Performance Modeling and Simulation of a Micro Gas Turbine for Power Generation

This paper presents and analyzes the performance of a micro gas turbine (MGT) producing constant power using compressor and turbine maps of the studied case. Simulation program of a MGT was validated by using a commercial process simulator. In this simulator, MGT components were modeled individually and the thermodynamic properties of air and combustion gases were estimated. Also, important information such as inlet gas mass flow rate, fuel to air ratio, thermal efficiency, and exhaust gas temperature were obtained during increment in ambient temperature for a constant load. This information could be useful to install MGTs in different ambient temperatures when continuous constant power is required and to design exhaust gas fired absorption chillers which use the heat of the exhaust gas of MGT. Finally, the equilibrium running line of the compressor of the MGT was derived
