Abstract
The present application provides a method of evaluating valve creep damage in a turbine by a data acquisition system. The method may include the steps of receiving a number of operating parameters from a number of sensors including steam temperatures and steam pressures about the valve over time, generating a design material model for the valve, determining an indicator for consumed creep lifetime based on the steam temperature and steam pressures about the valve over time as compared to the design material model, and altering one or more of the operating parameters and/or initiating repair procedures based upon the consumed creep lifetime indicator.
