摘要

相干射流氧枪由于其优异的冶金性能，逐渐取代了传统的超音速氧枪。本研究以传统的以天然气为环燃烧气体，以氢气为气体替代的相干射流氧枪为基础，采用数值模拟方法探讨了氢氧相干射流喷射的基本特征和规律。基于流体理论，通过严格的数学推导，得到了氢氧相干射流氧枪的几何参数。对氢气和天然气的混合物作为燃料气体进行了系统的研究，并对结果进行了详细的分析。本研究首次阐明了氢气作为气体在相干射流氧枪中的应用机理，为电弧炉的喷射参数提供了参考，拓展了氢能在炼钢领域的研究方向。

Basic research on the coherent jet with hydrogen as the surrounding gas

ABSTRACT Due to its excellent metallurgical properties, Coherent Jet Oxygen Lance gradually replaces the traditional supersonic oxygen lance. This study is based on the traditional coherent jet oxygen lance that uses natural gas as the ring combustion gas and uses hydrogen as the gas to replace it. Numerical simulation is used to explore the basic characteristics and laws of hydrogen–oxygen coherent jet injection. Based on the fluid theory, the geometric parameters of the hydrogen–oxygen coherent jet oxygen lance are obtained through strict mathematical derivation. A systematic study of the mixture of hydrogen and natural gas as fuel gas was carried out, and the results were analysed in detail. This study is the first to clarify the application mechanism of hydrogen as a gas in the coherent jet oxygen lance, provide a reference for the injection parameters of EAFand expand the research direction of hydrogen energy in the field of steelmaking.
