Definitions

  • the invention relates to a surface burner according to the preamble of claim 1 and a method for monitoring flame formation in a surface burner according to claim 18.
  • Area burners are usually operated with gas, such as natural gas or biogas. Possible fuels but also liquid fuels such as fuel oil, ethanol or methanol into consideration.
  • gaseous fuel-air mixture is usually generated in a mixing chamber and passed through a perforated metal distributor plate to the burner surface, which may have a fiber knit, for example of metal fibers or a ceramic tile.
  • the distributor plate serves for uniform distribution of the fuel-air mixture, which is burned at the side facing away from the distributor plate side of the fiber knitted fabric. On the fiber knit or on the burner surface so there is a flame area.
  • fiber knit is here representative of any known type of flat fiber system or thread system and thus includes fiber materials or thread materials produced by knitting, knitting, crocheting, weaving, felting, walking and / or pressing. Because of the statistical distribution of the fibers, threads, meshes and / or pores, their geometry can not be produced reproducibly with the same precision as in other machining processes (for example, machining).
  • Such surface burners are used in particular in heaters and water heaters.
  • a monitoring electrode for example an ionization electrode
  • a monitoring of the Combustion quality and in particular the level of oxygen content in the combustion mixture Due to a high temperature of the flame, the combustion mixture is ionized and has a measurable conductivity, which is measured by means of the monitoring electrode and provided to a control unit. This is a regulation of the composition of the fuel-air mixture.
  • any clearly defined and locally reproducible flames can be generated in the case of surface burners with fiber knits (for example in the region of the monitoring electrode).
  • a fiber knit is not completely uniform. Due to the non-reproducible knit geometry, there are no flames clearly defined in terms of flame geometry (flame pattern, length, shape, etc.) or combustion parameters (flame temperature, burnout rate, flame lift off or flame on the burner surface, etc.). Therefore, these values scatter relatively strongly across the burner surface.
  • the fiber knit varies over the life and thereby additionally influences the formation of flames. Since the flame ionization fluctuates due to the dependencies set out above, accurate control of the air ratio and the residual oxygen content based on the ionization current flowing through the flame is hardly possible over a large modulation range.
  • the invention has for its object to eliminate the disadvantages of the prior art and to achieve a defined flame formation in the surveillance area, so that in particular a precise air ratio control is possible.
  • the surface burner according to the invention thus has a distributor plate with a monitoring area and a main area, wherein the fuel-air mixture in the main area flows through the first fiber knit and is unaffected in the monitoring area of the first fiber knit.
  • the condition and shape of the first fiber knit fabric therefore have no effect on flame formation in the monitoring area. Rather, a flame formation in the monitoring area is independent of the first fiber knitted fabric.
  • the distributor plate is further protected by the first fiber knit especially from too high temperatures, so that the desired life of the surface burner can be achieved. Since flame formation is not influenced or disturbed by the first fiber knit in the monitoring area, it is possible to produce a geometrically well-defined flame. This creates defined flame conditions without scattering between different surface burners and without change over the life. The defined conditions allow precise control over a large modulation range.
  • a mixture outflow geometry which can be reproduced from burner to burner and thus reproducible flame parameters are created in the monitoring area on the monitoring electrode, which permit a reproducible ionization measurement from burner to burner and not age-dependent.
  • the monitoring area is formed much smaller than the main area, wherein the monitoring area has a size of about 5 cm 2 to 15 cm 2 , in particular of about 10 cm 2 .
  • the surveillance area is for example 50 mm x 20 mm in size and accordingly very small compared to the main area. A heat conduction in the distributor plate from the monitoring area in the main area, which is protected by the first fiber knit and therefore has a lower temperature, is therefore easily possible, so that excessive overheating of the distributor plate in the monitoring area is not to be feared.
  • slot-shaped outlet openings can be provided in the distributor plate at least in the monitoring area, which run perpendicular to the respective nearest edge of the monitoring area. This ensures safe heat dissipation from the monitoring area to the main area.
  • the distributor plate can be made more permeable to the fuel-air mixture than in the main area. This can be realized, for example, by virtue of the fact that the sum of the open cross sections per area in the surveillance area is higher than in the main area. In particular, with a low required power so that a relatively strong flame in the monitoring area ensures that can be used to generate a sufficient ionization signal.
