摘    要:采用TG-DTG-DTA(热重-微分热重-差热)热分析联用技术研究了两种生物质的燃烧模式和燃烧特性.考察了着火温度、燃烧速率最大时温度、燃尽温度和最大燃烧速率等燃烧特征参数;计算了综合燃烧指数和燃烧动力学参数.结果表明,两种生物质在燃烧模式上存在差别,生物质的着火温度在280 ℃左右,燃尽温度在500 ℃左右,生物质的综合燃烧特性指数明显高于煤的综合燃烧指数,生物质的燃烧过程可以用一级动力学方程描述.

关 键 词:生物质  燃烧模式  燃烧特性  TG-DTA-DTG联用技术

Abstract:The TG-DTA-DTG thermal analysis technology was applied to study the combustion model and combustibility of two kinds of biomass.Combustion characteristics of two kinds of biomass were analyzed according to combustion characteristics parameters such as ignition temperature, peak temperature at maximum weight loss rate, burnout temperature, maximum rate of combustion etc.Kinetic parameters and combustibility parameters were calculated.It shows that combustion model of two kinds of biomass is different, and the ignition temperature is about 280 ℃, and the burnout temperature is about 500 ℃, and combustibility parameters of biomass is better than coal, and first order reaction model is appropriate to describe the combustion of biomass.
Keywords:biomass  combustion model  combustibility  simultaneous technology of TG-DTA-DTG
