Abstract
In a pulse combustor in which a mixture of air and fuel gas is supplied into a combustion chamber and subjected to pulse combustion, a flame trap is provided at the inlet of the combustion chamber to prevent back fires. The flame trap is formed as follows: A first tape of metal foil such as stainless steel foil is welded to one side of a second tape of metal foil, for instance, by blazing in such a manner that the first tape is corrugated, thus forming cells between them. Next, the first and second tapes thus welded together are spirally wound and combined with each other, for instance, by blazing.
