Which component of the boiler system helps maintain the dry condition of the system during lay-up?

• A. Heat exchangers
• B. Stack covers
• C. Exhaust fans
• D. Condensers

Answer: (B)

The correct answer is stack covers, as they play a critical role in protecting the boiler system during lay-up by preventing moisture from entering the system. During periods when the boiler is not in operation, maintaining a dry environment is crucial to prevent corrosion and deterioration of the internal components. Stack covers effectively seal off the flue gas outlet of the boiler, ensuring that rainwater and other sources of moisture do not accumulate within the boiler or its associated components. This helps to maintain a dry condition and protects the integrity of the system, which is essential for its longevity, efficiency, and safety when it’s put back into service. The other components listed do not provide the same protective measure specifically against moisture intrusion. Heat exchangers, exhaust fans, and condensers are designed for different purposes within the boiler system, such as transferring heat or managing airflow, but they do not serve the direct function of preventing moisture entry during lay-up periods.
