摘　　要：利用建造在四川绵阳科学城热电厂的最大烟气处理量为 2 0 0 0 0m3 /h的脉冲电晕等离子体烟气脱硫工业中试装置 ,研究了影响脱硫效率的因素 ,获得了最佳工艺参数。研究结果表明 ,当烟气温度在 6 5～ 70℃ ,烟气水分含量约 10 % ,氨硫化学剂量比为 1∶1,烟气停留时间大于 6s、能耗低于 5Wh/Nm3 等条件下 ,脱硫率达 85 %以上。The paper gives the main parameters for SO 2 removal with gas flow rates of less than 2×10 4 Nm 3/h by using pulsed corona process. This industrial scale facility was constructed at the power plant of China's Science City in Mianyang,Sichuan Prorince. The results show that under such condition as:flue gas flow rate being less than 2×10 4 m 3/h, gas temperature being 65～70℃, water content in the gas being 10%, resident time being 6～10 seconds, stoichiometric ratio of NH 3 to SO 2 being about1∶1, power consumption to operate the pulse conora process being not larger than 5 Wh/Nm 3, the SO 2 removal efficiency is about 85%.
