摘　　要：为提高生物质炭化炉的炭化效率,采用间接加热炭化方式对粉碎后的废弃树枝进行炭化,研究一次进风量、炭化温度、炭化时间等因子对炭化效果的影响,优化炭化工艺参数。结果表明:控制炉内炭化温度约500℃、炭化时间保持12h左右、一次进风量为5 000mm2、烟囱高度为2m时,炭化收成率、碳素率和炭化物性能都维持在较高水平。A indirect heating carbonization method is used to carbonize the wood chip from trimmed branches, and some technological parameters that influence the carbonization are studied. The parame- ters are main air inlet, carbonization temperature and carbonization time. The aim of the experiment is to optimize the technological parameters of the carbonization in order to provide technical support to the improvement of the ecological environment and the recycling of the waste in agricultural production. The results show that carbonization yield rate, carbon rate and the charcoals performance are maintained at a high level when the carbonization temperature is controlled at about 500 ℃, the carbonized time is set at about 12 h, the main air inlet is set at 5 000 mm2 ,and the chimney height is 2 m.
