METHOD AND APPARATUS FOR ASSESSING THE IMPACT OF INDIVIDUAL PARTS OF A GAS TURBINE COMPONENT ON THE OVERALL THERMAL PERFORMANCE OF A GAS TURBINE

摘要

A method of determining performance impact of a gas turbine components (202, 204, 206) on overall thermal performance of a gas turbine (200). The method includes obtaining measured physical condition data for a select gas turbine component parts (301-306). The measured physical condition data is compared with a predetermined reference value for the select gas turbine component part to determine a deviation of the measured physical condition data with respect to the predetermined reference value. The impact of the deviation on the overall thermal performance of the gas turbine is subsequently determined.
