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

为了发展等离子体喷射法去除燃烧废气中的NOx和SOx等污染物，作者研究了Ar和N_2电弧等离子体中自由基的形成。实验结果表明，在等离子体功率较低的范围内，NOx的去除效率有一个最大值。为了在实际应用中进一步节约电能，本文采用高压电晕放电管激发N_2气体，使其产生的氮自由基与模拟废气（N_2 + O_2 + CO_2 + H_2O + NO）混合，以回收废气中的NOx。O_2和H_2O的含量对NOx的还原率没有影响，CO_2没有生成CO气体。在输入功率为30W时，N_2电晕放电对NOx的还原率可达10%左右。
