Modeling of Gasification of Wood in a Circulating Fluidized Bed

Abstract

An one-dimensional mathematical model for describing the fluidization and the gasification reactions of wood in a circulating fluidized bed combustor has been developed. The mathematical model consists of modules to calculate the fluiddynamic parameters, the kinetics of the gasification reactions and the temperature in the CFBC. It is shown that in the pilot plant measured pressure drop and the temperatures correspond very well with the calculation.
