Abstract. Ozone oxidation denitration process去區 has become the most closely watched s黑見intering flue gas denitration technology currentl關有y. In order to investigate the in關開fluence of different 林業operating conditions on NO oxidation in practical 哥問engineering application of t銀姐his technology, an ozone 森冷oxidation system was built,知開 and sintering flue gas was extracted校體 from the pipeline between the in金哥duced draft fan and the desul下車furization tower. The influence of fl吃南ue gas flow and inle子慢t NO concentration on NO oxidation wa又男s investigated by orthogonal experiments. Th吃兒e results indicated that N那間O oxidation efficiency increased wi一們th the O₃ yield of ozone generator and O₃ dosage under any flue gas內內 conditions. Under the same inlet NO c錢國oncentration, NO oxidation efficiency decreased with少資 the increase of flue gas flow. Under 內舊the same flue gas flow and O₃ dosage, with the increase of inlet NO湖為 concentration, the O₃ utilization rate increased while the刀生 average oxidation energy consump報資tion of each NO molecule de黃高creased, which was beneficial風吧 to promote the NO oxidation efficiency. In practical 媽照engineering application, the setting o間很f O₃ dosage should take into account服請 both engineering des要電ign indicators and economy. Ozone請知 oxidation denitration process could ac友飛hieve NO oxidation efficiency h民湖igher than 90% through reason河鐵able design, indicati樂理ng a good industrial a南購pplication prospect in the treatment of sinte風個ring flue gas.
