Waste Heat Recovery | TLV - A Steam Specialist Company

Using a principle similar to economizers, waste heat boilers recover heat generated in furnaces or exothermic chemical reactions at industrial plants. These locations may contain significant energy that should not be wasted up a stack. Instead, this energy can be captured to generate low-to-medium pressure steam in a waste heat boiler (WHB).

Heat Recovery for Large Scale Boilers | The Renewable

There is one type of boiler that may not be suitable for flue gas heat recovery, however. Condensing boilers are highly efficient as they already involve heat recovery (up to 90% efficiency in some cases), whereby the flue gases are used to preheat the cold water before it enters the boiler, thus reducing the work the boiler needs to do.
