Steam Tip 26: Consider Installing a Condensing Economizer ...

A conventional feedwater economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to the boiler feedwater. For natural gas-fired boilers the lowest temperature to which flue gas can be cooled is about 250°F to prevent condensation and possible stack or stack liner corrosion.

Economizers | CleanBoiler.org

Economizers Introduction. 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 operation. Stack should be considered as an efficiency measure when large amounts ...

Boiler Economizer: What is it? (Function & Construction ...

Oct 28 2020 · Boiler 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.

Economizer - an overview | ScienceDirect Topics

Economizers are one of the four main heat transfer surface types. The name economizer comes from German Ekonomizierung (to economize). They were first used in shell and tube boilers to preheat the feedwater. Feedwater preheating helps to capture more heat from the flue gases. Economizers are usually convective heat transfer surfaces.
