PROCEDURE FOR THERMAL TREATMENT OF SOLID DOMESTIC AND INDUSTRIAL WASTE Russian patent published in 2011 - IPC C22B7/00 F27B17/00 

FIELD: metallurgy.

SUBSTANCE: wastes are treated in Vanyukov's furnace with slag melting, supplying charge and oxygen containing gas through tuyeres into slag melting. Charge is melted and slag is generated at temperature 1250-1400°C. The procedure is implemented in the furnace wherein height of tuyeres can be changed. With growth of the lowest working heat-producing capacity of charge height of axis of tuyeres arrangement from a bottom of the furnace is increased. Value of ratio of blast of oxygen containing gas (nm³/hour per 1 m² of cross section of a furnace) and the lowest working heat-producing capacity of charge (kJ/kg) is maintained within the ranges of 0.07-0.12 facilitating degree of carbon burning-out in charge to its residual content in slag at the level of 0.1-0.15%.

EFFECT: environmental safety of produced liquid and gaseous products of processing for their further utilisation, also maximal low combustible charge components under-burning for maximal utilisation of energy of processed waste.
