A ROTARY CHARGING DEVICE FOR A SHAFT FURNACE EQUIPPED WITH A COOLING SYSTEM,

摘要

pA rotary charging device for a shaft furnace, in particular a blast furnace, is disclosed. The charging device is equipped with a cooling system. The rotary charging device includes a rotatable support for rotary distribution means as well as a stationary housing for the rotatable support. The cooling system includes a rotary cooling circuit fixed in rotation with the rotatable support as well as a stationary cooling circuit on the stationary housing. A heat transfer device is provided which includes a stationary heat transfer element configured to be cooled by a cooling fluid flowing through the stationary cooling circuit and which includes a rotary heat transfer element configured to be heated by a separate cooling fluid circulated in the rotary cooling circuit. These heat transfer elements are arranged in facing relationship and have there between a heat transfer region for achieving heat transfer by convection and/or radiation through the heat transfer region without mixing of the separate cooling fluids of the rotary and stationary cooling circuits./p[US2008290567A1]
