摘要

木尘由木材加工过程中产生的木材细颗粒组成。它被认为是爆炸性的，尤其是当它产生尘埃云时。在尘埃-空气云中启动燃烧过程会将这一过程传播到整个体积。本文通过实验研究了硬木的种类对燃烧参数的影响。进行了一项实验研究，以确定三种类型的硬木粉尘的着火敏感性、着火行为和爆炸特性的演变。为了确定火灾条件下的灰尘行为，使用了锥形量热计。使用20 L球形容器，并在改进的哈特曼管MINOR II装置上测试了最小点火能量。研究表明，颗粒大小对爆炸参数有很大影响，而对于可燃性参数，这种影响并不那么明显。

Flammability and explosion characteristics of hardwood dust

Wood dust consists of the fine particles of wood that are produced when wood is processed. It is considered explosive, especially if it produces a dust cloud. Initiating the combustion process inside the dust–air cloud spreads this process throughout the entire volume. In this article, experiment was carried out to study the influence of type of hardwood on combustion parameters. An experimental investigation was carried out to determine the evolution of the ignition sensitivity, fire behaviour and explosion characteristics of three types of hardwood dust. To determine dust behaviour under fire conditions, a cone calorimeter was used. Explosion characteristics were tested with the use of a 20 L spherical vessel and minimum ignition energy tested on MINOR II Apparatus, which is a modified Hartmann’s Tube. Studies have shown a large effect of particle size on explosion parameters, while for flammability parameters the effect is not so noticeable.

期刊介绍： The Journal of Fire Sciences is a leading journal for the reporting of significant fundamental and applied research that brings understanding of fire chemistry and fire physics to fire safety. Its content is aimed toward the prevention and mitigation of the adverse effects of fires involving combustible materials, as well as development of new tools to better address fire safety needs. The Journal of Fire Sciences covers experimental or theoretical studies of fire initiation and growth, flame retardant chemistry, fire physics relative to material behavior, fire containment, fire threat to people and the environment and fire safety engineering. This journal is a member of the Committee on Publication Ethics (COPE).
