Electroplasma Processing of Ash Waste From Incineration Into Glass-crystal Cast Materials
Year: 2025
Type: article
Abstract: The article examines the characteristics of ash waste obtained at incinerators (China) to establish the possibility of their use as a raw material in the production of glass-crystal casting by electroplasma method. Studies of the granulometric, mineralogical, and chemical composition of the raw materials were performed using dispersion-gravimetric, microscopic, spectral, and X-ray phase analyses. During the study, the true density, specific surface area, granulometric, chemical and mineralogical compositions of the raw materials and the stone castings obtained from it were established with the calculation of the modulus of acidity, which amounted to Mk = 2,73, which makes it possible to produce casting from a single-component charge (ash waste). In the process of electroplasmic melting of raw materials, a calcium-silicate stone casting was obtained, which is a crystallized melt of a given geometric shape made of quartz (SiO2) in its glass phase. The data obtained in the course of the conducted studies allow us to recommend electroplasma melting as a method of processing ash waste from incineration into a melt with low energy consumption (0,8–1,0 kWh/kg), and classify the produced product as a calcium-silicate glass-crystal casting.
