Title: Estimation of Minimum Spouting Velocity in a Rectangular Spouted Bed

Abstract

Here, a study was conducted to explore the effects of static bed height, nozzle diameter, cone angle, and particle properties on the minimum spouting velocity in a 4 in × 1 in rectangular spouted bed. Tests were conducted with various solids materials (including 871 μm HPDE pellets, 3.2 mm nylon beads, 707 μm glass beads, and 1.5 mm alumina spheres), two gas inlet nozzle diameters, and two cone angles. Experimentally obtained minimum spouting velocities were compared to existing published correlations developed for cylindrical spouted beds. In each case, it was determined that the existing correlations did not adequately predict the minimum spouting velocity for a rectangular spouted bed. A new correlation is proposed.

Minimum spouting velocity of flat-base spouted fluid bed

Journal Article Monazam, Esmail R. ; Breault, Ronald W. ; Weber, Justin ; ... - Particuology

Experiments were performed on spout characteristics of a cylindrical spout-fluidized bed (I.D. = 10 cm) with different static heights and two materials (Al₂O₃ and high density polyethylene). Results of minimum spouting velocity obtained in this study were compared with reported correlations for both spouted and spout-fluidized beds. Considerable discrepancies were found between the values obtained using different model equations as well as with respect to experimental results. Based on the Mathur–Gishler correlation, a new correlation is proposed for calculating the minimum spouting velocity that introduces the ratio U/U_mf. It was found that the minimum spouting velocity decreases with increasing fluidizingmore »« less

A Spouted Bed Reactor Monitoring System for Particulate Nuclear Fuel

Conference Wendt, D S ; Bewley, R L ; Windes, W E

Conversion and coating of particle nuclear fuel is performed in spouted (fluidized) bed reactors. The reactor must be capable of operating at temperatures up to 2000°C in inert, flammable, and coating gas environments. The spouted bed reactor geometry is defined by a graphite retort with a 2.5 inch inside diameter, conical section with a 60° included angle, and a 4 mm gas inlet orifice diameter through which particles are removed from the reactor at the completion of each run. The particles may range from 200 µm to 2 mm in diameter. Maintaining optimal gas flow rates slightly above the minimummore »« less

Hydrodynamic Characterization of a Shallow Rectangular Spouted Bed Using Bed Pressure Signals and Image Processing Methods

Journal Article Yang, Jingsi ; Breault, Ronald W. ; Weber, Justin M. - Industrial and Engineering Chemistry Research

To support the design of spouted bed reactors, experiments are performed in a rectangular spouted bed to measure the peak pressure drop (ΔP_max) and the internal and external spouting velocities (U_is and U_es). Four particle types spanning under Geldart D and B are used. U_is and U_es are measured from bed pressure drop and expansion ratio profiles, respectively, with the U_es/U_is ratio of each particle type obtained. Additionally, correlations predicting the ΔP_max of Geldart D and B particles are developed by reviewing published correlations and investigating the nozzle effect. Good prediction is achieved with a slope of 0.997 and anmore »« less

Hydrodynamics of sawdust and mixtures of wood residues in conical spouted beds

Journal Article Olazar, M ; San Jose, M J ; Llamosas, R ; ... - Industrial and Engineering Chemistry Research; (United States)

It has been proven that conical spouted beds allow for stable operation with sawdust and with wood residues, even with mixtures of these materials of wide particle size range and without being diluted with an inert solid. Peculiar hydrodynamic characteristics for sawdust have been observed; a great hysteresis in the pressure drop vs velocity curve, a pronounced peak of maximum pressure drop, and a difference between the velocity for which spout and fountain are formed and the velocity of the fully spouted bed. From the hydrodynamic study of sawdust, the ranges of the contactor geometric factors (cone angle, inlet diameter/basemore »« less

Stability and hydrodynamics of conical spouted beds with binary mixtures

Journal Article Olazar, M ; San Jose, M J ; Penas, F J ; ... - Industrial and Engineering Chemistry Research; (United States)

The application of conical spouted beds with binary mixtures of glass spheres of particle diameters between 1 and 8 mm, in stable operation regime and without segregation, has been studied. The effects of the contactor geometric factors (angle, inlet diameter), of the stagnant bed height, of the mixture composition, and of the gas velocity on bed stability and bed segregation have been analyzed. It has been proven that the correlations proposed in the literature for calculation of the hydrodynamics of spouted beds of cylindrical geometry are not suitable for evaluating the hydrodynamics of the operation with mixtures in conical contactors.more »« less
