In a previous study, it was shown by Hilliard and Weinberg and the present authors that pollutants such as nitrogen oxides (NO_x) and soot can be destroyed by nitrogen atoms generated by N_2 plasma. In this study, a small-size, light-weight, simple-structure arc plasma generator is designed for practical applications. It has been examined by the authors that NO_x removal efficiency has a maximum value in the range of low electrical power input to the plasma operated under stable conditions. In order to improve plasma stabilization, argon gas is added to N_2 plasma, and the rate of production of N atoms is estimated by injecting the nitrogen monoxide (NO) gas into a plasma jet. It is concluded that NO removal by use of the (N_2 + Ar) mixing plasma is possible under low voltage (12〜16 V) and power (500〜580 W) conditions.
