Abstra外雜ct. With the intensified requiremen大錢ts on ambient air qualit票什y, controlling NOx emission from sintering flue gas has become t行說he most important priorit睡體y in steel industry. Ozone oxidatio員船n denitration process has become the most closely wa拿吧tched sintering flue ga算習s denitration technology. In orde電木r to investigate the influence of d得月ifferent operating conditions on NO唱計 oxidation in practical engineering&nbs土校p;application of ozone oxidation 了哥denitration process, an內影 ozone oxidation system was bui林白lt, and sintering flue gas was extracted fr器請om the pipeline between t學房he induced draft fan and the des和影ulfurization tower. 關明The influence of discharge 舊件power and O₂ flow rate of ozone generat舊數or on O₃ concentration, O₃ yield and NO oxidation efficiency were investig多火ated. The results indic間銀ated that NO oxidation efficiency inc會了reased with the 年風discharge power. And the increas音站e of O₃ dosage imposed a signif你照icant influence on NO oxid舊們ation efficiency. However, little effe資我ct of O₂ flow rate on NO oxidation effi嗎黑ciency was observed.
