Definitions

  • the invention relates to a burner for use in a gas hob or in an oven.
  • Gas cookers usually use standard atmospheric burners.
  • the gas / air mixture as a mixture is formed by the gas flows through a nozzle located below the burner and draws the primary combustion air in an injector.
  • the construction is carried out so that the mixture then emerges radially from a perforated ring and then burns open, wherein a portion of the ambient air as secondary air burns with.
  • a burner cap which forms the top of the burner. The burner cap is inactive, so it is transported over him as good as no heat to a pot above. This design causes the heat to be released to the pot only in the area of the open side flames.
  • the pot is heated mainly only in its edge region, while the overlying the burner cover center of the pot bottom less heated becomes.
  • Another disadvantage of the known standard atmospheric burner is the limited modulation range in which the gas / air mixture burns cleanly and stably.
  • surface burners are used in gas stoves, which are usually formed from a ceramic plate with honeycombed arranged, parallel capillaries. Such surface burners provide a homogeneous heat distribution over the entire surface.
  • a major disadvantage is that the combustion zone is defined and limited by the burner surface. As a result, only a corresponding pot size can be used for a particular burner size.
  • Another disadvantage is the relatively long heating and cooling of the ceramic plate due to their heat capacity.
  • the invention has for its object to provide a burner mentioned above, can be reduced or eliminated with the disadvantages of the prior art and in particular a better combustion and better heat generation can be achieved on an object to be heated, such as a pot.
  • the burner has a supply line for a mixture of fuel gas and combustion air, as is usually provided. This is followed by an open combustion zone for this mixture in which the mixture burns with an open flame.
  • a catalytically active and gas-permeable body is arranged between the gas supply line and the said combustion zone. The mixture flows through this body to the combustion zone. Due to the special catalytically active formation of the body, the mixture is already partially oxidized or burned on the catalyst in a first combustion stage. This partial oxidation or combustion, with a corresponding design of the burner, enables heat generation or heat generation in the region of the body itself and not only in the combustion zone, which is usually surrounding the body, ie annular. The body can then this heat to a pot or the like. give off, advantageously by direct heat conduction or contact heat.
  • the body has lateral outlets, which are adjoined by the open combustion zone or which pass into the open combustion zone.
  • the portion of the mixture that has not yet been burned within the body exits into the open combustion zone where it is mixed with secondary air and burned according to a conventional open-flame gas burner.
  • This combustion forms a second combustion stage, so to speak, while within the catalytically active body the first combustion stage takes place.
  • This two-stage combustion does not allow only an overall better or more efficient combustion of the mixture, in particular due to the catalytic properties of the gas-permeable body.
  • the body can serve both for gas distribution, as is already customary in gas burners, from the more point-like supply of the fuel gas to the body surrounding the annular combustion zone, as well as due to the first combustion occurring in it for heat generation within the annular open combustion zone.
  • heat transfer in the middle can take place, for example, in the case of a pot in its vicinity or even directly, and not only annularly. This also results in a better surface distribution of heat.
  • a catalytic burner which operates under normal atmospheric pressure for domestic and industrial use. It exhibits high energy efficiency due to the combined and simultaneous use of radiant and / or thermally conductive heating mechanisms together with the known convection mechanism by combustion gas, and is characterized by a significant reduction in pollutant emissions such as CO, unburned hydrocarbons and NO x .
  • the body can be made in one piece.
  • it has disc shape, particularly advantageous round disc shape.
  • the dimensions may be such that its diameter is four times to one hundred times, preferably five times to twenty times, as large as its thickness, thereby giving it a rather weak or strong flat shape.
  • the body may have a gas-tight upper side and / or a gas-tight underside.
  • At least one gas-tight bottom through which only the supply line can lead the mixture of fuel gas alone or fuel gas and combustion air prevented an undesired escape of mixture in a region, namely under the body, where this is not desired and also only a very unfavorable combustion would be possible.
  • a gas-tight top prevents the escape of mixture, where it also can not be burned and should not escape.
  • the function of the diversion of the mixture from the supply line to the combustion zone is improved by such gas-tight upper and lower sides.
  • a cover may advantageously be arranged.
  • This cover serves to complete this side of the body surface and / or gas-tight with the aforementioned advantages.
  • the cover is advantageously closed and may for example consist of metal such as stainless steel or the like, glass or glass ceramic or ceramic. Silicon-based ceramics are suitable here, for example silicon carbide or silicon nitride.
  • the cover can also be designed as a pot carrier, so as to park an aforementioned pot on it. Then you can do without an additional carrying frame.
  • the cover may be a continuous disc, which also laterally covers the gas-permeable body and thus also covers or covers the combustion zone.
  • glass or glass ceramic covers as well as the aforementioned ceramic covers.
  • the heating of a raised pot then takes place, on the one hand, through the annular area above the open combustion zone, whose generated heat radiates through the cover or also passes through as contact heat and heats the underside of the pot. In the central region of the pot is also heated by the heat generated in the first combustion stage, so that a large-area and not only annular heating is achieved.
  • the cover or the like good properties for heat transport from the combustion to a pot. having.
  • a heat transfer can take place in the form of heat conduction and / or thermal radiation.
  • a heat transfer in particular by means of heat radiation, take place in a furnace chamber of an oven mentioned above.
  • a carrier for the body In a further embodiment of the invention is located under the body, a carrier for the body. This carrier can also take over the aforementioned sealing function of the underside of the body, for which purpose it is disc-shaped and flat. Only the supply line for the fuel gas or mixture passes through the carrier.
