Abstract: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 291.3W/(m2?℃) and 200.3W/(m2?℃) 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+0.079Rec and Nub=22.97+0.2251Reb respectively. |
Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
