What is the role of condensate polishing in power plants?

In power plants, condensate polishing plays a crucial role in maintaining the efficiency and longevity of equipment by purifying the condensate used in steam cycles. As steam is condensed and returned to the boiler, it can carry impurities such as dissolved salts, corrosion products, and suspended solids. These impurities can cause scaling, corrosion, and fouling of boiler and turbine components. By using condensate polishing systems, power plants remove these impurities, ensuring the condensate is clean and suitable for reuse, thereby improving the reliability and efficiency of the steam cycle.
