Abstract
A material feed apparatus for influencing the travel properties of a feed stream of material moving between a pulverizer and a furnace includes a feed path passing through an upstream passage periphery UPZ. The feed path includes one duct A having a branch entry A and another branch duct C having a branch entry C both downstream of the upstream passage periphery UPZ through which the feed stream of the material travels in two segregated portions. A Y-axis drive assembly and the X-axis drive assembly move the nozzle relative to the reference axis RA, whereupon the upstream passage periphery UPZ moves relative to the reference axis RA such that the travel properties of the one portion of material in the one branch duct A are different than its travel properties before the movement of the upstream passage periphery UPZ.
