Abstract
A heat recovery system for a boiler has a tank separator connectable to a boiler and receiving a liquid from the boiler as well as separating the liquid into a blow down liquid and a flush vapor, a heat exchanger having an upstream portion and a downstream portion and receiving a make up water to be heated, the tank separator being connected with the upstream portion of the heat exchanger so as to apply hot blow down water into the upstream portion of the heat exchanger therefore to heat the make up water in the upstream portion of the heat exchanger by heat given out by the blow down water, the heat exchanger further having a downstream portion connected with the upstream portion so that the make up water heated by the heat given out by the blow down water further flows into the downstream portion of the heat exchanger, the tank separator being connected with the downstream portion of the heat exchanger so as to supply the flush steam into the downstream portion of the heat exchanger and further heat the make up water in the downstream portion of the heat exchanger by heat given out by the flush steam in the downstream portion of the heat exchanger.
