摘要: 为了研究固定床生物质气化炉的气化特性及其影响因素,优化气化工艺参数,利用Aspen Plus仿真系统及其全混流反应器(RCSTR)和收率反应器(Ryield)等,建立固定床生物质气化过程的动力学仿真模型,利用该模型分析气化温度、空气配比(AR)、水蒸气通入量(S/B)、原料含水率4个气化工艺参数及全混流反应器数量对气化过程的影响,并通过敏感性分析优化气化工艺参数。综合考虑上述气化工艺参数进行生物质气化过程仿真分析,获得优化的气化工艺参数为气化温度800℃,空气配比0.25,水蒸气通入量2.3。

Abstract: In order to study the enfulence factors of biomass fixed bed gasification for optimizing gasification process parameters, the kinetic simulation model of biomass gasification process was established by the Aspen Plus simulation system with its associated modules of RCSTR and Ryied reactors. The gasification process parameters, such as gasification temperature, air ratio(AR), water vapor intake(S/B) and biomass moisture content, and their effects on gasification process were analyzed through the kinetic simulation model. Then gasification process parameters were optimized by sensitivity analysis. Considering the above gasification process parameters, the simulation analysis of biomass gasification process was carried out, and the optimization parameters were gasification temperature 800℃, air ratio 0.25, and water vapor intake 2.3.
