Abstract

Most developed and developing countries are becoming increasingly aware of the limited energy resources, which is why they develop strategies and establish stringent processes to address this problem. In this study, a thermodynamic parametric analysis was conducted for a real case of a gas turbine power plant located in India. The investigation yields energy engineering recommendations for the real case study, ultimately reducing fuel consumption while enhancing overall power plant performance. The elaborated model examines all relevant compartments in the gas turbine cycle from the perspectives of energy, exergy, and exergy destruction. The results revealed that the combustion chamber accounted for the highest exergy destruction, amounting to 82.28%. The compressor followed this at 8.10% and the turbine at 6.10%. The overall energy and Exergy Efficiencies of the system were determined to be 28.8% and 27.17%, respectively. The exergy efficiencies of the air compressor, combustion chamber, and gas turbine are 97.2%, 50.3%, and 93.3%, respectively. The exergy destruction efficiencies of the air compressor, combustion chamber, and gas turbine are 8.1%, 82.28%, and 6.10%, respectively. As the temperature increases, more exergy is lost, leading to lower efficiency and reduced net power output. Therefore, optimising the design of the combustion chamber is essential to counteract the negative effects of hot weather. The insights gained from this study can be used to improve the design and operation of gas turbine plants in hot climates.
