THE LATERAL DISPERSION CHARACTERISTICS OF SOLID WASTE PARTICLES IN ICFB
流化床中废弃物颗粒的横向扩散特性

In the present paper, based on the experimental data, the lateral dispersion coefficients of five kinds of solid waste particles are calculated in the ICFB and the bubbling bed. The results indicate that the following factors influence dispersion coefficients: the distortion extent, the density and the size of the particles; the shape of the air distributor and the mode of air distribution. The movements of light particles follow the law of diffusion; on the other hand, the movements of heavy particles do not. The particles' lateral dispersion characteristics are described and explained briefly by the interaction of gas-particle flows and waste particles with various matter properties.
