Summary: | This study examines the pyrolysis of a single cylindrical wood particle using Particle Image Velocimetry (PIV). The pyrolysis was carried out in the ATR 01/600 pyrolysis reactor designed for this purpose. The experimental setup presented in this study is capable of effectively characterizing the intensity of pyrolysis based on velocity distribution in the vicinity of wood particles. The results of the gas velocity distribution indicate the formation of a gas cushion caused by the evaporation of moisture and devolatilization. Higher heating rates increase the intensity of degassing and the thickness of the gas cushion around the particle and may temporarily slow down the intensity of convective heat transfer to the interior of the particle. |
