Gasification of waste wood and bark in a dual fluidized bed steam gasifier

Abstract

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.
