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.

煤中的矿物质以各种形式和大小存在，导致热行为大不相同。煤中矿物质的热转化影响焦炭的性质及焦炭在高炉中的后续使用性能。早期的研究是基于煤的大量灰分分析。在目前的项目中，计算机控制的扫描电子显微镜将取代在高炉模拟条件下对煤、焦炭和热处理焦炭进行的大量灰分分析，以调查和模拟煤中矿物质对炼焦过程中焦炭结构的影响及其对高炉性能的后续影响。
