Abstract: Taking the ozone injector with a specific structure as study object,the factors that affect the ozone oxidation process are analyzed deeply by means of numerical simulation method combining with standard k-ε model,species transport model and laminar finite-rate model.Analysis result shows that the oxidation efficiency of NO raises with the increasing molar ratio of O3/NO in flue gas,but the growth rate decreases gradually.The oxidation efficiency of NO will decrease with the increasing temperature when the temperature of flue gas locates in the range of 100-250℃ and the molar ratio of O3/NO is set as 1.Meanwhile,the existence of SO2 in flue gas has no obvious impact on oxidation efficiency of NO.
