What is the function of economizer in boiler? …

The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler. A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater.

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.
