Heat Recovery with Boiler Stack Economizers

In terms of energy performance, an existing boiler system with an added stack economizer becomes, in essence, a condensing boiler (Figure 3). One advantage of the stack economizer/boiler combination over a new condensing boiler is that with the economizer, flue gases condense at more typical return water temperatures of 70° C (160° F ).

2013/1/22 · In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency.
