Claims (9)
1. Schaktugn för smältning av mineralier vid framställning av mineralull, vilken ugn är tvädelad, varvid den innehäller en Övre och en nedre del, varvid den övre delen försetts med en insatsnings-anordning för de mineralier som skall smältas och för koks och den undre delen, som fungerar som förbränningszon, har vid bottenomrädet försetts med luftkanaler för inmatning av förbränningsluft, k ä n-netecknad av en avsmalning (12, 19) mellan de bäda schakt-ugnsdelarna (10, 13; 11, 35) och att under denna avsmalning anpas-sats avledningsrör (22) för vid förbränning uppkommande kolmonoxid (CO) och/eller svavelväte (i^S) innehällande rökgaser, att dessa avledningsrör förenats med en sekundär förbränningskammare (23), och att den sekundära förbränningskammaren försetts med ätminstone ett skilt inmatningsrör (21) för förbränningsluften, och att mellan den sekundära förbränningskammaren (23) och den övre delen av schaktugnen (11, 35) anpassats ett äterloppsrör (30) för ätminstone den del av rökgaser, som uppstär vid den sekundära förbränningen.
2. Schaktugn enligt patentkravet l,kännetecknad av att den sekundära förbränningsugnen (23) anpassats pä sädant ställe ovanom luftkanalerna där bildning av kolmonoxid (CO) ätminstone huvudsakligen upphört och där temperaturen alltid är sä hög, att blandningen av avledd rökgas och skild förbränningsluft är själv-brinnande.
3. Schaktugn enligt patentkravet 1 eller 2,känneteck- n a d av att tili kanalen längs vilken rökgaserna avleds anpassats
