Common Maintenance Issues for Economizer - Steam Boilers

Tube failure is one of the major problems occurring in the boiler. 30% of tube failures occur in the economizer. Economizer tubes face fireside (external) and waterside (internal) corrosion. The fireside corrosion is a function of flue gas components, tube metal temperature, and the method of firing.

Economizer - an overview | ScienceDirect Topics

Esa Kari Vakkilainen, in Steam Generation from Biomass, 2017. 5.3.3 Economizers. 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.
