Explanation by: Mr. Dubey
function of the economizer is to recover a portion of heat of the exhaust gases before the flue gases enter the chimney and discharged to the atmosphere. due to the high temperature of feed water, fuel consumption reduces. this increases the overall efficiency of the boiler.
