What is the primary purpose of using a dry lay-up method for a boiler?

• A. Enhance steam production
• B. Reduce water content
• C. Minimize chemical treatment
• D. Prevent corrosion

Answer: (D)

The primary purpose of using a dry lay-up method for a boiler is to prevent corrosion. This method involves emptying the boiler of water and allowing it to dry, which significantly reduces the risk of corrosion that can occur when metal surfaces are exposed to moisture over time. When water is removed and the surfaces are allowed to remain dry, the conditions that promote rust and corrosion are greatly diminished. This is crucial for maintaining the integrity and longevity of the boiler, as corrosion can lead to serious structural issues and ultimately affect the boiler's operation and safety. In contrast, while options like enhancing steam production, reducing water content, and minimizing chemical treatment relate to boiler operation and maintenance, they do not specifically address the fundamental need to protect the boiler's materials from damage due to oxidation and corrosion during periods when the boiler is not in service.
