Abstract

Gas turbines are among the essential power generation machines. One of the main disadvantages of the gas turbines is reduced power and efficiency due to the increased ambient temperature. In other words, when the ambient temperature rises in hot seasons, the air mass flow rate into a gas turbine decreases due to the reduction of air density. In order to compensate for reduction of air mass flow rate in hot seasons, an external compressor can be included in the cycle. Injection of air flow rate into the cycle by the external compressor can compensate for the reduction of the turbine flow and increase the pressure ratios of the turbine and the main compressor. As a result, by changing the operating point of the main compressor, the air mass flow rate of the air passing through the main compressor is reduced. Using trial and error technique, new flow rate of the main compressor was calculated. Finally, the total airflow rate of the gas turbine and the total power and efficiency of the cycle increased since an external compressor raised the total airflow rate of the gas turbine.
