In order to develop methods of plasma injection for removing pollutants such as NO_x and SO_x contained in combustion exhaust gas, the authors have investigated radical formation in Ar and N_2 arc plasma. It has already been concluded that the NO_x removal efficiency has a maximum value in the low range of plasma power. In this paper for the purpose of further savings of the electrical energy in practical use, N_2 gas is excited by passing through a corona discharge tube in a high-voltage field, and produced nitrogen radicals are mixed with simulated exhaust gas (N_2+O_2+CO_2+H_2O+NO) to reduce the NO_x contained in gas. The O_2 and H_2O contents have no effect on the NO_x reduction, and CO gas from CO_2 is not generated. The NO_x reduction ratio of about 10% is obtained by N_2 corona discharge under the input power of 30 watts.
