    Economizer - an overview | ScienceDirect Topics

    Economizers for boilers have been available for nearly 150 years, almost as long as boilers themselves. For modern shell boilers, high efficiencies have made it increasingly difficult to justify the use of an economizer, the final decision being based in terms of payback period, which is …

    Boiler Economizers | CBW Industrial Boiler Waste Heat

    Studies have shown that over a 20 year period, 96% of the cost of operating a boiler system comes from fuel costs. Also, in a typical boiler system, 10% to 20% of energy input is lost in the form of heat escaping to the atmosphere. The installation of a boiler economizer helps to solve this problem.

    Chapter 14 - Boiler System Failures | SUEZ

    The most severe damage occurs at the economizer inlet and, when present, at the tube weld seams. Where economizers are installed, effective deaerating heater operation is absolutely essential. The application of a fast-acting oxygen scavenger, such as catalyzed sodium sulfite, also helps protect this vital part of the boiler.
