Description

Gasbrenner mit Mischkammer, in die das eine mittel axial, das andere Mittel tangential einströmt Um eine innige Mischung von Brenngas und Luft und dadurch eine möglichst vollkommene Verbrennung zu erzielen, sind Gasbrermer vorgeschlagen worden, bei denen das eine Mittel axial, das andere Mittel tangential in eine Mischkammer einströmt. Diese bekannten Brenner haben aber trotz dieser die innige Mischung beider Mittel begünstigenden Anordnung den Fehler, daß die beiden Mittel, je nach der Beanspruchung des Brenners, mit veränderlicher, nur bei einem bestimmten Belastungsgrad günstigen Geschwindigkeit in der Mischkammer zusammentreffen, so daß keine-innige Mischung erzielt wird, weil die Geschwindigkeiten meist zu klein sind. Dies rührt davon her, daß die Mittel zur Regelung der Gas- und Luftmengen in solchen Abständen vorn der Mischkammer angeordnet sind, daß die den Gasen in den Regelvorrichtungen verteilten Geschwindigkeiten bis zur Mischstelle sich erheblich vermindern, weil diese Leitungsquerschnitte den größten Mengen entsprechen. Damit sind auch Druckverluste verbunden, und eine gute Verbnennung bei jedem Belastungsgrad istmit solchen Brennern trotz Wirbelwirkung. nicht zu erreichen.Gas burner with mixing chamber, in one central axial, the other Medium flows in tangentially around an intimate mixture of fuel gas and air and thereby To achieve as perfect a combustion as possible, gas burners are proposed in which one means axially, the other means tangentially into a mixing chamber flows in. In spite of this, however, these known burners have an intimate mixture of both Means favoring arrangement the error that the two means, depending on the stress of the burner, with variable, favorable only with a certain degree of load Speed meet in the mixing chamber, so that no intimate mixing is achieved because the speeds are usually too low. This is because that the means for regulating the gas and air quantities at such intervals in front of the Mixing chambers are arranged that the gases distributed in the control devices The speeds up to the mixing point are considerably reduced because these line cross-sections correspond to the largest quantities. This is also associated with pressure losses, and a Good connection with any degree of exposure is with such burners in spite of the vortex effect. unavailable.

Die Erfindung vermeidet diese Nachteile dadurch, daß die Mittel zur Regelung von Gas und Luft unmittelbar an der Mischkammer angebracht sind. Es tritt die. Luft durch Stutzen a, das Gas durch Stutzen b und feste Schlitze e in das Mischgehäuse f ein. Die Luftmenge wird durch ,eine verstellbare Klappe c derart eingeregelt, daß bei gleichbleibendem Vordruck, selbst bei geringer Belastung, stets die gleiche Austrittsgeschwindigkeit, nämlich die dem Druckunterschied entsprechende, beibehalten werden kann. Ebenso werden für das Gas die ,Querschnitte der Austrittsschlitze e durch einen verstellbaren Reelschieberd verändert, der diese überdeckt. Gas und Luft von gleichbleibendem Vordruck erhalten so bei den verschiedensten Belastungen stets die gleichen, dem Druckunterschied entsprechenden Ausströmungsgeschwindigkeiten, die weiterhin auch noch dauernd in ein bestimmtes Verhältnis zueinander eingeregelt werden können.The invention avoids these disadvantages in that the means for regulating gas and air are attached directly to the mixing chamber. It occurs. Air through nozzle a, the gas through nozzle b and fixed slots e into the mixer housing f. The amount of air is regulated by an adjustable flap c in such a way that the same exit speed, namely the one corresponding to the pressure difference, can always be maintained with a constant pre-pressure, even with a low load. Likewise, the cross-sections of the outlet slots e for the gas are changed by an adjustable slide valve that covers them. Gas and air with a constant pre-pressure always receive the same outflow velocities corresponding to the pressure difference under the most varied of loads, which can also be continuously regulated in a certain ratio to one another.

Schließlich können noch die Regelklappe c und der Schieberd zwang-läufig miteinander derart verbunden werden, daß die Verstellung der zugehörigen Querschnitte entsprechend der Belastung gleichzeitig erfolgt unddauernd die wirksamsten Mischgeschwindigkeiten erzielt werden.Finally, the control flap c and the slide d can also be used are connected to each other in such a way that the adjustment of the associated cross-sections depending on the load, the most effective mixing speeds occur at the same time and continuously be achieved.
