INFLUÊNCIA DE INCRUSTAÇÕES NA EFICIÊNCIA DE TROCADORES DE CALOR: O CASO DA PERDA DE PRODUTIVIDADE EM HIDRELÉTRICAS

Abstract

Heat exchangers are widely used in industrial processes and various applications. In hydroelectric power plants, they are essential for cooling key components, employing open cooling systems that draw water directly from reservoirs. However, this method can lead to fouling buildup, reducing equipment efficiency and impacting productivity. This study evaluated whether the application of an automated mechanical cleaning process could minimize or eliminate efficiency loss in heat exchangers used in hydro generator cooling systems. The research showed that periodic removal of fouling significantly improves thermal efficiency and reduces unplanned shutdowns in hydroelectric plants.