  • the distributor plate may have a greater thickness in the monitoring area than in the main area.
  • the distributor plate is made of a metal or stainless steel sheet having a thickness of about 0.6 mm. In the monitoring area, the thickness of the distributor plate is then increased to, for example, 1 mm or 1.5 mm.
  • an additional metal sheet may be formed, for example, from stainless steel or a high-temperature-resistant alloy, such as a nickel-based alloy, which is welded to the distributor plate in the monitoring area. This further improves the dissipation of heat in the monitoring area.
  • a weld is in a metal fiber knit a particularly simple way to fix the first fiber knit to the distributor plate. The welding takes place for example via individual welds.
  • the monitoring area is free of the first fiber knit.
  • the generated flame image in the monitoring area is then essentially determined by the openings in the distributor plate.
  • the burner surface in the monitoring area can be completely free, so the distributor plate are open, so that the flames are generated without the interposition of a burner medium in the monitoring area.
  • the distribution plate is covered in the monitoring area downstream of a second fiber knitted fabric, which has a lower flow resistance than the first fiber knitted fabric and forms part of the burner surface.
  • the second fiber knit then causes a protection of Distribution plate in the monitoring area, but affects the flow of the fuel-air mixture but significantly lower than the first fiber knit.
  • the first fiber knitted fabric can be produced from a proven, relatively thick metal fiber fabric, which is sold, for example, under the name NIT 100 SE from Bekaert Combustion Technology.
  • the second fiber knitted fabric is very thin, with a ratio of hidden areas to holes being very small, so that the fuel-air mixture can flow through the second fiber knitted fabric virtually undisturbed.
  • Influencing the flame pattern is then essentially determined by the shape of the openings in the distributor plate and hardly influenced by the second fiber knit.
  • the second fiber knitted fabric for example, a metal fiber knit fabric offered by Bekaert under the name NIT 100 A can be used.
  • NIT 100 A a metal fiber knit fabric offered by Bekaert under the name NIT 100 A
  • the first fiber knit fabric is connected to the second fiber knit, in particular welded.
  • a welding of metal-fiber knits and different mesh sizes and thicknesses is easily possible and represents a particularly simple and durable connection.
  • the distribution plate in the monitoring area downstream of a perforated, temperature-resistant metal sheet is covered, which forms a part of the burner surface.
  • the metal sheet is made, for example, from a high temperature resistant stainless steel alloy and perforated and / or perforated. Edges of the metal sheet close to the first fiber knit fabric or are covered by the first fiber knit, so that no thermally overloaded areas arise.
  • the metal sheet protects the distribution plate in the monitored area.
  • the distribution plate is, for example, at a distance of 1 mm to 3 mm to the distribution plate in the surveillance area arranged.
  • the geometry of the perforation of the metal sheet can be produced with a very high repetition accuracy, so that a well-defined flame is obtained.
  • the metal sheet may be kept freely stretchable on the surface burner in a longitudinal direction.
  • This is possible for example by a combination of a fixed bearing with a movable bearing, wherein the metal sheet is thus fixed only on one narrow side and is displaceably mounted on an opposite narrow side and / or on the adjacent longitudinal sides.
  • the distributor plate is interrupted in the monitoring area.
  • the size of this interrupt corresponds to the size of the monitored area.
  • the flow of the fuel-air mixture is then not affected at all in the monitoring area by the distributor plate, but only by the metal sheet. Overall, this results in a very low flow resistance, so that even at low power levels, the formation of a strong flame in the monitored area is ensured.
  • the first fiber knit is penetrated in the monitoring area of nozzles.
  • the entire distributor plate can be covered by the first fiber knitted fabric and thus protected against overheating, while at the same time ensuring that the flow of the fuel-air mixture can not be influenced by the first fiber knitted fabric in the monitored area.
  • the fuel-air mixture in the monitoring area with the aid of the nozzles is passed through the layer of the first fiber knitted fabric and on this fiber knit and can thus be used to generate a defined flame.
  • the nozzles can be used simultaneously to locally hold the first fiber knit, for example, to avoid sagging of the fiber knit, which can lead to an elongation of the fabric over the life.
