ABSTRACT

The global warming promotes the steel industry to replace part of coke by injecting hydrogen-rich fuel into the blast furnace to reduce CO2 emissions and energy consumption. In this paper, the injected hydrogen-rich fuels and effects of hydrogen-rich smelting on burden reduction and property evolution were introduced, and the hot events related to hydrogen metallurgy were summarized. Increasing hydrogen content changes the thermodynamic and kinetic conditions of chemical reactions, changing the reduction behaviour of iron oxides and affecting the burden properties evolution and soft melting behaviour. Correspondingly the coke solution loss alters due to more H2O existence. In addition, the temperature and gas flow distribution are altered, affecting the iron oxide reduction rate and efficiency of blast furnace operation process. At present, some hydrogen metallurgy projects have been launched, making expected progress, which provides reference and thinking for the large-scale industrial application of hydrogen in blast furnace.

高炉富氢炼铁技术综述

摘要

全球变暖促使钢铁行业通过向高炉注入富氢燃料来替代部分焦炭,以减少CO 2排放和能源消耗。介绍了富氢燃料的注入和富氢冶炼对减炉料和性能演变的影响,总结了氢冶金相关热点事件。增加氢含量会改变化学反应的热力学和动力学条件,改变氧化铁的还原行为并影响炉料性质的演变和软熔化行为。相应地,由于更多的 H 2焦炭溶液损失改变哦存在。此外,温度和气流分布发生改变,影响高炉操作过程中氧化铁还原率和效率。目前,部分氢冶金项目已启动,取得预期进展,为高炉氢的规模化工业化应用提供参考和思路。
