The Thermodynamic Study and Increasing the Efficiency of a Gas Turbine by Recovery of Exhaust Gases

Among the various means of producing mechanical energy, turbines are in many ways the most satisfying. The gas turbine is the most versatile item of turbo-machinery today. It can be used in several different modes in critical industries such as power generation, oil and gas, process plants, and aviation. The thermal efficiency of gas turbines, often referred to as the ratio of useful work output to the heat input, is a key performance parameter that directly impacts their economic and environmental viability. This paper presents an overview of the factor influencing the thermal efficiency of gas turbines, and the performance optimization strategy employed to enhance it. On this basis, the efficiency of the GT with regeneration will be evaluated to compare them and draw conclusions regarding the potential gains that can be made with regeneration. Furthermore, it highlights the significance of thermal efficiency improvements in reducing fuel consumption, greenhouse gas emissions, and operating costs.
