Power Technology and Engineering Aims and scope

Abstract

A method for diagnosing mechanical damage and wear of the blade system and the shroud, diaphragm, and end seals is presented. The method is based on the use of the readings of devices for scheduled control of the steam temperature and pressure at the outlet from the cylinders, in the extracted steam, and in the first shoulders of the end seals. Results of practical application of the method at electric power plants including those equipped with data-processing equipment are presented. The introduction of the suggested monitoring will make it possible to pass from scheduled repair to determining the repair time proceeding from the actual condition of the turbine.
