Abstract
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).
