Abstract

Abstract: Based on the statistical data of power consumption and specific power consumption for 197 sets of electrostatic precipitators in coal-fired power plants in China, the evaluation, testing, and calculation method of energy efficiency for electrostatic precipitator (ESP) are put forward. The ESP efficiency evaluation for the ultra-low emission project is conducted by using the proposed method. It is shown that the low-low temperature ESP has better efficiency, but with a higher operating energy consumption. The wet electrostatic precipitator (WESP) achieves steady dust ultra-low emissions, but with a higher operating cost. When the unit is in low load operation, the electric energy consumption is high. There is still room for further saving on the energy consumption of electrostatic precipitators and the research on the energy efficiency optimization technology of the electrostatic precipitator is suggested.

Key words: coal-fired power plant, electrostatic precipitator, power consumption, specific power consumption, ultra-low emission
