Abstract
The present blast furnace and method for operating a blast furnace are able to reduce COproduction and the amount of applied additives and heating material. The method for metal production of metal ores comprising the following steps: reducing a metal ore, particularly a metal oxide, and thereby producing furnace gas containing COin a blast furnace shaft; discharging the furnace gas from the blast furnace shaft; directing at least a portion of the furnace gas into a COconverter and reducing the COin the furnace gas into CO; directing at least a portion of the CO from the COconverter into the blast furnace shaft. The method produces CO as a gaseous reduction agent which may be easily introduced into the blast furnace shaft. Further, a blast furnace for metal production by reducing a metal ore designed for operating according to the method is described.
