Description

Verfahren zur Verhütung des Abreißens der Flamme bei geschlossenen Feuerungen. Den Gegenstand der Erfindung bildet ein Verfahren zur Verhütung des Abreißens der Flamme bei mit flüssigen oder gasförmigen Brennstoffen betriebenen geschlossenen Feuerungen.Method of preventing the flame from being torn off when closed Furnaces. The subject of the invention is a method for preventing the Breaking off of the flame in the case of liquid or gaseous fuels closed furnaces.

Beim Arbeiten von durch flüssige oder gasförmige Brennstoffe und Preßluft gespeisten sogenannten geschlossenen Feuerungen, die unmittelbar in dem Raum brennen, in dem die zu erhitzenden oder zu verdampfenden Flüssigkeiten und die daraus entwickelten Dämpfe sich befinden, sei es, daß Flammen als sogenannte Unterwasserflammen unmittelbar in die Flüssigkeiten tauchen oder letztere in Flammen oder heiße Verbrennungsgase eingesprüht werden, tritt bei manchen Betricbsverhältnissen, besonders auch bei stärkeren Druckschwankungen im Arbeitsraume, ein unruhiges und unvollkommenes Brennen und Abreißen der Flamme ein.When working with liquid or gaseous fuels and compressed air so-called closed firing systems that burn directly in the room, in which the liquids to be heated or evaporated and the liquids developed from them There are vapors, be it that flames as so-called underwater flames directly immerse in the liquids or the latter in flames or hot combustion gases are sprayed, occurs in some operational conditions, especially also stronger pressure fluctuations in the work area, restless and imperfect burning and tearing off the flame.

Die Ursache liegt hauptsächlich darin, daß es bei dieser Art Feuerung schwer ist, das Gleichgewicht zwischen der Zündgeschwindigkeit und der Geschwindigkeit des Brenngemischstromes aufrechtzuerhalten, wenn der Entflammungspunkt des Brennstoffes, der Druck der Verbrennungsluft und der Gegendruck im Arbeitsraum wechseln.The main reason for this is that with this type of firing difficult is the balance between the ignition speed and the speed to maintain the fuel mixture flow if the ignition point of the fuel the pressure of the combustion air and the counter pressure in the work area change.

Gemäß der Erfindung wird diese Schwierigkeit dadurch behoben, daß die Grenzen der Entflammbarkeit des Brenngemisches durch Zusätze zu ihm auseinandergezogen werden. Es geschieht dies, indem man dem Brennstoff in der Flamme in Glut geratende brennbare oder nicht brennbare feinkörnige Massenteilchen zumischt, z. B. Schamottepulver durch die Preßluft oder das Preßgas in die Flammen führen läßt. Besonders geeignet für vorliegenden Zweck ist bei mit Ölen betriebenen Innenfeuerungen der Zusatz von fein gemahlener Kohle, Pech o. dgl. zum Öl.According to the invention, this problem is overcome in that the limits of the flammability of the fuel mixture pulled apart by additives to it will. It does this by causing the fuel in the flame to glow admixed flammable or non-flammable fine-grained mass particles, e.g. B. Fireclay powder can lead through the compressed air or the compressed gas in the flames. Particularly suitable For the present purpose, the addition of oil-operated internal firing systems is required finely ground coal, pitch or the like to the oil.

Durch die glühenden Teilchen wird ein Wiederzünders des Brenngasstromes bewirkt, wenn sonst die Flamme abreißen würde, bzw. es wird bei Zugabe brennbarer Massenteilchen ein Abreißen der Flamme dadurch verhütet, daß z. B. die Kohlenteilchen, die andere Brenngeschwindigkeit als Öle verschiedener Zusammensetzung haben, bei Geschwindigkeiten desBreni.gemischstromes Weiterbrennen, bei denen die Ölgasflamme allein schwanken oder abreißen würde.The glowing particles re-ignite the flow of fuel gas causes if the flame would otherwise break off, or it becomes more flammable when added Prevents mass particles from tearing off the flame in that z. B. the coal particles, which have a different burning rate than oils of different compositions Burning speeds of the fuel mixture flow at which the oil gas flame alone would sway or tear off.
