摘要

近年来，人们研究了各种气体放电和电子束法去除烟气中的NO/ subx /和SO/ sub2 /的方法。重复脉冲发电机的最新发展使脉冲流光电晕放电在去除NO/sub x/和SO/sub 2/方面有了成功的机会。在火力发电厂进行了利用实际烟气去除NO/sub x/和SO/sub 2/的实验。结果表明，在流速为0.8 l/min、重复次数为7脉冲/秒(pps)的条件下，NO去除率约为90%，SO/sub 2/去除率约为50%。NO去除率与气体流速成反比。当NO去除率为50%时，NO去除率为900 /spl mu/mol/Wh。

NO/sub x/ and SO/sub 2/ removal by pulsed power at a thermal power plant

Recently various methods involving gas discharges and electron beams have been studied for the removal of NO/sub x/ and SO/sub 2/ from flue gases. The recent development of repetitive pulsed power generators gives the pulsed streamer corona discharges a chance of success in the removal of NO/sub x/ and SO/sub 2/. Experiments for the removal of NO/sub x/ and SO/sub 2/ using actual flue gases were performed at a thermal power plant. The results showed that about 90% of NO and about 50% of SO/sub 2/ were removed at a flow rate of 0.8 l/min and a repetition rate of 7 pulses per second (pps). The removal ratio of NO varied inversely proportional to the gas flow rate. The energy efficiency of NO removal was 900 /spl mu/mol/Wh when 50% of NO was removed.
