigate the influence of d去黃ifferent operating conditions on NO o照外xidation in practical engineering&nb兒相sp;application of ozone oxidation denitrat知師ion process, an ozon開老e oxidation system was bu到說ilt, and sintering flue&nb物男sp;gas was extracted from 草來the pipeline between the induc能妹ed draft fan and the desulfur子大ization tower. The influence of discharge po外路wer and O₂ flow rate of ozone generator 他那on O₃ concentration, O₃ yield and NO oxidation efficiency were invest數著igated. The results indica外會ted that NO oxidation efficien討腦cy increased with th文們e discharge power. And the incr關師ease of O₃ dosage imposed a significant i遠花nfluence on NO oxidat工站ion efficiency. However, little effect of O₂ flow rate on NO oxid多員ation efficiency was observed.
