摘　　要：介绍了木质粉尘燃爆的必要条件和充分条件,讨论了木质粉尘燃爆的浓度下限、点火温度和主要诱发源相应所需的有效点火能量。以木材加工企业实际发生的粉尘燃爆典型事故为案例,剖析了其产生的原因,系统地分析了木粉尘燃爆的防控部位,介绍了粉尘燃爆的防控技术与措施、燃爆危害的控制。The necessary and sufficient conditions for wood dust explosion are introduced in this paper.The lower explosive concentration limits of the dust cloud,and ignition temperature induced the dust to explosion,and required sufficient ignition energy related to some induce factors of the explosion are discussed.By taking several typical wood dust explosion accidents occurred in wood processing enterprises in China as examples,the causes and their induced factors are analyzed.To prevent the dust from explosion and reduce its damage,some technique,and measures of management are suggested.
