Abstract

Oppfinnelsen angår en gjenvinningskjele for forbrenning av avlut. Den omfatter en ovn hvis fundament og vegger omfatter en rekke væskekjølte rør og hvis fundament (21) utgjør et samlingspunkt for uorganiske substanser i smeltet form, hvor luft og avlut føres inn i ovnen og forbrenningsgassene transporteres oppover i kjelen. Oppfinnelsen er hovedsakelig kjenntegnet ved at tverrsnittsarealet av ovnen ved et første lavere nivå (1) overstiger tverrsnittsarealet i ovnen i et annet nivå (2) høyere opp i ovnen.
