Powder Coated System for Yulin Subcritical Power Plant (5X330MW)
A typical project of powder coated filter applied in high temperature condensate polishing system.

SafBon applied an advanced powder coated filter in the condensate polishing system for Yulin power plant. The water resource is deficient in the Chinese northern area, so the new built power plants adopt air cooling units, which results in a high temperature of the condensate. The application of SafBon powder coated filters solved the technical difficulty that the hot condensate cannot be treated with the conventional deep bed polishing.
