摘要为了提高生物质燃气热值，开发一种新型热管生物质气化炉．结合质量平衡、能量平衡和化学反应动力学，建立热管生物质气化炉的动力学机理模型，最后通过试验进行验证．试验结果、模拟结果和其他类型气化炉相关数据对比分析表明：动力学机理模型与试验结果能较好地吻合；与用空气直接供热气化的气化炉气体组分和热值比较，用热管生物质气化炉得到的气体组分中氢气体积分数较高，约是用空气直接供热气化的10倍，热值是用空气直接供热气化的2～3倍．

Abstract：A novel heat pipe biomass gasifier was developed to improve the heating value of gas produced. Based on the mass balance, energy balance and dynamics of chemical reactions, a kinetic model was developed to simulate the process of biomass gasification and experiments were performed. By testing and simulation it shows that the kinetic model is consistent with testing results. By comparing the results of the gas composition and heating value with those produced by direct heat supply using air, it is found that hydrogen content in gas composition produced in the heat pipe biomass gasifier is approximately ten times of that in direct heat supply gasification using air.

Key words： hiomass gasification heat pipe bed temperature heating value
