Method and apparatus for the uniform pneumatic conveyance of finely divided solids and application to the injection of solid fuels into a shaft furnace.

摘要

1. Process for the uniform pneumatic conveyance of finely divided solids which are introduced into propulsion fluid by means of a chamber with a honeycombed rotor, the propulsion fluid being guided through the rotor in a direction parallel to the rotation axis of the latter, characterized by the fact that "down-stream" from the honeycombed-rotor chamber the solid material is separated from the propulsion fluid by centrifugal force in an eddying descending movement imparted to the pneumatic current and returned to it in a progressive and uniform manner, and thereafter carried along with the propulsion fluid.
