APPARATUS AND METHOD FOR THE SUPPLY OF FUEL POWDER TO A GAS-PRESSURIZED VESSEL

摘要

Centrifugal pump for supplying powder to a pressurized vessel. The pump comprises a rotor arranged rotatably in the vessel to inject powder into the vessel by centrifugal force and a supply tube for the supply of powder from outside the vessel to the rotor, the axis of rotation of the rotor coinciding with the centre line of the supply tube. The rotor consists of two trays positioned at right angles to the supply tube. Between the trays there is a slit which forms the connection between the vessel and the supply tube. Preferably the rotor drive mechanism is designed to rotate the trays with a small mutual difference in speed.
