  • CHAPTER 39 BOILER WATER TREATMENT - ssu.ac.ir

    2015-5-26 · water chemistry is essential to the power engineer who continually strives to increase the efficiency of the boilers and steam-using equipment. The pressure and design of a boiler determine the quality of water it requires for steam generation. Municipal or plant water of good quality for domestic use is seldom good enough for boiler feed water.

    Hardness. Water is referred to as being either 'hard' or 'soft'. Hard water contains scale-forming impurities while soft water contains little or none. The difference can easily be recognised by the effect of water on soap. Much more soap is required to make a lather with hard water than with soft water.

  • Water Maintenance Essential to Prevent Boiler Scaling

    The recommendation to install a water meter in the boiler's make-up water system is a good one, even for a boiler not experiencing leakage and scaling. Constant monitoring of water usage may detect otherwise unnoticeable leaking early, so corrective action may be undertaken before any damage occurs.

    2019-8-12 · Because of these conditions, high-pressure boilers are prone to caustic attack. Low-pressure boilers that use demineralized water and condensate as feedwater are also susceptible to caustic attack. There are several means by which boiler water can become highly concentrated. One of the most common is iron oxide deposition on radiant wall tubes.

  • 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.
