Definitions

  • the invention relates to a burner arrangement as defined in the preamble of claim 1 .
  • Such a burner arrangement is generally known in accordance with the state of technology.
  • gas burners are equipped with a nozzle or burner plate made of metal.
  • a gas flowing through the nozzles is burnt.
  • flames extend from a top side of the burner plate.
  • gas would escape through the nozzles.
  • a monitoring unit is provided on the burner plate to monitor the extinguishment of the flames extending from the burner plate.
  • the metallic burner plate serves as the cathode.
  • An anode is provided above the cathode in the area of the flames.
  • the extinguishment of a flame can be detected based on a significant change in the electrical conductivity between the cathode and the anode and, as a result of this, a safety shutoff valve installed in a gas feeder line can be closed.
  • gas burners which burn the gas by creating an open flame do not make optimal combustion possible, among other things.
  • gas pore burner From DE 43 22 109 A1 a so-called gas pore burner is known.
  • the gas is burned in a volume burner element made of porous ceramic.
  • the suggested gas pore burner makes possible particularly clean combustion. Due to the provision of a volume burner element, an undesirable breakdown of the combustion reaction will almost never occur during operation.
  • the object of the invention is to eliminate the disadvantages as per the state of technology.
  • a burner arrangement is to be specified which makes low-pollution combustion possible and, at the same time, the quick and reliable detection of the undesired escape of unburnt fuel.
  • the burner plate is made from a non-metallic material and the cathode is located as a separately formed component in the area of the top side of the burner plate.
  • the suggested burner arrangement makes possible quick and reliable detection of the extinguishment of a flame, a faulty ignition or similar.
  • the suggested burner arrangement is suitable for the implementation of both surface and volume burners. Such burners make particularly clean fuel combustion possible.
  • fuel is understood to mean in particular gaseous fuels, for example combustible gases, vaporized liquid fuels, for example mixtures of vaporized oil and air, alcohol/air mixtures and similar.
  • a volume burner body with a combustion-enabling, communicating pore area is located opposite the top side.
  • the provision of such a volume burner body makes possible a simple and inexpensive way to make a volume burner.
  • the combustion of the fuel occurs essentially within the volume burner body.
  • a slit with a specified width can be provided between the top side and a bottom side of the volume burner body.
  • the width of the slit is usefully 0.5 to 15 mm, preferably 1 to 5 mm.
  • the provision of the suggested slit simplifies ignition.
  • the volume burner body and/or the burner plate is/are made of a ceramic material.
  • this can be porous ceramic, a perforated plate, a ceramic foam or similar.
  • the cathode is located in the slit. It can lie on the top side, for example. But it is considered as particularly advantageous when the cathode is contained in a recess which opens towards the top side of the burner plate. In this case, an undesirable strong heating up of the cathode during the operation of the burner arrangement is avoided. This makes possible a particularly precise detection of a malfunction.
  • the recess is preferably designed deep enough so that the cathode can be completely contained in it. In other words, the cathode does not protrude out of the recess over the top side, in particular, not in the area of the combustion zone.
  • the cathode extends from the recess to a further bottom side of the burner plate opposite the top side. This makes possible a simple way to conduct off the heat from the cathode to the opposite further bottom side which is cool.
  • the cathode is contained in a recess which opens towards the bottom side of the volume burner body. Besides this, it is also conceivable that to some extent the cathode is partially contained in a [lacuna] on the top side of the burner plate as well as in a [lacuna] on the bottom side of the volume burner body.
  • the recess is formed corresponding to the shape of the cathode. This provides a simple and inexpensive way to prevent undesired strong heating up of the cathode.
  • the cathode can be formed from a perforated plate or, preferably a spiral or meandering-shaped, bent wire. It is usefully made of a temperature-resistant metal.
  • the suggested burner arrangement is usefully used with gas burners in particular.
  • FIG. 1 A perspective view of a first burner arrangement
  • FIG. 2 A sectional view as per FIG. 1 ,
  • FIG. 3 A perspective view of a second burner arrangement
  • FIG. 4 A detail view of area A in FIG. 3 .
  • FIG. 5 A perspective view of a first cathode
  • FIG. 6 A perspective view of a second cathode
  • FIG. 7 A perspective view of a third cathode
  • FIG. 8 A perspective view of a fourth cathode.
  • FIG. 1 and 2 show views of a first burner arrangement.
  • the burner is a surface burner.
  • a burner plate 1 made of a ceramic material, for example Al 2 O 3 , ZrO 2 or similar, has the form of a cylindrical disk.
  • Burner plate 1 is provided with a plurality of axially running breakthroughs 2 to conduct a gaseous fuel, for example.
  • Reference designator 3 denotes flames extending from a top side 4 of the burner plate 1 .
  • a diameter of the breakthroughs 2 is selected in such a manner that the spread of the flames 3 , in other words the formation of a flame 3 within the breakthroughs 2 , is impossible.
  • a cathode 5 made of a temperature-resistant metal is contained in a correspondingly formed recess 6 which opens towards the top side 4 .
  • the depth of the recess 6 is such that the recess can completely hold the cathode 5 which is designed, for example, in the shape of a bent wire. In other words, the cathode 5 does not protrude over the top side 4 .
  • the breakthroughs 2 can extend into the recess 6 .
  • the recess 6 can be made either by milling, grinding or similar after the firing of the ceramic which forms the burner plate 1 . But preferably the recess 6 will already be made before the firing of the burner plate 1 by appropriate shaping or processing of the green body.
  • Reference designator 7 denotes an anode which protrudes into the area of the flames 3 in the approximate opposite arrangement to cathode 5 .
  • FIG. 1 particularly shows, the ends 5 a of the cathode 5 are led through and out of the burner plate 1 via a bottom side of burner plate 8 .
  • FIG. 3 and 4 show a second burner arrangement.
  • a volume burner element 9 made in the shape of a cylindrical disk is provided above the top side 4 of the burner plate 1 .
  • a slit 11 formed between the top side 4 and a volume burner bottom side 10 has a width in the range of 1 to 5 mm.
  • the volume burner element 9 is usefully made of a porous material, for example a porous ceramic, a ceramic foam, metal braiding or similar.
  • the volume burner element 9 has a further breakthrough 12 through which the anode 7 is led up to the vicinity of the top side 4 of the burner plate 1 .
  • the gas is ignited with a ignition device (not shown here). Because of this, the flames 3 extend from the top side 4 to the burner plate 1 . Due to the formation of the flames 3 , a significant change in the electrical conductivity is measured between the cathode 5 and the anode 7 via a measuring device (not shown here). This change shows the existence of the flames 3 . If the flames 3 do not occur, due to a faulty ignition or gust of wind for example, or are extinguished, this is detected by the lack of increased conductivity between cathode 5 and anode 7 . For example, a safety shutoff valve installed in a gas feeder line can be automatically closed.
  • the cathode 5 is placed in the recess 6 which opens towards the top side 4 of the burner plate 1 .
  • the flames 3 extend first from the top side 4 of the burner plate 1 .
  • the cathode 5 is not located within the flames 3 .
  • the cathode 5 can be surrounded with gas through the breakthroughs 2 extending into the recess 6 and thus be cooled or maintained within a specified temperature range.
  • FIG. 5 to 8 show possible embodiments of the cathode 5 .
  • the cathode 5 is made from a bent wire. It has at least one end 5 a each for leading through up to the bottom side of the burner plate 8 .
  • the wire can be bent either meandering-shaped or also like a spiral.
  • the cathode 5 shown in FIG. 8 consists of a perforated plate with a heat dissipating and connection element 13 extending therefrom.
