ABSTRACT: A coaxial nontherma紅的l plasma (NTP) reactor器低 was used for the removal 資外of nitric oxide in mis視樹t. The effects of discharge g吧兒ap, thorn number, tooth 現都slice number as well as discharg請些e polarity on NO oxidation and NOx北科 removal were investigated. De計知creasing the discharge gap is f喝市avorable for the NO oxidation and劇跳 NOx removal. The mist is almost captu也醫red completely even under 機快a relative low input energy. Incre輛看asing the thorn numbe道通r of discharge slice or tooth日內 slice number facilitates the energy國短 input in the plasma reactor and thus廠錢 enhances the NO oxidation and 海好NOx removal under a fixed藍好 applied voltage. The energy efficie公通ncy for the positive DC (4.5g NO/kWh) 器湖is three times as mu林短ch as that for the negative DC (1.5 g NO/kWh), corresponding to NO妹我 oxidation efficiency of around 80%.
