Abstract
The present invention provides devices and methods for increasing the efficiency and economy of direct iron making processes. In one aspect, the energy contained in off gases produced during a direct iron making process may be utilized in a variety of ways to generate electricity. In another aspect, the off gases may be used to control the pressure in the reaction vessel and increase reaction rates and productivity. In yet another aspect, the sulfur content of the off gases is lowered which reduces the amount of scrubbing required before emission into the atmosphere.
