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

煤中的矿物以各种形式和大小存在，导致热行为大不相同。煤中矿物的热转化影响着焦炭的性质和焦炭在高炉中的后续性能。早期的调查是基于对煤的总体灰分分析。在目前的项目中，计算机控制扫描电子显微镜将用于代替高炉模拟条件下煤、焦炭和热处理焦炭的散装灰分分析，以研究和模拟煤中矿物对炼焦过程中焦炭结构的影响及其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.
