Abstract

Gas turbines are widely used in electric power plants all over the world to generate energy. High temperatures affect the gas turbine’s efficiency. When the air temperature around the gas turbine ranges from approximately 40‒50°C, the efficiency and output power will decrease, due to the decrease in air density mass. The study of gas turbines was conducted at the Al-Quds Gas Station in Baghdad, Iraq, a city known for hot summers. A combination of Turbine Air Intake Cooling Systems (TIACS) is typically used to help cool the inlet air of a gas turbine. This study investigates of fogging cooling system (upstream), a new cooling technology to cool the air entering the turbine resulting in improved gas turbine performance and increased turbine efficiency. The two main parts of the indirect technology are the use of pipeline heat exchangers that deliver the water to the nozzle and nanoparticles Nano-Aluminum Oxide (Al2O3) to cool the water tank for heat exchange which cools the air entering the turbine. The results concluded the amount of efficiency produced increases when the water temperature in the pipe drops to 25°C and the air’s temperature upon entry the compressor is reduced by 12°C the water temperature for the sprinklers 25°C, the temperature value of the air entering the gas turbine decreased to 14°C by 1.68%.
