Abstract
Apparatus for charging a shaft furnace for burning carbonaceous mineral material in at least two furnace shafts comprises a common feed container, which is connected to each furnace shaft by a separate charging duct. In order to provide a simple structure and to reduce the overall height, the feed container is designed to constitute a lock chamber, which is provided with a shut-off valve for controlling the inlet port of the feed container and with a plurality of shut-off valves for controlling respective outlet ports connected to the charging ducts.
