Title: SOLID PARTICLE EROSION INDICATOR MODULE FOR A VALVE AND ACTUATOR MONITORING SYSTEM
Abstract:
The present application provides a method of evaluating valve conditions 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, wherein the operating parameters may include steam temperatures determined over time and steam pressure, determining a steam chemistry, a throttling history, and a piping material, determining a probability of valve erosion based upon the steam temperatures determined over time, the steam chemistry, the throttling history, and the piping material, and altering one or more of the operating parameters and/or initiating repair procedures based upon the determined probability.
