Investigations on Inorganic Matter in DFB Biomass Steam-Gasification Plants in Güssing/Austria and Oberwart/Austria

F. Kirnbauer, J. Kotik & H. Hofbauer
Dual Fluidized Bed Steam Gasification is a promising technology for the utilization of biomass and has been demonstrated on an industrial scale since 2002. The solid­solid interactions of inorganic matter such as bed material (e.g. olivine), additives (calcium oxide and dolomite) and biomass ash with respect to catalytic properties for tar reduction have been studied. Two plants with different configurations concerning ash handling were analyzed to understand the different effects and mechanisms resulting from different...
