Abstract

A rotary charging device for a shaft furnace comprises a stationary housing (112) for mounting on the throat of the shaft furnace; and a suspension rotor (114) with a charge distributor, said suspension rotor being supported in the stationary housing so that it can rotate about a substantially vertical axis. The suspension rotor (114) and the stationary housing (112) cooperate to form the main casing (122) of the rotary charging device, an annular gap (160) remaining between the stationary housing and suspensions rotor. Sealing means are arranged in the vicinity of the annular gap (160) to provide a seal against shaft furnace gas.The sealing means comprise a water seal device (162) with an annular water container (164) and a cooperating annular wall (166). Alternatively, the sealing means comprise one or more nozzles (44) arranged circumferentially in the annular gap (34) to blow clean gas therein.
