Definitions

  • the present invention relates to a burner for gas combustion systems with a flame tube, an ignition device and a gas tube, at one end of which a gas nozzle and a baffle plate are arranged inside the flame tube and the other end of which can be coupled to a supply line outside the flame tube.
  • Such burners which are provided for example for domestic heating, are used to mix the fuel gas with air and to ignite the gas / air mixture.
  • FIG. 2 Such a known burner is shown in FIG. 2 and comprises a housing 10 in which a fan 12 is arranged. Via an air duct 16, the air sucked in by the fan 12 and an air filter shown in broken lines is passed into a flame tube 14 which is fastened to the housing via a tube flange 18.
  • a gas pipe 20 is also arranged on the pipe flange, at one end of which a gas nozzle 22 is arranged inside the flame pipe 14 and the other end of which can be coupled to a supply line outside the flame pipe.
  • a baffle plate 24 and a perforated disk 26 are located within the flame tube at the front end of the gas tube 20.
  • An ignition device 28 and an ionization electrode 29 serve to ignite the air / gas mixture and to monitor the combustion process.
  • the burner output can be adjusted and adapted to the different boiler outputs by mounting different baffle plates and perforated plates on the front end of the gas pipe.
  • the burner output can be varied in three areas using three different sets of baffle plates and perforated plates and thus adapted to the required boiler output.
  • 3 shows three power ranges a, b and c (a: 11-29 kW; b: 22-59 kW; c: 38-90 kW), which are achieved by three different sets of dust disks and perforated disks a, b, c can.
  • baffle plate and / or the perforated plate must be installed before or afterwards in order to vary the burner output.
  • this requires the provision of a wide variety of baffle plates and perforated plates, on the other hand, these must be installed before installing the burner, which requires a great deal of time and material.
  • the solution according to the invention ensures that the performance range of the burner can be varied over a wide range (approx. 15-85 kW) without installation work would have to be carried out, or that different sets of baffle plates and perforated plates would have to be made available, only conventional components being used at the same time.
  • the baffle plate and / or the gas nozzle are arranged displaceably in the region of the constriction of the flame tube within the flame tube. In this way, by moving the baffle plate and / or the gas nozzle, the air flow that passes through the flame tube can be regulated, ie the pressure within the flame tube is varied.
  • this does not take place by exchanging individual components of the burner, but merely by moving the baffle plate and / or the gas nozzle within the flame tube, it being possible for the setting to be carried out before the burner is installed.
  • the solution according to the invention has also made the provision of a perforated disc superfluous, since the pressure within the flame tube is carried out by moving the baffle plate and / or the gas nozzle relative to the constriction. As a result, the cost of materials and spare parts is significantly reduced.
  • the burner according to the invention can be used universally in a wide variety of heating systems with different boiler outputs, without having to take a certain boiler output into account when manufacturing or installing the burner. This also significantly reduces the overall cost of the burner.
  • the baffle plate and / or the gas nozzle are displaced by a device which can be actuated outside the flame tube.
  • the burner output can be varied and adapted even after the burner has been attached to the heater, without the burner having to be removed from the boiler. This further improves service friendliness.
  • the gas tube inside the flame tube consists of an outer and a coaxial inner part pipe of different diameters, one part pipe being slidably received in the other, fixed part pipe and sealed against it by a seal.
  • the device for displacing the baffle plate and / or the gas nozzle can be formed by a rod which is fastened to the displaceable partial pipe and leads out of the flame pipe. It is also particularly advantageous if the rod is rotatably fastened to the displaceable partial tube and is received via a thread in a nut fixed to the housing. As a result, the burner output can be varied by turning the rod even while the heating is running.
  • the ignition device, the dust disk and the gas nozzle can advantageously be moved together.
  • the angle between a tangent of the constriction and the inner wall of the flame tube can be between 20 ° and 30 °, advantageously 25 °, or between 30 ° and 45 °.
  • the setting sensitivity of the burner output can be varied by the choice of the angle, which contributes to an optimized heating efficiency.
  • the burner according to the invention shown in FIG. 1 basically has a similar external structure to the known burner from FIG.
  • the flame tube 14 is connected to the housing 10 via tube flanges 18 and 19.
  • a gas tube 20 Within the flame tube 14 there is a gas tube 20, the outer end (right in FIG. 2) of which extends out of the housing 10 and opens into a metal block 30 connected to the housing, which serves as a gas tube receptacle.
  • a gas supply line (not shown) is connected to the metal block 30, and a wide variety of valves and regulating devices can be provided between the gas supply line and the metal block.
  • the gas tube 20 extends from the metal block 30 coaxially to the flame tube 14 in the interior of the flame tube.
  • the gas pipe 20 is composed of an outer part pipe 20a and an inner part pipe 20b, which are slidably received coaxially one inside the other.
  • the two partial tubes 20a and 20b are sealed by an O-ring 32 which is received in a groove of the inner partial tube 20b.
  • a baffle plate 24 is also provided at the front end of the inner gas tube 20b, the baffle plate being arranged in a plane which is perpendicular to the axis of symmetry of the flame tube.
  • the inner cross section of the flame tube is provided with a constriction 34 in the front third of the flame tube, which constricts the inner cross section of the flame tube.
  • the front end of the inner gas tube 20b, on which the gas nozzle 22, the baffle plate 24, an ignition device 28 and an ionization electrode 29 are located, is arranged in the region of the constriction 34.
  • a rod 36 is rotatably fastened to the inner gas pipe 20b and extends out of the housing 10 parallel to the gas pipe and the flame pipe.
  • the rod 36 is received on the housing 10 in a thread 37 fixed to the housing, the end 38 of the rod 36 on the housing side being provided with an opening for an Allen key 39.
  • the angle ⁇ between a tangent of the constriction 34 of the flame tube 14 and the inner wall of the flame tube is approximately 30 °.
  • the fan 12 draws in outside air, which is passed via the air duct 16 of the housing 10 into the interior of the flame tube 14 (arrow A).
  • gas is fed into the metal block 30 via the outer gas supply line, and from there passes through the gas pipe 20 to the gas nozzles 22.
  • the gas / air mixture is ignited by the ignition device 28, the combustion process being carried out by the ionization electrode 29 is monitored.
  • the mixing of the gas and air flow within the flame tube takes place through the baffle plate 24 in connection with the constriction 34 of the flame tube 14.
  • the rod 36 is rotated with the help of the Allen key 39, whereby the inner gas pipe 20b is slid inside the outer gas pipe 20a (arrow B).
  • the distance between the constriction 34 and the baffle plate 24 or the gas nozzles 22 changes at the same time.
  • the air passage area between the constriction 34 and the baffle plate 24 is thus changed, i.e. the pressure is varied.
  • this variation can also take place with the burner installed and already running. This allows the burner output to be adapted to the boiler output in a particularly simple manner, without the burner having to be dismantled.
  • the angle ⁇ between a tangent of the constriction and the inner wall of the flame tube can be reduced.
  • FIG. 4 shows the power range that can be achieved with the burner according to the invention.
  • a comparison with FIG. 3 shows that this is a very large one Power range from 16 to 82 kW can be achieved, which is achieved in the prior art only by different baffle plates or perforated plates.
  • this area can be varied by changes to the baffle plate or to the constriction, if necessary.
  • such a large performance range can be achieved with only one baffle plate, it being possible entirely to dispense with the perforated disc known from the prior art.
