What can be a consequence of high dissolved oxygen levels in feedwater?

High dissolved oxygen levels in feedwater can lead to an increased risk of corrosion within the boiler and piping systems. Dissolved oxygen is highly reactive, and when it combines with the metal surfaces of the equipment, it can form oxides, leading to pitting and other forms of corrosion. This deterioration can significantly impact the lifespan and operational efficiency of the equipment, resulting in costly repairs and maintenance.

In contrast, improved thermal efficiency, reduced water treatment costs, and enhanced steam quality do not typically result from high dissolved oxygen levels. These factors are generally associated with lower levels of dissolved oxygen, as effective water treatment is aimed at minimizing oxygen to protect against corrosion and maintain overall system integrity.
