摘要： The invention relates to a process and an apparatus intended to effect the combustion of a mixture of air and liquid or gaseous fuel, wherein the injection of the fuel is staged without that of the air for combustion being staged. According to the invention, in addition to the primary means (20, 34) for injecting fuel into the passage (10, 14) supplying air to the burner, secondary injection means (24) mounted inside said passage are provided and comprise a main part (24a) which is extended by a terminal part (24b) bent in such a manner that the end of said terminal part is situated downstream of the end of the primary means (20, 34) and at a distance from the axis (2) of said passage which is greater than the minimum section of the latter. The invention is applicable both to so-called parallel air admission burners and to burners having swirl vanes.

摘要： A device for mounting burners inside a duct for gas and comprising at least one fuel injection pipe having a nose disposed in the head of said burner on an axis parallel to the axis of the duct. The injection pipe is situated inside a sheath secured to the burner head for feeding it with air from outside the duct and disposed transversely relative to the axis of the duct, and the nose of the injection pipe, situated at the end of a bent portion of the pipe, is movable along the axis relative to a guide orifice secured to the burner head, from which it is suitable for being disengaged by the injection pipe being moved inside the sheath from outside the duct, thereby making it possible, from outside the duct, to extract the injection pipe completely to the outside of the duct.
