摘要
研究了采用直流电晕自由基簇射系统脱除烟气中的NOx.实验结果表明,电极喷嘴中的气体组分和流量对电晕放电的电压 电流(V I)特性产生影响,适当调节电极喷嘴中的气体流量可以产生帘状流光电晕.烟气中的水蒸气不仅对电晕放电的V I特性产生影响,而且提高NOx的脱除效率.
Removal of NOx from flue gas with DC corona radical shower system was investigated in the experiment. The results show that both the composition and the flow rate of the gas fed into the nozzles have effect on the V-I characteristic of the corona discharge. The steady curtain shape streamer corona occurs when the flow rate of the fed gas is adjusted. The vapor in the flue gas not only affects the V-I characteristic of the corona discharge, but also enhances the NOx removing efficiency.
