Abstract:

In the last years, the European Union has been focused on biomass as renewable energy source. Within the project ENEREED the reed (phragmites communis) from the Lake Neusiedl in Austria, near to Vienna, is examined as energy resource. To characterize the reed, different samples were taken and fuel analyses were done. After the characterization, reed was used in pelletized form as feedstock in a 100 kWth (reed input) dual fluidized bed (DFB) steam gasifier at Vienna University of Technology (VUT). To compare the gasification test with the standard fuel (softwood­pellets), a mixture of 50 kWth reed pellets and 50 kWth softwood pellets was gasified, too. The DFB gasifier was operated with olivine as bed material and steam as fluidization and gasification agent. The gasification temperature was 850°C and the steam to carbon ratio was 1.7 (kg/kg). Compared to softwood pellets the higher nitrogen and sulphur content of reed causes a higher NH3 and H2S content in the product gas. However, the gasification tests show that reed is a suitable feedstock for gasification plants.
