摘要： A method is disclosed for providing a real time, radial exhaust temperature distribution in a gas turbine to improve the understanding of exhaust gas temperature in a manner similar to installing production rakes. The thermocouples are installed along the exhaust frame strut skins at a number of radial positions. The data from the thermocouples along each of the struts is used to produce a normalized radial profile of the turbine exhaust temperature. The existing turbine station instrumentation is then used to expand the normalized profile into an actual profile of the turbine exhaust temperature. The calculations/transfer functions for temperatures are obtained from data collected during performance testing with full rakes. This profile is integrated to determine a bulk Tx to improve gas turbine controls including model-based controls or corrected parameter controls (MBC/CPC) controls, or specific radial temperatures are used, to provide protective action for bucket platforms, or other turbine components.

摘要： Maintenance operations for a hot gas path of a gas turbine require shutdown and cooled down conditions. When a gas turbine is shut down, thermal gradients in the rotor cause stresses that limit the life of the major components. As the cooling rate is increased to reduce the time, the stresses are increased, reducing rotor life. A method and equipment are provided to reduce the overall cycle time for the maintenance, yet mitigate the life penalties, thereby providing greater power production while maintaining (or potentially extending) rotor life. The method includes small hold times during the turbine shutdown and startup and slower turbine ramp rates during cooldown and startup, which more than offset thermal stresses from a forced cooldown, considerably shortening the overall operation.
