摘要： The invention relates to a shaft furnace (1), especially a direct reduction shaft furnace, with a charging stock (2) of lumpy material, especially lumpy material containing iron oxide and/or sponge iron, and conveyor screws (3) for removing the lumpy material from the shaft furnace (1). Said conveyor screws intersperse the shaft furnace casing in which they are mounted and are arranged over the floor area of the shaft furnace (1).

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.
