Abstract
The standard conditions used for the design of gas turbines are 15o C, sea level atmospheric pressure and 60% relative humidity. In Abu Dhabi, the performance of gas-turbine power plants is therefore affected by its specific atmospheric conditions since they are different from the ISO requirements. The main objective of this research work was to conduct an exergy analysis for a power-generation plant in Abu Dhabi (UAE) in order to investigate the effects of high temperatures and absolute humidity of ambient air on its performance. Our data showed that the temperature had more negative effects on the performance of the plant than the absolute humidity and the combustion chamber was the main source of irreversibility (70.2%). On the other hand, the compressor had the lowest contribution of exergy destruction (12.4%). Compared to the design conditions (T=15o C, RH=60%), our results indicated that in summer conditions (T=43o C, RH=50%), the power plant lost 4.66% of its net power output and 4.61% of its exergy efficiency.
