Abstract

Oppfinnelsen vedrører en fremgangsmåte og en anordning for termisk behandling av ristaske (12) fra et søppelfor- brenningsanlegg med et forbrenningsrom (5) og en slaggsjakt. (7), hvor ristasken (12) føres fra søppelforbrenningsanleg- get inn i et rotasjonsrør (10), og der behandles termisk ved hjelp av et brensel (20) som omsettes med oksygen eller oksygenanriket luft (19). Oppfinnelsen er karakterisert ved at ristasken (12) via en tilførselsanordning (15) føres direkte fra slaggsjakten (7) inn i rotasjonsrøret (10), og avgassene (14) som oppstår ved den termiske behandling i rotasjonsrøret (10) tilbakeføres til søppelforbrenningsan- leggets forbrenningsrom (5) og føres sammen med avgassene (22) fra søppelforbrenningen.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method and apparatus for the thermal treatment of grate ash (12) from a garbage incinerator with a combustion chamber (5) and a slag chase. (7), wherein the grate ash (12) is fed from the garbage incinerator into a rotation tube (10), and thereafter thermally treated by a fuel (20) reacted with oxygen or oxygen-enriched air (19). The invention is characterized in that the grate (12) is fed directly from the slag shaft (7) into the rotary pipe (10) via a feed device (15), and the exhaust gases (14) arising from the thermal treatment in the rotary pipe (10) are returned to the garbage incinerator. combustion chamber (5) and fed together with the exhaust gases (22) from the waste incineration.
