Adding Sodium Sulfite to the boiler water.

Sodium sulfite is an oxygen scavenger — it chemically reacts with dissolved O2 (forming sulfate) and prevents oxygen pitting/corrosion. Filtration, blowdown of sludge, or eliminating water-level fluctuations do not remove dissolved oxygen (deaeration or oxygen scavengers are required).
