More Information
Summary:Eductor systems and methods improve eduction by increasing swirl. An eductor housing defines a primary plenum channeling a flow stream from an inlet opening to an exit opening, and defines a secondary plenum separated from the primary plenum and channeling another flow stream from a duct inlet to exit slots. A gas flow stream is delivered into the eductor housing and is directed through the exit opening so that the gas flow stream educes the flow stream through the inlet opening and the exit opening. The second flow stream is delivered to the secondary plenum through a duct connected at an angle to induce a swirl in the secondary plenum to effect a static pressure reduction at the exit opening that draws the flow stream from the inlet opening through the exit opening.
