MEANS AND APPARATUS FOR THROTTLING A DRY PULVERIZED SOLID MATERIAL PUMP

摘要

Method and apparatus are shown for control of continuous feeding of pulverized material to a high pressure container (12) A rotor (10) is located within the high pressure container (12). The pulverized material is fed from a feed hopper (16) through a stationary feed pipe (14) to a vented spin-up zone chamber (30) to a plurality of sprues (32) mounted in the rotor (10). Control of the pressure within control nozzles (34) downstream from the sprues (32) adjusts the flow rate of coal through the sprues (32).
