| description | A partially-reduced iron producing apparatus includes: an exhaust gas circulating device (50) which supplies an oxygen-containing gas to raw-material pellets to be heated by a heat of ignition raw-material pellets, the oxygen-containing gas made by circulating part of an exhaust gas discharged from the raw-material pellets by use of the heat of the ignition raw-material pellets heated in a heating furnace (20) and mixing the discharged exhaust gas with air; and a liquid-tar separating device (105) which is provided in the exhaust gas circulating device (50) and which separates a tar component in the exhaust gas from the exhaust gas as a liquid tar. A partially-reduced iron is produced by heating and reducing the whole of the raw-material pellets in a bed height direction thereof through a combustion region for the raw-material pellets and a heating region for the raw-material pellets, the combustion region formed on an upstream side in a travelling direction of an endless grate by supplying the gas having a high oxygen concentration; and the heating region formed downstream of the combustion region in the travelling direction of the endless grate by supplying the gas having a low oxygen concentration. |
