Abstract (en)

Insulated combustion chamber walls are made of a honeycomb structure, shown typically as horizontal strips (4) linked by vertical bars (6) formed into cells by vertical strips (8), covered by a 1-2 mm thick metal skin. This skin is made of steel impervious to the combustion products. It is welded to the strips (4, 8).

Abstract (de)

Die Erfindung betrifft eine Wand eines Industrieofens mit Innenisolierung, Stahlwand und Außenversteifungen, bei der die Stahlwand als Wabenwand aus dünner Blechhaut (2) und einem aufgesetzten Gitter (Stäbe 4, 6) ausgebildet ist. Damit wird vermieden, daß bei kühler Witterung an der Ofenwand der Wassertaupunkt unterschritten wird und sich korrosive Flüssigkeiten bilden.
