  • EC: Lesson 11. Scale and sludge formation in boilers

    (2) Lowering of boiler safety : Due to scale formation, over-heating of boiler is to be done in order to maintain a constant supply of steam. The over-heating of the boiler tube makes the boiler material softer and weaker and this causes distortion of boiler tube and makes the boiler unsafe to bear the pressure of the steam, especially in high-pressure boilers.Get Price

  • Scale Formation In The Boiler - Bright Hub Engineering

    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. Leading to local overheating.Get Price

  • EC: Lesson 11. Scale and sludge formation in boilers

    Well, a scale is a deposit formed over the heat transfer surface when the solubility limits of the constituents of water are exceeded resulting in the precipitation of compounds over the surface. Scales are nothing but salts of Calcium and Magnesium (existing primarily in the form of sulphates or carbonates), which are highly insoluble in water.Get Price

  • What is Scale? - Definition from Corrosionpedia

    (1) By using well softened water, (2) By frequently 'blow-down operation', i.e., drawing off a portion of the concentrated water. Scales are hard deposits, which stick very firmly to the inner surfaces of the boiler. Scales are difficult to remove, even with the help of hammer and chisel. Scales are the main source of troubles.Get Price
