| 摘 要： | 数值计算表明,逆向多环形分布射流可造成颗粒能直接进入,并能进行强烈的动量、能量交換的理想的迴流区结构。多环形结构可在大范围內造成所需尺寸的迴流区。逆向射流和主流速度比、环直径、射流直径和孔数、环的结构形式及离燃烧室进口的距离是影响迴流特性的主要参数。

| Abstract: | Results of calculation shown: recirculation zone formed by opposing multi-annular distributing-jets is very suitable for pulverised coal and coal water slurry combustion. The recirculation zone required to establish in large range could be formed by the opposing multi-annular distributing-jets. The main parameters effecting the characteristic of recirculation zone are the ratio of opposing jet velocity to primary stream velocity, the annulus diameter and configuration, diameter and number of jets as well as distance between annulus and com-bustor inlet. |
