Abstract:An analysis is done by the use of thermodynamics for an aero derivative gas turbine which utilizes steam injection to increase its efficiency. This type of cycle is known as the steam injected gas turbine cycle. The main purpose of this research was to develop a better understanding of how optimal cycle efficiency is reached, for which the steam of injection is generated by use of the turbine exhaust heat. A model has been developed using the software Engineering Equation Solver to simulate the simple gas turbine, steam generation and effects after steam injection. Input parameters for the model are taken for the GE LM6000 turbine as provided by General Electric. Turbine property results are compared with literature for validation and show the same characteristic behaviour. Several parameter influences are visualized and explained. It has been found that this type of cycle shows a very specific point where the efficiency is the highest. By using steam injection for the chosen turbine and parameters an efficiency gains of around 11% and power augmentation of 45% is possible to be achieved.
