A Methodology for Measuring the Heat Release Efficiency in Bubbling Fluidised Bed Combustors
Energies, 2020 Differences in the densities of bed material and—especially biogenic—solid fuels prevent an ideal mixture within bubbling fluidised bed (BFB) combustors. So, the presence of fuel particles is usually observed mainly near the surface of the fluidised bed.

Modeling and Simulation of a lab-scale Fluidised Bed [PDF]
Modeling, Identification and Control, 2002 The flow behaviour of a lab-scale fluidised bed with a central jet has been simulated. The study has been performed with an in-house computational fluid dynamics (CFD) model named FLOTRACS-MP-3D.

Enrichment of Limestone Used in the Desulphurisation of Fluidised-Bed-Boiler Flue Gases
Adsorption Science & Technology, 2021 In this work, we analysed the impact of adding several previously untested Sorbacal calcium-based substances to the raw limestone that is currently used for dry desulphurisation of brown-coal fluidised-bed boilers.

Liquid injection in a fluidised bed: Temperature uniformity
Chemical Engineering Science, 2022 Liquid injection in fluidized beds occurs in well-established industrial processes as fluid coking, spray fluidzed bed granulation and condensed mode gas-phase polymerisation. These processes still suffer performance issues due to their complex nature, where liquid injection adds even more complexity. In this work, the effect of liquid injection on the

Fluidised Bed Gasification of Diverse Biomass Feedstocks and Blends—An Overall Performance Study
Energies, 2020 The aim of this work is to investigate the fluidised bed gasification of several pure and blended feedstock prepared in the form of pellets: oak bark, two bark/wheat straw blends (85/15 and 50/50 wt%) and lignin residue remaining from bioethanol ...

CFD-DEM Analysis of Particle Attrition in a Jet in a Fluidised Bed
EPJ Web of Conferences, 2017 In fluidised bed processes, the solids are in vigorous motion and thus inevitably subjected to mechanical stresses due to inter-particle and particle-wall impacts.
