    levels). However, sulfite is not considered to be a good passivating agent because it does not passivate low pressure boilers, where sulfite is most often used. Passivation can be accomplished in high pressure boilers, but high dosages of sulfite are needed. Sulfite is commonly supplied as sodium sulfite, Na 2SO 3; sodium bisulfite, NaHSOLearn More

    pH Control in Boiler Condensate Water Treatment | Murphy Learn More


    The safe pH range for steam boilers is between 8.5pH & 12.7pH, whilst the recommended level is between 10.5pH & 12.0pH. Boiler water with a pH of 10.5 contributes 12.6mg/l towards the boiler TDS, whilst at a pH of 12.0 it increases to 400mg/l and at 12.5pH the value is 1264.9 mg/l a 100 fold increase.Learn More

  • Chemical Treatment Requirements for Steam and Hot Water

    Jun 12, 2017 · Boilers, in one form or another, have been used for centuries to produce steam for heat and power. Today, boilers produce steam to drive electric turbines, heat buildings, and provide power for countless industrial and commercial applications. Although the steam uses may vary, the importance of maintaining the water quality in these systems remains the…Learn More

  • Scaling in boilers - Lenntech

    Causes, and prevention of scaling in boilers, type of scaling. Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots.Learn More

  • Corrosion Prevention in Steam Boiler Systems

    Apr 25, 2016 · In the steam boiler system, the primary routes for corrosion are due to the presence of oxygen in the feed, boiler and condensate waters and the risk of acidic type corrosion due to reduced pH in the condensate water. These types of corrosion are localised and aggressive and can quickly degrade metal pipework and lead to failure.Learn More
