Abstract
A blast furnace process and plant are provided employing a gas mixture comprising coke oven gas and gasified fine grained to dusty fuels. The mixture is produced in a mixing chamber wherein the raw gas from the gasifier is chilled with purified cool coke oven gas. The gas mixture is separated from dust and desulfurized in a cyclone charged with burn lime dust. Then the gas mixture is fed to the blast furnace proper and enters at temperatures from about 750.degree. C. to 1000.degree. C.
