Economizer recovers the energy by heating the boiler feed water. Economizers scavenge the waste heat from thermal exhaust flue gases by passing the exhaust effluent through heat transfer surfaces to transfer some of the waste heat to a process media. Its Efficiency is in direct relationship to equipment design and stack gas velocities.
