ABSTRACT: A coaxial nonthermal p明城lasma (NTP) reactor was used動身 for the removal of nitric oxide i內看n mist. The effects of discharge g電這ap, thorn number, tooth slice numbe鄉他r as well as discharge polarity on NO o站短xidation and NOx removal were i是劇nvestigated. Decreasing the d員白ischarge gap is favorable 樹亮for the NO oxidation and NOx remov照問al. The mist is almost captured c紙近ompletely even under 我黑a relative low input energy. Increasin能會g the thorn number of discharge 草算slice or tooth slice number facili是身tates the energy input到外 in the plasma reactor and thus enhan木鄉ces the NO oxidation and 術電NOx removal under a f也人ixed applied voltage. The energy effici影們ency for the positive DC (4.5g NO/kW報人h) is three times as much a這放s that for the negative DC (1.5 g NO/kWh), corresponding 不裡to NO oxidation effic快業iency of around 80%.
