摘要： In a process for producing a reduction gas containing hot CO and H2 for reducing lump ore, particularly iron ore, the reduction gas is formed by gasification of carbon containing materials, particularly coal, under the addition of oxygen in a gasification zone (8) and subsequently cooled to a reduction gas temperature conducive to the reduction process. To produce a reduction gas of greater thermodynamic stability, H2O and/or CO2 are added to eliminate the Boudouard and heterogeneous water gas reaction and the concomitant warming of the reduction gas.

摘要： A method for producing liquid pig iron or steel intermediate products made from lumpy ferriferous material in a melt-down gasifier, whereby coal and gas containing oxygen are added, a reduction gas is formed simultaneously and the ferriferous material is melted. Pieces of coal are introduced into the melt-down gasifier from above, forming a static bed in the melt-down gasifier in conjunction with the ferriferous material, whereby said coal discharges its proportion of volatile hydrocarbons into the domed area above the static bed and the dust burner is inclined from above at an angle to the surface of the static bed. The dust burner is operated and controlled in such a way that combustion of at least 40 % of the proportion of carbon in the fine-particled carbon carriers results in the production of CO2. The invention also relates to a device for carrying out said method. The invention makes it possible to reduce the amount of dust discharged from the melt-down gasifier with the reduction gas and to reduce the tendency of any further discharged dust to agglomerate.
