摘要
文章利用傅里叶红外光谱对9种高炉喷吹煤粉的官能团结构进行了解析。建立了喷吹煤官能团结构参数与烟煤和无烟煤混煤燃烧性能的关系,阐明了混合煤粉燃烧过程中烟煤燃烧行为对无烟煤燃烧的影响,为制定更为合理的高炉喷吹煤混煤制度提供了理论依据。同时,利用火焰回流长度描述了官能团结构对煤样爆炸行为的影响规律,阐述了不同挥发分含量和官能团结构烟煤爆炸的爆炸机理,为制定更为合理的煤粉爆炸性能测试标准提供理论参考。
The functional group structure of nine coal samples applied for blast furnace pulverized coal injection was analyzed with Fourier transform infrared spectrometer and the relationship between functional group structure parameters and combustion property of coal blends was established.Eventually,the influence of bituminite combustion on anthracite combustion was revealed,which provided a theoretical basis for the formation of rational coal blending scheme for pulverized coal injection.Meanwhile,the impact of functional group structure on explosive performance of pulverized coal was clarified by backflow flame length measurement,which deduced the explosion of pulverized coal with different volatile content and provided reference for the rational evaluation in explosibility of pulverized coal.
