摘　　要：建立Corex工艺熔融气化炉移动床区域冷态模型,通过对示踪颗粒层运动信息的跟踪、研究,得到移动床区域炉料的流动规律、死料柱几何形状及尺寸。分析移动床高度、风口气体总流量对死料柱高度及横截面积的影响规律。试验结果表明:根据炉料流动规律,熔融气化炉移动床区域可分为四个不同的子区域。移动床底部的死料柱形状呈半椭圆形。在其它参数不变的情况下,随着移动床高度的增加,死料柱高度及横截面积减小;当风口气体流量增加,死料柱高度及横截面积减小。Cold model of moving bed of Corex melter gasifier was set up. Flow pattern of solid,geometry and size of deadman were obtained by the trace of tracer particles in the moving bed. Furthermore,the effect of height of moving bed and gas flow on the height and cross- sectional area of deadman were studied. The results show that the moving bed can be divided into four subdomains according to velocity magnitude of solid particles. The stagnation zone with semi- elliptic geometry is formed at the central bottom of the moving bed. When other parameters are kept constant,the height and cross- section area of the stagnation zone decrease with the increase of moving bed height or total gas flow rate.
