Meaning Of Carryover In Steam Boiler

  • BOILER WATER TREATMENT - Sensorex

    Boiler water treatment is done to minimize corrosion, deposition, scale, and carryover in the water–steam circuits. The aim is to maximize the reliability of the steam–water circuit. Boiler water treatment has basically two phases: First, we remove impurities from the water to the desired cleanliness.

  • Boiler Water Antifoam Defoamer | Reducing Carryover Risk

    A boiler' job is to generate steam, impurities within the feedwater which are not boiled off with the steam will remain present in the boiler water and increase in concentration. As concentration of the dissolved solids increases the foam bubbles tend to become more stable and less vulnerable, this helps to increase foaming as the agitation of the boiling water isn't bursting the bubbles.

  • meaning of carryover in steam boiler Agent

    In low/medium pressure boilers (<100 bar) entrained boiler water is the most common cause of steam contamination. Both mechanical factors such as boiler design, high water levels, load characteristics and chemical factors such as high solids concentration, excessive alkalinity, presence of contaminants contribute to the creation of carryover.

  • Foaming and priming in boilers - Lenntech

    Priming is the carryover of varying amounts of droplets of water in the steam (foam and mist), which lowers the energy efficiency of the steam and leads to the deposit of salt crystals on the super heaters and in the turbines. Priming may be caused by improper construction of boiler, excessive ratings, or sudden fluctuations in steam demand.
