Directions for use
NALFLEET™ Hardness Treatment 7208 should be fed continuously in order to properly protect the boiler. NALFLEET™ Hardness Treatment 7208 can be fed neat or in any convenient dilution made up in soft water or cooled condensate. NALFLEET™ Hardness Treatment 7208 must not be mixed with oxygen scavengers or condensate system corrosion inhibitors.
Sampling and Testing
NALFLEET™ Hardness Treatment 7208 is normally used in conjunction with NALFLEET™ Alkalinity Control treatment in a conventional alkaline phosphate treatment programme for HP boilers, where independent control of phosphate and alkalinity control is required.
Dosing and Control
The dosage of NALFLEET™ Hardness Treatment 7208 depends on a number of operational factors such as feed-water quality, boiler design and steam rate. Control of NALFLEET™ Hardness Treatment 7208 is by a simple test to give the required level of phosphate (as PO4) in the boiler water. A simple Hardness Treatment test kit is available for this purpose. NOTE: Dependent on water quality, NALFLEET™ Hardness Treatment 7208 dosed at 0.25 liters/ton will increase the phosphate reserve by the order of 10mg/l.
