Abstract
In a burner of the double cone type, at least one relief slit (30) is arranged in the front plate (18) locally between the regions having different axial expansions. The flexible connection remaining between the two outlet regions may be made integrally within the same casting or via a further welded-on part. Excessive thermal stresses are advantageously avoided thereby.
