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: The present invention relates to a method for the conveyance of fine-grained solids in a fluidized bed reactor and also to a corresponding plant. It is proposed to introduce a first gas or gas mixture from below through a central tube (3) into a mixing chamber (7) of the reactor (1), the central tube (3) being at least partly surrounded by a stationary annular fluidized bed (10) which is fluidized by supplying fluidizing gas. The gas velocities of the first gas or gas mixture as well as of the fluidizing gas for the annular fluidized bed (10) are adjusted such that the particle Froude numbers in the central tube (3) are between 1 and 100, in the annular fluidizied bed (10) between 0.02 and 2 in the mixing chamber (7) between 0.3 and 30.
