ABSTRACT: A coaxial nonthermal plasm老是a (NTP) reactor was used for the 弟山removal of nitric oxid看做e in mist. The effects of d紅了ischarge gap, thorn number, tooth s門黃lice number as well as d腦笑ischarge polarity on NO oxidation a少鐵nd NOx removal were investigated快錢. Decreasing the discharge購影 gap is favorable for the NO ox吃得idation and NOx removal. The mis朋資t is almost captured com鄉問pletely even under a relative low inpu一冷t energy. Increasing the thorn number 輛討of discharge slice or to花妹oth slice number facilitates the 理門energy input in the 白區plasma reactor and thu廠用s enhances the NO oxidati笑爸on and NOx removal under a fixed appli少雨ed voltage. The energy ef媽機ficiency for the posit個土ive DC (4.5g NO/kWh) is three t林司imes as much as that for the她書 negative DC (1.5 g NO/kWh), corresponding to N房吧O oxidation efficiency of a得大round 80%.
