Fluidised bed drying of soybeans
Journal of Stored Products Research, 2001The fluidised bed drying characteristics of soybeans at high temperatures (110-140 degrees C) and moisture contents, 31-49% dry basis, were modelled using drying equations from the literature. Air speeds of 2.4-4.1 m/s and bed depths from 10 to 15 cm were used. The minimum fluidised bed velocity was 1.9 m/s.

The expansion of gas-fluidised beds in bubbling fluidisation
Chemical Engineering Science, 1997The expansion of gas-fluidised beds has been examined in the range of Archimedes number from 100 to 105 using five grades of glass ballotini and two grades of lead shot of narrow size distribution, and Diakon particles of wide size distribution. A porous plastic distributor plate was used in beds of diameters 89 and 290 mm.

The process of fluidisation involves blowing warm air through small solid microspheres thus creating a liquid, without wetness. The warmth provides some important properties including reducing the metabolic rate in thermal injury which has a beneficial effect on mortality, modifying catabolism after surgery, providing gradual vasodilation in shock and ...

Proceedings of the Institution of Electrical Engineers, 1969
Use of electroheated fluidised beds is a fast-growing branch of electroheating, but this growth has been hampered because the models available hitherto were incomplete, in that they ignored flow and mode dependence and were unnecessarily complicated for the engineer concerned with practical industrial processes.

Thermal degradation of PMMA in fluidised beds
Waste Management, 2004In recent years, the production and consumption of plastics have increased significantly and wastes are commonly incinerated or dumped in a landfill. Plastics pyrolysis, on the other hand, may provide an alternative means for disposal of plastic wastes with recovery of valuable gasoline-range hydrocarbons or the monomer.

Characteristics of fluidisation behaviour in a pressurised bubbling fluidised bed
The Canadian Journal of Chemical Engineering, 2012AbstractThe experiments were carried out in a bench‐scale fluidised bed of 90 mm in diameter to determine the influence of pressure on fluidisation characteristics of Geldart A and B particles over the range of pressure 0.1–4.5 MPa. For Geldart B particles, the results indicate that minimum fluidisation velocity (umf) was found to decrease with ...

Abstract Induced particle circulation was studied in a 0.3 m diam. air fluidised bed of sand with central draught tubes of 0.2 m and 0.15 m diam. and 0.6 m and 1.2 m in length. A “two-dimensional” bed, 0.3 m in width, of similar cross-section, was also used to study catalyst particle circulation.

Circulating fluidised-bed combustion
Applied Energy, 1990Abstract A mathematical model for the steady-state combustion of char in a circulating fluidised bed (CFB) has been developed by taking into account the bed's hydrodynamic conditions, chemical-reaction rates, and combustion mechanism and the conservation of mass and energy. The model is an improvement over the simplified combustion model developed by

Fluidised beds as ‘coolth’ stores
Applied Energy, 1991Abstract High energy-density thermal storage at low temperatures is feasible using phase-change materials. Thus an energy-storage device has been conceived which uses water-absorbing cross-linked polymers, known as hydrophilic materials. These were produced in the form of particles, which can be hydrated.

Flow patterns in fluidised beds
Rheologica Acta, 1965The characteristics of the behaviour of the particles in a liquid fluidised bed in which the influence of the bubbles of fluid is small, depends at a particular liquid flowrate, on the size and size range of the particles.
