an experiment using electric resistance analogic method was carried out to study the surface abrasion of the internals in circulating fluidized beds (cfb).
利用自行开发的电阻模拟法,对循环流化床圆柱形内构件表面受气固两相流磨损的情况进行实验研究。
the surface hardness, parallel-to-grain compression, bending strength and elasticity modulus increased by 100%, and the surface abrasion increased by 300% when the liveweight growth rate was over 50%.
the method described in the paper may be used to develop an on-line testing system for the surface abrasion of cfb internals.
