| description | The invention relates to a prereduction furnace of a smelting reduction facility of iron ore consisting of a fluidizing prereduction chamber (15) installed at the upper part of the prereduction furnace (2) in which iron ores are fed and prereduced, a gas blowing chamber (14) installed at the lower part of the prereduction furnace (2) into which a reducing gas is fed, a ceramic main body (30) of a distributor (12) installed between the fluidizing prereduction chamber (15) and the gas blowing chamber (14), a metal box (31) attached to the bottom side of the main body (30), in which a cooling fluid flows, which prevents adhesion of dust in the reducing gas, nozzles (13) passing through the main body (30) and the metal box (31) for injecting the reducing gas in the blowing chamber (14) into the prereduction chamber (15) and a discharge pipe (19) for discharging prereduced iron ores installed at a bottom center of the prereduction chamber (15) extending through the ceramic main body (30), the metal box (31), and a bottom of the gas blowing chamber (14). |
