Directions for use

NALFLEET™ Oxygen Scavenger 9-002 is used in feedwater and condensate systems to scavenge oxygen and maintain passive metal surfaces. It reacts with the oxide film on steel surfaces in a boiler system to form a magnetite layer which gives metal protection. This "passivation" technique is useful for pretreatment of new boiler plant and for protection of boilers during idle and storage periods.

Dosing Method
NALFLEET™ Oxygen Scavenger 9-002 must be added continuously by means of a chemical pump at the earliest practicable point in the feed system e.g. the deaerator storage or condenser extraction pump discharge.

Sampling and Testing
NALFLEET™ Oxygen Scavenger 9-002 may be used in all types of boilers operating at pressures up to 2700 psig but is particularly suitable for use at high pressure where oxygen corrosion becomes rapid and where the deposition of metallic corrosion products can quickly lead to overheating and failure of generating tubes.

Dosing and Control
NALFLEET™ Oxygen Scavenger 9-002 can be fed neat or in any convenient dilution. Dilution should be carried out using condensate or de-aerated water. Polyethylene and stainless steel (type 304 & 316) are compatible materials for solution tanks and it is recommended that one or more layers of "Allplas" balls be used to minimise the reaction of NALFLEET™ Oxygen Scavenger 9-002 with air.
