摘　　要：在试验条件下,考察反应温度、升温速率、物料颗粒大小等因素对蔗渣在水蒸气中的热解气化特性的影响。试验结果表明,热解终温越高,物料粒径越小,越有利于产生高质量的热解气。热解终温是热解气化过程主要的决定因素,在先到达热解终温,再通入水蒸气的操作条件下,升温速率的改变对气化效果的影响并不突出。试验在最佳条件(采用粉末物料,在1000℃下进行热解)下,可以得到高热值(10MJ/m3)合成气和较高的产气率(1.7m3/kg)。In the experiment using steam as gasification agent, we studied the factor affecting pyrolysis of bagasse,such as final pyrolysis temperature, heating velocity, particle size. According to the experiment, higher temperature and smaller size of feedstock will be propitious to produce gas with higher heating value. Among the operating conditions of pyrolysis, temperature is the determinating factor in the reacting process, and the change of heating velocity does not have much impact on the gasification. Under the best conditions(using powder bagasse, temperature 1 000 ℃),we can get producer gas with high heat value of 10 MJ/m3 and ratio of producer gas of 1.7 m3/kg.
