How is a condensate polishing unit used in boilers?

A condensate polishing unit in boilers is used to purify the return condensate before it is fed back into the boiler. During the steam cycle, impurities such as dissolved salts and suspended solids can accumulate in the condensate. The polishing unit removes these impurities, preventing scale buildup and corrosion inside the boiler. This ensures that the water used in the steam generation process is of high quality, maintaining the efficiency and longevity of the boiler. Regular maintenance of the condensate polishing unit, including filter replacement and resin regeneration, is essential for optimal performance.
