Blast furnace operation with high oxygen and fuel injection rates

When LTV Cleveland's C-5 blast furnace was shut down for a reline, it allowed the operators to divert the natural gas and oxygen injected there to nearby C-6 furnace. The goal of the experiment was to reach 5,000 nthm/day on C-6 using 100 percent natural gas injection and approximately 7.5 percent oxygen enrichment
