【Q&A】What is the effect of blast furnace oxygen enrichment on its smelting process?

After injecting rich oxygen into the blast furnace, the oxygen concentration in contact with the pulverized coal is increased, which is beneficial to the combustion of the powdered coal, to the hearth temperature raising, and to the coal injection ratio increasing. Its major influence on the smelting process is： 1) Improving the Smelting Intensity 2) Conducive to the Smooth Running 3) Reducing the Coke Ratio 4) Improving the BFG Heat Value 5) Beneficial to Smelting of Iron Species Requiring High Energy Consumption After decades of development, VPSA oxygen production technology has grown pretty mature. Under the premise that the oxygen capacity is ≤20000Nm3/h, the VPSA oxygen plant has outstanding advantages over the cryogenic air separator including less investment, less time to start up and shut down and less operation & maintenance costs. For small and medium blast furnaces in the iron and steel enterprises that are in urgent need of technological transformation, PKU Pioneer VPSA oxygen unit, with economical setting-up cost, simple technical process, easy operation, less high-tech personnel needed, and great flexibility and high safety, is an ideal solution for blast furnace oxygen-enriched coal injection.
