  • Boiler 101 | What is a boiler? - Home | American Boiler

    In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3,000 psi, sometimes higher) are required.Get Price

  • ASME Boiler and Pressure Vessel Code - Wikipedia

  • Boiler water treatment - Lenntech

    The treatment and conditioning of boiler feed water must satisfy three main objectives:.

  • 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

  • High Pressure Boiler: What is it? Types & Characteristics

    Characteristics of a High Pressure Boiler Power of Steam: Water expands 1600 times to form steam, which can carry large amounts of heat.

  • Boiler (power generation) - Wikipedia

    A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.Get Price

Blowdown in Boiler, Usually, water which is fed to the boiler contains high Total Dissolved Solids (TDS) content as well as other dissolved and undissolved solids in it. On heating water or converting water to steam, these dissolved solids do not evaporate and gets separated from water or steam and settled at the bottom of the shell.Get Price
