Advanced Exergy and Exergoeconomic Analysis of a Gas Power System with Steam Injection and Air Cooling with a Compression Refrigeration Machine

Gas turbine power plants have been widely studied, and as a result the negative effects on their output thermal efficiency known when operating in atmospheric conditions exceeding ISO conditions. For this reason, different technologies methodologies implemented, aiming to increase improve efficiency. Unfortunately, lack of operational parameters for system limited its characterization implementation strategies performance. Advanced exergetic exergoeconomic analyses applied energy economic performance steam injection gas (STIG) cycle with air cooling compression refrigeration machine. Results shows that main sources irreversibilities higher costs are Combustion Chamber (CC), Heat Recovery Steam Generator (HRSG) Turbine (GT). From these components, components HRSG GT greatest potential improvement, can be achieved by improving overall configuration system, due fact destruction exogenous exergy is more significant measure avoidable. While investment reduced Turbine.
