An oxygen scavenger is a material in which one or more reactive compounds can combine with oxygen to reduce or completely remove oxygen in fluids and enclosed packaging.
Dissolved oxygen in the boiler is very corrosive at higher temperatures and pressures The presence of dissolved oxygen in boiler feedwater can present serious problems in a steam generating plant by promoting corrosion in the feedwater system, the boiler, and the steam condensate system. Therefore, it is important to remove oxygen from the feedwater and also from the condensate where inleakage can occur.
