Definitions

  • the invention is directed to a dual-circuit burner with a burner body and with a central center burner and a second burner ring surrounding it at a distance, the center plug being assigned the spark plug and the thermocouple.
  • Such a dual-circuit burner is known, for example, from DE-41 25 308 or also from the burner designed by the applicant in 1986.
  • a compact ring burner with a side gas supply leading into a gas annulus the ring burner of which was held at a distance from the trough plate with a supporting body, was assigned a central center burner which was equipped with the spark plug and the thermocouple.
  • a similar construction is shown in DE-41 25 308 or EP-0 525 299.
  • the aim of the present invention is in particular to further develop and improve the in-house design in terms of gas supply, burner qualities and controllability, while at the same time being economical to produce.
  • this object is achieved according to the invention in that the burner body is designed to rest on a glass ceramic plate or to be fixed to a trough plate, the burner body having a central receptacle for the central burner and with gas passage chimneys distributed over the circumference equipped with an intermediate ring, leaving air ducts in the interior space of the burner are covered, the burner ring of the outer burner being mounted on the intermediate ring.
  • This design results in an extremely compact dual-circuit burner, which can be fixed to glass ceramic plates as well as the troughs of cookers, hot plates or the like. Due to the formation of gas pass-through chimneys which leave passage openings for the ambient air between them, it is possible to supply the central central burner with sufficient air, at the same time simple manufacture, whether as a cast part or as a forged part, is possible.

Abstract

La présente invention concerne un brûleur à deux circuits, comprenant un corps de brûleur, un brûleur central et un second anneau de brûleur, qui entoure à distance le brûleur central. La bougie d'allumage et le thermocouple sont associés au brûleur central. L'objectif de la présente invention est d'améliorer l'alimentation en gaz, la qualité du brûleur et la facilité de commande et de réglage, avec une production économique. A cette fin, le corps du brûleur (2) est conçu pour être soutenu sur une plaque vitrocéramique (6) ou pour être fixé sur une tôle en auge (6'). Ce corps de brûleur (2) présente un logement central (4), destiné au brûleur central (17), et est équipé de conduits de passage de gaz (8), répartis sur la périphérie, qui sont recouverts par un anneau intermédiaire (15) lorsque des orifices de passage d'air (16) dans l'espace intérieur du brûleur (1) sont laissés ouverts. L'anneau de brûleur (19) du brûleur externe repose sur l'anneau intermédiaire (15).
