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 1250-1400C. 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. ^ 1 tbl, 1 ex |
