| 摘 要： | 风口回旋区的传热传质过程与其内表面积密切相关.以COREX熔化气化炉物理模拟为基础,运用欧氏理论和分形理论确定了不同条件下回旋区的内表面积.结果表明:运用分形理论计算的回旋区内表面积较欧氏理论计算的回旋区内表面积大;随着气量增大,回旋区内表面积增大;随床层高度增大,回旋区内表面积减小;随排料速度增大,回旋区内表面积增大.

| Abstract: | The surface area of raceway has great influence on the heat and mass transfer in raceway.Based on the physical simulation of COREX melter-gasifier,the Euclidean and the fractal theory are applied to determine the surface area of raceway.The results show that the surface area determined by fractal method is greater than that by Euclidean method.The surface area of raceway increases with the increasing of blast volume and discharging rate,while it decreases with the increasing of bed packing height. |
