在模拟电厂烟气的情况下，利用短时间的100纳秒脉冲功率去除氮、氧、水蒸气和一氧化氮混合物中的一氧化氮（NO）。报道了气流量、反应器长度和脉冲重复率对NO去除率及其能量效率的影响。在固定气体流量下，由于进入放电的能量增加，随着脉冲重复率的增加，NO去除率增加。在一定脉冲速率下，随着气体流量的减小，NO的去除率增加，这是由于气体在放电反应器中停留时间的增加，从而促进了O和N自由基的增加，从而降低了NO。NO的能量去除率（mol/kWh）随气体流量的增加和NO去除率的增加而降低。在不同反应器长度下，输入流量的能量密度（J/I）越大，NO去除率越高。
A short duration of 100-ns pulsed power has been used to remove nitric oxide (NO) in a mixture of nitrogen, oxygen, water vapor, and NO, simulating flue gases from a power station. The effects of the gas flow rate, the reactor length, and the pulse repetition rate on the percentage of NO removal and its energy efficiency are reported. The percentage of NO removal at a fixed gas flow rate increased with increasing pulse repetition rate due to the increased energy into the discharge. At a fixed pulse rate, the removal of NO increased with decreasing gas flow rate due to the increased residence time of the gas in the discharge reactor, thus facilitating the creation of increased radicals of O and N which then decreased NO. The energy removal efficiency of NO (in mol/kWh) decreased with increasing gas flow rate and increasing removal ratio of NO. The removal of NO increased with increasing energy density (J/I), input into the discharge at different reactor length.
