Why is monitoring the pH level important in feedwater quality assessment?

Monitoring the pH level in feedwater is crucial because it directly influences the corrosion rates of materials used in the boiler system and other auxiliary equipment. A pH level that is outside the optimal range can lead to corrosive conditions, potentially damaging pipes, boilers, and other components over time. For instance, if the pH is too low (acidic), it can accelerate the corrosion of metal surfaces, leading to leaks and equipment failure. Conversely, if the pH is too high (alkaline), it can also cause issues such as scaling, which can hinder heat transfer and reduce system efficiency. Therefore, maintaining the appropriate pH balance is essential for the longevity and safe operation of the feedwater system.
