Abstract:
The use of biomass, whether wood or waste materials, represents an opportunity to reduce dependence on fossil fuels. Using dual fluidized bed (DFB) steam gasification technology for conversion of biomass, biogenic residues and waste is a possible approach to exploit this potential. A demonstration-scale 1 MW gasification plant with subsequent product gas and flue gas cleaning has been constructed at the Syngas Platform Vienna. The performance of this plant during its first continuous operation was evaluated in this study by analyzing temperature and pressure profiles recorded over a period of nearly 6 hours of continuous operation and by evaluating various performance indicators, such as steam-to-fuel ratio, gasification temperatures, and product gas composition. The resulting data sets were compared with existing results from the 100 kW pilot plant at TU Wien. The discrepancies found and their avoidance is discussed. In addition, this paper highlights the mechanical challenges encountered during commissioning, such as high temperatures at the fabric filter and additional condensate drain in steam supply pipes, and identifies potential challenges during the installation and operation of future gasification plants.
