摘　　要：利用大型循环流化床锅炉二维冷态试验台,进行模拟实际给煤颗粒在炉膛内的扩散和掺混试验,根据实验自身可变参数床料粒径、示踪粒子粒径、表观风速和静止床高,确定了炉膛扩散系数关联式。According to the two-dimensional cold model experiment on the large-scaling circulating fluidized bed, have simulated the actual coal-feeding diffusion and blending in the furnace, and defined the relating formula of coal-feeding diffusing-coefficient in the furnace by using changing parameters： diameter of bed inventory, diameter of tracer granule material,superficial velocity and static height of Circulating Fluidized Bed.

关 键 词：循环流化床 给煤扩散 二维冷态试验
