为了提高生物质能的利用效率以及生物质气化合成气的品质,基于AspenPlus模拟平台,以松木、玉米秸秆和木屑为气化原料,对生物质气化特性进行了研究并对气化过程进行了分析。计算了空燃比为0.7～2.3、生物质含水率为30%条件下的气化炉运行温度、合成气低位热值和效率等主要气化过程性能指标,并通过提高气化剂温度、干燥生物质原料等方法对生物质气化过程进行了优化分析。结果表明,生物质种类及其含水率对气化过程性能有较大的影响;降低生物质含水率、提高气化剂温度有利于提高气化过程的效率和合成气低位热值。
In order to improve the utilization efficiency of biomass energy and the quality of biomass gasification syngas, gasification characteristics of biomass were studied based on AspenPlus simulation platform with pine wood, corn stover and sawdust as the gasification raw materials, and the gasification process was carried out Analyzed. The performance indexes of main gasification process such as gasifier operating temperature, low calorific value and efficiency of syngas were calculated with the air-fuel ratio of 0.7-2.3 and the biomass moisture content of 30%. By increasing the temperature of gasifier and drying Material raw materials and other methods of biomass gasification process optimization analysis. The results showed that biomass types and their moisture content had a great influence on the gasification process. Reducing the biomass moisture content and increasing the temperature of the gasification agent were helpful to improve the gasification efficiency and the low calorific value of the syngas.
