An industrial ironmaking reactor—producing 0.1 million metric tons of iron per year (Mtpy), equivalent to 12.66 metric tons/h assuming operation of 24 h/day and 330 days/year—was designed. The reactor will produce iron of Xo = 0.95. The normalized driving force of reducing gas, θ, is set at 0.3 at the gas outlet.
