Influencing Factors for NOx Reduction by SCR

摘要：

　　At all-state test of SCR system,the maximum NOx emission value occurs at 1100r/min and 50% of The throttle opening degree condition.The NOx emission value is 2611.08ppm.During simulation research,Influencing factors such as urea spray,reaction temperature,space velocity and NH3/NOx concentration proportion are elaborated.During 0.4s simulation cycle,it shows better atomize results and better homogeneity.The reaction temperature on catalyst is kept at 319℃ value which is helpful for continuous SCR reaction.NH3/NO concentration proportion is kept from 0.2 to 0.3,which NOx reduction rate is from 65% to 75% in accordance with test results on the base of 1200r/min condition.The research can provide references for optimization on compact SCR system.
