摘　　要：本文通过热重分析法研究了生物质型材的燃烧特性,得出了生物质型材燃料的热失重曲线和热微分失重曲线,并通过公式拟合计算给出了相应的活化能和频率因子数值。从曲线还可以发现生物质燃烧的着火温度在280℃左右,当温度达到304℃时燃烧反应的反应速率最大。这说明生物质型材着火点低,活化能相对较高。为了保证生物质在气化炉中燃烧时为了有足够的产气量和较高的气化效率,氧化层的温度应保持在900℃左右,还原层的温度应保持在700℃左右,可以为生物质气化炉的优化设计提供了理论依据。In this paper,the combustion characteristics of biomass profile were studied by Thermogravimetric analysis,and the thermogravimetric curve and thermos-differential weight loss curve of biomass profile fuel were obtained.From the curve,it can also be observed that the ignition temperature of biomass combustion is around 280℃,and the reaction rate of the combustion reaction is the highest when the temperature reaches 304℃.This indicates that biomass profiles have a low ignition point and relatively high activation energy.In order to ensure sufficient gas production and high gasification efficiency when biomass is burned in the gasifier,the temperature of the oxidation layer should be maintained at around 900℃,and the temperature of the reduction layer should be maintained at around 700℃.This provides a theoretical basis for the optimization design of the biomass gasifier.
