Abstract

A method for manufacturing reduced iron using the same, and more particularly, to a burning apparatus heating a coal briquette to manufacture reduced iron, which includes a first burning furnace heating the coal briquette while moving the truck accommodating the coal briquette along a linear movement path; a second burning furnace connected to the other side of the first burning furnace, and heating the coal briquette while moving the coal briquette discharged from the truck along an annular path; and a cooling device connected to the second burning furnace, and cooling the reduced iron while moving reduced iron reduced in the second burning furnace along an annular path. The burning apparatus circulates exhaust gases generated in the burning furnace and cooling device to control a temperature and an oxygen concentration and thus improves a metallization rate of the reduced iron.
