Energy Efficient Technology of Solid Domestic Waste Recycling in Shaft Furnaces of Cupola Type

Abstract

The technology of high-temperature pyrolysis (over 850°C) performed in an energy plant based on a shaft melting unit is one of the most efficient ways of solid domestic waste neutralization and recycling. It includes preliminary preparation in the extruder, high-temperature pyrolysis under the conditions of shaft furnace smelting with addition of solid fuel, cleaning and use of pyrolysis gases as a fuel in the boiler. The generating solid waste represents safe mineral components.
