Oxyfuel oxygen-blown (OFOB) refers to a group of advanced combustion technologies that utilize high-purity oxygen instead of air to enhance the efficiency and performance of industrial processes, particularly in metallurgy and energy production. Unlike traditional air-blown systems, which rely on atmospheric nitrogen, OFOB systems eliminate the inert nitrogen component, allowing for more precise control over combustion conditions.

In metallurgy, oxygen-blown processes are commonly applied in steelmaking, particularly in basic oxygen furnaces (BOFs). Here, oxygen is injected directly into molten iron to accelerate the oxidation of impurities such as silicon, manganese, and carbon, resulting in faster and more efficient steel production. The absence of nitrogen reduces energy losses and improves the thermal efficiency of the process.

Beyond steelmaking, OFOB technology is also employed in waste-to-energy plants, where oxygen enrichment enhances combustion temperatures, improving fuel flexibility and reducing emissions. This approach is particularly useful for treating challenging waste streams, such as biomass or refuse-derived fuels, by optimizing heat transfer and minimizing unburned carbon losses.

The primary advantages of oxygen-blown systems include higher thermal efficiency, lower fuel consumption, and reduced environmental impact due to more complete combustion. However, the high cost of oxygen production—typically generated via cryogenic air separation—remains a key consideration. Advances in membrane-based oxygen separation and energy recovery systems are helping to mitigate these costs, making OFOB technologies increasingly viable for large-scale industrial applications.

Overall, oxygen-blown combustion technologies represent a significant evolution in industrial process optimization, offering improved performance and sustainability compared to conventional air-blown methods.
