摘要

粤泷发电有限责任公司自2004年2月投产到2006年6月期间汽轮机冷油器铜管发生了多次泄漏。为此

从铜管材质、冷却水水质、汽轮机油油质、停(备)用方式等方面进行了一系列的分析

找出了铜管腐蚀、泄漏的主要原因:(1)冷油器管材不适宜冷却水水质

(2)停(备)用方式不当。为此

将冷油器管材BFe10-1-1更换为不锈钢管

并改变停(备)用方式

使问题得以解决。

Abstract

Frequent copper tube leakage had occurred in oil-cooler of steam turbines during operation period from Feburary

2004 to June

2006 at Yuelong Power Generation Co Ltd.For this

a series of analysis has been carried out from aspects

such as material quality of copper tubes

water quality of cooling water

oil quality of turbine oil

and shutdown(standby) mode etc.

finding out the main causes resulting in corrsion and leakage of the copper tubes to be as follows:(1) the quality of copper tube materials isn't suitable for the quality of cooling water;(2)the shutdown(standby) mode is improper.Thereby

the copper tubes BFe10-1-1 of oil-cooler have been replaced by using stainless steel tubes

and the shutdown(standby) mode being improved

making the said problem finally to be solved.