  • the first fiber knit for example, non-positively on the nozzles and / or held in a form-fitting manner.
  • the fiber knit is pierced by the nozzles, so to speak, whereby loops of the fiber knit are stretched. Individual fibers of the fiber knitted fabric are thus not damaged.
  • the nozzles can easily have a diameter of about 5 mm. Additionally or alternatively, the nozzles may also be welded or otherwise connected to the first fiber knit.
  • the nozzles may each have a plurality of outlet channels. It is particularly preferred that the outlet channels extend at least partially at an angle greater than or equal to 0 ° and smaller than 90 ° to a nozzle longitudinal axis. This results in a lateral escape of the fuel-air mixture, so that the flame lifts less strongly from the burner surface. This is advantageous for accurate ionization measurement in the flame and thus for the adjustment and regulation of an air ratio (residual oxygen content).
  • the nozzles are connected to the distributor plate, in particular welded or riveted.
  • the position of the nozzles with respect to the distributor plate and the monitoring electrode is then clearly defined so that the nozzles can be used to position the fiber knit.
  • the invention is also achieved by a method of monitoring flame formation in a surface burner by monitoring flame formation in a monitoring area, wherein a fuel-air mixture in the monitoring area is guided past a first fiber knit covering a main area. It can be provided that the monitoring area is kept free of fiber-fiber, so that the fuel-air mixture unhindered in the monitored area from the first fiber knit emerge from the distributor plate and can be used for geometrically defined flame formation.
  • other burner media such as a second fiber knit or a metal sheet can be used be arranged to support the distributor plate in the monitoring area and to ensure a defined flame formation.
  • FIG. 1 a surface burner 1 is shown in a spatial representation, which has a box-shaped burner frame 2, in which a mixing chamber is formed.
  • the surface burner 1 has a first fiber knitted fabric 3, which is arranged between the sides of the burner frame 2.
  • the first fiber knitted fabric 3 forms a burner surface.
  • a monitoring area 4 is free of the first fiber knitted fabric 3, so that a distributor plate 5 can be seen.
  • the distributor plate 5 extends over the entire upper side of the surface burner 1 and is covered outside the monitoring region 4 in a main region 6 of the first fiber knit 3.
  • slot-shaped outlet openings 7 are formed which in each case run perpendicular to the nearest edge 8 of the monitoring area 4.
  • a fuel-air mixture which is located in the mixing chamber within the burner frame 2, can flow through the distributor plate 5 to the burner surface above the first fiber knitted fabric 3 in the main region 6 and above the distributor plate 5 in the monitoring region 4.
  • the fuel-air mixture reaches the side facing away from the distributor plate 5 top of the first fiber knit 3.
  • the fuel-air mixture is ignited and then can form the flames.
  • a plurality of and / or larger outlet openings 7 can be provided in the area of the monitoring area 4 of the distributor plate 5 than in the main area 6. This achieves that in the monitored area 4 raised flames lift off the distributor plate 5, so that it is not thermally overloaded. At the same time, the larger volume flow provides additional cooling.
  • the first fiber knitted fabric 3 which is formed as a metal fiber knitted fabric, with the distributor plate 5, which may be formed for example as a perforated stainless steel sheet, welded.
  • the first fiber knitted fabric 3 is stabilized on the one hand, and on the other hand it is ensured that no influence of the fuel-air mixture through the first fiber knitted fabric 3 can take place in the monitoring region 4.
  • a defined flame can thus be generated in the monitoring area 4 and used for controlling the air number, that is to say residual oxygen monitoring.
  • FIG. 1 is above the monitoring area 4 no fiber knit or other burner medium arranged. But it is also possible to cover the distributor plate 5 in the monitoring area 4 with a comparison with the first fiber knitted fabric 3 lighter and / or thinner second fiber knit 21 to the distributor plate. 5 also to protect in the monitoring area from thermal stress.

  • the metal sheet 9 is formed as a perforated stainless steel sheet.
  • the first fiber knitted fabric 3 is welded at the edge 8 to the metal sheet 9. In addition, the first fiber knitted fabric 3 is welded to the burner frame 2 and so clearly positioned. In the monitoring area 4, the first fiber knitted fabric 3 can thus have no influence on the flame formation.
