11/15/2012 · Corrosion of the boiler internal surfaces not only weakens the integrity of the system, but also releases iron oxides into the boiler water. While not a concern when the boiler system is offline, iron scaling can be a concern after start-up as these iron oxides produced during lay-up can deposit on steam generating tubes. Lay-Up Methods Dry Lay-Up
The boiler steam line will thus be warmed up with steam flowing back from the steam header. Any condensate present will be forced out the drain valve. The header valve can be slowly opened wide when the pressure has equalized between the steam header and the boiler steam line.
