Abstract

In this study, we conducted a comparative evaluation of the performance of oil-water heat exchangers in a thermal power plant after the installation of 32 magnetic conditioning devices across the four shell and tube heat exchangers in operation. The thermal assessment of the shell and tube was based on system operating parameters, using the logarithmic temperature difference and effectiveness-NTU method. The key outcome after implementing these magnetic conditioning devices was more than 20% increase in system effectiveness compare to pre-installation levels. The operation of heat exchangers with nominal working parameters, since the installation of magnetic devices in January 2024, has enabled their safe and stable operation. These elements have made it possible to extend maintenance periods, contributing to the energy efficiency of the industry
