Zusammenfassung:	An integrated system for blast furnace iron making and power production based upon higher levels of oxygen enrichment in the blast gas is disclosed. The integrated system leads to; 1) enhanced productivity in the blast furnace, 2) more efficient power production, and 3) the potential to more economically capture and sequester carbon dioxide. Oxygen enhances the ability of coal to function as a source of iron reductant and to be gasified within the blast furnace thereby generating an improved fuel-containing top gas. L'invention porte sur un système intégré pour fabriquer du fer de haut fourneau et produire de la puissance sur la base de taux plus élevés d'enrichissement en oxygène dans le gaz de soufflage. Le système intégré conduit à : 1) une productivité accrue dans le haut fourneau, 2) une production de puissance plus efficace, et 3) le potentiel pour capturer et séquestrer de façon plus économique le dioxyde de carbone. L'oxygène augmente l'aptitude du charbon à agir comme source de réducteur pour le fer et à être gazéifié à l'intérieur du haut fourneau, permettant ainsi de générer un gaz de gueulard amélioré contenant du combustible.
