Parameters and Energy Analysis of Biomass Gasification System

中文摘要英文摘要

我国的生物质资源储备丰富、来源广泛,且成本较低,因此具有极高的开发利用潜力.生物质气化可以有效地利用生物质资源,其合成气经过一系列变化合成甲醇燃料,可以有效地解决化石能源中存在的环境污染问题.采用热力系统计算软件搭建了生物质气化的系统模型,选取松木锯末作为进料生物质,采用空气-水蒸气作为气化介质,通过与文献对比验证了模型的准确性.最后对该生物质气化系统进行了参数分析与经济性分析.结果表明:当气化温度为800 ℃,空气当量比为0.24、水蒸气与生物质质量比为为0.8、氧气体积分数为31%时,此时该气化系统的性能最佳,合成气的热值可以达到最大值.该系统的气化效率为70%,碳转化率为85.2%.

With abundant reserves,wide sources,and low costs,China's biomass resources have extremely high potential for development and utilization.Biomass gasification can effec-tively utilize biomass resources,and its synthesis gas undergoes a series of changes to synthe-size methanol fuel,which can effectively solve the environmental pollution problems in fossil fuels.This article uses thermal system calculation software to build a system model for bio-mass gasification.Pine sawdust is selected as the biomass,and air water vapor is used as the gasification medium.The accuracy of the model is verified by comparing with literature.Fi-nally,parameter analysis and economic analysis are conducted on the biomass gasification system.The results show that when the gasification temperature is 800 ℃,the air equiva-lence ratio is 0.24,the steam to biomass mass ratio is 0.8,and the oxygen volumetric con-centration is 31%,the performance of the gasification system is optimal,and the calorific value of the synthesis gas can reach its maximum value.The gasification efficiency of this system is 70%,and the carbon conversion rate is 85.2%.
