Description

Anordning for gassoppsamling i elektriske
smelteovner.
Oppfinnelsen er et tillegg til norsk patent nr. 1 13. 507. Hovedpatentet beskriver
en anordning for gassoppsamling i elektriske smelteovner som er utstyrt med et hvelv hvis topp dekker ovnsarealet helt eller delvis, idet hvelvets sidevegger eller seksjoner av disse er erstattet med en strøm av oksygenfrie reakspnsgas ser, respektive reaksjonsgasser med redusert oksygeninnhold. Det således dannede gass-slør hindrer ovnsgassen i å trenge ut i ovnshallen, samtidig som det er mulig å stake i chargen uten å avbryte gassoppsamlingen. Gass-sløret som jo er gjennom-siktig, muliggjør også observasjon av forholdene i ovnen uten at man må benytte inspeksjonsluker eller lignende anordninger.
Det er kjent fra "Archiv flir das Eisen hutten wesen" 11 /l960 at man kan anvende luftslør som vegger i varmeholds- og fremskyvningsovner. Disse ovner produser-er imidlertid ikke gass i nevneverdig grad, og forholdene er derfor helt forskjellige fra elektriske reduksjonsovner hvor det er en sterk og ujevn gassutvikling. Det har imidlertid vist seg mulig at man ved anordningen ifølge hovedpatentet kan holde gassen tilbake, selv under såkalte "blåsinger", hvor gassen unnviker eksplosjons-artet og under stort trykk.
På den tid da hovedkravet ble innsendt var man av den oppfatning at de gassarter som skulle benyttes i gass-sløret ikke måtte inneholde vesentlige mengder oksygen, da oksygenet ville forårsake en forbrenning av de sterkt CO-holdige ovnsgasser, som befant seg innenfor gass-sløret. Man antok at forbrenningen og den dermed følgende varmeutvikling ville bli så sterk at ovnen og ovnsutstyret ville bli skadet. Hovedkravet spesifiserer derfor at de gassarter som skulle anvendes i gass-sløret måtte være oksygenfrie, respektive bare inneholde mindre mengder oksygen.
Patentsøkeren har fortsatt sine forsøk med gassoppsamling ved hjelp av gass-slør, og har overraskende funnet at det er mulig å anvende slør som utgjøres av forbrenningsgasser som er sterkt fortynnet med luft, og at dette kan gjøres uten at ovnsgassen forbrennes i slik grad at det er skadelig for ovnen og ovnsutstyret. Ved frem-gangsmåten ifølge oppfinnelsen blir gassene som utvikles i smelteovnen forbrent i pipen og under forbrenningen suges det inn store mengder falsk luft. Forbrennings-gassene blir således sterkt fortynnet med luft og volumet økes dermed betraktelig. Blandingen av luft og forbrenningsgasser suges bort fra pipen og returneres til gass-sløret.. Gassene kan om ønskes renses før returneringen til sløret, men dette er ikke nødvendig. Den gassmengde som brukes i gass-sløret er betraktelig stør-re enn den mengde gass som produseres i ovnen, og dette har overraskende nok resultert i en "røkfri" ovn. All gass som produseres i ovnen forbrennes, og det har endog vært nødvendig å tilføre gass fra andre ovner i smelteverket, f. eks. fra helt lukkede ovner, for å få nok forbrenningsgass til gass-sløret. Den gass som brukes i gass-sløret er altså så sterkt fortynnet med så store mengder luft at man heller kan snakke om luft som inneholder forbrenningsgas ser.

Claims (1)

  1. Anordning for gassoppsamling i elektriske.smelteovner som beskrevet i norsk patent nr. 113.50 7^ karakterisert ved at gas strømmene utgjøres av den gas s-luftblanding som oppstår når ovnsgassene forbrennes med stort overskudd av luft.
