Working principle of Economizer - BrainKart

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 powerplants is to capture the waste heat from boiler stack gases ( flue gas ) and transfer it to the boiler feedwater.
