The significance of gas release on the mixing of larger particles in bubbling fluidized beds

Fuel Processing Technology
The mixing of larger particles (e.g., fuel particles) in a bubbling fluidized bed is governed by buoyancy and drag, which correspondingly promote segregation and internal circulation.

Determination of Cluster Hydrodynamics in Bubbling Fluidized Beds by the EMMS Approach

Journal of Chemical and Petroleum Engineering, 2011
The local solid flow structure of gas-solid bubbling fluidized bed was investigated to identify and characterize the particle clusters. Extensive mathematical calculations were carried out using the energy-minimization multi-scale (EMMS) approach for ...

Repurposing Fly Ash Derived from Biomass Combustion in Fluidized Bed Boilers in Large Energy Power Plants as a Mineral Soil Amendment

Energies, 2020
This research involved studying the physico-chemical parameters of fly ash derived from the combustion of 100% biomass in bubbling and circulating fluidized bed boilers of two large energy plants in Poland. Chemical composition revealed that ash contains

Experimental verification of the efficiency of selective non-catalytic reduction in a bubbling fluidized bed combustor

Acta Polytechnica, 2022
Controlling nitrogen oxide (NOX) emissions is still a challenge as increasingly stringent emission limits are introduced. Strict regulations will lead to the need to introduce secondary measures even for boilers with bubbling fluidized bed (BFB), which ...

Silicon Chemical Vapor Deposition on macro and submicron powders in a fluidized bed [PDF]

, 2007
Titanium oxide (TiO2) submicron powders have been treated by Chemical Vapor Deposition (CVD) in a vibro-fluidized bed in order to deposit silicon layers of nanometer scale on each individual grain from silane (SiH4).

Modeling of Magnetic-Field-Assisted Fluidization: Model Development and CFD Simulation of Magnetically Stabilized Fluidized Beds

KONA Powder and Particle Journal, 2014
Magnetic-field-assisted fluidization is starting to be considered as a viable alternative to standard fluidized beds for those operations (such as particle separations, filtration, adsorption) in which the solid phase can be made of magnetic particles or,
