Hydrodynamic Study Of A Circulating Fluidized Bed Used For Biomass Gasification Between 20 °C And 900 °C, Sébastien Pecate, Mehrdji Hemati, Mathieu Morin, Yilmaz Kara, Sylvie Valin

Fluidization XV

This work, carried out in the GAYA project frame and subsidized by ADEME, concerns the hydrodynamic study of a 60 kWth circulating fluidized bed pilot plant constructed at the Laboratoire de Génie Chimique in Toulouse for biomass gasification. In that process, biomass gasification and heating of fluidisation material (sand, olivine, catalyst…) which also acts as heat transfer medium, are performed in two separate reactors: a dense fluidized bed and a transported bed. Thermal energy, required in order to heat the fluidisation material, is supplied by the partial combustion of the char produced in the gasification reactor. The hydrodynamic study carried …
