Physico-Chemical Processes of Spherical particle Production Using Low-Temperature Plasma
Abstract
The paper presents the theoretical and experimental results on silicate melts produced by the low-temperature plasma used for the spherical particle production. The experiments allow detecting physic-chemical processes observed during the production of silicate melts from the bottom ash waste. The melting curves are obtained for the bottom ash waste model system and that one based on its actual chemical composition. It is shown that the silicate melt is obtained due to the low-temperature plasma with heating rate of over 1000 °С per second and characterized by the concurrent melting of all phases, in contrast to the processes occurring at conventional heating rates of 0,5-1 °С per second.
