TT04 - Performance of Industrial Gas Turbines--Tutorial
MetadataShow full item record
Industrial gas turbines have performance characteristics that distinctly depend on ambient and operating conditions. Application of these gas turbines, as well as the control and condition monitoring, require to consider the influence of site elevation, ambient temperature and relative humidity, the speed of the driven equipment, the fuel, and the load conditions. The reasons for these performance characteristics can be explained by the behavior the gas turbine components and their interaction. The tutorial explains the performance characteristics based on the performance of the engine compressor, the combustor and the turbine section, and certain control strategies. It introduces fundamental concepts that help to understand the flow of energy between the components. Further discussed are control concepts, both for single shaft and two shaft machines, driving generators, compressors, or pumps. Methods are introduced that allow to use performance data for trending and comparison purposes. The impact of component degradation on individual component performance, as well as overall engine performance is discussed, together with strategies to reduce the impact of degradation.
