OxyShield Boiler Oxygen Scavenger should be fed continuously to the deaerator storage section, the condensate or directly to the boiler. Choice of feed point is dependent upon the specific problem to be corrected. The recommended concentration to be maintained in the feedwater will vary with operating pressure and the particular installation and will be advised by Accepta technical support. The normal dosage rate for OxyShield Boiler Oxygen Scavenger is 20ml/m3 of feed water per mg/L of dissolved oxygen and the dosage should be adjusted to give a residual of 0.1 -0.25ppm of DEHA in the feed or boiler water.
