    Economizer - an overview | ScienceDirect Topics

    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.
