| 摘 要： | 本文采用床层压力脉动测试技术,通过凝聚函数法进行分析,对流化床气泡上升过程的变化规律进行了研究。表明气-固流化床浓相段沿床高可划分为三个区域,即初始气泡生成聚并区,气泡相对稳定区和气泡崩破区。并对操作条件,颗粒物性及床层结构因素,对于划分区域的影响进行了探索

| Abstract: | The coherence function was used for analyzing the pressure fluctuation in a gas-solid fluidized bed.The result shows that the fluidized bed might be divided vertically into three regions:the initial bubble formation and coa- lescence region,the relative stable bubble diameter region and the bubble breakup region.The influence of operating conditions,particle propreties and static bed height on the region dividing was also investigated. |
