以130t／hCFB锅炉炉膛为参考，对其扩口角设计进行优化．采用0．618法对参数进行挑选，利用大型流体计算软件FLUENT进行数值模拟研究．结果表明：通过对扩口角的设计可以改进炉膛内的流动特性，得出扩口角在67°-68°之间有较好的流动特性．

In this paper, the structure of 130 t/h CFB boiler furnace is optimized as a reference. The parameters were selected in the way of 0.618 methods ,The research of structure optimization Numerical Simulation was carried out by the use of large-scale numerical flow calculation software FLUENT simulation. The results showed that adjusting the design of the furnace mouth expansion can improve the flow characteristics. It obtained a good flow characte...
