Application of Five Stages Electrostatic Precipitation Technology in Renovation of Dust-Collector for Power Station Boiler

摘要

Through analyzing the dust characteristics and operating status, combining with electrode matching experiments and simulation condition test, this paper has carried out performance renovation on a three-fields wire-plate type electrostatic precipitator(ESP) for 4＃boiler of 6MW generator set by using Five Stages Electrostatic Precipitation Technology(FSEP), which has deduced dust emission from 130mg/Nm3 to 47.5mg/Nm3 and maintained stable operation without changing the electric fields and cross-sectional area of original equipment. That has demonstrated its good application prospect.
