摘　　要：分析了(电除尘器)EP净化烟气所需的理论功率消耗以及EP运行时的实际功率消耗,两者相差较大。实际上,EP运行时的高压电能消耗应分为"有效"、"反效"、"无效"与"固有能耗"4部分,有效电能很小,而另外3种能耗所占比例较大。通过技术措施,可以提高有效电能比例,降低另外3种能耗比例。根据怀特有关EP供电理论和EP运行现状以及提效节能型EP高压供电设备的研发成功与推广,我国燃煤电厂EP的供电应由目前的高电流"大功率高能耗"的单一火花整定工作方式转移到高电压低电流的提效节能工作方式的科学轨道上来。It was analyzed that theoretical and practical watt consumption needed in flue gas cleaning in electrostatic precipitator in this paper to find that they were quite different from each other. Actually, the operating electrical energy consumption of EP should be classified as effective, minus effective, ineffective and natural energy consumption. The effective electrical energy is very little, but the proportion of the others is big. The proportion of effective electrical energy can be enhanced and the others can be reduced via techno-measure. Based on the White＇ s theory about EP power supply, the operating status quo of EP and the successful study and extension of high voltage power supply facility of EP with efficiency enhancing and energy saving, the working manner of electrostatic precipitator power supply should be transferred from the single spark setting of high current, high power and high consumption to the scientific track of high efficiency and energy .saving in coal-fired power plants in China.
