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.
Claims10
Apparatus for the control continuous feeding of relatively fine particulate material into a high pressure container, comprising:
- a rotor having a central hub and a plurality of sprues providing a passageway through which the particulate material is passed,
- each of said sprues extending radially outward from an inner periphery of said rotor to terminate adjacent to a control nozzle at the periphery of the rotor,
- the sprue at the section adjacent the termination having a low angle of convergence and the nozzle having a substantially greater angle of convergence, and
- variable pressure means connected to said control nozzles at a location radially outward from and adjacent to said sprue for varying the gas pressure within said control nozzles to thereby adjust the flow rate of the particulate material.
