A minimum water velocity should be maintained at —2 m/s (6 ft/s) for flow equalization. Likewise, the axial velocity in ECON headers should be <6 m/s (20 ft/s). Economizer banks must be restricted to 1.8 m (6 ft) for effective soot blowing. A clear access of 600 mm (2 ft) is necessary for proper access and weld repair. Classification

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.

Boiler Economizer - brighthubengineering.com
Boiler Economizer is usually fitted to increase the efficiency of the boiler by increasing the heat recovery surface so that the maximum amount of heat is recovered from the burnt gases. This is achieved by heating the feed water to the boiler from the burnt gas before it leaves the furnace. In this article we discus the inspection carried out in the economizer and on it gas side of the boiler.
