Economizer – Wikipedia

  • Economizers, or economisers, are mechanical devices intended to reduce energy consumption, or to perform useful function such as preheating a fluid. The term economizer is used for other purposes as well. Boiler, power plant, heating, refrigeration, ventilating, and air conditioning uses are discussed in this article. In simple terms, an economizer is a heat exchanger.

    Economizers | – Boiler Consortium

    • Flue gases from large boilers are typically 450 – 650°F. Stack Economizers recover some of this heat for pre-heating water. The water is most often used for boiler make-up water or some other need that coincides with boiler operation. Stack Economizers should be considered as an efficiency measure when large amounts of make-up water are used (ie: not all condensate is returned to the boiler or large amounts of live steam are used in the process so there is no condensate to return) or there is…

          Boiler Economizers | Superior Boiler

          Superior Boiler’s economizer was developed to recover this wasted energy while being easy to install and maintain. Your payback depends on your fuel costs, average loading, and hours of operation. We provide an automated program to allow you to see the type of savings your application will realize.


          B&W’s economizer designs are proven to provide effective performance for optimal thermal efficiency. We consider a wide range of factors based on current or expected operating conditions such as low load operation and on/off cycling.

          Boiler Cycling Considerations

          Economizer thermal shock On boilers that are on/off cycled, economizers often show more cyclic damage than other components. The economizer receives water from the extraction feedwater heater system, and the inner metal surface temperature follows the feedwater temperature with practically no time delay.
