Descripcion

In this PhD thesis, the flow stability in a laboratory three-dimensional prismatic spouted bed is investigated both experimentally and in CFD-DEM simulations. Liquid is injected in bottom-spray configuration with the aim of a homogeneous distribution of the coating suspension on the whole particle bed. The range of stable spouting is increased by the installation of two parallel draft plates. Nevertheless, the instable spouting regime is found to be advantageous for obtaining a homogeneous coating as the draft plates prevent the mixing in the depth of the apparatus. In addition to the investigations on laboratory scale, the residence time behavior in a continuous pilot scale spouted bed is characterized using a novel tracer method with magnetizable particles. The back-mixing in the apparatus is reduced by the insertion of separation plates with defined transfer geometries.
