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： In a method for producing liquid pig iron (9) or steel pre-products from fine-particulate iron-containing material (4) in a melter gasifier (1), the iron-containing material (4) is melted in a bed of solid carbon carriers (2) under supply of carbon-containing material (2) and oxygen-containing gas, at the simultaneous formation of a reducing gas, wherein the fine-particulate reduced material (4) and oxygen are introduced into the bed (20, 21) from the side. To be able to charge the fine-particulate iron-containing material to the melter gasifier (1) without a need for briquetting and, in doing so, avoid discharging of the fine-particulate iron-containing material (4) by the reducing gas formed in the melter gasifier (1), a fluidized bed (21) of fine-particulate solid carbon carriers (2) and fine-particulate iron-containing reduced material (4) is maintained above a fixed bed (20) formed of solid carbon carriers (2) and the fine-particulate reduced material (4) is charged into the fluidized bed (21) directly, in immediate contact with oxygen, preferably in the form of a strand having a ring-shaped cross-section and peripherally surrounding an oxygen jet and enclosing the oxygen, such that the oxygen is enclosed by the supplied fine-particulate reduced material (4), and the fine-particulate reduced material (4) is melted in the fluidized bed (FIG. 1).

摘要： In a process for the production of molten pig iron (12) or steel pre-products from fine particulate iron-containing material, in particular reduced sponge iron, in a meltdown gasifying zone (6) of a melter gasifier (5) the iron-containing material is melted in a bed (16) formed of solid carbon carriers, under the supply of carbon-containing material and oxygen-containing gas at the simultaneous formation of a reducing gas. To prevent the fine particles of the iron-containing material charged to the melter gasifier from being discharged, the iron-containing material is supplied into the a melter gasifier (5) centrally, closely above the bed (16) but in its immediate vicinity, by means of an oxygen-burner (15) under the formation of a high-temperature combustion zone (21).

摘要： A process and an arrangement for the production of molten pig iron or steel pre-products from particulate ferrous material as well as for the production of reducing gas in a meltdown gasifier. A fluidized bed of coke particles is formed by the addition of coal and the injection of oxygen-containing gas. In order to ensure a satisfactory mode of operation of the meltdown gasifier even if coal of inferior quality with a high moisture content and a high portion of volatile matter is used, additional heat is supplied to the meltdown gasifier above the feed lines for the fluidized-bed-forming oxygen-containing gas by burning and/or degassing coal particles separated from the reducing gas.
