低温省煤器漏水分析与处理

Water Leakage Problems of Low Temperature Economizer and Remedial Measures

广州员村热电有限公司锅炉近期发生多起低温省煤器漏水事故。为减少因低温省煤器漏水而影响锅炉运行,通过对泄漏点的情况检查、分析,发现由于低温省煤器支撑梁处漏风而引起的。分析了漏风对低温省煤器的影响,介绍了支撑梁密封处理的结构。

Recently, Guangzhou Yuancun Cogeneration Power Plant's boilers incurred quite a number of failures, caused by water leakage of low temperature economizers. To reduce the impairing effect on boiler operation caused by water leakage of the low temperature economizers, following an inspection and analysis of the leakage locations, it was ascertained that the failure was caused by air escaping at places where the economizer was propped by supporting beams. The effect of air leakage on the low temperature economizer is simultaneously being analyzed together with a description of structural sealing measures adopted at the supports.
