ABSTRACT:
An annular passage arrangement for a pulverizer includes vertically extending inner and outer passage walls which define a "boxed" annular passage. The annular passage space has an inlet for receiving flow from an air plenum and an outlet for vertically channeling the flow into a pulverizing zone. The annular passage is divided by vanes having a tapered end at the inlet end of the passage and an outlet end located at the passage outlet. The outlet end of each vane extends at an acute angle to the horizontal and the tapered end of each vane is vertically oriented within the annular passage. This vane orientation reduces pressure drop as the plenum air is fanned up into the pulverizing zone. Flow contouring plates below the passage inlet reduce flow disturbances and create a more uniform flow pattern up and into the passage inlet.
