WebFouling in a heat exchanger can take several forms: 1. Scaling. Scaling, also known as crystallization fouling, is particularly common, especially in systems involving water. Scaling occurs when minerals in the water precipitate and collect on the heat exchanger’s surfaces as crystals, forming a whitish buildup. 2. Particulate Fouling WebScale and Fouling, which is a result of “Hardness” in water, is most often caused by calcium carbonate, calcium phosphate, or magnesium silicate. These compounds will precipitate …
