  • a defined switching threshold temperature furnace space, duration of the first operating state, etc.
  • Such a method is for example from the EP 0 343 746 A2 known.
  • the burner does not work with a combustion chamber, but combustion air and fuel are passed directly into the furnace chamber, depending on the temperature in the furnace chamber.
  • the burner is switched to a first operating state, in which the fuel is supplied via a first fuel supply before entering the furnace chamber of the combustion air, wherein the resulting mixture is introduced from the side wall of the furnace chamber in this spaced apart.
  • the burner is switched to a second operating state by the first fuel supply is closed and a second fuel supply is opened.
  • the second fuel supply opens at a predetermined distance from the combustion air supply and a predetermined distance from the wall of the furnace chamber in this.
  • An above-mentioned method with two operating states is further from the EP 0 685 683 B1 known.
  • the burner is switched to a first operating state.
  • fuel is supplied to a combustion chamber via a first fuel supply, which ends in the vicinity of an outlet opening of an air supply device.
  • the fuel is mixed with the supplied combustion air and the resulting mixture is ignited via an ignition electrode arranged in the chamber, whereupon it burns in the combustion chamber and heats a furnace chamber associated with the combustion chamber.
  • the burner is switched to a second operating state by the first fuel supply is closed and a second fuel supply is opened.
  • the second fuel supply ends approximately at the height of the outlet opening of the combustion chamber. In the second operating state, fuel is no longer supplied to the combustion chamber, so that the combustion process in the combustion chamber is substantially completely suppressed.
  • a method for operating a high-temperature burner in which in a chamber, a fuel / combustion air mixture is formed and ignited by means of an ignition device, the combustion of the fuel / combustion air mixture is maintained in the chamber for a first period of time, then the fuel supply for a second period of time is reduced such that the combustion stops and remains exposed, wherein in the second period the temperature in the chamber drops below a first set temperature, and finally, after the temperature in the chamber has dropped below the first set temperature, increases the fuel supply is so that the combustion of the fuel / combustion air mixture is used due to the cooled chamber only when entering the furnace chamber and maintained.
  • This high-temperature burner comprises a chamber opening into a combustion chamber, leading to the chamber combustion air supply and disposed in the chamber mixing device having a plurality of combustion air passages on at least two circles the mixing device are arranged.
  • the mixing device itself shuts off the combustion air supply to the chamber, i.
  • the combustion air passes through the mixing device into the part of the chamber in which the combustion (start operating state) or the mixing (working operating state) takes place.
  • the center of the above circles on which the combustion air passages are arranged may coincide with or be offset from the axis of the chamber. It is also possible that the center of at least one circle coincides with the chamber axis, but the center of at least one further circle is offset from the chamber axis.
  • At least one combustion air passage is arranged on each circuit, this arrangement (in the case of a circular-cylindrical configuration of the combustion air passages) being carried out such that the center of a given combustion air passage the respective circle lies.
  • the arrangement of combustion air passages "on a circle” is to say that the openings of the combustion air passages are arranged on the circle - the circles themselves are not a structural feature of the burner.
  • a plurality of combustion air passages is arranged on a circle, wherein it is preferable on the same consideration that the centers of the circles coincide with the chamber axis.
  • the combustion air passages extend through the mixing device and are preferably made cylindrical, and from a production point of view, it is particularly preferred that these are designed circular-cylindrical.
  • the high-temperature burner further comprises a fuel supply, which ends in a fuel discharge device downstream of the mixing device, that is, the fuel discharge device is arranged on the furnace chamber side of the mixing device.

  • a high-temperature resistant material such as ceramic or a corresponding steel alloy
  • combustion air passages are further arranged on the mixing device or the at least two circles such that an outer annular space of the mixing device is free of combustion air passages. Such an arrangement of the combustion air passages has the consequence that no combustion air enters the chamber itself in the vicinity of the chamber wall.
  • the combustion air passages each have an angle of attack ⁇ x > 0 ° to the chamber axis and a radial swirl angle ⁇ x , wherein an angle of attack ⁇ a of the combustion air passages on the outermost circle is smaller than an angle ⁇ i of the combustion air passages on the innermost circle, and wherein the helix angle ⁇ a of the combustion air passages on the outermost circle is greater than the helix angle ⁇ i on the innermost circle, and wherein the helix angle on the outermost circle is between 5 ° and 60 °.

  • the twisting of the combustion air provides stable combustion in the starting operating state of the combustion air-fuel mixture within the chamber, and the decrease of the helix angle from the outermost to the innermost circle ensures that fuel and combustion air inside the chamber are not mixed too much. Furthermore, the twisting is chosen so that in the working operating state, the combustion is not sucked into the chamber, but takes place at a convenient distance from the chamber outlet in the furnace chamber.
  • the combination of the above measures has the consequence that in the start operating state, the flame generated in the chamber has no contact with the chamber wall, thereby ensuring that the temperature of the chamber wall during the start-up operating state does not rise above the ignition temperature of the fuel / combustion air mixture. Due to the duration of the start operating state heating of the chamber wall on the ignition temperature is excluded by the radiant heat of combustion.
  • the transition to the working operating state is performed such that the fuel supply is turned off for a short time, so that the combustion in the chamber stops.

  • the fuel outlet means comprises a fuel lance axially parallel to the chamber axis extending into the chamber and having the fuel passage at the lance end. At least 50% of the fuel is directed into the chamber via this lance.
  • the high-temperature burner itself is exposed during startup and shutdown high temperature fluctuations, which also occur within a short period of time, so that in particular the material of the mixing device and the fuel outlet device and the chamber is exposed to high thermal requirements.
  • the fuel outlet device has been found that it is preferred that the end face is beveled to the lateral surface, since voltages are better dissipated during heating and cooling of the fuel outlet device by this configuration of the fuel outlet device.
  • the combustion air passages are arranged on a plurality of circles on the mixing device, wherein the center of the circles may coincide with the chamber axis or be offset therefrom.
  • the combustion air passages are arranged on three circles on the mixing device, wherein the angle of attack increases from the outermost circle to the innermost circle and the radial twist angle decreases from the outermost circle to the innermost circle.
  • the combustion air passages are arranged or dimensioned so that more than 75% of the combustion air amount at the outermost circle and less than 25% of the combustion air amount at the innermost circle pass through the mixer, such distribution of the passing air quantity being by the size and / or the number of combustion air passages can be achieved.
