To assess the chemical composition and parametric characteristics of electric arc furnace dust particles
Incoming article date: 03.11.2024Ferrous metallurgy enterprises emit a significant amount of fine dust into the atmosphere every year. The article presents the results of a study performed to determine the dispersed composition of the dust of the ingredients in the emissions of the furnaces of the chipboard steelmaking workshop. The combined use of energy dispersive spectroscopy (EDS) and energy dispersive X-ray spectroscopy of the analysis made it possible to obtain the fractional composition of the ingredients, the values of equivalent dust particle sizes and the integral dependences of the distribution density for equivalent sizes (diameters) were obtained D ingredients containing dust from chipboard furnaces in the samples. Based on the conducted research, it was concluded that it is possible to use certain types of dust collectors in dedusting systems to achieve an acceptable value of their effectiveness to improve the environmental safety of the steelmaking shop.
