Experimentelle und mathematische Modellierung der Festbettvergasung am Beispiel der Gleichstromvergasung von Holzhackschnitzeln
Abstract
dc:description.abstractThe aim of the present work about experimental and mathematical modelling of moving-bed-gasification was to increase the transparency of the process. At Dresden University of Technology a gasifier with a high number of measuring points was used. Two-dimensional profiles of temperature and gas-concentrations were analysed. Samples of particles taken out of the reactor gave information about drying, pyrolysis and char-reactions. A commercial CFD-software was modified for the special application of fixed-bedgasifiers by subroutines. Comparisons of the results of experiment and simulation showed the constitutive process with its significant reaction-behaviour. By variation of different parameters, important influences were discussed.
