An economizer uses the waste heat from the boiler exhaust, that would otherwise be lost to atmosphere to (in most cases) preheat the feed water into the boiler.

This improves the boiler efficiency and reduces fuel costs.

the economizer is a steam generation system as like a boiler. when the exhaust gas discharge from the engine cylinder through the exhaust valve it goes to the boiler for generate steam by heating of water. after those gas it goes through the economizer the remaining exhaust gas temperature is heated the water in economiser. it help to generate steam, and it is improving the efficiency and save the fuel consumption @ save the coast of fuel.
