associated top turnaround course they pass adjacent hopper discharge openings 28 which will be discussed further later on in the description the conveyors which are effectively disposed at an angle a of substantially 60 u00b0 to a horizontal datum plane are each provided with laterally or crosswise disposed flight members 30 the flight members being e g slat like components functioning to transport fuel material in front thereof along a transported course out of the hopper the flight members 30 may be oriented substantially perpendicular to the face of the conveyor belt on which they are mounted as with conveyor 18l or they may be forwardly inclined in the direction of conveyor travel as with conveyor 18r if forwardly inclined the angulation may be at about one half the angle at which the conveyor is inclined in operation the conveyors 18l 18r follow the travel courses indicated from the lower turnaround courses the conveyors in transiting to an upper straight run scoop up fuel at the bottom of the hopper and the flights transport this fuel as boiler feed up to the top of the hopper as each conveyor 18l 18r is in its top turnaround course travel it passes its associated discharge opening 28 and the fuel gravity feeds off the conveyor and falls onto a chute conveyor 36 by means of which the fuel is carried directly.
