Combined cycle power plants are among the most efficient methods of electricity generation, utilizing a combination of gas and steam cycles to enhance energy efficiency. A crucial component in these power plants is the air-cooled condenser (ACC), which plays a significant role in cooling and converting the exhaust steam from the steam turbine back into water. However, the efficiency of air-cooled condensers is highly influenced by environmental conditions, particularly air temperature, humidity and wind speed, which can lead to a reduction in the overall efficiency of the power plant. This paper examines methods for improving the performance of air-cooled condensers in combined cycle power plants. It first addresses the challenges associated with the design and operation of these condensers under varying environmental conditions. Next, innovative solutions such as changing the angle of the blades, creating water spray paths at the inlet of the blades, and the washing of fin tubes and the evaluation of wind speed reduction methods are analyzed. The findings indicate that by adopting these strategies, it is possible to enhance the thermal efficiency of the power plant, reduce water consumption, and minimize operational costs. Recommendations for future research in the optimization and development of cooling technologies are also provided.
