Replacement of metallurgical coke by pulverized coal (PC) injected in blast furnace (BF) tuyeres is a major economical challenge, due to the high price of coke and unfavorable effect of its production for the environment. But the difficulty consists in necessity of complete gasification of coal particles within raceway and compensating for the negative changes in technology. Theoretical Increase of flame temperature due to increment of oxygen concentration was compensatedby increasing natural gas (NG) and PC consumptions.Productivity in account to equal conditions with rela-36 (1996), No. 10
