Gasification of waste wood and bark in a dual fluidized bed steam gasifier Veronika Wilk & Hannes Kitzler & Stefan

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.
