Abstract
Along with the increasing strictness of environmental protection requirements in relevant national standards, innovative improvement of ESP (ElectroStatic Precipitator) for 2×600 MW unit in Shanxi Lujin Wangqu power plant is urgently needed. First, investigations for three techniques including bag-type precipitator, electrostatic-bag compound precipitator, and three-phase high efficiency power supply are carried out. Then, through a series of procedure including improvement scheme design, construction process determination, and technical requirement clarification, construction work is orderly launched. The results of acceptance check show that, efficiency, resistancy, leak out rate and outlet dust concentration of improved ESP all meet the requirement of certified values, and far reach the relevant emission standards. Moreover, the power saving rate is up to 25%~40%, indicating the favorable achievement of both social benefits and economic benefits.关键词
