Provided is a device for producing partially reduced iron, with which partially reduced iron having a prescribed reduction ratio can be produced efficiently. The present invention is equipped with: CO sensors that detect the carbon monoxide concentration in an exhaust gas; an Osensor that detects the oxygen concentration in an exhaust gas; an exhaust gas circulation device that adjusts the circulating amount of the exhaust gas supplied to a reduction furnace main body, and an air feed device that adjusts the amount of air that being fed; and a control device that controls these devices. The control devices on the basis of the carbon monoxide concentration in the exhaust gas as detected by the CO sensor and the oxygen concentration in the exhaust gas as detected by the Osensor. 1. A device for producing partially reduced iron including: a reduction furnace main body in which pellets formed by mixing and pelletizing a reduction carbon material and an iron oxide-containing raw material are packed on an endless grate to be heated and reduced; exhaust gas circulating means for circulating an exhaust gas discharged from a pellet bed by discharging the exhaust gas from the reduction furnace main body and feeding the exhaust gas to the reduction furnace main body; and air feeding means for feeding air to the reduction furnace main body ,the device being configured to produce a partially reduced iron by combusting a flammable gas and a volatile component together with the exhaust gas and the air to form a combustion zone in the pellet bed, and causing the combustion zone to move sequentially toward an upper side of the pellet bed along with the movement of the endless grate, the flammable gas generated by the reduction, the volatile component generated when the pellets which are heated heat the pellets in an upper layer, characterized in that carbon monoxide concentration detecting means for detecting a carbon monoxide concentration of the exhaust gas discharged from the ...
