The Economizer: What, Why, and How? - Nationwide Boiler Inc.
Apr 14, 2017 · The process is simple. As the flue gas exits the boiler, it enters an economizer with finned tubes. The finned tubes absorb the heat and raises the temperature of the boiler feed water, lowering the needed energy input. Why Add an Economizer? Adding an economizer will increase boiler efficiency by 10-12%.
