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

    In high pressure boilers, Na 2 CO 3 decomposes to give sodium hydroxide and carbon dioxide, Na 2 CO 3 + H 2 O → 2NaOH + CO 2. and this makes the boiler water basic ["caustic"]. The NaOH containing water flows into the minute hair-cracks, always present in the inner side of boiler, by capillary action.Get Price

  • Characteristics of boiler feedwater - Lenntech

    A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica, phosphates etc, in relation to working pressure.Get Price
