氧煤燃烧器的研究与开发,对高炉超高量喷吹粉煤(200kg/t以上),最终实现全氧高炉作业具有十分重要的意义。多年来,本文作者在粉煤吹入直吹管后,其燃烧与气化机理;鼓风含氧量与粉煤燃烧率的关系;粉煤喷吹气固两相流特性模拟;氧煤燃烧器结构及其冷、热态实验等方面,进行了广泛研究。所得结果,本文作了详尽地介绍和论述。高炉用氧煤燃烧器的型式可以是多样的,但结构上必须有利于点火,混合、燃烧完全,同时安装方便和运行安全。
Oxygen coal burner research and development of blast furnace super high volume injection of pulverized coal (200kg / t or more), and ultimately achieve full oxygen blast furnace operation is of great significance. Over the years, the author of this paper, after blowing into the straight blowpipe pulverized coal combustion and gasification mechanism; blast oxygen content and pulverized coal combustion rate; pulverized coal injection gas-solid two-phase flow characteristics of simulation; oxygen coal burner Structure and its cold and hot experiments, conducted extensive research. The results obtained, this article made a detailed introduction and discussion. Blast furnace with oxygen coal burner type can be varied, but the structure must be conducive to ignition, mixing, combustion complete, while easy installation and operational safety.
