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.
