ABSTRACT: A coaxial nonthermal plasm關下a (NTP) reactor was used for the rem紅都oval of nitric oxide in mist. T開笑he effects of discharge gap, thorn動城 number, tooth slice number as 了長well as discharge polarity on NO oxi行中dation and NOx remov她媽al were investigated. Decreasing 有商the discharge gap is favo時唱rable for the NO oxidation訊員 and NOx removal. Th個讀e mist is almost captured completely影國 even under a relative low in呢區put energy. Increasing 舊吃the thorn number of 上刀discharge slice or tooth slice numbe遠志r facilitates the energy in員服put in the plasma re在林actor and thus enhance學匠s the NO oxidation and NOx removal u麗時nder a fixed applied voltage. The ener物你gy efficiency for the計章 positive DC (4.5g NO海你/kWh) is three times as mu術會ch as that for the negative DC (1.5 g NO/kWh), corresponding to N見空O oxidation efficiency of around花那 80%.
