Definitions

  • the invention relates to an electrode for use as an ionization electrode for flame monitoring or ignition electrode in a gas or oil burner according to the preamble of claim 1.
  • an ionization electrode With an ionization electrode, the presence of a flame in a burner supervised. In this case, a current flows at a monitoring distance between the electrode wire and a ground potential when the fuel / air mixture is ionized.
  • Ground potential in an atmospheric gas burner is usually the burner surface, in a fan burner for oil or gas usually the aperture for distribution the combustion air at the mixing device. From a firing machine will be evaluated the flame signals.
  • Known ionization electrodes consist of a solid wire which, in subregions, in particular for attachment, is enclosed by an electrically insulating body. Just like the required pair of ignition electrodes, which between its each other standing fire end forms a spark gap is the flame monitoring device with a holder on the aperture of a fan burner for oil or gas or on the Burner plate of an atmospheric gas burner attached.
  • ignition and ionization electrodes In addition to the temperature resistance, ignition and ionization electrodes must also have a have sufficient corrosion resistance to ensure safe burner operation over a to ensure a long period of time.
  • Metallic ignition electrodes are constantly subject to a certain burn-off, so that during maintenance possibly the spark gap or the electrode distance must be readjusted.
  • the problem is with the previously used Electrode wire the formation of insulating protective layers on the Surface, in particular by metal, chromium and aluminum oxides. That's what happens over time to a large drop in the possible ionization current. The ionization signal becomes weaker and there are calibrations based on combustion regulations necessary.
  • the invention is therefore the object of electrodes for ignition, flame monitoring and ionisationsstromteil to optimize gas and oil burners.
  • the electrode as lonisationselektrode for flame monitoring or ignition at a gas or oil burner is characterized in that at least that of the Flame applied area consists of an electrically conductive ceramic body.
  • the electrically conductive ceramic body is mounted in a Isolierkeramik redesign.
  • a bore in the center of the Isolierkeramik emotionss serve as a pin Steel wire and the electrically conductive ceramic body with an electrically conductive Glass melt fixed.
  • the electrically conductive ceramic body with an electrically conductive Glass melt fixed.
  • the steel wire protrudes on the opposite side from the Isolierkeramik redesign out.
  • the electrically conductive ceramic body may in a first embodiment, a rotationally symmetric Own form. This is favorable for use as ignition electrode.
  • the electrically conductive ceramic body can be flat be executed and have an angled end portion. This shows in the execution as ignition electrode preferably in the direction of spark gap and can optionally also pointed.
  • the surface running, electrically conductive ceramic body can from a composite of several ceramic, preferably sintered together Layers exist.
  • the Isolierkeramik redesign is attached to the outside of a retaining plate. Especially at one Zündelektrodencru is a Isolierkeramik redesign firmly connected to the support plate. In contrast, the adjacent, associated Isolierkeramik redesign is displaceable on the holding plate stored to adjust the electrode gap in the spark gap.
  • the electrical conductive ceramic body of an oxide ceramic in particular from the group of Silicon carbides.
  • the structure of an electrode for ignition, flame monitoring and ionisationsstrom miniaturized for gas and oil burners.
  • Compared to conventional Electrodes result in a significantly higher robustness, so that a safe burner operation over a long period of time.
  • burnup is only still minimal and when used as an ionization electrode for flame monitoring can no longer form insulating protective layers which the lonisationssignal weaken.
  • the electrode for use in flame monitoring consists of an ionization electrode 1 for ionisationsstromunk or is designed as ignition electrode 2. there the area of the electrode acted upon by the flame consists of an electric conductive ceramic body Each two ignition electrodes 2 are associated with each other and form a spark gap F between their ends.
  • the electrode is surrounded by a Isolierkeramik redesign 3 and thus fixed to a holder 4 for fixing the arrangement.
  • a steel wire is used as a pin 5 together with the electrically conductive ceramic body of the ionisation electrode 1 or the ignition electrode 2 is arranged in a bore in the center of the Isolierkeramik analysess 3 and fixed with an electrically conductive glass melt 6.
  • a Isolierkeramik redesign In a pair of ignition electrodes 2, a Isolierkeramik redesign 3 is fixed to the holding plate 4 connected. In contrast, the adjacent Isolierkeramik analyses 3 is slidable with a another plate 7 mounted on the support plate 4 to the electrode spacing and the spark gap F to adjust.
