Abstract: After the ultra-low emission transformation, it is of great significance to optimize the electricity consumption of dust collection system in coal-fired power plants with the dust emission control still maintained at the certain level simultaneously. Performance testing is an indispensable part of this energy-saving optimization. In this paper, experimental researches on the energy-saving optimization of the dust collection system under 10 operation conditions with different combinations of charging ratio, spark rate, average secondary current and average secondary voltage have been done in a 330 MW coal-fired power plant. It is discovered from the testing results regarding several basic principles of dust collection system optimization that raising parameters of the first field will lead to significantly higher dust collection efficiency, while increasing the parameter values of the last field properly will significantly lower down the final emission concentration.

Key words: coal-fired power plant, electro-static precipitator (ESP), performance testing, energy-saving, operation optimization
