Studies on Ash Behavior during Co-Combustion Of Paper Sludge in Fluidized Bed Boilers Untersuchung des Ascheverhaltens bei der Mitverbrennung von Papierschlammen in Wirbelschichtfeuerungen Von der Fakultät Maschinenbau der Universität Stuttgart Zur Erlangung der Würde eines Doktors der Ingenieurwissenschaft (Dr.-Ing.) genehmigte Abhandlung Vorgelegt von Beatrice Coda Aus Taranto, Italien Hauptberichter Prof. Dr.-Ing. K.R.G. Hein Mitbericher: Prof. Dr.-Ing. H. Spliethoff Mündliche Prüfung: 25/09/2003 Institut fuer Verfahrenstechnik und Dampfkesselwesen, Universitaet Stuttgart 2004 Preface The present doctoral thesis has been performed in the framework of the EU research project “ Reduction of Toxic Emissions from Co-Combustion of Coal, Biomass and Waste in Fluidised Bed” (EU Contract No. JOF3-CT97-0191). The main aims of the project were the widening the spectrum of fuels utilised by coal-fired, coal-straw fired, biomass-fired fluidised bed boilers, the improvement of the potential to use energy-containing residues, and the assessment of the environmental impact of waste co-firing by investigating in particular the toxic trace metals emissions. A substantial part of this thesis represents the contribution of the Institute of Process Engineering and Power Plant Technology (IVD), University of Stuttgart, Germany, to this EU project, especially as far as experimental results are concerned.
