What is the primary purpose of external feedwater treatment in boiler systems?

The primary purpose of external feedwater treatment in boiler systems is to reduce solids and other pollutants in the water. This treatment process is crucial because the quality of the feedwater directly affects the efficiency and longevity of the boiler.

When water enters a boiler, impurities such as minerals, organic matter, and other contaminants can lead to several problems, including scaling, corrosion, and fouling. By treating the feedwater to remove these solids and pollutants, operators can minimize these issues, thus ensuring smoother operation, maintaining heat transfer efficiency, and preventing breakdowns. Adequate feedwater treatment helps in producing high-quality steam, which is essential for the effective functioning of any industrial boiler system.
