AN APPARATUS FOR CONTINUOUSLY AND UNIFORMLY CHARGING CONTROLLED QUANTITIES OF FINE SOLID PARTICLES FROM A PRESSURISED STORAGE CONTAINER TO A PRESSURISED REACTION VESSEL

摘要

SPECIFICATION An apparatus for continuously feeding particulate solid material into a pressurized process apparatus such as a reactor, includes a pressurized storage vessel and a conduit connecting the storage vessel with the process apparatus. controlled extracting mechanism, such as a helical screw conveyor, moves the material out of the storage vessel and through a first portion of the conduit. The material is moved through a second portion of the conduit utilizing a slowly flowing carrier gas. A rapidly flowing propellant gas is provided to move the material through a third portion of the conduit and blow the particulate material into the process apparatus.
