Name a common way to prevent boiler corrosion.

Maintaining proper water treatment and pH levels is essential in preventing boiler corrosion because the quality of water directly impacts the integrity of the boiler system. When water contains impurities such as dissolved oxygen, carbon dioxide, or high levels of hardness, it can lead to various forms of corrosion including pitting and scaling.

Proper water treatment involves the use of chemicals to neutralize harmful elements, controlling the pH balance to maintain an optimal level. The ideal pH range generally falls between 10.5 to 11.5 for most boiler systems. This range helps to create a protective layer on the metal surfaces, reducing the likelihood of corrosion. Regular testing and adjustments of water chemistry can effectively minimize the risk of corrosion and extend the lifespan of the boiler.

Other methods may have some effect on boiler maintenance, but they do not directly address the corrosive potential of the water used in the system. For example, using plastic parts may help limit metal corrosion but is not a feasible solution for the majority of boiler components due to strength and thermal properties. Regularly replacing the boiler could be expensive and inefficient compared to properly maintaining water chemistry. Additionally, avoiding water interaction with the boiler is impractical since water is the main medium for heat exchange in a boiler system.
