Abstract
A new and improved system for feeding solid particulate material such as refuse derived fuel for burning in a combustion reactor vessel such as a boiler includes a fuel injector chute having a lower end for directing a flow of said solid particulate material into the vessel and an upper end for receiving a flow of said material. A feeder is provided having a discharge end for delivering a continuous controllable flow of said material to the inlet of the injector chute and a plurality of separate, spaced apart, vibratory feed hoppers are mounted above the feeder to supply the feeder with a steady flow of material from one or both hoppers. Each hopper is adapted for holding a reservoir or supply of said solid particulate material and is selectively controllable to provide a steady flow of solid particulate material into the feeder for delivery through the injector chute to the combustion reactor vessel.
