Description
KAISERLICHESIMPERIAL
Das unregelmäßige und damit unvortheilhafte Brennen der Heizflammen von Gasbrennern für Kochzwecke, sowie das Zurückschlagen der Flamme wird meist dadurch verursacht, dafs entweder die Mischung von Gas und Luft keine gleichmäfsige ist oder dafs ein freier, gleichmä'fsig vertheilter Austritt des Gasluftgemisches gehindert ist.The irregular and therefore unfavorable burning of the heating flames of gas burners for cooking purposes, as well as the flashing back of the flame is usually caused by that either the mixture of gas and air is not a uniform one, or that there is a free, evenly distributed outlet of the Gas air mixture is prevented.
Durch den Gegenstand vorliegender Neuerung wird nun behufs Erzielung einer zweckgemäfs brennenden Heizflamme bezweckt und erreicht, eine innige Mischung von Gas und Luft unter gleichmä'fsiger Vertheilung ausströmen zu lassen. Hierzu dienen im Wesentlichen schraubenförmig oder ähnlich gewundene Leit- bezw. Vertheilungsflächen in dem vom Gasluftgemisch durchströmten Hohlraum des Brenners.Through the subject of the present innovation is now for the purpose of achieving an appropriate A burning heating flame aims and achieves an intimate mixture of gas and air with uniform distribution allow. This is done essentially in a helical or similar manner Leit- resp. Distribution surfaces in the cavity of the through which the gas-air mixture flows Burner.
Es können z. B., wie in der beiliegenden Zeichnung im senkrechten Schnitt durch einen Gaskochbrenner veranschaulicht, in der Nähe der ringförmigen Austrittsöffnung c schraubenförmig gewundene Vertheilungs- und Mischflächen α angeordnet sein. Die Form dieser . Flächen α kann, wie beispielsweise aus den in Fig. 2 und 3 gezeichneten Querschnitten ersichtlich, eine beliebige sein. ■It can e.g. B., as illustrated in the accompanying drawing in vertical section through a gas burner, in the vicinity of the annular outlet opening c helically wound distribution and mixing surfaces α be arranged. The shape of this. Areas α can, as can be seen, for example, from the cross-sections drawn in FIGS. 2 and 3, be any. ■
Aufserdem können auch an sonstigen Stellen des vom Gasluftgemisch durchströmten Hohlraumes e des Brenners schraubenförmig oder ähnlich gewundene Flächen, z. B. in Form einer centralen Mischschnecke b (Fig". 1) angeordnet \yerden, wodurch die Wirkung erzielt wird, dem Gasluftgemisch infolge der entstehenden wirbelnden Bewegung eine gleichmäfsige Vertheilung zu geben.In addition, at other points of the cavity e of the burner through which the gas-air mixture flows, helical or similarly wound surfaces, e.g. B. in the form of a central mixing screw b (Fig ". 1) arranged \ yerden, whereby the effect is achieved of giving the gas-air mixture due to the resulting whirling movement a uniform distribution.
Der in der Nähe der Austrittsöffnungen c vorgesehene Kegel α mit Leitflächen hat insbesondere den Zweck, das Gasluftgemisch regelmäfsig vertheilt und gemischt der Brennstelle c zuzuführen. Natürlich können auch an den Wandungen des vom Gasluftgemisch durchströmten Hohlraumes e geeignete, dem bezeichneten Zweck dienende Leit- und Mischflächen vorgesehen sein.The cone α with guide surfaces provided in the vicinity of the outlet openings c has the particular purpose of supplying the gas-air mixture regularly distributed and mixed to the combustion point c . Of course, suitable guide and mixing surfaces serving the designated purpose can also be provided on the walls of the cavity e through which the gas-air mixture flows.
Ebenso erreicht man durch die im Grundrifs wellenförmige Umrifsform der Deckplatte f (Fig. 4) und eventuell auch des oberen Theiles des Brennergehäuses, deren einzelne Wellenberge und -thäler den Vorsprüngen bezw. Vertiefungen des Kegels α entsprechend angeordnet sind, einen regelmäfsig vertheilten Austritt des aus lauter gleichen Einzelströmen zusammengesetzten Gasluftstromes, der somit eine gleichmäfsige ringförmige Flamme ergiebt.The shape of the cover plate f (Fig. 4) and possibly also of the upper part of the burner housing, the individual wave crests and holers of which the projections resp. Depressions of the cone α are arranged accordingly, a regularly distributed outlet of the gas air stream composed of nothing but equal individual streams, which thus results in a uniform ring-shaped flame.
Während bei den bisher bekannten Brennern ein unregelmäfsiges Anstofsen und Zurückprallen des Gasluftstromes, besonders an der oberen, den Hohlraum e abdeckenden Platte f, stattfand und dadurch einem ungleichmäfsigen Austreten des Gases und einem Zurückschlagen" der Flamme Vorschub geleistet wurde, findet infolge der Anordnung der neuen Misch- und Vertheilungsflächen eine regelrechte Leitung des gleichmäfsig vertheilten Gasluftgemisches auf seinem Wege durch den Hohlraum e statt. Hierdurch wird nach angestellten Versuchen eine sehr ruhige gleichmäfsige FlammenbildungWhile with the burners known up to now there was an irregular attack and rebounding of the gas air flow, especially on the upper plate f covering the cavity e , which promoted an uneven discharge of the gas and a flashback "of the flame," as a result of the arrangement of the new Mixing and distribution surfaces, a regular conduction of the evenly distributed gas-air mixture takes place on its way through the cavity E. This results in a very calm, even flame formation according to experiments
