Evaporative Cooler As an Air Inlet Treatment Of Gas Turbine

This author is studying the air inlet treatment of gas turbine. This is due to the problem of
lower efficiency of gas turbine when deal with the hot and dry air. This problem also
rises in the CUF Kertih, Terengganu power plant. The gas turbine cannot achieve the
maximum power output. The performance of a gas turbine varies significantly with
ambient air temperature. As the air temperature rises, its density decreases, resulting in
reduced mass flow through the compressor and turbine, thereby causing a corresponding
reduction in turbine output. Actually, nowadays many technologies are used in the world
regarding the cooling air inlet gas turbines. They have proved that this kind air treatment
can increase the power output capacity. In this project, author will be studying on existing
technologies out there used in the industry and discuss the most common technologies
used. Make some analysis and comparison of each technology. The selected system is
evaporative cooler. Evaporative cooler is the most widely used technology in the world in
order increase the power output of the gas turbine. This is the most cost effective
technology being used in the power plants. In fact, in hot and humid regions, it often isn't
possible to accomplish more than about -9 to -l2°C of cooling. The experiment was
carried out with the evaporative cooler prototype in order to make some data analysis.
The result show that evaporative cooler reduced the inlet temperature hence increased the
power output of gas turbine.
