Integration of High-Pressure Fogging Air Intake Cooling System in a Gas Turbine Powered Plant

Abstract

It is suggested that one way to increase a gas turbine power plant's power output is to reduce the air intake to the compressor by incorporating a high-pressure fogging system, which is one of the air intake cooling technologies. This study's methodology entails simulating a gas turbine power plant system without cooling, then incorporating cooling systems into the gas turbine system using the plant's actual operating data and comparing their performance. Aspen HYSYS simulation software was used. The findings of simulating a simple system gas turbine at 25.690 °C ambient air temperature revealed that the temperature of the surrounding air raises the specific fuel consumption and heat rate while decreasing net power output and thermal efficiency. Furthermore, data indicated that the addition of high-pressure fogging to the simple system gas turbine resulted in a decrease in the ambient air temperature (17.010 °C), which raised the thermal efficiency of the net power production and decreased the specific fuel consumption and heat rate.
