Abstract (en)
[origin: EP0383687A1] System of radiant tubes of the type of double-pin or W type used in heating furnaces, in particular in furnaces for heating metal bands passing continuously, for carrying out the heat transfer between the combustion gases emitted by a burner and the products to be heated, characterised in that - the burner (14) is positioned in the cold part of the tubes (10), that is to say in the lower branch (16) of said tubes; - the support device of the cold bend (22) in the upper part of the tubes is made in the form of a simple support (26, 28); - the cold bend (22) and the hot bend (18) are interconnected without an intermediate welded piece, and - the intermediate bend (20) and the lower tube (16) are interconnected with adjustable play between these two elements. <IMAGE>
