Physical Characteristics of Fluidized Beds via Pressure Fluctuation Analysis
Original language description
During various applications of gas fluidized units, the state/quality of the fluidized bed of solids can change due to changes in operation conditions or variations in the gas or solid feed. An analysis method is developed and applied which employs spectra of the Fast Fourier Transform of measured pressure fluctuations within the fluidized bed. The procedure is based upon the spectral analysis of successive time series of pressure fluctuations reflecting the actual hydrodynamic state (regime) of the bed. Practical application of the method is illustrated for fluidization at ambient temperature and pressure of spherical particles (glass beads) as well as irregularly shaped particles (limestone, sulfated limestone, and dried sewage sludge), in an 8-cm ?ID fluidized bed. Using air, experiments were conducted with different fractions of the materials spanning a very wide range of 0.28 ? 4.5 mm.
