A Fundamental Investigation into the Behaviour of Mineral Matter in Coal during Coke Formation and in Blast Furnace

煤中的矿物以不同的形式和大小存在，导致了非常不同的热行为。煤中矿物的热转变影响焦炭的性质和焦炭在高炉中的后续性能。早些时候的调查是基于对煤炭的散装灰分分析。在本项目中，将利用计算机控制的扫描电子显微镜代替高炉模拟条件下的煤、焦炭和热处理焦炭的灰分分析，来研究和模拟煤中矿物在炼焦过程中对焦炭结构的影响以及随后对高炉性能的影响。

Minerals in coal are present in various forms and sizes resulting in vastly different thermal behaviour. Thermal transformation of minerals in coal influences the coke properties and subsequent performance of coke in blast furnace. Earlier investigations have been based on bulk ash analysis of coals. In the current project, Computer Controlled Scanning Electron Microscopy will be used in place of bulk ash analysis for coal, coke and thermally treated coke in blast furnace simulated conditions to investigate and model the effects of minerals in coal on coke structure during coke-making and its subsequent effect on its performance in blast furnace.
