The effects of gas compositions and reaction conditions on NO conversion by positive streamer discharge were experimentally investigated by using a link tooth wheel-cylinder reactor.The results showed that NO conversion increased with increasing O_(2) concentration and NH3 concen-tration,but decreased with increasing inlet NO concentration and gas flow rate.The addition of CO_(2) or H_(2)O to the feed gas promoted NO conversion by increasing the maximum discharge voltage,and NH4NO3 was formed in the presence of NH_(3).There was a most suitable range interval between discharge tooth wheels if both NO conversion and energy consumption were considered.Increasing applied voltage resulted in the increase in the amount of O_(3) generated by streamer discharge.
