What problem does dissolved oxygen in condensate primarily cause?

Dissolved oxygen in condensate is a significant concern primarily because it contributes to corrosion within the boiler system. When oxygen is present in the water, it reacts with the metal surfaces of the boiler components, leading to the formation of rust and other corrosive materials. This process can weaken the metal over time, potentially causing leaks or even catastrophic boiler failures.

Controlling dissolved oxygen levels through proper treatment methods is crucial in boiler water management, ensuring that the system remains efficient and has a longer operational life. Techniques such as degasification, chemical treatment with oxygen scavengers, and maintaining proper water chemistry are commonly employed to minimize the risk of corrosion associated with dissolved oxygen.
