ABSTRACT:
Material to be deposited on the hearth of a shaft furnace serially passes through a pair of temporary storage containers positioned above the furnace. The uppermost storage container is in the form of a bin open to the ambient atmosphere while the lower storage container is provided with valves at either end whereby it may be hermetically sealed and subsequently brought to furnace pressure. The lower storage container is loaded while at ambient pressure, by releasing furnace charge material previously delivered to the upper storage container into the lower container and subsequently by delivering material directly to the lower container from a conveyor system through the lower container. The upper container is refilled with material while the lower container is at furnace pressure and is discharging its contents into the furnace.
