Workshop proceedings: life assessment and repair of steam turbine casings
- ed.
Two fundamental changes have become apparent in recent years for the future operation of steam turbines. The first is that units presently 20 to 30 years of age will be operated far beyond their ''design'' life. Secondly, older units are more likely to be used for cyclic duty. These two factors contribute to increased potential for turbine casing problems. These problems include thermal fatigue cracking, horizontal joint distortion and water erosion in the LP sections. A number of design, material and operational changes have been implemented in recent years to alleviate the problems of cracking and distortion. In addition, a number of repair and refurbishment procedures have also been implemented with varying degrees of success. In order to consolidate all the available industry experience on the subject, a workshop was organized by EPRI in Palo Alto on June 4, 1985. The workshop was attended by turbine manufacturers, consulting engineers and utilities. Proceedings of this workshop are contained in this report. Ten papers have been entered into EDB and ERA; the final discussion was not entered. (LTN)
