ABSTRACT: A coaxial 視技nonthermal plasma (NTP) reactor w快音as used for the remova能來l of nitric oxide in m媽風ist. The effects of dis低匠charge gap, thorn numbe內房r, tooth slice number a木喝s well as discharge pola會線rity on NO oxidation and NOx removal w船件ere investigated. Decreasing the di離林scharge gap is favorable for做歌 the NO oxidation and NOx r舊紅emoval. The mist is almost ca子音ptured completely eve森劇n under a relative low input e報現nergy. Increasing the t美現horn number of discharge s員數lice or tooth slice numbe了電r facilitates the energy inp服街ut in the plasma reactor and 國家thus enhances the NO oxidatio時到n and NOx removal un機嗎der a fixed applied 費務voltage. The energy efficiency for the匠女 positive DC (4.5g NO/kWh) is thr長又ee times as much as th計花at for the negative DC (1.5 g NO/kWh), corresponding t如朋o NO oxidation efficiency of腦下 around 80%.
