The invention relates to a device for introducing hot gas into a heating surface pipe of a waste heat boiler, comprising an outer pipe that is connected to the boiler wall, particularly to the bottom of the pipe. Said device also comprises an inner pipe or entry pipe, which has an admission section that is cylindrical or conically narrows, which is connected to the outer pipe via a rounded reversible cap while forming an entry opening for the hot gas, which is surrounded by the outer pipe at a distance and finally, which has a discharge section that is connected to the heating surface pipe. The device also comprises a coolant guiding pipe, which is placed between the outer pipe and the inner pipe and which extends into the proximity of the reversible cap, whereby the guiding pipe (4) is provided in the form of a force-transmitting component and is connected, in a removable or fixed manner, both to the inner pipe (5) as well as to the outer pipe (3) each time with at least three connecting ribs (7, 8), which are uniformly distributed over the periphery and which are provided for introducing or transferring forces.
L'invention concerne un dispositif permettant d'introduire des gaz chauds dans un tube à surfaces chaudes de chaudière de récupération, qui comprend un tube extérieur relié à la paroi de la chaudière, notamment avec le fond du tube, un tube intérieur et d'entrée entouré par un tube extérieur, à distance, qui se raccorde au tube extérieur par l'intermédiaire d'un capuchon réversible arrondi, de manière à former une ouverture d'entrée pour les gaz chauds et qui comporte une section d'afflux cylindrique ou se réduisant en cône et une section d'évacuation raccordée au tube à surfaces chaudes. Ledit dispositif comprend également un tube de guidage pour agent de refroidissement, monté entre le tube extérieur et le tube intérieur, qui s'étend jusqu'à proximité du capuchon réversible. Le tube de guidage (4) se présente sous forme d'élément transmetteur de forces et est relié de manière fixe ou amovible aussi bien avec le tube intérieur (5) qu'avec le tube extérieur (3), dans chaque cas avec au moins trois nervures de jonction (7, 8) réparties uniformément sur le pourtour, afin d'introduire et de faire passer les forces.
