Definitions

  • the invention relates to a gas burner according to the preamble of the claim.
  • a two-part gas burner, in particular for a stool cooker, in which the outlet openings are arranged distributed over the entire surface of the upper part, has become known from DE-GM 85 13 182.
  • the outlet openings are designed as punched holes, to which there are only low precision requirements.
  • the aim of the invention is to propose a gas burner of the type mentioned at the outset, which is cheaper to manufacture and whose outlet openings meet high precision requirements.
  • the outlet openings or the nozzles being able to be arranged in the intended places with high accuracy, so that the intended center distances of the burner nozzles from each other can be adhered to very precisely.
  • the deep drawing of the upper part allows the nozzles to be arranged at the same height with high accuracy, as a result of which the entire surface of the upper side of the nozzle plate is stabilized.
  • the softer design of the lower part results in advantages with regard to the gas-tight connection of the two parts of the nozzle plate, since the lower part with its edges can be pressed very well onto the upper part, even with a limited deformation of the former. In this way, it is also possible to connect the two parts to one another by means of a collar flange, whereby a warping of the upper part can be avoided due to the softer design of the lower part.
  • the burner nozzles can be equipped with a cylindrical shaft, which is machined to a diameter that is suitable for the press.
  • the top-side receptacle is designed as a retracted collar with a cylindrical inner diameter, which has the associated press fit diameter.
  • the gas burner 1 is equipped with three parallel rows of nozzles 2, which are used in elevations 3.
  • This gas burner 1 has four openings 4 through which secondary air can flow from below to the flames.
  • channels 5 are provided in the area of the nozzles 2 arranged in rows, which are connected to one another and can be supplied by an essentially centrally arranged gas or mixture connection 6.
  • the metal gas burner 1 consists of an upper part 7, which is produced by deep drawing and provided with the elevations 3 and is designed to be very dimensionally stable, and a lower part 8, which has grooves 5 ′ for formation of the channels 5 and is of lower rigidity and dimensional stability than the upper part 7.
  • the nozzles 2 are pressed into the collar 11 of the outlet openings 12 of the elevations 3, the collar 11 receiving the tensions radially caused by the pressing in and thereby keeping the remaining part of the upper part 7 free of tension.
