What is the recommended action for boiler lay-ups when transitioning to hydrazine?

• A. Increase temperature
• B. Change water source
• C. Conduct a full dump
• D. Regularly check water levels

Answer: (C)

The recommended action for boiler lay-ups when transitioning to hydrazine involves conducting a full dump. This practice is critical because it helps to remove any residual contaminants and impurities from the boiler system, which is especially important when introducing hydrazine as a corrosion inhibitor. Hydrazine is sensitive to the presence of certain contaminants, and a full dump ensures that the boiler is clean and ready for the safe and effective use of hydrazine. By performing a full dump, the risk of chemical interactions that could lead to corrosion or damage to the boiler system is minimized. It sets the stage for a clean environment in which hydrazine can effectively protect the system against oxidation and scale buildup, thereby extending the boiler's operational lifespan. While increasing temperature, changing water source, or regularly checking water levels may be important steps in boiler maintenance and operation, they do not specifically address the need for a thorough cleaning of the system before adding hydrazine. Hence, these actions are not the recommended first step during this transition.
