ABSTRACT:
A chain-type fuel feeder which includes a chain conveyor that deposits coal onto a rotor which then throws the coal into a boiler-type furnace. The conveyor is driven from the shaft of the rotor by way of a novel, variable speed control assembly which includes separate, individual, totally integrated, commercially available drive units mounted on the sidewall of the feeder and exposed to ambient air so as to avoid overheating of the drive components and the problems associated therewith. The various drive components are arranged so that they are readily accessible for adjustment, repair, or replacement.
