Definitions

  • the invention relates to a gas burner, in particular an atmospheric gas burner with primary air premixing, with a burner ring having gas outlet channels and with a burner cover which may be formed in one piece therewith.
  • Gas burners for cookers are known in various designs.
  • the known burners have flame outlet openings, which are designed as slots, millings or bores, which are generally directed radially outward from an imaginary center of the burner.
  • burner designs deviating from conventional burner types have been developed, such burner designs are shown, for example, in DE-37 09 445-A1.
  • the object of the invention is to provide a solution with which, in particular in the case of atmospheric burners, the NO x content in the exhaust gas and the CO content are considerably reduced over a large control range between the small and large positions of the burner.
  • the central axis of the gas outlet channels has an angle deviating from 0 ° to a radius assigned to the respective outlet opening.
  • the inclination of the gas outlet channels relative to an imaginary assigned radius results in a particular swirl.
  • the gas / air mixture is swirled after the outlet through the outlet channels designed according to the invention in a screw-like manner, ie in a spiral-like manner, as a result of which optimum combustion occurs. This reduces CO and NO x .
  • An additional advantage is that the flames cannot find the shortest path from the flame outlet opening to the rim of the pot when the pot is in place, but are forced to stay longer under the bottom of the pot, resulting in a kind of screw flow below the bottom of the pot.
  • the flame energy can be used much better, ie in order to achieve the same cooking performance, the burner can either be in operation for a shorter period overall or can be operated with a reduced setting, which results in inevitably results in a lower overall pollution of the environment.
  • the slots can be designed as bores, they can have a straight or curved course both in their axial direction and in their cross-sectional shape, V-shaped cross-sections can be provided as well as channels of different sizes arranged in parallel next to each other, which results in optimal regulation between partial load and full load.
  • additional outlet openings for forming auxiliary flames can also be provided.
  • the burner cover In order to be able to better adapt the flow conditions to the respective applications within the burner, it may be expedient to provide the burner cover with a flow guide cone and / or with swirling / cooling fins.
  • the flow channels inside the burner can also be designed differently according to the invention.
  • the gas burner shown partially in section in FIGS. 1, 1a, generally designated 1, has the following structure: From below, a burner stand 2 with an injector 20 passes through an indicated gas trough 3. The area of the burner stand which projects beyond the gas trough 3 is surrounded by a plug-on attachment 4 onto which a burner ring 5 is mounted, which is shown in part in supervision in FIG. 1. The burner is closed off at the top by a burner cover 6, which in the example shown in FIG. 1 is centrally equipped with an inward-pointing flow cone 7.
  • the burner ring 5 is equipped with a plurality of gas outlet ducts 8 whose deviating by an arrow in Fig. 1a central axis 9 defined in an of 0 o Angle to the corresponding, designated 10 radius, the angle is designated in Fig. 1a with ⁇ .
  • the free outlet end of the gas outlet channels 8 bears the reference symbol 8a.
  • Fig. 6 similar to Fig. 1a, the burner ring 5 is shown in supervision with indicated flames 11, which are recognizably not directed radially outwards, but have an angle to the radial flow, such that there is a vortex formation.
  • the channels 8 shown in FIGS. 6 and 1a are straight there in supervision, in FIG. 7 the possibility is shown to make these channels arcuate.
  • the channels reproduced there have the reference symbol 8 ', the flames formed have the reference symbol 11'.
  • channels 8 or 8 ' can be straight or curved when viewed from above, they can have a wide variety of cross-sectional shapes; a selection of these cross-sectional shapes is indicated in FIG. 9.
  • channels of circular cross-section can also be provided, this is indicated in FIG. 9 by 8 ′′, or adjacent ones with different cross-sectional sizes, this is indicated in FIG. 9 by 8 ′′.
  • gas outlet slots or bores can be provided below the gas outlet channels, in order to e.g. to form auxiliary flames at full load, which is indicated in FIG. 2 by an arrow 12, while the gas flow course through the gas outlet channels 8 is designated by 13.
  • Fig. 3 it is also shown that additional openings 14 can be provided to suck in secondary air from below the trough 3, which is used for flame cooling, the flow path of this secondary air is designated by 15 in Fig. 3.
  • the burner cap is designated 6 throughout, even if it has a cross-sectional shape or edge design that differs from other representations.
  • the curved flow cone is designated by 7 (FIG. 8a) and by 7 'in the straight course in the case 8b.
  • cooling fins 16 may also be provided in the cover 6, for example, which may have a spiral shape for pre-swirling or may also surround the flow cone concentrically, different cross-sectional shapes are shown in FIGS. 5a and 5b.
  • 11 to 15 show different designs of the respective course of the gas outlet channels 8 relative to the free front edge 6a of the burner cover on the one hand and 5a of the burner ring on the other hand relative to the outlet opening 8a.
  • Fig. 11 shows a configuration in which these three elements, i.e. Free outer edge 6a of the burner cover 6, outlet opening 8a of the flow channels 8 and outer edge 5a of the burner ring 5 are exactly aligned with one another.
  • FIG. 12 shows a configuration in which the free outer edge 6a of the burner cover 6 projects beyond both the gas outlet opening 8a and the free outer edge 5a of the burner ring 5.
  • Fig. 13 the free edges 6a and 5a protrude beyond Gas outlet openings 8a.
  • FIG. 14 shows a design similar to FIG. 13, but here the transition areas to the free outer edges 6a and 5a are shown diverging, in FIG. 15 there is a converging course.
  • 16 to 19 show variations of the internal gas flow paths.
  • 16 shows a bellows-widening inflow space designated 17 for the gas before entering the gas outlet channels 8.
  • FIG. 17 shows an essentially parallel gas flow path 17 ′.
  • 18 shows an area 17 ′′ widening from the inside out, which is brought about by a gas guide or deflection body 18 in the interior of the burner.
  • a further baffle insert 18 ' is shown in FIG. 19, which in particular optimizes the formation of secondary flames.
  • FIG. 20 A further exemplary embodiment of the invention is shown in FIG. 20, the parts that are otherwise the same relative to FIG. 1 being given the same reference numerals, supplemented by a "c".
  • the injector 20c is fixed on the stand 2c by means of a clamping ring 21, wherein the plug-in attachment 4c can be fixed on the plate of the hob 3c at the same time with the clamping ring 21.
  • the burner is made of three parts from the elements 5c burner ring and 6c burner cover, since an intermediate disk 19 which also provides the flow edge for the gas flame is provided in the front edge region of the burner cover 6c.
  • baffle and guide bodies in their cross-sectional shapes also represent examples, such as the designs of the flow guide cone 7, the cooling fins 16 or the special cross-sectional and profile shapes of the channels 8.
