Definitions
- the invention relates to a burner assembly according to the preamble of claim 1.
- Such a burner assembly is well known in the art.
- Gas burners in particular have a nozzle or burner plate made of metal.
- a gas flowing through the nozzles is burnt.
- flames extend from an upper side of the burner plate.
- gas would flow out through the nozzles. This can, for example, lead to the formation of an explosive gas / air mixture in a closed space.
- a monitoring device is provided on the burner plate for monitoring the extinction of the flames extending from the burner plate.
- the metallic burner plate serves as a cathode.
- an anode is provided in the area of the flames.
- the extinguishment of a flame can be detected by means of a significant change in the electrical conductivity between the cathode and the anode and, as a result, a safety shut-off valve activated in a gas supply line can be closed.
- a safety shut-off valve activated in a gas supply line can be closed.
- the object of the invention is to eliminate the disadvantages of the prior art.
- a burner arrangement is to be specified, which enables low-emission combustion and at the same time an undesired escape of unburned fuel is quickly and reliably recognizable.
- the burner plate made of a non-metallic material and the cathode is arranged as a separately formed component in the region of the top of the burner plate.
- the proposed burner arrangement enables a fast and Reliable detection of the extinguishment of a flame, a faulty ignition or the like .
- the proposed burner assembly is suitable both for the realization of surface and volume burners. Such burners allow a particularly clean combustion of fuel.
- fuel is understood in particular to mean gaseous fuels, for example combustible gases, vaporized liquid fuels, for example mixtures of vaporized oil and air, alcohol / air mixtures and the like.
- a volume burner body with a combustion-permitting communicating pore space opposite the top is arranged.
- the provision of such a volume burner body makes it possible to produce a volume burner in a simple and cost-effective manner.
- the combustion of the fuel takes place substantially within the volume burner body.
- a slot having a predetermined width can be provided between the upper side and an underside of the volume burner body.
- Slit is suitably 0.5 to 15 mm, preferably 1 to 5 mm.
- the provision of the proposed slot simplifies the ignition.
- the volume burner body and / or the burner plate is / are made of a ceramic material. It may be a porous ceramic, a perforated plate, a ceramic foam or the like.
- the cathode is arranged in the slot. For example, it can rest on the top. However, it is particularly advantageous that see that the cathode is received in a recess opening towards the top of the burner plate. In this case, an undesirably high heating of the cathode during operation of the burner assembly is avoided. This allows a particularly accurate detection of a fault condition.
- the apertures provided in the burner plate open into the recess.
- the cathode accommodated in the recess is surrounded by still unburned gas and thus cooled.
- the recess is preferably made so deep that the cathode is completely contained therein, d. H. the cathode does not protrude from the recess above the top, especially not in the region of the firing zone.
- the cathode extends from the recess to a further underside of the burner plate opposite the top side. This allows a simple way of dissipating the heat from the cathode to the opposite cooling another bottom.
- the cathode is received in a recess opening towards the underside of the volume burner body.
- the cathode z. T In one at the top of the burner plate and in one at the bottom of the volume burner body is partially received in each case.
- the recess formed corresponding to the shape of the cathode is. This can be avoided in a simple and cost-effective manner unwanted strong heating of the cathode.
- the cathode can be formed from a perforated plate or, preferably spiral or meandering, bent wire. It is expediently made of a temperature-resistant metal.
- the proposed burner arrangement is expediently used in particular in gas burners.
- FIG. 1 is a perspective view of a first burner assembly
- FIG. 1 is a sectional view of FIG. 1,
- FIG. 3 is a perspective view of a second burner assembly
- FIG. 4 is a detailed view of the area A in Fig. 3,
- FIG. 5 is a perspective view of a first cathode
- FIG. 6 is a perspective view of a second cathode
- Fig. 7 is a perspective view of a third cathode
- Fig. 8 is a perspective view of a fourth cathode.
- Figs. 1 and 2 show views of a first burner assembly. It is a surface burner.
- prepared burner plate 1 has the shape of a cylindrical disc.
- the burner plate 1 is provided with a plurality of axially extending apertures 2 for passing, z.
- Reference numeral 3 designates flames extending from an upper side 4 of the burner plate 1.
- a diameter of the apertures 2 is chosen so that it is impossible to penetrate the flames 3, ie the formation of a flame 3 within the apertures 2.
- a cathode 5 made of a temperature-resistant metal is received in a recess 6 which is of corresponding design and opens towards the upper side 4.
- the recess 6 is formed so deep that in it, for example, in the form of a curved wire running, cathode 5 is completely absorbed. Ie. the cathode 5 does not project beyond the top 4.
- the openings 2 may extend into the recess 6.
- the recess 6 can be made either by burning the burner plate 1 forming ceramic by milling, grinding or the like .. Preferably, however, the recess 6 is already produced prior to the burning of the burner plate 1 by a corresponding shaping or processing of the green body.
- the reference numeral 7 designates an anode, which protrudes in approximately opposite arrangement to the cathode 5 into the area of the flames 3.
- FIGS. 3 and 4 show a second burner arrangement.
- a volume burner element 9 produced in the form of a cylindrical disk is provided above the upper side 4 of the burner plate 1.
- a slot 11 formed between the top 4 and a volume burner bottom 10 has a width in the range of 1 to 5 mm.
- the volume burner element 9 is expediently made of a porous material, for example a porous ceramic, a ceramic foam, a metal mesh or the like. , produced .
- the volume burner element 9 has a further opening 12, through which the anode 7 is guided to near the top 4 of the burner plate 1.
- the gas is ignited by means of an ignition device (not shown here).
- an ignition device (not shown here).
- a significant change in the electrical conductivity is measured between the cathode 5 and the anode 7 by means of a measuring device (not shown here).
- This change indicates the presence of the flames 3. If the flames 3, for example as a result of faulty ignition or a gust of wind, do not arise or go out, this is detected by the non-adjusting increased conductivity between the cathode 5 and the anode 7.
- a safety shut-off valve turned on in a gas supply line may be automatically closed.
- the cathode 5 is inserted into the recess 6 which opens toward the upper side 4 of the burner plate 1.
- the flames 3 only extend from the upper side 4 of the burner plate 1, ie the cathode 5 is not located within the flames 3.
- the cathode 5 can penetrate into the recess 6 extending openings 2 are lapped with gas and thus cooled or kept in a predetermined temperature range.
- the cathode 5 is made of a bent wire. It has in each case at least one end 5a for passing up to the burner plate underside 8. As can be seen from FIGS. 5 to 7, the wire can be bent in a meandering or also a spiral shape.
- the cathode 5 shown in FIG. 8 consists of a perforated plate with a heat dissipating and connecting element 13 extending therefrom. LIST OF REFERENCE NUMBERS
