Claims

[Scope of utility model registration request]

A combustor that injects the mixed gas formed in the vaporization mixing section into the flame hole on the open end side of the vaporization mixing section and combusts it, and a combustor that covers this combustor to form a combustion chamber and allows combustion gas from the combustor to pass through. Equipped with a combustion tube,
A closed combustion device characterized in that fins are provided on the outer surface of the combustion tube at a portion of the combustor that comes into contact with the flame.
