Study on energy saving and emission reduction of high voltage power supply control of ESP

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.
