  • PROCESS DESIGN OF STEAM BOILERS (PROJECT …

    Downcomer - A tube or pipe in a boiler or waterwall circulating system through which fluid flows downward between headers. Draft - Draft is the negative pressure (vacuum) of the flue gas measured at any point in the boiler, expressed in millimeters of water column (kilopascals). Economizer - A series of tubes located in the path of the flue Learn More

    Downcomer. Watertube conducting cooler water down to the mud drum. Bent tube boilers are differentiated both by their type and number of drums. When used in as a steam boiler, the hardness forming salts concentrated in the boiler and formed scale on the inside of the tubingLearn More

  • Steam Boiler: Water Drum of Steam Boiler

    Water drum is a pressure chamber of a drum type located at the lower extremity of a watertube-steam boiler convection bank. The steam drum internals and tube sizes are arranged so that subcooled water travels down the tubes into water drum. From water drum, water is distributed by downcomer to lower drum and then distributed again to the tubes Learn More

  • How a Water Tube Boiler Works | Miura America

    Downcomers are tubes that start from the drum and lead water to furnace walls and boiler banks, see (Fig. 4.12 ). Downcomers can be divided to main downcomers and connecting tubes. It is customary that 2–5 large tubes go straight down from the drum. Often in the end of downcomers is a connecting header.Learn More

  • Why do we use a downcomer tube in an AFBC boiler drum? - Quora

    Answer (1 of 2): Well, Not only in AFBC Boilers in all kind of boilers like CFBC, Travelling gate etc downcomers are used. When water enters into the steam drum it gets separated in the steam drum as water and steam. The steam in the steam rushes to superheater coil where it saturated steam …Learn More

  • Boiler Steam drum internals and function

    May 30, 2018 · In the water tube boiler the upper drum (Boiler steam drum) provides for separation of steam from water. It also provides liquid holdup capacity (typically 10 to 60 seconds) to allow for a dynamic response to load changes without losing liquid in the downcomer and riser tubes. The size of the steam drum is determined by …Learn More

    The steam boiler evaporating tubes are heated by thermal radiation and convection. The evaporating tubes are via a drum, downcomer tubes, circulation pumps, connecting tubes and headers connected into the forced circulation loop. Fig. …Learn More

  • Water Tube Boilers | Spirax Sarco

    Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.Learn More

  • Finding the Root Cause of Boiler Tube Failures

    Apr 06, 2020 · This boiling water ultimately becomes steam that can then be released by the boiler to be used for heating and other purposes. The process from a cold start to full steam typically takes minutes, rather than hours. Water-tube boilers also have a downcomer tube that connects the steam drum to the feedwater drum.Learn More

  • Why are downcomers wider and risers narrower in cross

    steam/water mixture through the tubes (water tube boilers) or over tubes (fire tube boilers) in natural-circulation systems is the difference in density between cooler water in the downcomer circuits and the steam/water mixture in the riser tubes. This flow must be adequate to cool the tubes and prevent overheating.Learn More
