Experimental investigation of spout incoherence in a spouted bed
Chemical Engineering Journal, 2021Abstract Spout incoherence is a typical instability phenomenon in spouted beds, in which the particles in the spout region move upward as groups, leading to poor spouting stability and efficiency. In this paper, the moving particle blockage in the spout region is measured to quantify the spout incoherence for the first time, by means of depicting the

Combustion and Flame, 1978
Abstract The use of spouted beds for burning poor fuels is explored both experimentally and theoretically, following previous work on burners with massive enthalpy recirculation. The spout passes through the combustion zone and becomes part of a toroidal vortex of the bed material which acts as an effective mobile heat exchanger between hot products ...

Spout deflection in spouted beds and countermeasures: A review
Powder Technology, 2021Abstract Spouted beds operation quality and stability often suffer from spout deflection, which means the spout channel shows a lateral movement instead of vertical spouting. A comprehensive review about spout deflection in spouted beds has not been reported yet.

The Canadian Journal of Chemical Engineering, 1962
AbstractThe first commercial spouted bed driers have been installed in Canada and one has been used to dry three types of peas, lentils and flax. The data obtained from this drier have been compared and correlated with previous drying studies in various laboratory spouted bed driers.

Spout diameters in full and half spouted beds
The Canadian Journal of Chemical Engineering, 1998AbstractA fiber optic probe has been used to measure spout diameters in a half‐column and a full‐column based on the significantly higher counts of output electric pulses in the spout region than in the annulus. The flat wall of a semi‐cylindrical spouted bed column was found to cause considerable distortion of spout shapes which became approximately ...

Prediction of minimum spouting velocity in spouted bed
Asia-Pacific Journal of Chemical Engineering, 2009AbstractMinimum spouting velocity was measured using different bed heights with six different particles. A statistical analysis of the reported correlations for minimum spouting velocity based on the present and literature data was made and the estimated.

SPOUTED AND SPOUT-FLUIDIZED BEDS FOR GRAM DRYING
Drying Technology, 1989ABTRACT The objectives of this work are to analyze the drying performance of conical-cylindrical spouted bed (CSB) dryers for three different grains (rice, corn and wheat), and to compare the drying efficiency of CSB dryers with that of spout-fluid bed (SFB) dryers.

Spouting behaviour of binary mixtures in square-based spouted beds
Particuology, 2019Abstract From experiments, the influence of the physical characteristics of different binary mixtures of solids on the spouting regime of a pyramidal square-based spouted bed reactor is assessed. The applied methodology permits a more precise evaluation of the effects of the tested variables (diameter, density, sphericity) on the response variables ...

Since the pioneering text by Mathur and Epstein over 35 years ago, much of the work on this subject has been extended or superseded, producing an enormous body of scattered literature. This edited volume unifies the subject, pulling material together and underpinning it with fundamental theory to produce the only complete, up-to-date reference on all ...

Publisher Summary The full benefits of fluidization, although with coarse and uniform-sized particles, are not always realized because of the growth of large bubbles in the bed causing a tendency toward slugging. This limitation of fluidized beds can be overcome if the gas enters the bed through a small opening at the center of a conical base instead
