Enhancing Gas Turbine Performance with Fogging Inlet Air Cooling at Western Mountain Power Plant

Abstract

Gas turbine power plants are highly sensitive to environmental conditions, especially in hot climates. Fogging is one of the most effective methods for lowering the air temperature in rooms and greenhouses. This research focuses on the use of a fogging inlet cooling system to improve the performance of the Western Mountain Gas Power Plant. The Western Mountain Gas Power Plant is supplied with gas from the Wafa-Mellitah line. HYSYS Aspen program was used to simulate the real data collected from the Western Mountain Power Plant for the second unit gas turbine using the fogging inlet cooling system to cool the air and without installing the system.

The results showed a decrease in the temperature rate of the inlet air by 7% in the case of the presence of the fogging inlet cooling system. In addition, an increase in net power from 131.5 to 143.1 MW resulted in improving efficiency from 35.36% to 38.5% and a total of 4,952,028 kg of greenhouse gases was saved. [1,3].
