experiments) kiln capacity by oxygen enrichment to 30-35 vol.% in the combustion air has been reported. Oxygen enrichment has not been applied to reduce CO 2 emissions so far. But the use of enriched combustion air may result in fuel savings and thereby avoids CO 2 production. The decision for a dedicated oxygen supply system (on-site/off-site) depends on the specific need

Pores are left behind in the DRI after oxygen has been removed. These pores, if filled with water, for example, can cause the iron to reoxidize with ambient oxygen, generate heat and occasionally ignite a fire. This makes it difficult to transport the product by ship or to store it in the open air over an extended period of time. To resolve this issue, Kobe Steel developed a technology for ...
