A Fundamental Investigation of the Thermoplastic Behaviour and Porous Structural Evolution of Coke and Char Particles

焦炭颗粒热塑性行为及多孔结构演化的基本研究。在加热过程中，固体燃料颗粒经历复杂的物理变化，导致残余材料（焦炭和焦炭）的复杂结构，影响这些材料在炼铁和发电过程中的操作性能。对物理结构演化和气体演化耦合作用的机理认识尚未很好地确立。将通过实验观察和数学模型建立描述这一过程的解释和预测机制。该项目将为有关煤基工业过程中固体燃料残留物的复杂行为的操作问题提供基本的新见解和理解。

A Fundamental Investigation of the Thermoplastic Behaviour and Porous Structural Evolution of Coke and Char Particles. During heating, solid fuel particles undergo complex physical changes resulting in sophisticated structures in the residual material (coke and char) which influence the operational performance of these materials in ironmaking and power generation processes. The mechanistic understanding of the evolution of physical structure and the coupled role of gas evolution has not been well established. An interpretive and predictive mechanism to describe the process will be developed through experimental observations and mathematical modelling. The project will provide fundamental new insights and understanding of operational issues concerning the complex behaviour of solid fuel residues in coal based industrial processes.
