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

摘要

A rotary charging device for a shaft furnace, in particular a blast furnace,is disclosed. The charging device is equipped with a cooling system. Therotary charging device comprises a rotatable support for rotary distributionmeans as well as a stationary housing for the rotatable support. The coolingsystem comprises a rotary cooling circuit fixed in rotation with the rotatablesupport as well as a stationary cooling circuit on the stationary housing. Aheat transfer device is provided which includes a stationary heat transferelement configured to be cooled by a cooling fluid flowing through thestationary cooling circuit and which includes a rotary heat transfer elementconfigured to be heated by a separate cooling fluid circulated in the rotarycooling circuit. These heat transfer elements are arranged in facingrelationship and have there between a heat transfer region for achieving heattransfer by convection and/or radiation through the heat transfer regionwithout mixing of the separate cooling fluids of the rotary and stationarycooling circuits.
