Gas Turbine Performance and Maintenance
MetadataShow full item record
In this tutorial, we will address the basic characteristics of each of the components in a gas turbine (compressor, combustor, gas generator turbine, power turbine) and the impact of typical control limits and control concepts. The power and efficiency characteristics of a gas turbine are the result of a complex interaction of different turbo machines and a combustion system The goal is to provide explanations for the operational characteristics of typical industrial gas turbines, emphasizing the interaction between the gas turbine components. The concept of component matching is explained. Methods are introduced that allow the use of 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, and to maintain the high performance levels of the engine. Fuel types, and typical issues arising from the use of certain fuels , as well as the importance of appropriate gas turbine inlet air filtration are addressed. The concepts developed will be used to derive basic principles for successful condition monitoring and performance testing of gas turbines.
