ABSTRACT:
A metering feeder for delivering solid fuels, such as municipal or industrial refuse, for combustion includes a pair of generally vertically arranged hoppers. An upper hopper containing relatively compacted or intertangled fuel discharges metered amounts of fuel into a lower hopper through the action of a ram-type pusher. Fuel discharged from the upper hopper is dropped into the lower hopper to develop sufficient kinetic energy to decompact the fuel. An upwardly inclined conveyor removes fuel from the lower hopper at an independently metered rate under optional control of a combustion control system. The action of the inclined conveyor further decompacts the fuel by underraking and mixing, thereby providing a well controlled, uniform, loose density fuel for combustion. The conveyor has a closed course of cleats which cyclically moves to remove fuel. The cleats extend in acute angular relation to the direction of movement for improved performance.
