RE: Boiler Wet Preservation-alternative to hydrazine?
If you have a means for mechanical removal of oxygen from feedwater like a DC heater during normal operation, you can fill the boiler full with de-oxygenated feedwater and use a nitrogen blanket for wet lay-up. Hydrazine in feedwater under ambient temperature conditions will not be effective.
OR, use a nitrogen sparger system to feed nitrogen into the feedwater and vent the excess nitrogen out the top of the boiler. You would need a continual supply of nitrogen until the dissolved oxygen level drops and you close the vent and bottle up the boiler with nitrogen.

Here is just one of several paper from Cortec concerning the wet lay up of boilers.
