摘要：Fluidized bed technology is widely used in industry. Industrial processes such as natural uranium conversion, direct reduction ironmaking, and chemical chain combustion use heavy particles with a particle density of more than 4.0 g/cm3. However, in traditional chemical and energy industries, lightweight fluidized bed particles with smaller density are widely used. This article reviews the application background of high-density particle fluidization technology in some industries,which particle densities are beyond 4.0 g/cm3, and explores the impact of high-density particle fluidization quality on system performance. Subsequently, the article reviews the research progress in high-density particle fluidization, highlighting that both experimental measurements and numerical simulations indicate significant differences in the fluidization behavior between high-density and low-density particles. However, existing studies on the fluidization characteristics of high-density particles remain insufficient, particularly regarding the flow characteristics and differences compared to low-density particles. Finally, combined with the needs of related industrial processes, this article focuses on the basic research content of heavy particle fluidization that should be supplemented in the near future. ? 2025 Materials China.
