Techno-Economical Analysis for a 3 MWth Gasification Plant Revamping: Use of Enriched Air and Steam as Gasifying Agent
(2010)
An assessment of the revamping of a 3 MWth atmosphericpressure bubbling fluidized bed biomass gasifier was made in order to study the technoeconomical viability of changing the gasifying agent from air to a mixture of ...

Influence of the Stoichiometric Ratio on Tar Composition during Fluidized Bed Gasification
(EUBCE, 2017)
Fluidized bed gasification is a promising technology for the energetic valorization of biomass and wastes. However the presence of heavy tars limits the use of the gas to applications where the gas is not cooled. Several ...

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 ...

Gasification of Char from Dried Sewage Sludge with Steam and CO2 in Fluidized Bed
(EUBCE, 2010)
Kinetics of gasification of char obtained from dried sewage sludge (DSS) with steam and CO2 have been measured in a laboratory fluidized bed (FB) reactor at temperatures between 800 and 950 ºC with steam and CO2 . ...

Investigation of Tar Properties for Tar Removal by Scrubbing
(EUBCE, 2010)
A new concept to remove tar by scrubbing from biomass gasification gas is investigated. The concept is based on a system capable to remove the tars in two sequential stages: heavy tars are removed in a first hot absorber ...

Heavy Metals Partitioning during Thermal Conversion of Sewage Sludge in a Fluidized Bed under Conditions Relevant for Pyrolysis and Gasification
(EUBCE, 2017)
There is a growing concern on the final disposal of urban organic wastes, such as municipal solid waste (MSW) and sewage sludge (SS), since they constitute an available energy and material source currently not efficiently ...

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 ...
