摘要： The invention relates to a method for treating, preferably for reducing, particulate material in at least one fluidization zone at an increased temperature, particularly for reducing ore dust. According to the method, the particulate material is held in the fluidization zone by a treatment gas that flows upward from the bottom, and fine-particulate material, which is transported out of the fluidization zone with the treatment gas is separated from the treatment gas in a separating zone. To this end, the following steps are carried out in the separating zone: feeding the stream, which consists of treatment gas and of transported fine-particulate material, to a separating device (8); separating the fine-particulate material from the treatment gas, whereby the treatment gas is extracted from the separating device as waste gas, and; withdrawing the separated fine-particulate material out of the separating device (8). The invention also relates to a device for carrying out the method. Coarse grained material is introduced into the separating zone whereby reducing the amount of baked on material and deposits thereof.

摘要： A method for decreasing the elutriation loss of fine iron ore in a circulati ng fluidized bed type reducing operation is disclosed. The method includes charging lime stone (CaCO3) or dolomite (CaCO3, MgCO3) in an amount of 3-6 vol% together with the fine iron ore into a fluidized bed type furnace. In another embodiment, the method includes the addition of a sludge in an amount of 0.2-5.0 wt% to the fine iron ore and mixing them thus coating the fine iron ore particles; drying the coated particles at a temperature of 105-800.degree.C for 1-24 hours and then charging the coated fine iron ore into a fluidized bed type furnace.

摘要： A process and apparatus for reducing material in particle form in a fluidization zone and at elevated temperature, in particular for reducing fine ore, the particle material being held in the fluidization zone by a treatment gas which flows upward from below. Material in fine particle form is discharged from the fluidization zone with the treatment gas and is separated out of the treatment gas in a deposition zone. In the deposition zone, the stream of treatment gas and discharged material in fine particle form are fed into a separating device which removes the fine particle material from the treatment gas, the treatment gas is extracted from the separating device as off-gas, and the separated fine particle material is removed from the separating device. Coarse-grained material is then introduced into the deposition zone. This reduces the levels of caking and deposits of the fine particle material. A device for carrying out the process includes elements defining the zones.

摘要： A melter gasifier (10) for the production of a metal melt and of a reducing gas is provided with feed ducts (17, 16, 9) for oxygen-containing gases, carbon carriers and the metal carriers. From the melter gasifier (10) there departs at least one gas discharge duct (12) for reducing gas generated in the melter gasifier (10). Also, a tap (18) for the metal melt and for slag is provided. To be able to process fine-particulate metal carriers without the need of briquetting and without entrainment of the supplied fine-particulate metal carriers out of the melter gasifier (10) by the reducing gas generated therein, at least one feed duct (9) feeding the metal carriers is arranged in the region of a dome (30) terminating the melter gasifier (10) toward the top, and in the interior of the melter gasifier (10) below the entry site of the feed duct (9) for the metal carriers a refractory slanting wall (33) inclined towards the vertical line, on which there impinge the metal carriers sinking downward due to gravitational forces. Further, above the slanting wall (33) a heating means (38) is provided by which the area between the entry site of the feed duct (9) for the metal carriers and the slanting wall (33) may be heated.

摘要： A melting gasifier (10) for producing molten metal and reduction gas has feed ducts (17, 17, 9) for oxygen-containing gas, carbon-containing materials and the metal-containing material. At least one discharge duct (12) for the reduction gas generated in the melting gasifier (10) starts from the melting gasifier (10). A tap hole (18) for the molten metal and slag is also provided. In order to allow finely divided metal-containing materials to be processed without briquetting and without the finely divided metal-containing material being entrained out of the melting gazifier (10) by the reduction gas generated therein, at least one feed duct (9) for the metal-containing material is arranged in the area of a dome (30) that encloses the top of the melting gazifier (10). A refractory wall (33) inclined relative to the vertical is arranged inside the melting gazifier (10) below the opening of the feed duct (9) for the metal-containing material. The metal-containing material falling inside the melting gazifier (10) under the effect of gravity hits the inclined wall (33). A heating device (38) is further provided above the inclined wall (33) for heating the area between the opening of the feed duct (9) for the metal-containing material and the inclined wall (33).
