Economizer - an overview | ScienceDirect Topi
The economizer has the lowest steel temperature of any heat exchanger surface in the pressure vessel. Therefore it can usually be constructed from carbon steel (Teir, 2004). The economizer is placed as the last of the flue gas to steam–water heat exchanges. The flue gas flow has a low temperature, so fouling is normally not a big problem.

HeatSponge Economizer Tutori
An economizer is a heat exchanger that is used to transfer energy from an air stream into a liquid stream. Most typical economizers use the flue gas exiting the boiler to preheat boiler feedwater being delivered to the boiler. Most natural gas or fuel oil fired boilers will utilize economizers with extended surface finned tubes.
