Dust particles formed and propagated on the territory of industrial enterprises have certain physico-chemical properties. The traditional characteristic defining the properties of a dispersed (powder) system is its granulometric composition. Often, such properties of a dispersed material as (hygroscopicity, strength, porosity, abrasiveness, etc.) depend not only on the particle sizes in the dispersed material, but also on the shape of dust particles. Therefore, for a more complete analysis of the resulting emissions, it is necessary to know the shape of the solid particles contained in the gas-air mixture. To analyze the morphometric characteristics of solid particles, the transmission microscopy method was used, followed by the translation of the obtained raster photographs into binary format. The analysis of the obtained images was performed by Spotexplorer software. The data obtained after processing binary images were used to determine the morphological composition of solid particles.