  • a heat-insulating layer may be provided between the carrier and the body. This thermal insulation ensures that the heat generated during combustion goes in the direction in which it is desired, that is, for example, in the direction of a set up on the burner pot. Furthermore, this heat-insulating layer should be gas-tight, at least on its surface towards the body, so that no mixture can enter or escape through it.
  • the body such that the mixture flows from the inside, in particular centrally from the said gas supply line, to the outside to the combustion zone.
  • the gas should flow substantially parallel to the flat extent of the body. This also simplifies the gas-tight closure on the top and bottom of the body.
  • the burner has an ignition electrode and a monitoring electrode in the open combustion zone or very close thereto. These can be in combined form or training, so that the effort is less. Basically, such combined Ignition and monitoring electrodes known. As an alternative to a combined ignition and monitoring electrode can be used as a monitoring electrode and a thermocouple. Then a separate ignition electrode is necessary.
  • the burner advantageously has a round design, particularly advantageously by a round design of the gas-permeable body.
  • a round design of the gas-permeable body advantageously has an approximately equally long flow path from the supply line into the body is achieved up to the combustion zone.
  • the gas supply within the combustion zone is as even as possible.
  • such an adaptation to the usually round shape of a saucepan is optimal.
  • the burner in the horizontal plane or in plan view and in particular the gas-permeable body to have a different shape from the circular or circular shape, for example, be rectangular.
  • a circumferential ring is arranged with holes or slots as a kind of perforated ring.
  • a defined flame pattern can be generated in the open combustion zone, since the mixture emerges from respectively identical and exactly defined openings of the ring.
  • Such a wreath may consist of correspondingly heat-resistant metal.
  • the gas-permeable body itself can be formed integrally or monolithically in an embodiment of the invention.
  • the said gas line function is easily accessible.
  • it may have a foam-like structure, which serves as a substrate or base for the mentioned catalyst.
  • Such a body may for example consist of FeCrAlY, SiC, mullite, cordierite, Al 2 O 3 or ZrO 2 . Foaming of such materials is well known to those skilled in the art and does not pose a major technical problem.
  • the body may consist of a thick mat formed by threads or gauze. Similar to the aforementioned foam-like structure, the mat serves as a substrate for the catalyst. As materials for the mat, the aforementioned offer.
  • the application of the catalyst to the gas-permeable or textile or porous, foam-like structure of the body is carried out with customarily suitable catalysts in the usual manner.
  • immersion methods are suitable here in which a catalyst dissolved in liquid or a slip is applied and then solidified or hardened, advantageously at high temperatures.
  • a noble metal such as platinum, palladium or rhodium, a perovskite, an aluminate or a mixture of these materials may be used.
  • Suitable slurries include Al 2 O 3 , lanthanum-stabilized Al 2 O 3 or ZrO 2 .
  • heat radiation and direct heat conduction take place in the central region of the burner, resulting in a more efficient heating of the center of the pot.
  • Overheating of the edge areas of the pot is avoided as well as energy losses that result from the flames burn past the side of the pot.
  • the entire heat of combustion is better utilized and the efficiency is increased. This leads to shorter warm-up and cooking times and thus lower energy consumption.
  • the food gets a more uniform temperature distribution. Local heating or even burning of the food in the edge region of the pot, while it is still cold in a central region, is thus avoided.
  • Combustion within the body in the first combustion stage is more stable than open combustion in standard atmospheric burners. This generally increases the power modulation.
  • the first combustion can also be controlled well by the mixing ratio of gas and supplied air.
  • the control of the temperature of the catalyst in the partial oxidation can be achieved by adjusting the feed ratio ⁇ between air and fuel so that the oxygen of the fuel-primary air mixture is the limiting influence in any case. It determines the exact amount of heat generated on the catalyst and the amount of heat, the power dissipated to the pot by radiation and / or direct heat conduction.
  • the flame size can be easily varied due to the radial open secondary combustion by adjusting the fuel supply and optimally adapted to different pot sizes. It can be used on a burner different pot sizes and high Ankochsten and low heat retention performance can be set. Since part of the combustion reaction already takes place in the catalytically active body and thus locally separated from the open combustion in the second stage, lower combustion temperatures and thus lower NO x emissions. In general, less exhaust gases are produced in this two-stage combustion.
  • the partially converted gas mixture is characterized by a lower calorific value due to the previous heat release to the pot from radiation and / or direct heat conduction. It is therefore possible to reduce the pollutant emission of NO x in the exhaust gases of partially premixed atmospheric gas burners by reducing the adiabatic flame temperature of the mixture without using excess air or recirculation of exhaust gases and without increasing the emission of CO and unburned hydrocarbons.
  • the burner can also be used with fuels, such as hydrogen in pure or mixed form, which are characterized by extremely high adiabatic temperatures. Otherwise, these lead to the formation of large amounts of NO x during combustion in conventional flame diffusion burners.
  • the cover When using a cover of transparent to IR radiation glass material such as glass ceramic or the like. the proportion of radiation can be increased and made visually recognizable. The user sees, so to speak, the benefits of the central radiant heat. Furthermore, the cover can at least partially consist of the same material as the entire working surface of the gas hob and thus contribute to a continuous design. Alternatively, it may be made of a material with high radiation and heat conduction such as SiC, cast iron, stainless steel or iron-chromium alloys. The cover can also take over the function of the pot carrier. This can improve the cleanability of the hob and save the cost of additional pot carrier.
  • the burner concept according to the invention is so compact and flexible that it can also be used under a continuous glass or glass-ceramic cooktop panel. This offers advantages in the cleanability of the cooking surface. Even in an oven, the use of the burner according to the invention is possible.
