Abstract
The determination of the dispersed composition of the solid ingredients’ particles in the work area air and evaluation of the dust concentration’s meanings at non-stationary sources of emissions into the atmosphere of an electric smelting shop
Incoming article date: 26.10.2023At the present stage of increasing competition, the increased level of threats to the economic condition of business entities in any sector of the economy requires special attention. Enterprises of this industry annually emit aerosols of various composition and origin into the atmosphere: iron, vanadium, aluminum oxides, manganese oxides and other heavy metals. One of the components of safety is environmental safety and ensuring safe working conditions. The chemical composition of the dust-gas-air mixture of metallurgy enterprises is considered in the article, and the dispersed composition of aerosol emissions is determined. The data of the results of microscopic analysis of the fractional composition of dust based on the data of integral dependences of the density of distribution by equivalent sizes (diameters) D for the ingredients accepted for the study allowed us to determine the average median values of equivalent dust diameters.
