Confined fluidised bed porosity in the light of bubbling-bed models [PDF]

open access: yesChemical and Process Engineering, 2012
Abstract Based on hydrodynamic data, Kato-Wen and Kunii-Levenspiel bubbling-bed model parameters, supplemented with assumptions characteristic for tested confined fluidised bed, were analysed. The calculated bubble diameters and the bed composition proved essential influence of inter-particle space of packed compacted component onto fluidisation ...

Biomass thermal conversion : pelletisation of lignocelluloses and the effect on the gasification process [PDF]

open access: yes, 2012
Agricultural residues and energy crops constitute an important part of the energy chain although they are not being used extensively in the energy generation processes since they are associated with disadvantages such as low bulk and energy densities ...

Multifluid Eulerian modeling of dense gas–solids fluidized bed hydrodynamics: Influence of the dissipation parameters [PDF]

open access: yes, 2008
Computational fluid dynamic (CFD) models must be thoroughly validated before they can be used with confidence for designing fluidized bed reactors.

Fluidization of Group B particles with a rotating distributor [PDF]

open access: yes, 2008
A novel rotating distributor fluidized bed is presented. The distributor is a rotating perforated plate, with 1% open-area ratio. This work evaluates the performance of this new design, considering pressure drop, Δp, and quality of fluidization.

Case Study Comparison of Bubbling Fluidised Bed and Grate-Fired Biomass Combined Heat and Power Plants

open access: yesChemical Engineering Transactions, 2016
As woody biomass is gaining importance as an energy source for electricity and heat we need to investigate with scientific methodology the main problems that occur with biomass boiler systems.

EFFECT OF OPERATING PARAMETERS ON THE MINIMUM FLUIDISATION VELOCITY OF AN INCLINED FLUIDISED BED [PDF]

open access: yes, 2003
Fluidisation phenomena in an inclined fluidised bed (IFB) systems are poorly understood and receive less attention as compared to that of vertical fluidised bed although in practice there are many fluidised bed systems not vertically oriented.

Bubble Behaviour in Fluidised Beds at Elevated Pressures

open access: yesMacromolecular Materials and Engineering, 2011
AbstractLow density polyethylene and polypropylene are produced at large scale via the Unipol process. In this process catalyst particles are fluidised with monomer gas and grow into polymeric particles up to a size of 1 mm. The process is operated at 20–25 bar.

Pilot-scale calcination of limestone in steam-rich gas for direct air capture

open access: yesEnergy Conversion and Management: X, 2019
A novel polygeneration concept, which has been proposed recently, comprises a fuel-cell calciner integrated system in order to produce electricity and lime which can be used for direct air capture (DAC) to remove CO2 from the atmosphere.

The influence of multiple tubes on the tube-to-bed heat transfer in a fluidised bed [PDF]

open access: yes, 2010
There have been few studies modelling both flow and heat transfer in fluidised beds. The kinetic theory of granular flow (KTGF) has been used for flow prediction in the past without heat transfer modelling.
