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.

Effect of fluidised bed drying on ginsenoside content in hairy root cultures of Panax ginseng C.A. Meyer

open access: yesIndonesian Journal of Biotechnology, 2023
Korean Ginseng (Panax ginseng C.A. Meyer) is a high‐value herb with many pharmacological benefits due to its primary active compound, ginsenosides. The most ginsenosides are known to be thermolabile and susceptible to degradation at high‐temperature ...

Computational Modelling of Gas-Solid Hydrodynamics and Thermal Conduction in Gasification of Biomass in Fluidized- Bed Reactor

open access: yesChemical Engineering Transactions, 2017
A computational fluid dynamic model is developed to describe the fluid–particle interaction inside a fluidised bed reactor. The proposed gasifier reactor is 5 kW self-sustaining fluidised bed with 500 mm height and 127 mm diameter.The selected feedstock ...

CFD modelling of the fast pyrolysis of biomass in fluidised bed reactors: Modelling the impact of biomass shrinkage

open access: yes, 2009
The fluid–particle interaction and the impact of shrinkage on pyrolysis of biomass inside a 150 g/h fluidised bed reactor is modelled. Two 500 m in diameter biomass particles are injected into the fluidised bed with different shrinkage conditions.

Improving of drinking water quality by remineralisation

open access: yesActa Chimica Slovenica, 2015
The reason of low mineral content in source water is that it originates in the poor soluble mineral geological structures. There are more areas with very soft low-mineralized water in Slovakia.

Recovery of Cenospheres and Fine Fraction from Coal Fly Ash by a Novel Dry Separation Method

open access: yesEnergies, 2020
Aluminosilicate microspheres are a valuable fraction of coal fly ash with diverse applications due to their low density. Currently, there is no efficient and ecologically rational method of cenosphere recovery from fly ash.

Gaseous emissions during concurrent combustion of biomass and non-recyclable municipal solid waste [PDF]

open access: yes, 2011
Background: Biomass and municipal solid waste offer sustainable sources of energy; for example to meet heat and electricity demand in the form of combined cooling, heat and power. Combustion of biomass has a lesser impact than solid fossil fuels (e. g.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

CFD Investigation of Particle Temperature in Fluidised Bed Solar Receivers

open access: yesSolarPACES Conference Proceedings
This study investigates the influence of fluidised bed solar receiver geometries and fluidisation velocity on particle temperature distribution and bed performance, with a focus on evaluating the feasibility of using a square shape for fluidised bed ...

Effect of hydrodynamic parameters on the oxidative desulphurisation of low rank coal

open access: yesInternational Journal of Coal Science & Technology, 2018
In this paper, the desulphurisation of high sulphur low-rank coal is proposed as a raw material for pulverised coal injection technology. Therefore, the influence of oxidant linear velocity and the size of the coal grain was investigated in a fluidised ...
