Definitions

  • the present invention relates to a method of attaching an electrode to a Wall plate of a burner, wherein the wall plate has a bore, in which the ceramic insulating body of an electrode is arranged, whereupon by a pressing operation the metal material of the wall plate surrounding the ceramic body of the electrode in the direction the center of the bore is plastically deformed, so that the ceramic body through the Hole edge of the wall plate is held.
  • the present invention also relates to a burner electrode with a ceramic insulating body of the electrode in a bore receiving wall plate.
  • Such burner electrodes and method for fixing the electrodes in the wall panels of burners have been known in principle for a long time.

  • the term "wall panel” as used herein includes the term "retaining panel” and the Use of this term takes place here largely synonymous, even if as a rule separate, small retaining plates are meant, which are mounted on the Elektraden and in the assembled state of the burner form part of the wall of this burner, so that insofar as the term “wall plate” is correct.
  • One in a correspondingly larger opening a burner wall to be used retaining plate is in communication with the electrode and its Attachment therein easier to handle and therefore preferred.
  • the retaining plate relatively easily be tightly secured in the space provided for the wall panel, z. B. by screwing.
  • the connection between retaining plate and electrode is against it relatively expensive, since the electrode is under tension during operation or, in the Case of a monitoring electrode, must transport very small currents, so that by the holding plate guided electrode very well insulated from the holding plate itself have to be.
  • Electrode This is generally done by the ceramic insulator surrounding the electrode, wherein the unit of ceramic insulating body and the central metallic electrode element also collectively referred to as "electrode".
  • connection between the ceramic insulating body of the electrode and the retaining plate leaves Although mechanically relatively safe to produce by the usual pressing, but is this compound is generally not gastight.
  • modern burners will increasingly gas-tight combustors required and thus gas-tight connections between the ceramic body of the electrode and the associated holding plate. This is partly related to the fact that increasingly more burners with a fan operated, by which combustion air or a mixture of combustion air and burning gas is blown into the burner chamber, so that in the burner chamber a slight overpressure arises. This is to make the combustion more effective and with less Pollutant emissions occur.
  • the present invention has the object, a method for attaching burner electrodes in retaining plates or a corresponding, To provide burner plate provided with retaining plate, which is a gas-tight connection provide between holding plate and burner electrode.
  • this object is achieved in that before the pressing of the Holding plate or wall sheet an elastically or plastically deformable sealing ring between the hole edge of the wall plate (or holding plate) and the ceramic body of the Electrode is arranged.
  • the process for preparing such a compound is so designed that holding and positioning devices are provided, through which the between the edge of the hole and the ceramic body provided sealing ring during the pressing of the Holding plate remains at its intended position.
  • the sealing ring can also be self be configured in a corresponding manner, that he before connecting the retaining plate and Ceramic body either on the ceramic body or on the retaining plate or the hole edge firmly adheres to the retaining plate. Examples of this will be described later.
  • a Possibility for positioning or exact arrangement of the sealing ring lies therein, in the ceramic body in height of the mounting position of the retaining plate a circumferential groove to provide, in which a sealing ring is at least partially included. Of the Sealing ring can then not in the longitudinal direction on the generally cylindrical Slip ceramic body.
  • the sealing ring could also at the edge of the hole provided in the holding plate be attached, for. B. if in the opening edge of the holding plate a circumferential Well is provided, or if the sealing ring has a U- or L-shaped cross-section Has with one or two radially outwardly projecting legs, causing the sealing ring can be anchored to the opening edge of the retaining plate.
  • the pressing of the Metal of the retaining plate annular and substantially without interruption around the edge of the hole circulating in a substantially constant distance from the hole edge of the bore of the Holding plate takes place.
  • the pressure can also be interrupted and in particular simultaneously or successively over certain angle segments of 60 °, 90 ° or 120 ° take place, it can be between adjacent segments and short, unpressed webs remain.
  • this pressing takes place at a distance between 0.2 mm and 10 mm from Hole edge of the bore, wherein the width of the pressing line or a corresponding pressing tool preferably between 1 and 5 mm.
  • the pressing of the metal of the Holding plate preferably from both sides of the metal sheet ago and preferably in each case at the same distance to the edge of the hole and also in the same width and the same Cross-sectional shape of the pressing or of the pressing tool. That way expediently embossed annular grooves on both sides in the metal sheet, wherein a portion of the metal captured by the dies flows radially inwardly and therewith reduces the diameter of the bore receiving the ceramic body with the seal, in this way a firm engagement between retaining plate, seal and ceramic body manufacture.
  • Preßnuten be generated with trapezoidal cross-section.
  • a variant of the method is particularly preferred in which the pressing in such a way that the inner edges of the bore at the top and bottom of the Each sheet is pressed slightly more radially inward than the sheet material in one middle section in between, i. between the top and bottom of the sheet.
  • This causes a groove or circumferential recess to be effectively created in the hole edge in which the seal is securely held.
  • the seal in extends in the axial direction beyond the thickness of the retaining plate, come these protruding Edges of the mounting hole with the seal in a more or less linear Contact, which causes a high sealing pressure and thus the tightness of the Guaranteed connection in a special way.
  • the sealing ring is arranged such that between the Ceramic body of the electrode and the holding plate no direct contact exists.
  • the hole edge of the bore of the retaining plate engages only with the seal and the seal in turn on one side with this hole edge and on the other side engaged with the ceramic body.
  • sealing ring z As suitable materials for the sealing ring z. As PTFE, EPTM or silicone in question.
  • the sealing ring may also consist of a plastically deformable metal, such as. As copper or a copper alloy. such Metal gaskets are more suitable, especially when operating the burner on the holding plate and in particular in the region of the burner electrode on the holding plate higher Temperatures may arise to which the aforementioned elastomeric seals possibly would not withstand.
  • the seals for the connection according to the invention can have different cross sections to have. In question are both round and rectangular, as well as x-shaped cross-sectional shapes, without this list should be exhaustive.
  • FIG. 1 shows a burner in the form of a rectangular, here open on three sides illustrated box, which is tightly closed in the operation of the burner and only in the not shown here top an opening for the exit of exhaust gases accordingly has the arrow B shown there.
  • Fuel rods 21 which are hollow and which with their hollow interior with a fuel, concrete a fuel gas and an air supply in connection. This fuel gas and combustion air supply takes place along the arrow A, for example by the injector effect of supplied fuel gas, if necessary, with a blower, not shown here.
