What occurs if the corrosion resistor completely corrodes away?

• A. Corrosion halts
• B. Corrosion starts on the boiler shell
• C. Only the anode remains
• D. It begins to repair itself

Answer: (B)

When the corrosion resistor completely corrodes away, the protective layer that was providing a buffer against corrosion is no longer present. As a result, the surface of the boiler shell becomes directly exposed to the corrosive environment, which can lead to accelerated corrosion on the boiler shell itself. This means that without the corrosion resistor's protective effects, the underlying metal is vulnerable to the same corrosive agents that previously affected the resistor, leading to potential structural damage and reduced longevity of the boiler. This situation highlights the importance of the corrosion resistor in maintaining the integrity of the boiler system.
