ABSTRACT:
A catalytic reactor, used as the ignition stage for a multi-stage combustor, is made by the following method. Alternate sides of a metal strip are first coated with a combustion catalyst, in such a manner that at any point on the strip, one side is coated and the other side is not coated. Then the strip is folded back and forth upon itself in a zigzag pattern, to produce the reactor. The strip has corrugations which keep adjacent portions of the strip spaced apart when the strip has been folded. The reactor made by this method has an extended useful life, in part because it does not become so hot that the catalyst becomes deactivated.
