Sulfite & Catalyzed Sulfite in Steam Boilers | Chardon

There is a catalyzed form of BJ-10 that can be used just like the normal BJ-10. The dosage rates for the catalyzed version and the normal BJ-10 are interchangeable, and can be determined by the normal boiler calculations and maintaining a residual of 30-60 ppm sulfite in the boiler, and 5-10 ppm sulfite in the deaerator, feedwater or surge tank.
