Definitions

  • the invention relates to a burner head consisting of a row of slots and / or perforated metal plate on one side between the Rows of slots and / or holes with coolant flowing through them Pipe sections is connected.
  • Such a burner head is known from DE 87 03 407 U1.
  • the Pipe sections combined into a pipe coil and with the metal plate soldered.
  • the combustion products contain the lowest possible nitrogen oxide content.
  • the production the burner head is complicated, time-consuming and therefore very expensive.
  • the metal plate is one of these Burner head have already been designed as a composite plate, one middle layer of copper or aluminum on both sides with a stainless steel plating has been provided.
  • the stainless steel layer brings for the Metal plate good protection against corrosion and the middle copper layer has good thermal conductivity, so that the efficiency for cooling is improved.
  • the metal plate at least on the side facing the pipe sections with a stainless steel surface is provided, and that of copper or copper alloy existing pipe sections with at least one longitudinal weld Stainless steel surface of the metal plate are welded.
  • the welding process counteracts the conventional opinion a significant advance as the Disadvantages that occur for the function of the burner head are not negative Have an impact.
  • the burner head is particularly easy to manufacture by the fact that Longitudinal welds are designed as laser welds.
  • the heat transfer from the metal plate to the pipe sections can be reduced a further embodiment improve in that the metal plate in Area of the pipe sections to the convex outer curvature of the pipe sections have adapted, concavely curved receiving grooves, since the contact surfaces increase.
  • the metal plate in the area of the rows of slots and / or holes is also curved, then a defined deflection of the Metal plate reached in these areas and the metal plate breaks avoided these places.
  • the Curvatures of the metal plate in the area of the pipe sections and the rows of Slits and / or holes directed towards the same side of the metal plate are.
  • the metal plate itself can consist of ferritic stainless steel or as Connection plate made of copper with stainless steel plating.
  • the flat metal plate 10 according to FIG. 1 can consist of ferritic stainless steel and has spaced parallel rows of slots 11 and / or holes.
  • the remaining areas of the metal plate 10 are with pipe sections 20 welded, as the indicated longitudinal weld seams 30 show. It is a single longitudinal weld seam 30 is provided per tube section 20, which preferably is carried out as a laser weld seam.
  • the longitudinal weld seams 30 are made from the free side of the metal plate 10 so that in the Metal plate 10 diffusing copper is kept as low as possible.
  • the metal plate 10 can also be moved several times to one side, preferably the side free of pipe sections 20, be curved, and so between the rows of slots 11 and / or holes concave grooves 12 form for the pipe sections 20 to the contact surfaces between Metal plate 10 and pipe sections 20 to increase heat dissipation to improve.
  • the metal plate 10 can be a middle layer made of copper have and be provided on both sides with a stainless steel plating.
  • the mechanical connection can be made by two longitudinal weld seams 30 per pipe section 20 can be improved. Also in the area of the slots 11 and / or The metal plate 10 is arched to provide defined expansion movements obtained and to avoid breaks in the metal plate 10 at these points.
  • FIG. 3 shows that they are welded to the metal plate 10
  • Pipe sections 20 on the input and output sides via manifolds 40 and Connection piece 50 are combined to in all pipe sections 20th to achieve the same flow, pressure and heat dissipation properties.
  • the pipe sections 20 can be inserted into the connecting pieces 50 and / or be soldered or screwed to them.
  • the coolant system is connected.
