  • DESIGN OF LOW PRESSURE ECONOMIZER IN FOSSIL

    2021-7-6 · Tube failure is one of the major problems occurring in the boiler. 30% of tube failures occur in the economizer. Economizer tubes face fireside (external) and waterside (internal) corrosion. The fireside corrosion is a function of flue gas components, tube metal temperature, and the method of firing.

  • What Causes Steam Boiler Failure? - Clarity Water

    2. Dissolved Oxygen (O2) Pitting Corrosion is the leading cause of premature failure of a steam boiler. In water, O2 is inversely soluble to the heat applied to it. This means that as a boiler is heated, any and all O2 is released within the confines of the boiler itself. As this O2 is released, it causes extreme and deleterious pitting ...

  • Boiler Economizers | CBW Industrial Boiler Waste

    The installation of a boiler economizer helps to solve this problem. An economizer is a unit that captures heat from the stack, and then returns it to a water system. To determine if a boiler economizer is right for your facility, look at your annual boiler fuel bill and subtract 5 to 10% of the cost.

    2021-8-4 · Steam blanketing is a condition that occurs when a steam layer forms between the boiler water and the tube wall. Under this condition, insufficient water reaches the tube surface for efficient heat transfer. The water that does reach the overheated boiler wall is rapidly vaporized, leaving behind a concentrated caustic solution, which is corrosive.
