Features of Plasma-Thermal Melting of Ash and Slag from Incineration Plant1

The paper focuses on computational and experimental studies of processing ash residues from an incineration plant (IP). To prevent environmental contamination, it is required to melt IP ash and slag to obtain a useful product with neutral properties. Combined heating of ash and slag is proposed, and the time for melting of dispersed particles of silicon dioxide ( $$\alpha$$ quartz) under the action of arc plasma and resistive heating is calculated.
