A METHOD FOR MANAGING LIFESPANS OF HIGH TEMPERATURE GAS TURBINE COMPONENTS AND ITS IMPLEMENTATION THROUGH COMPUTER PROGRAM

摘要

It provides a method for managing the remaining life of a high temperatu re component used in a gas turbine that enables a state of fatigue of a high temperature component to be evaluated and controlled with a high level of accuracy, and a program medium for performing the method for managing the remaining life of a high temperature gas turbine component on a computer. In the method for managing the lifespan of a high temperature component used in a gas turbine, the lifespan of a high temperature component being evaluated is set within an operating area bounded by a component life limit line that is determined on the basis of field data giving the correlation between the operating time and operating cycles for the state of fatigue from past high temperature components. As the program medium, a medium is employed that is provided wit h a program in which this method is used for managing a lifespan of a high temperature component used in a gas turbine.
