Abstract
In this paper, the effects of CO2 injection rate on the flow stabilized pos itive DC corona discharge in dry air are experimentally investigated. As an example of chemical reactions induced by different corona modes, NO remova l is also studied in gaseous mixtures of N-2+O-2+CO2+NOx at atmospheric pre ssure and in room temperature. The transition between glow and streamer can be controlled by CO2 on and off injection. 95% of NO can be removed under streamer corona discharge with an energy yield of about 12.5-25g(NO)/kWh. H owever, for glow corona discharge, the NO removal is negligible.
