Gasification of biomass in fluidized bed: review of modelling
Paper i proceeding, 2009
Modelling of biomass gasification in bubbling and circulating fluidised bed (FB) is reviewed. The focus is on comprehensive fluidisation models, where semi-empirical correlations are employed to simplify the fluid-dynamics of the FB. The conversion of single fuel particles, char and gas reaction kinetics are dealt with, outlining the key phenomena that should be included in gasification models. An assessment of published models is presented and the need of further investigation is identified.
