Boiler stack temperature efficiency

WebThe boiler must also have a forced-draft burner and must not be the high-efficiency condensing type. Energy Information. The real energy savings from a boiler stack economizer come from the drop in temperature of the flue gases flowing through the economizer, multiplied by the mass flow rate of the flue gases.
