Abstract:

The authors present results of an experimental determination of the aerodynamic drag, density, velocity and dwell time of disperse material in a circulating fluidized bed. When the gas filtration velocity exceeded 8-9 m/sec, the particles moved upwards over the entire channel cross section, at all levels, and the pressure fluctuations practically vanished. For lower filtration velocity and all material supply rates the pressure fluctuations increased, and for gas filtration velocity ≈ 3-6 m/sec and less the bed was clearly divided into a central zone in which the disperse material was transported upwards by the gas, and a peripheral zone where it was predominantly driven along the walls in the form of jets and vortices, sometimes pouring down as a continuous stream to the center of the channel, periodically disrupted by the gas.
