Abstract

The present invention relates to a device and a method for manufacturing a high efficiency reduced iron using syngas, and more particularly, provides a device for manufacturing a reduced iron using syngas and a method for manufacturing the reduced iron using same, comprising: at least one fluidized reduction furnace for reacting fine iron ore with a reducing gas to reduce same into the reduced iron; a fine iron ore insertion means, which is connected to the at least one fluidized reduction furnace, for inserting the fine iron ore; a flue gas discharging means for discharging flue gas which is generated in the at least one fluidized reduction furnace; a syngas supplying means for supplying the syngas, which is used as the reducing gas, into the lower portion of a first fluidized reduction furnace; and an agglomerating means for agglomerating the reduced iron which is reduced from the first fluidized reduction furnace.
