Chanute - Utility Boiler Economizer

These economizers are usually located in the back pass of the boiler and oriented with the tubes running horizontally. (Click on the picture to the right) The boiler feedwater runs through the economizer circuits in the opposite direction of the gas flow (called counterflow).

Bare tubes are typically utilized in order to minimize ash fouling, but some boiler OEM`s design their economizers with finned tubes, either spiral or long finned. Chanute can produce economizer elements with either bare, spiral finned, or long finned tubes, and if you prefer, re-design your unit to one of the other tube-types. Chanute can also fabricate replacement headers for all utility boiler economizers.
