| description | A method for operating a smelting furnace installation, in particular a blast furnace installation, the method comprising - feeding coke, iron oxide containing material and if required fluxing agents to the top of the smelting furnace, - injecting a first reducing gas containing hydrogen at a tuyere level of the smelting furnace at a temperature above 1600 DEG C, and - injecting a second reducing gas at a lower shaft level of the smelting furnace, wherein coke is fed at a lump coke rate below 220 kg/t HM, preferably below 200 kg/t HM and more preferably below 180 kg/t HM and wherein the density of the first reducing gas is below 0.80 kg/Nm3, preferably below 0.60 kg/Nm3 and most preferably below 0.30 kg/Nm3. |
