FIELD: chemistry.
SUBSTANCE: in the method for thermal recycling, solid household wastes are fed together with fuel and a fluxing agent into a combustion chamber with a constant oxygen-containing draught. Processing products in form of molten slag are fed into a slag bath under gravity by slanting the bottom of the combustion chamber towards the slag bath. Exhaust gases are bubbled into the slag bath by passing them at least once through the molten slag with a constant oxygen-containing draught over and under the molten slag. Exhaust gases from the combustion chamber undergo after-burning by feeding molten slag and the exhaust gases into an exhaust-heat boiler with an oxygen-containing draught over the molten slag in the presence of a fluxing agent. The apparatus for realising the method is described.
EFFECT: reduced content of harmful components in exhaust gases and molten slag.
