EFFECT OF MAIN BED TOP STRUCTURE ON THE PARTICLES DESCENDING FLOW NEAR THE BED WALL OF CFB[J]. Thermal power generation, 1998, (6): 4-6. DOI: 10.19666/j.rlfd.1998.06.001.
CFB主床的床顶结构对边壁下降流的影响
摘要
在CFB冷态试验台上
深入研究了CFB主床的床顶结构对边壁下降流的影响。对平床顶结构分三种高度进行了试验
研究得出 :CFB主床的床顶结构是影响边壁下降流的重要因素 ;当流化速度和固体物料循环速率一定时
边壁下降流的延伸长度随着床顶高度的增大而增大
Abstract
In cold test set of CFB
the effect of the main bed top structure on the particles descending flow near the bed wall has been studied.The plate top structure has three different heights.The experiment shows the main bed top structure of CFB has a great effect on the particles descending flow near the bed wall.When the fluidized velocity and particles circulating rate are constant
the higher the main bed top structure height is
the longer the extending length of the particles descending flow near the bed wall is. The results have practical meaning in designing and running of CFB Boiler.
