【摘要】 铜闪速炉余热锅炉内的盐化反应对烟尘黏结问题有重要影响。为了解和改善余热锅炉内部烟尘颗粒的盐化反应状况，对其在多种送风模式下内部的流动与传热过程进行了数值仿真，构建了一个能够间接反映盐化反应状态的指标——混合均匀度，并根据此指标对送风模式进行了评估与优化。本研究提出的优化送风模式已在现场应用，并取得了良好的优化效果。更多还原

【Abstract】 Dust sulphation reaction has an important influence on dust accretions in Waste Heat Boiler(WHB)of copper flash smelting furnace.In order to perceive and improve the process of dust sulphation in WHB,numerical simulations were conducted for the processes such as flow and heat transfer in the WHB with different air supply modes.An index named Mixing Uniformity(MU)was proposed to reflect indirectly the process state of dust sulphation, and the air supply mode of WHB were evaluated and optimized by using MU.The optimized air supply mode proposed in this study has been applied in practice and achieved good performance.更多还原
