The thesis focuses on the evaluation and improvement of a gas-turbine based co-generation system, from an exergetic point of view. A conventional exergy analysis has some limitations, which are significantly reduced by an advanced exergy analysis. This analysis evaluates:
(a) the interactions among components of the overall system (splitting the exergy destruction into endogenous and exogenous parts), and
(b) the real potential for improving a system component (splitting the exergy destruction into unavoidable and avoidable parts).
The main role of an advanced exergy analysis is to provide engineers with information useful for improving the design and operation of energy conversion systems.
