摘要

分析了沙角A电厂200 MW机组电除尘器效率低的原因。通过更换阴极线、改进振打系统、出口增设槽形收尘板等措施

使电除尘器除尘效率和可靠性大幅度提高

烟尘排放浓度基本小于100 mg/m3

符合排放标准。

Abstract

The causes leading to efficiency decrease of the electrostatic preciptitator(EP) for 200 MW unit in Shajao A Power Plant have been analysed.Through measures taken

such as replacing cathodic wires

improving the rapping system

and installing slot type dust-collecting plate at the outlet etc.

the efficiency and reliability of EP have been substantially enhanced

the concentration of smoke emission is basically smaller than 100 mg/m3

tallying well with the emission standard.
