摘要

分析了影响电除尘器运行的因素

找出了华能汕头电厂1号、2号机组锅炉电除尘器除尘效率降低的主要原因

如反电晕、电晕线粗大和阳极板粉尘堆积、电晕闭塞、锅炉排烟温度高和压力低、高压短路、高压控制柜的控制功能不良及取样电阻阻值飘移等。实施相应的整改措施后

该除尘器除尘效率明显提高。

Abstract

The factors affecting operation of electrostatic precipitator(EP)have been analysed

finding out the main causes resulting in efficiency-reducing of EPs for boilers no.1 and no.2 in Huaneng Shantou Power Plant

such as inversed corona

thick corona wires and dust deposition on anode plates

blocked corona

unsuitable temperature and pressure of exhaust flue gas from boilers

short-circuit in the high-voltage side

and deviation of control function of high-voltage control cabinet

and deviation of the sampling resister etc..After implementation of corresponding measures of retrofit

the dust removal efficiency of EPs has been substantially enhanced.
