The theory of fluidised bed coating

The Chemical Engineering Journal, 1970
Abstract A general theory is presented to predict the rate of coating in a fluidised bed of polymer powders. The relations derived give the coating thickness as a function of residence time of the object in the bed, the thermal and the physical properties of the object, the gas flow rate, i.e.

Developments in fluidised-bed technologies

Applied Energy, 1988
Conventional mobile-particle beds have been developed in order to store heat (or cold) for satisfying industrial and/or air-conditioning requirements by the use of thermally-active particles in which the principal storage mechanism is latent heat. Also fluidisation has been achieved, both in air and in high vacua, using ultrasonic stimulation.

Slug flow in fluidised beds

Powder Technology, 1967
The paper begins by summarising theory and experimental data concerning the rate of rise of a large gas bubble or slug through an inviscid liquid in a vertical tube, or between two flat plates. Experimental data show that the theory can be used to predict the rise of slugs in fluidised beds.

Fluidised-Bed Granulation: A Chronology

Drug Development and Industrial Pharmacy, 1991
AbstractThis paper is a chronological survey of published work in the field of pharmaceutical fluidised-bed granulation. It begins with early experiments in the 1960s and continues to include all relevant published work up to 1990. To aid the reader find published material for further in-depth reading a cross reference to published articles on a ...

Circulating fluidised bed hydrodynamics

Powder Technology, 2000
Abstract Analysis is given for flow regimes in the riser of a circulating fluidised bed (CFB) in the range of gas velocities (2–8 m/s) and particulate solids fluxes (15–90 kg/m2 s) appropriate for a CFB combustor. It is shown that the simplest version of the core-annulus model gives the correct magnitudes of slip velocity and average solids hold-up ...

Fluidised beds clearing the air

Electronics and Power, 1985
The emotive question of `acid rain? has brought the combustion of coal under the microscope of public scrutiny and has increased interest in the concept of fluidised-bed combustion.

Gas distributor in fluidised beds

Powder Technology, 1978
Abstract Satisfactory performance of fluidised bed reactors in terms of bed characteristics, chemical conversion and power requirement for pumping the fluidising medium is influenced by the design features of gas distributors. In industrial practice multi-orifice types of distributors are frequently used.

Fluidised Bed Combustion

1984
Fluidised bed combustion (FBC) differs from both conventional stokers and pulverised fuel combustion in being applicable to a wide spectrum of modern coal-fired systems ranging from small industrial boilers and furnaces to large power generation units.

A circulating liquid fluidised bed

Chemical Engineering Science, 1988
Un schema decrit l'appareil constitue de deux longs tubes verticaux relies entre eux pour former une boucle fermee, l'alimentation par le haut par une injection en T est mise en circulation par un agitateur en tete du tube en ecoulement ascendant.

Fluidised bed gas distributors

Powder Technology, 1979
Abstract The literature on gas distributors for gas fluidised beds is reviewed from the point of view of stable operation of the bed. An equation is suggested relating the minimum value of the ratio of the distributor pressure drop for stable operation and the bed pressure drop to the aspect ratio of the bed.
