Environmentally Sound Technology for Processing Of Domestic Solid Waste and Other Toxic Waste in Sparged Molten Slag (ABSTRACT PAGE)

"An environmentally clean and virtually waste-less technology for treatment of domestic and industrial solid waste (HGIW) including other toxic chloride-containing materials has been developed and proven on a full scale by the Gintsvetmet Institute in cooperation with some other Russian organizations.The essence of the process is that the HGIW are decomposing in the liquid base in air-bed slag melted layer under the temperature of 1350-1400°C.HGIW is considered as fuel heat-producing energy of 1500-1800 kCal/kg with 51,7%.Processing of municipal and industrial solid waste in molten slag is carried out autogenously without additional fuel, the blowing is enriched by oxygen up to 50-70%.The complex makes it possible to treat the furnace charge without preliminary drying and sorting with big differences in chemical and morphological composition due to the versatile firing chamber.The proposed process resolves the acute and globally significant problem of dioxin formation.The purpose of the proposed technology is to ensure such destruction of the structural lattice that would guarantee irreversible transformation of the resultant substances to prevent formation of dioxins. It was established the required preconditions to achieve this purpose."
