Computer Controlled Fluidization and Fluid Bed Heat Transfer Unit

Details

The Computer Controlled Fluidization and Fluid Bed Heat Transfer Unit, "TTLFC", has been designed by EDIBON to provide visual and quantitative results related to the flow of air through a packed bed and a fluidized bed made of granular material. It provides clear experimental possibilities for the research of the heat transfer in a fluidized bed. The main element is a glass chamber, lit from behind, where a granular material is contained. A fluid (air), supplied to the bed through the bottom thanks to a distributor, passes through that material. Nine different distributors are provided so that they can be compared during the process. They have different number of orifices, different sizes of orifices and different distribution of orifices. Air is expelled through the upper side of the chamber, crossing a filter that removes the particles that may have been dragged by the air when crossing the bed before releasing it to the atmosphere. When the air speed is slower that the so-called expansion rate, the flow only crosses the fixed bed. When the speeds are faster than that expansion rate, the bed is softened, so that the state of the solid particles change, being suspended and form
