The purpose of a wet layup in a boiler is specifically for long-term shutdown maintenance. This process involves filling the boiler with water and treating that water with chemicals to prevent corrosion and scale buildup during the period when the boiler is not in use. The water creates a barrier to protect metal surfaces from the atmosphere, reducing the risk of oxidation and deterioration that could occur if the boiler were left dry or open to air.

During a wet layup, proper monitoring and maintenance of water chemistry are essential to ensure that the protective measures remain effective. This procedure is critical for maintaining the integrity of the boiler so that when it is re-commissioned, it can operate safely and efficiently without needing extensive repairs or cleaning. Understanding the specific terms associated with boiler maintenance helps in recognizing the best practices for ensuring equipment longevity, especially during prolonged periods of inactivity.
