CORROSION INHIBITORS – Boiler Systems (Amines & Oxygen

In order to remove the remaining oxygen and provide the boiler with high-purity feedwater, the application of an oxygen scavenger is utilized. Additionally, applying chemical oxygen scavengers indirectly leads to passivated metal surfaces and lower amounts of metal oxide that is transported to the boiler.

oxygen scavengers. Oxygen scavengers are reducing agents that react with even the very low levels of oxygen left in water by good deaeration. They are normally added to the storage section of the deaerator, to allow time for reaction before the feedwater reaches the boiler. Low pressure boilers sometimes do not include mechanical deaerators. In
