    For many years, sulfite and hydrazine were the principal materials used to protect boiler systems from oxygen attack. When hydrazine became listed as a suspected carcinogen, a search began for a replacement. During the search it became apparent that strong reducing agents (oxygen scavengers) should do more than react with and remove dissolved

  • Boiler Oxygen Scavengers

    Dissolved oxygen can cause severe pitting (corrosion) in boiler feedwater systems, economizers and boiler internal surfaces. Mechanical deaeration should remove most dissolved oxygen, but chemical oxygen reduction (called scavenging) is required to provide optimum protection. Oxygen scavengers are designed to reduce (scavenger or destroy
