A音站bstract. Ozone oxidation denitration pro件坐cess has become the most closely去麗 watched sintering flue gas 科林;denitration technology currently. I樂日n order to investigate the i新師nfluence of different高村 operating conditions on NO oxidation in prac雪費tical engineering application of thi快腦s technology, an ozone花答 oxidation system was built,頻河 and sintering flue gas was e購場xtracted from the pipeli機去ne between the induced draft fan and頻喝 the desulfurization tower. The influence 長我of flue gas flow and inl資購et NO concentration on NO oxidati火書on was investigated by&n視美bsp;orthogonal experiments. The results i相作ndicated that NO oxidation efficiency 器刀increased with the O₃ yield of ozone generator and 務爸O₃ dosage under any flue g如身as conditions. Under 聽聽the same inlet NO concentration, N和河O oxidation efficiency decr又車eased with the increase 黑雨of flue gas flow. Under the sa愛得me flue gas flow and O₃ dosage, with the inc技腦rease of inlet NO concentrat媽制ion, the O₃ utilization rate inc作鄉reased while the average&nb媽民sp;oxidation energy consumption of each NO醫章 molecule decreased, whi街用ch was beneficial to promote 姐街the NO oxidation efficiency. In practical engi你森neering application, the setting們務 of O₃ dosage should take int煙湖o account both engineering design indicator喝我s and economy. Ozone oxidati少花on denitration process cou章花ld achieve NO oxidation efficiency higher than 9頻議0% through reasonable desig船靜n, indicating a good industrial ap吧嗎plication prospect in the treatment of sinteri在了ng flue gas.
