Abstract
In this paper, the dew point indirect evaporative cooling was used as the cooling method for inlet air based on the Maisotsenko cycle to study the gas turbine performance improvement under different environmental conditions.A thermodynamic calculation model for a 9E gas turbine was established, and the effect of the change of inlet temperature on the output capacity of gas turbine was analyzed through the thermodynamic model. Based on the theory of Maisotsenko cycle, performance of dew point indirect evaporative cooler was analyzed from the aspect of temperature drop.The output power and efficiency were taken as performance indexes, and the gas turbine performance under different environmental conditions was numerically studied. Three different methods for inlet air cooling were compared, including no inlet cooling, direct spraying cooling, and the dew point indirect evaporative cooling based on Maisotsenko cycle.The results showed that the dew point indirect evaporative cooling based on Maisotsenko cycle can effectively improve the performance of gas turbine under the condition of high temperature and low humidity.
