Claim Text:
1. An eductor for conveying materials, comprising: a body including a pressure boundary, the body defining a first end and a second end and having a first inlet proximate the first end and a body outlet proximate the second end, the body defining a second inlet positioned between the first inlet and the body outlet, and the body defining a first interior area which extends between the first inlet, the second inlet and the body outlet, the body defining an interior surface; and a plurality of inserts disposed within the body, each insert having an exterior surface, said plurality of inserts being formed of an abrasion resistant material, wherein the plurality of inserts include: a mixing chamber insert positioned in the first interior area proximate the first inlet and extending downstream thereof, the mixing chamber insert defining a second interior area that is in communication with the first inlet, the second inlet and the body outlet wherein the mixing chamber insert includes a first mixing chamber insert inlet arranged proximate the first end of the body, a mixing chamber insert outlet arranged proximate the second end of the body and a second mixing chamber insert inlet; a motive fluid nozzle positioned in the first inlet; a feeder conduit insert positioned in the second inlet, the feeder conduit insert defining a third interior area that is in communication with the second interior area, the feeder conduit insert protruding into the second mixing chamber insert inlet; a venturi outlet insert positioned in the body outlet: and a venturi inlet insert positioned in the first interior area, wherein each exterior surface is complementary in shape to a corresponding portion of the interior surface, both surfaces spaced apart from each other by a distance to allow for radial thermal expansion and contraction of the mixing chamber insert, the feeder conduit insert, the venturi inlet insert and the venturi outlet insert.
