Abstra喝慢ct. With the intensified requi木年rements on ambient air qual黑月ity, controlling NOx emission from sintering flue gas has become the mo國頻st important priority in steel 視數industry. Ozone oxidation de街關nitration process has become the most c子拿losely watched sintering f事劇lue gas denitration techno村報logy. In order to&nbs山音p;investigate the influen紙體ce of different operating condition綠票s on NO oxidation in practical engineer自南ing application of ozone oxidation denitr匠頻ation process, an ozone o作就xidation system was built, and sinter為爸ing flue gas was extracted from the pipeline bet照就ween the induced draft fan and the d新友esulfurization tower. The influence of discharge powe學但r and O₂ flow rate of ozone generator on O₃ concentration, O₃ yield and NO oxidation efficiency were inve得線stigated. The results indicated tha和白t NO oxidation efficie開匠ncy increased with the discharge power. And the i水聽ncrease of O₃ dosage imposed a significant嗎術 influence on NO oxida熱年tion efficiency. However, little effect of O₂ flow rate on NO oxidation effic讀了iency was observed.
