ABSTRACT: A coaxial nonthermal plasm紅也a (NTP) reactor was use車身d for the removal of nitri玩道c oxide in mist. The effects of disc站線harge gap, thorn number, tooth sli鄉麗ce number as well as discharge p動服olarity on NO oxidation an東木d NOx removal were investigated. Decre朋開asing the discharge gap is 雜師favorable for the NO oxi不麗dation and NOx removal. The mist 做來is almost captured completely even 一討under a relative low input energy件哥. Increasing the thorn number of di森紙scharge slice or tooth slice number fac討問ilitates the energy input in the p多見lasma reactor and thus enh白睡ances the NO oxidation and 街筆NOx removal under a fixed appli錯通ed voltage. The energy efficie服東ncy for the positive有她 DC (4.5g NO/kWh) is three訊站 times as much as that for the n不章egative DC (1.5 g NO/kWh), corresponding to NO些坐 oxidation efficiency of around年女 80%.
