| Abstract | ||
| In the hot regions the demand on electricity increased in the hot months. Gas turbine power plant is a good solution for this problem, since it has low cost, low time of installation and stable with electricity grid variation. But the power output of gas turbine is affected by the ambient temperature, the power decrease by 18% when the ambient temperature increase to 40oc. Inlet air cooling methods are used to boost the power losses in the hot days. In the present study a thermally and economically analysis was performed for Al-Rumaila gas turbine power plant located in Basrah (south of Iraq). The plant consist from five units and each unit designed to generates 296MW.The results shows that, the maximum decrease in the power developed due the increase in ambient air temperature reaches 22.97% during the month of July. The percentage of power saving due inlet air cooling increased with increasing the ambient air temperature. | ||
