Incinerator for thermal cleaning of ash and slag waste

Journal of Physics: Conference Series, 2020
Abstract The research of remelting ash of incineration waste was described. The chemical composition of ash and slag waste in the process of thermal neutralization of municipal solid waste was revealed. To determine the chemical and phase composition of the ash at a temperature of 1700K, thermodynamic calculations were performed.
