  • WtE Boiler Tube Corrosion: On-Site Cladding stops Alkali

    Boiler tubes are cooled with pressurized water or steam and heated up by corrosive combustion flue gases from about 1000°C down to around 250°C. Corrosion occurs at the tube surface which is typically the water temperature plus a gradient through the thickness between 40°C and 20°C. The skin temperature can also change with the building of Learn More

  • US20080163792A1 - Preventing tube failure in boilers

    The erosion-prone sections of the tubes in a circulating fluidized bed boiler are provided with a locally thickened sidewall without forming discontinuities on the outer surface of the tubes. This can be accomplished, for example, by replacing the erosion prone portion of the tube with a section having a smaller inside diameter, but the same outside diameter, or by replacing the erosion prone Learn More

  • Selection Criteria for Steam Boilers - IQS Directory

    Jul 02, 2013 · If a tube replacement cannot be done at a reasonable cost, the entire heat exchanger may have to be replaced instead, which increases the life cycle cost of the boiler. Water Quality – While low-water volume, low-mass boilers may produce steam quickly, the water quality must be exceptional to avoid scaling and sludge build-up. For example a Learn More
