摘要
唐山发电厂5号汽轮机系捷克列宁格勒金属工厂1956年生产的25MW机组,到1992年底已运行35年,超过了设计运行年限。为了保证机组的安全运行,本文介绍了对该机的汽轮机转子寿命的分析评估工作,在对汽轮机转子运行受力分析的基础上,绘制了转子寿命损耗曲线,同时结合机组已耗转子寿命的估计,对该机组的剩余寿命提供了较为可靠的依据。本文亦可供同类型汽轮机转子寿命分析时参考。
The NO. 5 turbine unit of Tangshan Power Plant, wnich is a 25MW unit manufactured jn 1956 in Czechoslovakia,has operated for 25 years and exceeded its design operation lile in 1992 [ntroduced in this paper is the analysis and evalu-ation of the turbine rotor life and rotor life consumption curve based on operational stress. And with calculation to thecomsumed rotor life. reliable data are provided to the residual life prediction of the turbine unit, which can also be used bythe other units of the same design.
