ABSTRACT:
A riffle distributor assembly for influencing the travel properties of a material feed stream42moving between a pulverizer14and a furnace12is part of a feed path36having one duct44A having a branch entry66A and another branch duct44C having a branch entry66C both downstream of upstream passage peripheries UPZ defined between adjacent intake vanes114through which the feed stream of the material42travels in two segregated portions. A motor drive assembly58moves the intake vanes114relative to the incoming flow reference axis IFA, whereupon intake areas defined between adjacent intake vanes114moves relative to the incoming flow reference axis IFA such that the travel properties of the one portion of material in the one branch duct44A are different than its travel properties before the movement of intake areas defined between adjacent intake vanes114.
