Effect of air-fuel ratio and pressure ratio on the exergetic performance of combined cycle gas turbine plant components

The performance of a combined cycle gas turbine power plant depends on multiple operating parameters, which are influential in distinct ways. These parameters classified as and steam parameters. This paper deals with the influence two i.e., pressure ratio air-fuel ratio. 2nd law thermodynamics has been taken into consideration along energy analysis to measure several components plant. Therefore, comprehensive exergy for each element carried out overserve trend given range aforementioned It is observed from results that destruction increases compressor at higher-pressure if subjected increased airflow, but exergetic efficiency remains unchanged. Moreover, similar increment combustion chamber, rate change varies increase Air-fuel For lower ratios (5-10), decreases increasing proportion, effect becomes nearly opposite ratios.
