Aim of the project, carried out in co-operation with the Institut für Verfahrenstechnik und Dampfkesselwesen (IVD) of the University of Stuttgart, was to determine the most promising configuration out of the multitude of gasification pilot plants currently existing. Important evaluation criteria were the fuel demand, the gas quality, the emissions and incurring residues as well as the economic aspects of the operation.

On the basis of the investigation, measurements and detailed examinations of the tar production, the possibilities for optimising the processes tested were determined. Main goal was to improve gas quality by primary measures (e.g., tar content, heating value). The secondary flue gas cleaning systems which may be used in the respective facilities were also planned, optimized and evaluated economically. As a result of the examination, overall plant configurations are determined with which, in the current state or after further optimization, process gas for gas engines or -turbines can be economically delivered in decentralized CHP facilities.
