摘要：The heat transfer mechanism between biomass particles and ceramic ball heat carriers was the subject of this study. The convective experiments between the ceramic balls and air, as opposed to heat transfer experiments involving the solid carriers and biomass particles and pyrolytic gaseous product, were conducted using the particles-separating apparatus. The convective heat transfer principle between one solid carrier and air as well as between biomass and solid carriers were discussed. According to the experimental data, the convective heat transfer coefficient of one ceramic ball was analyzed based on the theoretical and non-dimensional analytical methods, which were 291.3 W/(m2· °C) and 200.3 W/(m2· °C) respectively. The non-dimensional equations of biomass particles and ceramic balls were also determined via the heat balance analysis method and the non-dimensional equation, which were Nuc=176+0.079 Recand Nub=22.97+0.2251 Rebrespectively.
