The combination of carbon capture and storage technology with biomass as a carbon neutral fuel could provide a very effective method of CO2 disposal, hence the interest on biomass oxy-fuel combustion technology. Various biomass samples combustion have been studied on a single particle device with high speed video recording. The images set new evidences on the differences on ignition, volatile release and combustion, char combustion and burnout time in air and oxy-fuel conditions. The study reflects the effects of O2/CO2 concentration on the overall combustion performance. A worsening of the combustion and delayed ignition is observed when replacing N2 by CO2. As Oxygen concentration increase burnout times are reduced. Changes on the shape of the char have been observed during char combustion. Particles were observed to lose the fibrous shape and get more rounded during the last steps of the combustion with a reduction of the aspect ratio.
