Abstract (EN): Batches of Pinus pinea char particles with average diameters of 2.2, 2.8, and 3.6 mm were burned in a bubbling fluidized bed at temperatures of 600, 700, and 750 °C, with a velocities ratio U/Umf = 9. The results show that only primary fragmentation occurs with an average fragmentation ratio of 1.5. No effect of the secondary fragmentation phenomena is observed. The increase in the number of particles in the bed because of fragmentation is accounted over the burning time, and its effect is evaluated on the determination of the global combustion resistance.
