Definitions

  • the invention relates to a burner for combustion plants with a subsequent mixing device.
  • Burners of this type have the disadvantage that the chimney draft has a lasting effect on the recirculation, so that the optimum firing conditions and thus optimal fuel utilization are often not achieved.
  • the mixing device is designed as a vortex resonator.
  • the advantage of this solution is that the burning stability and thus the fuel utilization is improved, but above all it becomes independent of the chimney draft, so that the external combustion conditions can change within wide limits without reducing the heat generation related to the amount of fuel. Furthermore, the turbulence in the resonator is improved and the combustion is facilitated at the points of high vibration amplitudes, so that in addition to the increased combustion stability, the burner also increases in efficiency.
  • the noise development is not significantly above the usual flame noises, since the resonator is acoustically closed.
  • the arrangement is particularly advantageous for burners with low outputs of approximately 1 kg of fuel per hour, since experience has shown that these are particularly susceptible to changes in the combustion conditions.
  • a particularly effective embodiment of the invention is that the resonator is tubular and has baffles on the inside.
  • baffle surfaces are designed as a system of successive rings and surfaces abutting the resonator wall.
  • the resonator which glows as a result of the combustion process, acts as a support for the combustion through the radiation inside the resonator.
  • baffles and four rings are particularly favorable, especially if the first annular baffle is located approximately 3 cm from the burner nozzle, the last ring at the end of the resonator and the other baffles and rings are arranged approximately equidistantly therebetween.
  • baffle plate usually arranged in the vicinity of the burner nozzle with additional openings.
  • a resonator length of approximately 18 cm and a diameter of approximately 12 cm have proven to be very favorable. This creates vibrations of around 400-600 Hz, which lead to a stable flame, have little acoustic radiation and result in a small burner that can be easily fitted into existing boiler systems.
  • the resonator can consist of metal, but is made of ceramic materials for long service lives.
  • a resonator is provided with an adapter device.
  • the baffles are adjustable along the burner path to set the optimal operating conditions.
  • baffles that are inclined against the axis of the resonator and rotatable against each other.
  • the hot exhaust gas at the end of the resonator can be deflected by a deflection device, because this enables the hot exhaust gases to impact a larger burner area.
  • FIG. 1 shows a section through a resonator
  • Figure 2 shows the perspective view of R esona to re in sets.
  • an adapter device 1 is pushed onto a burner, for example an oil burner 2, to which a resonator tube 3 is attached.
  • the fuel emerging from a burner nozzle 4, together with the air compressed by a blower 5, is thrown against a first baffle 31 provided with a bore, first deflected by a ring 32 and then directed against a further baffle 33. Further rings 34, 36, 38 and baffles 35, 37 follow.
  • the baffle system 31 to 38 consists of refractory ceramic and is inserted into the resonator 3.
  • the resonator 3 can be made of metal.
  • the entire system can also consist of one piece of ceramic. Or else, the entire system is made of scale-free metal.
  • the baffle plate 40 arranged near the burner nozzle can be provided with additional openings.
  • the baffles can be of any shape. However, they must result in sufficient swirling and simultaneous stabilization of the flame. In particular, they can also consist of ceramic pieces held in a holding sieve. Catalytically active substances can also be used as impact surfaces.
  • the hot gas flow can be diverted radially by a deflection disk 41.
  • a deflection disk 41 Such deflecting means, which can also be used for directions other than radial, if this should be necessary through the burner chamber, no longer influence the flame, since these are so-called by the invention Middle bar ili si ert i st,
  • a burner can be optimized for the respective chimney and the desired output in each case by adjusting the baffle system using spacer rings 42.
  • spacer rings 42 can be used.
  • other known means for adjusting the impact surfaces can also be used.
  • a resonator other than the tubular one for example a plate-shaped one, can be used, in which the combustion takes place approximately radially.
  • the baffles are then rings, which are mutually arranged on the wall plates of the resonator.
  • FIG. 2 shows an insert with a baffle plate (a) and an insert with ring (b) in a perspective view.
  • Such inserts are inserted in a resonator according to Figure 1 '.
  • the shock lies in the flow shadow, so that the Meta II resonator is covered.
