摘要： 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.

摘要： The granular sponge iron is supplied to a roller press at temperatures of 600 to 850.degree. 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.degree. 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.

摘要： 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.

摘要： A method and apparatus are provided for aiding diagnosis of an object showing a disorder and for selecting a finding characterising the state of the object. Each finding is described as a visual pathology by a severity, a symptom constellation of multiple symptoms and by a graphic representation of the symptom constellation. A dialog-based, visual modelling of the state of the object is provided wherein the state of the object is modelled by a current symptom constellation represented by a symbol. The resulting, current object image is immediately graphically output on the display device. Following each case of modification a comparator immediately compares the current symptom constellation against the symptom constellations of stored findings and updates the list of findings of potentially applicable findings. A list of suggestions for examining further symptoms is output, sorted by their differentiation so as to interactively facilitate diagnosis.
