| 摘 要： | 对氧气高炉进行了数值模拟,数值模拟结果表明氧气高炉炉顶煤气循环利用,可以降低燃料消耗5%左右,炉顶煤气CO2进行储存及资源化利用,可以减少CO2排放56%以上。通过分析氧气高炉的工业化试验情况,说明氧气高炉要实现低成本生产,尚需要解决高效喷吹及全流程优化控制技术,循环煤气加热技术,炉顶煤气CO2脱除技术和CO2储存及资源化利用技术四个关键问题,同时为发展氧气高炉炼铁新工艺提出建议。

| Abstract: | A numerical simulation of the oxygen blast furnace is established in this paper.The results show that fuel consumption can be reduced by 5% when top gas of the oxygen blast furnace is recycled and CO2 emissions can be reduced by more than 56% when CO2 in the top gas is stored and utilized.Industrial tests of the oxygen blast furnace indicate that,order to achieve low-cost production,four key problems are to be solved,namely,high injection efficiency,full-process control,recycled gas heating,CO2 removal from the top gas,CO2 storage and utilization.Meanwhile,proposals for development of the oxygen blast furnace iron-making process are put forward. |
