    Abstract: A process for the production and/or treatment of at least one metal in a reactor includes discharging a waste gas stream via a waste gas conduit and after-treating the waste gas stream by supplying a cooling gas and/or a cooling gas mixture. The after-treating includes injecting the cooling gas and/or cooling gas mixture into the waste gas conduit on a side of the waste gas conduit facing the reactor, at a high velocity and substantially tangentially with respect to a main flow direction of the waste gas. A volume of the cooling gas and/or the cooling gas mixture injected into the waste gas conduit is adjusted so as to reduce a mixing temperature below a melting temperature of the molten particles and/or a condensation temperature of the vaporous constituents of the waste gas stream.

    Abstract: PCT No. PCT/EP96/05446 Sec. 371 Date Dec. 21, 1998 Sec. 102(e) Date Dec. 21, 1998 PCT Filed Dec. 5, 1996 PCT Pub. No. WO97/21840 PCT Pub. Date Jun. 19, 1997The granular sponge iron is supplied to a roller press at temperatures of 600 to 850 DEG C. for molding the hot briquets. There is produced a strip structure of sponge iron containing formed hot briquets, which are arranged at a distance from each other. By smashing the strip structure, the hot briquets are separated from each other, so that fragments of the strip structure are obtained. The hot briquets and at least part of the fragments are cooled to temperatures in the range from 20 to 400 DEG C., and the cooled briquets and fragments are passed through a rotary drum. In the rotary drum, fine-grained fines of the briquets and fragments are produced. Subsequently, these fines are separated from the briquets and fragments, as they exhibit a pyrophoric behavior.

    Abstract: A plant for the heat treatment of solids containing iron oxide includes a fluidized bed reactor. The reactor includes at least one gas supply tube at least partly surrounded by an annular chamber in which a stationary annular fluidized bed is located, and a mixing chamber being located above the upper orifice region of the at least one gas supply tube. The gas flowing through the at least one gas supply tube entrains solids from the stationary annular fluidized bed-into the mixing chamber when passing through the upper orifice region of the at least one gas supply tube.
