Apparatus for controllably introducing particulate material into a reactor by disturbance of the natural angle of repose thereof

摘要

An apparatus for controllably introducing particulate material into the interior of a hollow reactor housing in a predetermined particulate material flow path having a predetermined directional flow for enabling reaction of the particulate material within the housing interior includes means for collecting a pile of particulate material injected into the interior to provide a pile having an unsupported surface oriented to the horizontal at a predetermined natural angle of repose of the particulate. Means are located within the collected pile for introducing a thin stream of fluid into the interior of the collected pile from beneath the pile in the same direction as the predetermined direction of material flow to disturb the natural angle of repose equilibrium condition of the pile for impelling a portion of the collected particulate from the surface into the flow path.
