Boiler Water Treatment Chemicals, Feed, and Control .
a. Oxygen scavengers are best fed to the storage section of the deaerator or feedwater tank. In most low pressure industrial boiler systems, if oxygen remains in the feedwater and enters the boiler, it is too late to remove all of the oxygen and protect the boiler and condensate from oxygen corrosion.Get a Quote
Feed Water Treatment to Avoid Corrosion - Engineering ToolB
Modern once-through supercritical units operates under an oxidizing treatment without the addition of an oxygen scavenger and in most cases with the addition of oxygen to the feedwater. During operation these units either operate with their deaerator vents closed or equipped with oxygen feeders at the deaerator outlets.Get a Quote
