Abstract

the research aims to Explain the importance of increasing the efficiency of gas turbine stations by using part of the exhaust gas and how to apply this to raising the efficiency of the gas turbine station by using a reheated and a heat exchanger before the combustion chamber and using the combined cycle, and comparing them in terms of efficiency, in terms of operating cost, in terms of life span. Invasive through methodology combines description, application, and analysis methodologies using simulation technology. The results indicated that the heat exchanger reheating method increased the efficiency at a rate ranging from five to 15%, the cost of increasing the efficiency was 33.1%, and the life expectancy of the station was 23years. In comparison, the combined cycle method cost 34.5% and increased the efficiency by a rate ranging from 6% to 18%. The expected lifespan is 22 years, while the emissions rate in the first method was 20% better than the second method.
