两种生物质燃烧性能及燃烧动力学特性的研究

摘要

采用热分析仪对内蒙古地区两种产量较大的生物质—玉米秸秆和小麦秸秆进行了热重实验,比较了燃烧特性,计算了燃烧反应动力学参数.结果表明挥发份的析出燃烧阶段是两种生物质燃烧的主要阶段.小麦秸秆的综合燃烧特性比玉米秸秆好.两种生物质在挥发份析出燃烧阶段的活化能及频率因子均高于焦炭燃烧阶段的活化能及频率因子.%By using thermal analyzer,two types of larger production of biomass from Inner Mongolia Re gion was performed thermogravimetry experimentation analysis.The differences in combustion properties were compared,and the combustion kinetic parameters were calculated.The results show that the volatilization separation and combustion phase is the main one in the process of combustion of two types of biomass.The comprehensive combustion property of wheat straw is better than that of corn straw.The activation energy and frequency factor are higher at the volatilization separation and combustion phase than those at the coke combustion phase.
