Lamont Boiler: Definition, Parts, Working, Advantages

Economizer is a device for increasing boiler efficiency. So the work of the economizer is to preheat the water by the use of remaining heat flue gases of the combustion chamber. In the repetition, the feed water is first entered into the economizer before entering into the boiler because it will preheat the water that is the major advantage of it.
