The purpose of the presented paper is to investigate oxygen enrichment in hot stoves for an integrated steel plant. The application of oxygen enrichment in hot stoves will lead to lower coke or PCI rate by increased blast temperature. With oxygen enrichment; the high calorific value COG; could be saved while keeping the same blast temperature. Several alternatives of using the saved COG are presented. Furthermore; an analysis of how oxygen enrichment into hot stoves will have influence on the whole energy system has been carried out by means of an optimization model. Different strategies have been suggested to minimize the total energy consumption at the studied steel plant and the nearby CHP plant.
