Boilers are often damaged by corrosion during out-of-service periods. Idle boilers are very vulnerable to attack when air (21% oxygen) contacts moist metal surfaces. To prevent corrosion, the boiler metal must be protected by either keeping the surfaces completely dry or excluding all air from the boiler by completely filling it with properly treated water.
