Development of Gas Turbine Hot Gas Path Parts Maintenance Planning Support System

摘要

Since the hot gas path parts such as combustors, blades, and vanes positioned in the hot gas path are subjected to extremely severe working conditions, the parts must be inspected and repaired at relatively short intervals. Therefore, it is essential to reduce the maintenance costs for economic reasons. Furthermore, since the hot gas path parts have cooling structures with advanced design and coated with various types of coatings, the prices of parts are usually very high. Therefore, using the parts efficiently and implementing to extend the service life of the parts are needed to significantly reduce the maintenance costs. In such a situation, a platform free system of. "Gas Turbine Hot Gas Path Parts Maintenance Planning Support System" has been developed. This system can be used to decrease parts disposal loss by optimizing parts rotation plans.
