摘要: The influence from structural changes, heat transfer properties of dry wood and pyrolysis mechanism on the large particles were studied. Measurements temperature distribution mass loss performed cylindrical samples birch during in an inert atmosphere at 700°C. A model was modified to include changes. Comparisons measurements simulations show that inclusion a shrinking reduces time substantially. varying interior heating rate found choice mechanism. Of four mechanisms literature, only one be agreement with measurements.
