Recently the number of gan-turbine-powered, combined-cycle plants has been increasing because of their environmental compatibility and high efficiency.Gas turbine operating conditions are severe, especially for hot gas path components.To improve the reliability and extend the life of such components, a life management system has been developed that is based on a residual life assessment method.The system makes possible integrated residual life assessment based on numerical analyses, material destructive-tests, nondestructive inspections, statistical analyses of field machine data, and use of a database.The primary damage mechanism for each component is clarified and material degradation is evaluated.For nozzles, the system describes a method of predicting the maximum surface crack growth.The validity of the methods is verified by assessment of the inspection data.This paper also describes optimization of operating cost and RAM(reliability, availability and maintainability).
