Abstract. With the intensified 她低requirements on ambient 時線air quality, controlling愛還 NOx emission from sintering flue gas has bec店劇ome the most important視讀 priority in steel indust開兒ry. Ozone oxidation 雪友denitration process has become the most clo你個sely watched sinteri很空ng flue gas denitration都車 technology. In order to 她玩;investigate the influence 照線of different operatin上服g conditions on NO oxidation in pr討中actical engineering application of ozone oxidation denit機東ration process, an ozone oxidation s鐘是ystem was built, and sin近長tering flue gas was extracted from子唱 the pipeline between生場 the induced draft fan and 舊快the desulfurization tower. The&nbs體廠p;influence of discharge power and O₂ flow rate of ozone generator on 土器O₃ concentration, O₃ yield and NO oxidation efficiency were村家 investigated. The results indi開大cated that NO oxidation eff動相iciency increased with t件煙he discharge power. And the increase o亮快f O₃ dosage imposed a significan我票t influence on NO oxidation ef場媽ficiency. However, little effect of O₂ flow rate on NO oxidat家要ion efficiency was observed.媽請
