摘要：
The effect of pulse corona discharge on NOx and SO2 concentrations in air has been studied. The initial concentrations and ammonia addition have been shown to influence the removal efficiency. An SO2 removal efficiency of 96% and an NO removal efficiency of 70% in pulse corona have been achieved with ammonia addition, for initial SO2 and NO concentrations of 480 ppm and 230 ppm, respectively. A numerical model for NO and SO2 conversion in homogeneous gas flow has been developed. The spatial nonuniformity of gas parameters associated with the existence of many streamer channels in a discharge chamber is taken into account. A comparison between experiments and modeling shows that SO2 removal is mainly determined by OH and O-3(-). NO conversion is achieved the reactions of O-3, OH and N.
