ABSTRACT:
There is provided an improved honeycomb type gas conduit characterized by alternating noncorrugated aluminized ferrous metal foil and corrugated metal foil sheets in contact with each other at the apices or crests of the corrugation. The conduit has an inlet and an outlet for the gas and the honeycomb structure from 20 to 200 cells per square inch. The axes of the cells are parallel throughout their length. A hardened ceramic lip is provided at the leading edge of the cells, and preferably at the leading and trailing edges. When hardened by curing, e.g., with high temperature, the ceramic applied as a slip, forms fillets at the nips between the corrugations and the flat foil sheets, and cements the two together very tightly.
