Abstract
Apparatus for monitoring and analyzing a stream of powdered coal has an upright cylindrical vessel whose upper end receives the end portion of a conduit serving to deliver a stream of comminuted material in a gaseous carrier medium. The end portion of the conduit is coaxial with the vessel and is surrounded by a single annular nozzle or by an annulus of discrete nozzles serving to discharge first currents of compressed air into the vessel at a level above the discharge end of the conduit. The descending stream of comminuted material is traversed by several radial currents of compressed air close to the open lower end of the vessel and the thus treated stream of comminuted solid material descends into a second vessel wherein it is traversed and analyzed by a laser beam or a light beam.
