  • UP Boiler mix stud plate cracking - Case study

    Purpose Advise customers to inspect for cracks in wall tubes in the furnace enclosure mix areas of UP boilers that were designed prior to 1973. Several recent inspections have revealed stud plate deterioration and cracking, which has propagated into the tube wall, typically at the termination of the stud plate or membrane weld. Problem Figure 1 shows the "H" ...

  • Power Plant Improves Operating Efficiency with Culligan Matrix Solutions

    Challenge A large chemical manufacture was challenged with boiler tube failures in its power plant, resulting in costly repairs and down time. The boiler tube failures were a result of the incoming water quality to the power plant. Until recently, the boiler make-up water was treated with a combination of carbon media filtration and softening. As a result less than 50% of condensate was ...

  • Controlling Scale Deposition and Industrial Fouling

    It costs US industry billions of dollars a year to control and remove the limescale that builds up in industrial equipment such a heat exchangers, evaporative coolers, boilers, chillers and other water fed equipment. Oil wells, for example, face significant scaling problems from the highly mineralized water that are extracted with the oil. Limescale not only increases downtime, maintenance ...

  • Application notes: The Sievers InnovOx TOC analyzer: boiler water monitoring

    Background A boiler system is a semi-closed loop system in which water is heated and converted into steam to power a generator. The steam is then allowed to form a condensate and the process is repeated. Boiler water chemistry directly impacts boiler efficiency and fuel use. Improper water treatment allows scale formation and corrosion. Boiler scale and deposits form when impurities ...
