Economizer - an overview | ScienceDirect Topics
Economizers for boilers have been available for nearly 150 years, almost as long as boilers themselves. For modern shell boilers, high efficiencies have made it increasingly difficult to justify the use of an economizer, the final decision being based in terms of payback period, which is also heavily dependent on fuel prices.

Boiler Economizer Types And Efficiency Calculation--ZBG
Boiler economizer calculation A generally accepted “rule of thumb” is that about 5% of boiler input capacity can be recovered with a properly sized economizer. A higher percentage can be recovered with a Flue Gas Condenser, assuming there is enough cold water to condense all of the flue gas that is available.
