  • Finding the Root Cause of Boiler Tube Failures -

    Furnace water wall tubes can also fail from long-term overheat. In the case of water wall tubes, the tube temperature increases abnormally, most commonly from waterside problems such as deposits, scale, or restricted flow. In the case of either superheater or water wall tubes, eventual failure is by creep rupture.

  • How Power Plant Boiler Works? -

    Water Walls get the water from the 'downcomers' which are large pipes connected to the drum. The downcomers and the water wall tubes form the two legs of a water column. As the water heats up in the furnace a part of the water in the water-wall tubes becomes steam. This water steam mixture has a lower density than the water in the downcomers.
