Abstract

1520245 Jet pump FHD FURNACES Ltd 30 May 1977 22775/77 Addition to 1384063 Heading F1E [Also in Division F4] Gas flow through a conduit connected to slots in a furnace or other treatment chamber wall is induced by supplying gas under pressure to an annular chamber 16 to flow through a slot 19 between a lip 18 upstream of the chamber 16 and a rounded lip 17 at the upstream end of a Venturi member 15. The jet pump may be connected to the end of the conduit, Fig. 2, or may be mounted within it, Fig. 3, so that the flow induced through the jet pump induces additional flow in the surrounding zones of the conduit.
