Excess dissolved oxygen in water is a significant contributor to boiler corrosion. When oxygen is present in the boiler feedwater, it can lead to the formation of corrosive compounds, particularly in the presence of heat. The dissolved oxygen reacts with the metal surfaces of the boiler, which accelerates the oxidation process and can result in pitting and weakening of the metal. This corrosion not only threatens the integrity of the boiler system but can also lead to costly repairs and maintenance issues.

In contrast, high water temperature can actually reduce the solubility of gases like oxygen, thus minimizing the potential for corrosion. Low pressure conditions may not directly cause corrosion; rather, they can create conditions where other factors might influence corrosion rates. Proper fuel combustion, on the other hand, is related to overall efficiency and safety of the boiler operation, rather than directly contributing to any form of corrosion. Understanding the role of dissolved oxygen in boiler systems is essential for ensuring proper maintenance and prolonging the lifespan of the equipment.
