Abstract: A riffle distributor assembly for influencing the travel properties of a material feed stream 42 moving between a pulverizer 14 and a furnace 12 is part of a feed path 36 having one duct 44A having a branch entry 66A and another branch duct 44C having a branch entry 66C both downstream of upstream passage peripheries UPZ defined between adjacent intake vanes 114 through which the feed stream of the material 42 travels in two segregated portions. A motor drive assembly 58 moves the intake vanes 114 relative to the incoming flow reference axis IFA, whereupon intake areas defined between adjacent intake vanes 114 moves relative to the incoming flow reference axis IFA such that the travel properties of the one portion of material in the one branch duct 44A are different than its travel properties before the movement of intake areas defined between adjacent intake vanes 114.

Abstract: A pivot mounting apparatus 210 is provided for pivotally mounting to one another the coal nozzle tip 212 and coal nozzle body 214 of a pulverized solid fuel nozzle 208 of a pulverized solid fuel-fired furnace 10. The pivot mounting apparatus 210 includes a latch interconnecting assembly 220 that includes a pin 222 for insertion in a traversing movement through an insertion passage 224 which passes through both the through hole 216 of the coal nozzle tip 212 and the through hole 218 of the coal nozzle body 214 upon the mutually facing positioning of respective sides of the coal nozzle tip 212 and the coal nozzle body 214 with one another with their respective through holes 216, 218 both co-axial with an insertion axis IAX.
