Zusammenfassung:The invention relates to a shaft furnace, in particular a direct-reduction shaft furnace, with a charge composed of particulate material, in particular a particulate material containing iron oxide and/or sponge iron, the said material being capable of being fed into the shaft furnace from above, and with, arranged in one plane, a multiplicity of gas-inlet orifices for a reduction gas in the region of the lower third of the shaft furnace, the shaft contour having a diametral widening and a cavity being formed between the gas-inlet orifices and the charge. The shaft furnace according to the invention makes it possible to supply gas to the shaft furnace so as to be distributed uniformly over its circumference.
