Original Article


Because of the limited resources of fossil fuels the efficient use of renewable energy is gaining importance. Renewable energy from biomass reduces CO2 emissions, which is a necessity to protect the global climate. In the dual fluidized bed steam gasifier, wood chips are converted to producer gas, which is further used for heat, power, and/or other product generation very successfully. This work presents alternative feedstocks for this process: biomass wastes, such as waste wood and bark. Waste wood and bark have been gasified successfully and results of these experiments in a pilot plant are presented in this paper.

We want to thank the team of the Notified Testing Laboratory for Combustion Systems at the Vienna University of Technology for their support. Gasification of waste wood is carried out in the frame of the Bioenergy2020+ project “C-II-1-4 Industrial Residues”. Bioenergy2020+ is funded within the Austrian COMET program, which is managed by the Austria Research Promoting Agency FFG. The financial support is gratefully acknowledged.
