  • Dry pulverized solid material pump
    Patent number: 4462739
    Abstract: Apparatus is shown for substantially increasing the feed rate of pulverized material into a pressurized container. The apparatus includes a rotor that is mounted internal to the pressurized container. The pulverized material is fed into an annular chamber defined by the center of the rotor. A plurality of impellers are mounted within the annular chamber for imparting torque to the pulverized material.
    Type: Grant
    Filed: March 30, 1982
    Date of Patent: July 31, 1984
    Assignee: Lockheed Missiles & Space Co., Inc.
    Inventors: John W. Meyer, John H. Bonin, Arnold D. Daniel, Jr.
  • Coal pump
    Patent number: 4422809
    Abstract: A device for pressurizing pulverized coal and circulating a carrier gas is disclosed. This device has utility in a coal gasification process and eliminates the need for a separate collection hopper and eliminates the separate compressor.
    Type: Grant
    Filed: June 15, 1981
    Date of Patent: December 27, 1983
    Assignee: Lockheed Missiles & Space Co., Inc.

  • Kinetic extruder - a dry pulverized solid material pump
    Patent number: 4376608
    Abstract: Method and apparatus are shown for the continuous feeding of pulverized material to a high pressure container. A rotor is located within the high pressure container. The pulverized material is fed from a feed hopper through a stationary feed pipe to a vented spin-up chamber to a plurality of two-stage sprues mounted in the rotor. Control nozzles downstream from the sprues meter the flow of coal through the sprues.

  • Means and apparatus for throttling a dry pulverized solid material pump
    Patent number: 4362441
    Abstract: Method and apparatus are shown for control of continuous feeding of pulverized material to a high pressure container. A rotor is located within the high pressure container. The pulverized material is fed from a feed hopper through a stationary feed pipe to a vented spin-up zone chamber to a plurality of sprues mounted in the rotor. Control of the pressure within control nozzles downstream from the sprues adjusts the flow rate of coal through the sprues.
