Abstract
A radiating tubes system of the double-pin type that is in the shape of a 'W' used in heating ovens, notably in continuous heating ovens for metallic bands, for providing the heat transfer between combustion bases released by a burner and the products to be heated. In the invention system, the burner is positioned in the lower branch of the tubes; the support device of the cold bend, in the upper portion of the tubes, is made in the form of a simple bearing base; the cold bend and the hot bend are connected to one another without a connecting-rod type intermediate part, and the intermediate bend and the lower tube are connected to one another with a settable play between these two elements.
