What is the main purpose of a condensate polishing system?

The main purpose of a condensate polishing system is to remove a small amount of contaminants from condensate. This process is crucial in maintaining the quality of the water that returns to the boiler. Contaminants in the condensate, such as dissolved solids, oils, and chemicals, can lead to issues like corrosion, scaling, and reduced efficiency in the boiler system. By effectively polishing the condensate, the system ensures that the water quality is high enough to prevent these problems, which can result in costly repairs and downtime.

In a power plant, maintaining the purity of the steam and water cycle is vital for optimal operational performance, and that is where the condensate polishing system plays a critical role. It allows the mechanical and chemical integrity of the boiler and turbine systems to be preserved over time, promoting longevity and efficiency.
