Definitions

  • the invention relates to a burner arrangement, in particular for a gas burner, with a gas and an inlet supply line, both of which end in the region of a gas-air mixing chamber. with swirl-generating devices which generate a vortex flow of the gas-air mixture within the mixing chamber and in the downstream combustion zone, at least some of the combustion air flowing laterally into the mixing chamber via cross-section-changeable channels let into the mixing chamber wall.
  • a so-called dual burner is shown in DE-OS 2 729 321, in particular FIG. 12.
  • the known burner is primarily designed as an oil burner, it can also be operated with gas, the oil nozzle being bypassed with the aid of a channel which opens into the mixing chamber.
  • the gas supply is regulated by a rotatable perforated disc that gradually releases the channel by rotating the bore.
  • the air can be supplied through ducts opening laterally into the mixing chamber with the help of an actuator which controls the cross sections of the laterally opening channels changed, adjustable.
  • the task arises of specifying a small gas burner which is to be operated as economically as possible, in which preferably all or at least part of the combustion air is admitted laterally into the mixing chamber, this lateral admission being carried out by correspondingly inclining the bores already leads to the formation of a vortex.
  • the air energy is to be used to achieve a good distribution of the gas within the air flow.
  • the fuel gas or another combustible, gaseous substance is also introduced via the channels which can be changed in cross section. It is possible to determine some of the channels specifically for the gas flow. However, it is also possible to let the gas supply line run in the form of one or more strands in the mixing chamber wall, the streak or strings ending in one or more of the channels.
  • This formulation means that the respective channel alone supplies gas; however, it is also possible to blow the gaseous fuel directly into the air flow and have it carried away by the air flow.
  • the cross-section-changing member will be a lance that is adjustable within the mixing chamber, as has also been proposed according to the prior art.
  • the lance tip can have one or more Have openings for the fuel and / or air supply, wherein an additional control of the conditions in the combustion chamber is also possible.
  • FIG. 1 shows a cross section through a burner arrangement of the type that can be used, for example, for the combustion of natural gas in a domestic boiler in the order of 50,000 kcal / h.
  • the burner arrangement adjoins a boiler wall 2.
  • the burner assembly has a housing 3, which in the is essentially cylindrical in shape and comprises a plurality of parts arranged concentrically to one another. From the outside inward, the housing 3 initially surrounds a cylindrical air duct 4, to which combustion air can be supplied via a line 5 under a certain excess pressure, for example 0.1, 3 bar.
  • a cylindrical connecting piece 6 Concentrically within the air duct is a cylindrical connecting piece 6, which is fitted and held with its end face 7 in a burner holding collar 8.
  • the burner holding ring 8 which opens in a conically shaped opening with a subsequent casing tube 9 towards the boiler chamber 10, also holds the outer wall of the housing 3, as can be seen from FIG. 1.
  • the nozzle part 6 is drilled out along its entire length.
  • the nozzle part contains the so-called gas-air mixing chamber 11, the volume of which can be changed by a lance 12 movable back and forth within the nozzle part 6.
  • the front part of the lance designated by the reference number 13, serves as a control element, as will be explained below.
  • the lance can be moved back and forth manually, for example, with the aid of a lever 14, with a pneumatic device or similar devices as are known per se.
  • Numerous channels 15 open into the mixing chamber 11 from the side, which preferably have the shape of slots and which differ in their direction from the normal direction, i. H. contain a tangent to an imaginary circle within the mixing chamber 11 in its preferred direction. Clese channels 15 are therefore at the same time swirl-generating devices which generate a vortex flow with the aid of the air flowing through the air channel 4 within the mixing chamber and in the downstream combustion zone within the boiler space 10.
  • the channels 15 can be more or less closed with the aid of the lance 12, and the air supply can be metered.
  • the gas supply takes place via a feed line 17, which ends in a cylindrical distribution channel 18 and continues into a plurality of strands 19 which run within the connecting piece part 6 parallel to the axis of the lance 12.
  • the strands 19, which accordingly run at least partially within the mixing chamber wall, end within the air supply channels 15, so that the inflowing gas is directly captured by the air flow and introduced into the vortex flow.
  • ignition means not shown
  • the gas-air mixture burns within the casing tube 9 and in the boiler room 10.
  • a stable flame is produced in that the flow is relatively strongly swirled.
  • the front part 13 acts as a cross-sectional changing member for the entirety of the channels 15, so that the supply of the gas-air mixture can be regulated. As a result, the performance of the burner can be varied in a very simple manner.
  • FIG. 2 shows the details of the gas-air mixing chamber in a somewhat more detailed representation with further details.
  • numerous slots here for example 20, are let into the mixing chamber 11, through which the air can flow.
  • the air experiences a vortex flow through the appropriate tangential position of the slots.
  • a gas supply line 19 opens within a channel 15, the gas being carried along by the air.
  • the front part of the lance carries a further feed channel 20 which ends in an opening 21. Through this channel, which is guided within the lance, liquid fuels can also be introduced, for example.
  • FIG. 3 shows an embodiment in which a part of the gas line strands, here designated 23, in Openings 24 opens out, which end on the outer end face 25 of the mixing chamber 11.
  • Natural gas or related gases or gas mixtures such as metane, town gas and the like are primarily suitable as fuel. However, it is also possible to introduce a fine carbon-air mixture or an oil-air aerosol through the fuel strands 19. Within the channels 15 there is a suction effect and swirling by the air jets. which continues into chamber 11.
  • the channels can have a rectangular cross-sectional shape, but can also have a round, oval or triangular cross-sectional shape, as tests have shown.
  • the mixing chamber can be cylindrical. However, it can also, as already in the above-mentioned laid-open publication according to the prior art, be designed in a step-like or trumpet-like manner.
  • sleeves or the like can also be used on the outside over the channels 15, as is known from the prior art.
