ABSTRACT: A coaxial nont分著hermal plasma (NTP) 湖子reactor was used for t金嗎he removal of nitric光音 oxide in mist. The effects of discharg個路e gap, thorn number, tooth slice n從呢umber as well as discharge p學海olarity on NO oxidation 小森and NOx removal were i答行nvestigated. Decreasing the discharge 樹低gap is favorable for the NO o動村xidation and NOx removal.信高 The mist is almost captured 數跳completely even under北器 a relative low inpu時她t energy. Increasing t南公he thorn number of discharge slic樹短e or tooth slice number facilit弟現ates the energy input in th報空e plasma reactor and thus enhance答分s the NO oxidation and NOx removal u學算nder a fixed applied voltage. The慢錯 energy efficiency for t紅快he positive DC (4.5g NO/kWh) is thr文樂ee times as much as tha身校t for the negative DC (1.5 g NO/kWh), corre對員sponding to NO oxidation efficiency of 請森around 80%.
