Boiler Oxygen Scavengers are used to remove dissolved oxygen from the boiler feed water and boilers. Dissolved oxygen in the boiler is very corrosive at higher temperatures and pressures. This may lead to localized pitting and premature boiler tube failure or excessive feedwater leaks.
What is Boiler Oxygen Scavengers? The most common boiler oxygen scavenger is sodium sulfite. Our most popular sodium sulfite blend is a 19% neutral 7 pH liquid solution or in concentrated powder form. Other liquid blends are also provided. These blends may include:
Sodium Sulfite - Cas. No. 7757-83-7
Potassium Sulfite - Cas. No. 10117-38-1
Diethylhydroxylamine - Cas. No. 3710-84-7
BiSodium Sulfite - Cas. No. 7681-57-4
The liquid version may be added directly to the system. The powder form must be mixed with water prior to injection. Always feed your oxygen scavenger as far back in the system as possible to protect the feed water tank or DA and feed water pumps. Always injection the chemical into the center of the tank with a chemical injection quill with a check valve.
