What is the effect of having too much make-up water in a boiler system?

• A. Increased efficiency
• B. Higher corrosion rates
• C. Lower fuel consumption
• D. Better heat retention

Answer: (B)

Having too much make-up water in a boiler system introduces several issues related to water quality and chemistry. One of the primary consequences is the increase in corrosion rates within the system. When make-up water—especially if it is not properly treated—contains dissolved oxygen, carbon dioxide, and other impurities, it can lead to the formation of corrosion-causing compounds upon contact with boiler metal surfaces.

Corrosion is especially problematic in boiler systems because it can damage pipes and components, leading to leaks, reduced efficiency, and potentially catastrophic failure. The presence of excess make-up water can dilute the concentration of protective chemicals meant to prevent scale and corrosion, further promoting these detrimental processes.

Additionally, while the other options may seem advantageous or neutral, they do not effectively address the core issue associated with excessive make-up water, which is the negative impact on the integrity and longevity of the boiler system. Thus, understanding the implications of water quality in boiler operations is crucial for maintaining system performance and safety.
