Abstract

This study evaluated the explosive hazardous properties and the likelihood of dust explosion in four types of waste dust collected from industrial sites. Waste dust samples were collected from the cement manufacturing industry, aluminum, and aluminum alloy ingot manufacturing industry, and copper alloy and non-ferrous product manufacturing industry. We evaluated whether the dust waste contained explosive substances using a standard method. Additionally, the factors that may affect the dust explosion, the presence of combustible substances, average particle size, particle size distribution, particle shape, moisture content, and calorific value were also evaluated. It was confirmed that the likelihood of dust explosion of dust waste generated in the aluminum and aluminum alloy manufacturing industry is higher than that of dust waste generated in other industries.
