The Sometimes Maddening Question of Boiler Lay-Up

The preferred choice for boiler lay-up is dry lay-up. Removing boiler water/moisture and preventing new sources of moisture from forming are essential to good dry boiler lay-up and is the best way to prevent offline corrosion. This accomplished by draining the water from the boiler while it is still hot and under 25 – 50 psi of system pressure.

In each application, be sure to consider the boiler Load Factor, the efficiency that the hot water is otherwise produced at, the cost of natural gas, and the installation cost of the equipment. If the economizer would be used to heat boiler make-up water, it is necessary to determine the volume and temperature at the inlet of the economizer.
