The article takes two newly built hot blast furnaces in a certain steel enterprise as the re-search object,calculates the influence of oxygen-enriched concentration on parameters such as factual air quantity,flue gas volume,and theoretical combustion temperature during the combustion process of blast furnace gas,and compares it with the effect of blending converter gas.Based on the production data of the newly built hot blast stove,the effectiveness of oxygen-enriched combustion was verified.The results showed that 5.2%oxygen-enriched can increase the hot air temperature by about 59℃.The economy of oxygen-enriched combustion is better than that of equivalent converter gas,and the cost of oxygen-enriched combustion reduced about 14%compared with converter gas.
