The shaft furnace (Figure 2) is the core of the DR process. Iron ore pellets are charged at the top, descend due to gravity, and encounter an upward counter-flow of gas. The reducing gas (CO and H 2, plus CH 4, CO 2, and H 2 O, at about 950 °C) is injected peripherally at mid-height and exits at the top. In the lower section of the …
