The understanding of the influence of the interactions among lignocellulosic biomass components on pyrolysis and explosion can aid in preventing and controlling dust explosions. This study aimed to examine the pyrolysis behavior and explosion parameters of cellulose, hemicellulose, and lignin, the components of biomass dust, and their mixtures to expound the influence of their interaction through a comparative analysis of the experimental results and predicted values, using a thermogravimetric analyzer and 20 L spherical explosion vessel. The results show that a higher fraction of cellulose enhances the mixture’s weight loss peak intensity and explosion pressure. The increase in hemicellulose improves the shoulder peak intensity and the explosion rate of pressure rise. An increase of lignin leads to an increase in solid residue and a decrease in explosion pressure. The interaction among the components leads to the experimental thermogravimetric curve lagging the predicted curve obtained by the weighted average of the individual components. The explosion pressure of the mixture is mainly determined by the promotion and inhibition effect of cellulose and lignin, respectively, and the rate of pressure rise is mainly affected by hemicellulose content.

了解木质纤维素生物质组分之间的相互作用对热解和爆炸的影响有助于预防和控制粉尘爆炸。本研究旨在研究纤维素、半纤维素和木质素、生物质粉尘成分及其混合物的热解行为和爆炸参数，通过对实验结果和预测值的比较分析，利用热重分析阐述它们相互作用的影响。分析仪和 20 L 球形爆炸容器。结果表明，较高比例的纤维素提高了混合物的失重峰值强度和爆炸压力。半纤维素的增加提高了肩峰强度和压力上升的爆炸率。木质素的增加导致固体残留物的增加和爆炸压力的降低。组分之间的相互作用导致实验热重曲线滞后于通过单个组分的加权平均获得的预测曲线。混合物的爆炸压力主要取决于纤维素和木质素的促进作用和抑制作用，压力上升的速度主要受半纤维素含量的影响。
