Definitions

  • the present invention relates to a device for delivering powdered solids to and through a central passageway in an oxygen burner, for melting the material subsequent to its exit from the central passageway of said burner, said device including a screw pump whose outfeed end is connected to said central passageway.
  • Figure 3 is a schematic cross-sectional view of a preferred embodiment of the helix profile of the screw pump.
  • a flange 10 which is connected with a bridging piece 11 having flanges 12, 13 mounted on respective ends thereof.
  • the bridging piece 11 preferably has the form of a truncated cone and its base end carries the flange 12, which is connected to the outfeed end of the pump 1.
  • the front flange 13 of the bridging piece is connected to the infeed end of the central passageway 15 of the oxygen burner 16, via a flange 14 at the infeed end of the passageway 15.
  • the oxygen burner 16 is provided with oxygen and fuel connections.
  • Figure 2 illustrates an insert 18 which is intended for insertion into the downstream end of the hollow shaft 3.
  • the insert 18 forms an outfeed opening 19 in the form of a laval nozzle.
  • the hollow shaft 3 may also be manufactured with an outfeed opening in the form of a laval nozzle.
  • the outfeed opening of the insert 18 as well as the outfeed opening of the hollow shaft 3 for gas can be in the form of a Lavel nozzle.

Abstract

Dispositif destiné à acheminer des solides réduits en poudre vers et à travers un passage central (15) dans un brûleur à oxygène (16) en vue de faire fondre le matériau une fois qu'il est sorti du passage central (15) du brûleur (16). Ledit dispositif comprend une pompe à vis (1) dont l'extrémité de sortie est reliée au passage central (15) du brûleur (16). Cette invention se caractérise par le fait que la pompe à vis (1) possède un conduit creux (3) dont l'extrémité d'alimentation peut être reliée à une source de gaz (7) et par le fait que la pompe (1) peut être reliée au passage central (15) du brûleur (16) par l'intermédiaire d'un pont (11).
