密相段管束布置对料腿内气固流动特性的影响

The Influence of the Arrangements of Pipes on Gas solid Flow Characteristics in the Dense Section of the Stand Pipe

在冷态试验台上研究了循环流化床料腿密相段中不同管束布置方式对气固流动特性的影响。重点研究管束所占料腿截面比例和管子截面形状对循环灰量、松动风调节范围、松动风在料腿密相段中的分配比例以及料腿密相段中的气固流动压降的影响关系。

The influence of the arrangements of pipes on gas solid flow characteristics in the dense section of standpipe in the circulating fluidized bed is studied on a cold state experiment platform.The influence relationships of the percentage of area of pipes in the standpipe cross section and section shape of pipes and the circulation rate,adjusting range and distribution percentage of loose air are studied emphasizedly.
