      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.

      What is Scale Formation? - Goes Heating System

      Most scale formations in boilers can be traced to the presence of hardness in the make-up water. This hardness reacts in the high temperatures environment within the boiler to form an insoluble scale. This insoluble scale coats the heat transfer surfaces, acting as an insulator to impede heat transfer.

      May 21, 2014 · Scale formation can greatly affect heat transfer performance. One-millimeter-thick scale, for example, can add 7.5% to energy costs, while 1.5 mm adds 15% and 7 mm can increase cost by over 70%. Scale forms in boilers due to the presence of various salts, which come out of the solution and are deposited because of the effects of temperature and
