Ignition behavior of single coal particle in a fluidized bed under O2/CO2 and O2/N2 atmospheres: A combination of visual image and particle temperature
(Elsevier, 2014)
Single coal particle ignition behavior was studied in a two-dimensional (200 mm × 20 mm × 400 mm) fluidized bed under O2/N2 and O2/CO2 atmosphere with O2 volume concentration in the range of 0–40%, by a combination of ...

Modeling biomass char gasification kinetics for improving prediction of carbon conversion in a fluidized bed gasifier
(Elsevier, 2014)
Gasification of biomass in a fluidized bed (FB) was modeled based on kinetic data obtained from previously conducted thermogravimetric analysis. The thermogravimetric analysis experiments were designed to closely resemble ...

Downstream evolution of unconfined vortices: mechanical and thermal aspects
(Cambridge University Press (CUP), 2002)
We present a numerical study of the downstream evolution (mechanical and thermal) of vortex-jet cores whose velocity and temperature fields far from the axis match a family of inviscid and non-conducting vortices. The ...

Poultry Litter Gasification in a Fluidized Bed Reactor: Effects of Gasifying Agent and Limestone Addition
(American Chemical Society, 2016)
Air and air-steam gasification of poultry litter was experimentally studied in a laboratory scale bubbling fluidized bed gasifier at atmospheric pressure using silica sand as the bed material. The effects of equivalence ...

Techno-economic and operational assessment of concentrated solar power plants with a dual supporting system
(Elsevier, 2021-11)
This study evaluates the benefits of integrating a full renewable dual back-up system (biomass and Thermal Energy Storage (TES)) in Concentrated Solar Power (CSP) plants. Two plants of 50 MWe capacity each are modelled ...

Effect of CO2 on oxy-fuel combustion of coal-char particles in a fluidized bed: Modeling and comparison with the conventional mode of combustion
(Elsevier, 2016)
A char combustion model is developed to study the effect of CO2 on the combustion of coarse char particles under oxy-fuel conditions in a fluidized bed (FB). It is a transient one-dimensional model, taking into account the ...

Tar conversion of biomass syngas in a downstream char bed
(Elsevier, 2020)
The catalytic conversion of biomass-derived tars over char during long tests (over 6 h) is studied. The syngas is generated in a steam-blown fluidized-bed gasifier employing wood pellets and conducted to a second tubular ...

Application of biomass gasification fly ash for brick manufacturing
(Elsevier, 2011)
Biomass gasification technology offers an attractive way to use low-grade fuels in energy production with high efficiency and low environmental impact. However, an issue calling for further development is the volume and ...

On the comprehension of the gas split in loop seal devices
(Elsevier, 2022)
Gas distribution through the chambers of a loop seal in circulating fluidized bed (CFB) units is still difficult to predict and often misunderstood. Dedicated experiments were carried out in an isolated loop seal to assess ...
