Boiler Oxygen Scavenger XY*5
CHARACTERISTIC
• Controls oxygen corrosion
• Passivates preboiler and boiler surfaces
• Improves boiler reliability
•DESCRIPTION AND USE
Boiler Oxygen Scavenger XY*5 is an oxygen scavenger designed to control corrosion caused by dissolved oxygen in preboiler and boiler systems. The scavenger in XY*5 does not contribute inorganic solids to the treated water. The treated water may be used for steam attemperation and to lay up nondrainable superheaters. XY*5 is formulated to meet or exceed the most demanding product purity requirements. It is the product of choice for nuclear applications and in allvolatile systems where even minor product impurities are a concern.
The scavenger in XY*5 is of low toxicity. This product may not be used in drinking water systems or where steam is used for humidification.

TYPICAL APPLICATIONS
Even with good deaerating heater operation, sufficient dissolved oxygen can remain in the feedwater to damage the boiler system. Oxygen in water produces pitting, which is severe because of its localized nature. Economizers and feedwater preheaters are highly susceptible to oxygen attack. The reaction products of XY*5 with oxygen are water, nitrogen and carbon dioxide. Oxygen scavenging with this product contributes no dissolved solids to the treated water.
TREATMENT AND FEEDING REQUIREMENTS
Feed Point - Feed XY*5 to the condensate hot well, the deaerator storage section or the
feedwater line.
Feedrate –Feed XY*5 continuously based on the feedwater dissolved oxygen concentration and the presence of a suitable residual.
Equipment - Because of the low toxicity (see MSDS) of XY *5 compared to hydrazine, it does not require a system designed to minimize operator exposure.
