摘　　要：等离子电离技术是烟气脱氮的重要发展方向.分析了等离子电离技术烟气脱氮的机理以及电极结构参数对其的影响.实验结果表明,通过增大电介质的介电常数和内电极的半径,能够减小击穿电压,延长放电时间,提高氮氧化物的脱除效率.The flue gas de-NOx by plasma ionization technology is a promising method and the mechanism and influence factors such as dielectric constant and electrode radius, on the plasma ioni- zation technology for flue gas de-NOx are discussed. The results of the experiment show the measures to improve the de-NOx efficiency by increasing the dielectric constant and electrode radius can pro- long the time of discharge by decreasing the breakdown voltage and improve the de-NOx efficiency.
