摘要
基于AspenPlus模拟平台,对含水率分别为10%,20%和30%玉米秸秆气化过程进行模拟.计算了空燃比在1～2范围内变化时,气化过程的主要性能指标:合成气成分、合成气低位热值、碳转化率和气化效率.并把气化剂空气温度从25℃提高到250℃对玉米秸秆气化过程进行优化.结果表明:在空燃比小于1.6时,合成气低位热值和气化效率得到明显提高,大于1.6时,优化前后差别不大.此结论对生物质气化技术提供了有益的参考.
The gasification processes of cornstalks respectively contained moisture at 10% , 20% and 30% , were simulated on the basis of AspenPlus software. When the air-biomass ratio varies from 1 to 2, the main performance indexes of the gasification process were calculated, which include syngas molar fraction, syngas LHV, carbon conversion efficiency and gasification efficiency. Through increasing gasifying agent temperature from 25℃ to 250℃ , the gasification process optimization was made. The results showed that when the air-biomass ratio was less than 1.6, syngas LHV and gasification efficiency were enhanced obviously, but had no obvious changes at the ratio more than 1.6. The conclusions would be beneficial references to biomass gasification technology.
