Abstract
TutorialsIn 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
