The Graz University of Technology (TU GRAZ) participates in FlashPhos with the “Thermal Energy Systems and Biomass” group of the Institute of Thermal Engineering (IWT). The group has extensive experience in experimental and numerical research on the thermal characterisation of industrial furnaces and thermal conversion of biomass as well as fossil fuels. Research focus of the IWT is primarily combustion, gasification and pyrolysis, as well as the development of innovative waste heat recovery systems and the optimisation of solid oxide fuel cells (SOFC). The group has achieved a leading position in multi-scale descriptions of thermo-chemical processes, including the molecular, particle and reactor level, employing detailed reactions schemes and computational fluid dynamics (CFD) simulations. It works in close cooperation with leading developers and manufacturers of steel-based technology, glass-based technology, of industrial furnaces, and of biomass combustion, gasification and pyrolysis plants. It is closely cooperating as a key partner with the Austrian bioenergy competence centre BIOENERGY 2020+.
