Definitions

  • the invention which is in the technical field burners and in particular gas burners for appliance heating and / or domestic hot water production, relates more particularly to a burner support in which is integrated in particular the injection rail of combustible.
  • injection of gas in the burner arms is done from a ramp which carries a series of injectors and which is supplied with gas through an intake manifold.
  • This ramp is advantageously arranged horizontally in front of the device so as to be accessible and easily removable.
  • Each burner arm corresponding to each injector is fixed on a common support, and the boom injection must be precisely positioned by relation to the support so that the injectors are correctly centered on the mouths of the arms of burner.
  • the injection rail is therefore an element independent of the burner support to which it is connected by a set of pins or screws.
  • the Applicant has developed a burner support that incorporates the ramp fuel injection thus taking advantage of known techniques of manufacturing by extrusion, for obtain a monobloc assembly of lower cost price, which avoids the aforementioned drawbacks.
  • the subject of the invention is therefore a support for burner with integrated fuel rail according to which said support and at least one injection rail form a monobloc assembly obtained by extrusion, the ramp carrying the minus a series of gas injectors that are located plumb and at constant distance from at least one series circular openings provided on the support, and connecting bars connecting the support and the ramp.
  • the invention also relates to the method obtaining a burner support which consists in extruding simultaneously said support and at least one ramp injection and to machine opposite each other openings and holes in the support and the ramp respectively for the passage of the gas mixture and the mounting injectors.
  • Figures 1 and 2 views respectively in perspective and cross section of a burner support with integrated injection rail.
  • Figures 3 to 6 are cross-sectional views of variant embodiments.
  • the one-piece assembly shown in Figures 1 and 2 consists of a plate 1 having the general shape of an L and an injection ramp 2 which extends longitudinally between the two branches of the L and which is connected to the plate by connecting bars 3.
  • the ramp is open at its two ends, one being intended to be connected to one intake manifold, the other being closed by a plug.
  • the plate is the support of the burners not represented. It is pierced with a series of openings circular 4 directly above ramp 2. The latter is provided with threaded holes 5 exactly centered on the openings 4. On said orifices are screwed gas injectors 6.
  • bars of link 3 connect the ramp 2 to the L-shaped branch of the support 1 not provided with openings 4.
  • the assembly thus described is obtained by extrusion, for example of a metal or of composite materials followed by machining one in front of the other of the openings and orifices, respectively for the passage of the gas mixture and the mounting of the injectors. It is also possible to machine slots 7 favoring the positioning of the burners, a notch 8 for positioning the pilot and holes 9 which will serve to hold the burners, the flame detector, etc.
  • the ramp this time is attached by bars 3 to the L-shaped part of the support 1 which carries the openings 4.
  • the ramp 2 is housed inside a U-shaped support the two branches of which each carry a series openings 4.
  • the burner support is shaped of L and carries two rows of openings 4 opposite two injection manifolds 2 superimposed.
  • the support burner also has two rows of openings, but forms a closed shell with the injection ramps.
