<p>A directional control apparatus for directing hot flue gases received from a combustion zone, either directly to atmosphere through a main stack or through an auxiliary stack, where heat is recovered from the waste hot flue gases and further utilized as energy. While the directional control apparatus for flue gases is especially suitable in recovering waste heat from an incinerator, it may also be utilized for recovering waste heat from any type of combustion equipment, such as a furnace, gas heater, or the like. The direction of the flow of hot flue gases is controlled by aerodynamic valving rather than by mechanical means through either the main stack or the auxiliary stack provided with the heat exchanger of a heat recovery apparatus.</p> |
