How can corrosion in feed water and condensate systems be prevented?

To effectively prevent corrosion in feed water and condensate systems, the addition of ammonia-based products is crucial. Ammonia helps in controlling pH levels within the water. By raising the pH, ammonia reduces the corrosiveness of the water, creating a more favorable environment for the metal surfaces in the system, thus minimizing the likelihood of corrosion.

When the pH of the water is adequately managed, it reduces the solubility of corrosion-causing compounds and adheres to a basic principle of water treatment. This method not only minimizes the aggressive nature of carbon dioxide and oxygen, which contribute to corrosion, but also aids in forming a protective layer on metal surfaces that resists corrosion.

Others might suggest that the use of acid-based solutions could potentially raise issues rather than solving them, as they may lower pH levels and increase the likelihood of corrosion. Galvanized materials, typically made by coating steel with zinc, may not be ideal for high-temperature applications or in systems involving steam where water chemistry is critical. Cathodic protection is also an effective method for preventing corrosion, particularly for exposed and submerged metals, but it involves a more complex implementation process and may not be practical for all feed water and condensate systems.

Thus, the use of ammonia
