Abstract

Four comprenant un tube à feu et une chambre finale de combustion située axialement en aval de celui-ci, et muni d'un passage rétréci entre le tube à feu et la chambre de combustion finale. Le passage est situé dans une paroi de séparation définissant l'extrémité interne du tube à feu et un certain nombre de gorges ouvertes vers le tube à feu et dirigées trangentiellement par rapport à un cercle imaginaire, inscrit à l'intérieur dudit passage, sont formées dans la surface inclinée de ladite paroi. Application notamment aux chaudières à vapeur.Furnace comprising a fire tube and a final combustion chamber located axially downstream of the latter, and provided with a narrow passage between the fire tube and the final combustion chamber. The passage is located in a partition wall defining the inner end of the fire tube and a number of grooves open towards the fire tube and directed trangentially with respect to an imaginary circle, inscribed inside said passage, are formed. in the inclined surface of said wall. Application in particular to steam boilers.
