  • What is an economizer in a boiler? - Boiler basics - ZOZEN ...

    2021-7-2u2002·u2002What is an economizer in a boiler? In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more ...

  • What does an economizer do in a boiler? - Boiler basics ...

    2021-5-7u2002·u2002Boiler economizer is a device that uses a portion this remained energy of the flue gas to heat up inlet water (feed water) to the boiler. Since the heat energy is given to the water before it gets fed to the boiler, the requirement of fuel for producing steam is optimized. Because of that, we call this device as an economizer.

    2019-11-27u2002·u2002The economizer is a fabricated assembly of finned tubing that captures waste heat extracted from the boiler's stack flue gases; the exhaust that leaves the boiler stack (or 'flue'). It's all about the principle of Heat Transfer. While low temperature water, or feedwater, enters a boiler system, high temperature flue gas exits.
