Definitions
- the invention is based on an atmospheric gas burner for heaters and a gas distribution device for Gas burner according to the genus of the main claims.
- atmospheric gas burners especially larger ones, it is known that the combustion air supply is along the burner surface is often uneven.
- the reasons for this can be and will be of different types in particular through those downstream of the gas burner Components of a heater, such as the combustion chamber and heat exchanger certainly.
- the combustion chamber is airtight towards the atmosphere is complete
- less combustion air available stands as in the marginal areas, because over the central arranged injectors, or mixing tubes less primary air is sucked in than over those in the Edge areas of the gas burner are arranged.
- Gas distribution device with different nozzle sizes equip.
- the arrangement according to the invention with the features of Main claims has the advantage that in a simple manner and Way of influencing air numbers along the Burner surface is possible. Through the targeted Air ratio control increases combustion stability and reduced pollutant emissions at the same time.
- the different distances between the gas nozzles and the Entry level of the mixing tube openings are in advantageously achieved in that the Gas distribution device on the nozzle assembly side is graduated.
- An alternative solution is to mix the mixing tubes or to train the mixing pipe system in stages.
- the one intended for the atmospheric gas burner is distinguished characterized in that the cross section of the channel that the individual nozzles supplied with fuel gas, from the beginning of the channel to Channel end decreases. This ensures that in particular with longer gas distribution channels due to friction occurring pressure losses are compensated and at all Gas nozzles of the gas distribution device the same pressure is present.
- the narrowing of the cross section in the base part of the Gas distribution device formed channel is thereby achieved that the u-shaped channel in the base part by a with a wedged lid is completed, whereby the wedge protrudes into the channel so that the Cross section reduced from the beginning of the duct to the end of the duct.
- Figures 1a and 1b show the stepped Execution of a gas distribution device for one atmospheric gas burner in the mixing tube area
- FIG. 2 the representation of an atmospheric gas burner with a tiered training of the mixing tubes or Mixing pipe system.
- FIGS. 1a and 1b show a gas distributor device 10 which consists of a base part 12 and a lid-shaped closure part 14.
- gas nozzles 16a-f are distributed at regular intervals.
- the gas distribution device 10 is arranged opposite a mixing tube system 18 with individual mixing tubes 20, the gas nozzles 16a-f of the gas distribution device 10 being centrally opposite the openings of the individual mixing tubes 20 at a distance ⁇ n .
- the side of the base part 12 in which the gas nozzles 16a-f are arranged is of stepped construction.
- the gradation of the base part 12 results in different distances ⁇ n between the exit plane of the gas nozzles 16a-f and the entry plane of the injector tube openings.
- the two gas nozzles 16c, d arranged centrally on the base part 12 are at a distance ⁇ 1 from the entry plane of their corresponding mixing tube openings, while the gas nozzles 16b, e arranged therefrom on the left or right are at a distance ⁇ 2 from the entry plane of the mixing tube openings ,.
- the gas nozzles 16a, f arranged on the extreme left and right are spaced apart by a distance ⁇ 3 from the mixing tube openings, where ⁇ 1 > ⁇ 2 > ⁇ 3 .
- the different distances ⁇ n of the gas nozzles 16 to the mixing tube openings make it possible to control the primary air intake in a targeted manner.
- the gradation or the distances ⁇ n are selected such that in the edge regions of the mixing tube system 18 with the distances ⁇ 3 of the gas nozzles 16a, f from the entry plane of their corresponding mixing tube openings, via which exits from the gas nozzles 16a, f Gas flow the smaller amount of combustion air is entrained.
- the correspondingly larger distances ⁇ 2 and ⁇ 1 are used to inject more combustion air into the mixing tubes 20 via the gas nozzles 16b, e and 16c, d, respectively.
- Such an influence on the air ratio can be used in particular in gas-powered heating devices which have a closed combustion chamber and where all the combustion air required for superstoichiometric combustion is already provided with the primary air intake. Devices of this type show the tendency that, with the gas nozzles at an equal distance from the mixing tube openings, more combustion air is supplied in the edge regions.
- the lid-shaped is Locking part 14 of the gas distribution device 10 is a wedge 22 arranged, which when the base part 12 with the closure part 14 inside the base part 12 arranged channel 24 extends over its entire length, channel 24 being the gas supply for the individual Gas nozzles 16 takes over.
- the channel 24 protruding wedge 22 reduces the cross section of the Channel 24 Gas distribution channels caused by friction Pressure losses are compensated, so that at all gas nozzles 16 Gas distribution device 10 is the same gas pressure.
- Figure 2 shows the second embodiment of the invention, in which the same components are provided with the same reference numerals.
- the different distances ⁇ n between the gas nozzles 16a-d and the entry planes of the mixing tube openings are realized in that the mixing tubes 20 have different lengths or that the mixing tube system 18 is of stepped construction.
- the distances ⁇ 2 in the edge region of the mixing tube system 18 are smaller than the distances ⁇ 1 in the central region of the mixing tube system 18.
- the mixing pipe system 18 is followed by a mixing distributor space 26 for the fuel gas / air mixture, which is closed at the top by a burner deck 30 constructed from ribs 28.
- a burner deck 30 constructed from ribs 28.
- the fuel gas-air mixture flowing between the ribs 28 is ignited via an ignition device, not shown, and brought to combustion.
