ABSTRACT |
The effects of pulse corona discharge on the removal of SO2 and NOx from simulated Hue gas have been studied. Initial NO and SO2 concentrations and the amount of ammonia added were changed to know the effects on N2 removal. An efficiency 96% of the SO2 removal and 70% of the NO removal in pulse corona reactor have been achieved with the ammonia addition, for the SO2 and NO initial concentrations being 480 ppm and 230 ppm, respectively. A numerical model for SO2 and NO conversion in homogeneous gas flow has been developed. The spatial non-uniformity of gas parameters associated with existence of many streamer channels in discharge chamber is taken into account. The comparison between experiments and modeling shows that the SO2 removal is mainly dominated by OH and a negative ion O3 and the NO conversion results from the reactions with O3 OH and N. |
