This patent describes an apparatus for feeding a metered flow of solid fuel to a boiler/incinerator operation comprising an upright pair of spaced apart walls constituting respective front and rear hopping defining boundaries, and a pair of belt conveyors each traversing an endless travel course and having upstanding flight members extending crosswise thereon. The upper straight run course of each conveyor travels from bottom to top in the hopper chamber and is operable to transport material from the bottom of a stock of solid waste contained in the chamber. Each conveyor transits a turnaround course at the top of the hopper and discharges the material transported thereby through an associated hopper discharge opening adjacent the turnaround course, and each conveyor has a lower straight run course and a lower turnaround course at the bottom of the hopper. Separate variable speed drive motors connected to each of the conveyors for separating and independently variably controlling the speed of each of the conveyors and correspondingly the rate at which solid waste is transported by a conveyor to its associated hopper discharge opening independently of the rate of which the other conveyor transports waste from the hopper.
