Description
Vorrichtung zur Erzeugung von Heizgasen Die Erfindung betrifft eine Vorrichtung zur Erzeugung von Heizgasen durch Verbrennung flüssiger öder gasförmiger Brennstoffe in einem Luftstrom, bei welcher die Brennkammer von mehreren konzentrischen: Ringräumen umgeben ist, die ganz oder teilweise hintereinandergeschaltet sind. Bei den bekannten Vorrichtungen dieser Art erfolgt die Regelung der Luftzufuhr durch eine einfache Drosselklappe in der Luftzuleitung. Damit kann aber eine Regelung der Luftverteilung auf die einzelnen Ringräume nicht erreicht werden.Apparatus for generating heating gases The invention relates to a Device for generating heating gases by burning liquid or gaseous Fuels in an air stream in which the combustion chamber consists of several concentric: Annular spaces is surrounded, which are wholly or partially connected in series. at the known devices of this type are controlled by the air supply a simple throttle valve in the air supply line. But this can be a regulation the air distribution to the individual annular spaces cannot be achieved.
Erfindungsgemäß ist daher vor der Brennkammer und den bleichachsigen Ringräumen eine mit veränderlichen Öffnungen versehene drehbare Verstellscheibe angebracht, um den Durchtritt der Luft in Anpassung an die jeweils vorhandenen Betriebsverhältnisse zu regeln.According to the invention is therefore in front of the combustion chamber and the pale-axis Annular spaces a rotatable adjusting disk provided with variable openings attached to the passage of air in adaptation to the existing operating conditions to regulate.
In der Zeichnung ist eine Vorrichtung zur Erzeugung von Heizgasen beispielsweise dargestellt. Durch das Rohr r strömt die Luft der Brennkammer zu. Sie verteilt sieh in dem Vorraum 2 auf den. Brennraum 3 und auf die beispielsweise zu zweit um den Brennraum gelegten Ringräume q. und 5. Die Ringräume können gleich oder .verschieden groß sein: Der aus einem hochhitzebeständigen Baustoff gebildete Brennraum 3 ist ganz dünnwandig ausgeführt und nur mit Rücksicht auf eine gewisse Stefigkeit infolge der Belastung durch das Eigengewicht bemessen, da auch bei Druckluftbetrieb innere Überdrücke nicht aufzunehmen sind. Die in den Zwischenräumen und 5 entlang streichende Luft kühlt jeweils die innenliegende Wandung und erwärmt sich dabei selbst, so daß in dem Rauire 7 eine innige 1Zischüng zwischen den verschiedenen Gasströmen leichter möglich ist.In the drawing is a device for generating heating gases for example shown. The air flows through the pipe r to the combustion chamber. You see distributed in the anteroom 2 on the. Combustion chamber 3 and the example Annular spaces placed in twos around the combustion chamber q. and 5. The annulus can be the same or .different sizes: The one made of a highly heat-resistant building material Combustion chamber 3 is designed to be very thin-walled and only with a certain degree of consideration Stiffness measured as a result of the load caused by its own weight, as this is also the case with compressed air operation internal overpressures are not to be absorbed. The ones in the spaces and 5 along Brushing air cools the inner wall and warms up in the process himself, so that in the room 7 there was an intimate discussion between the different Gas flows are easier possible.
Um die Vermischung der verschieden erwärinten Gase zu unterstützen, sind die Wände mit konischen Endstücken 8, auf denen weitere Führungs-, Wirbelbleche oder Öffnungen angeordnet sein können, versehen. -Auch können die zylindrischen Teile mit derartigen Hilfsvorrichtungen bereits versehen werden. Die Stützen 9 und ro sind, in der Stromrichtung gesehen, schräg gestellt oder so ausgebildet, daß sie Stücke einer Schraubenlinie sind, so daß eine kreisende Bewegung der Kühlluft erzielt wird. Die die Zwischenräume bildenden Wandungen Ir und 1a werden zweckmäßigerweise aus blank bleibenden Baustoffen hergestellt, damit die Strahlungswärme möglichst herabgesetzt. wird.To support the mixing of the differently heated gases, are the walls with conical end pieces 8, on which more guide, vortex plates or openings can be arranged. -Also can be cylindrical Parts are already provided with such auxiliary devices. The supports 9 and ro are, seen in the direction of flow, inclined or designed so that they are pieces of a helix, causing a circular motion of the cooling air is achieved. The walls Ir and 1a forming the spaces are expediently Made from building materials that remain bare, so that the radiant heat as possible degraded. will.
Die veränderliche Verteilung der verschiedenen Gasströme auf die verschiedenen Räume wird erfindungsgemäß durch eine mit verschiedenen Öffnungen versehene Verstellscheibe 13 erreicht, die durch eine Vorrichtung beliebiger Art, beispielsweise mittels eines Handgriffes 14, von außen betätigt werden kann. Der durch die Leitung 15 zugeführte Brennstoff wird erstmalig durch eine künstliche Zündvorrichtung 16 zur Zündung gebracht.The variable distribution of the different gas flows to the different rooms is achieved according to the invention by an adjusting disk 13 provided with different openings, which can be operated from the outside by a device of any type, for example by means of a handle 14. The fuel supplied through line 15 is ignited for the first time by an artificial ignition device 16.
Unter Umständen kann es zweckmäßig sein; die Kühlluft ganz oder teilweise höher vorzuwärmen, als es auf der einfachen Länge des Lufterhitzers möglich ist. In diesem Fall wird die gesamte oder ein Teil der Kühlluft durch einen Teil oder durch alle Ringräume nacheinander geleitet, und zwar ain zweckmäßigsten im Gegenstrom. Die Luft durchströmt dann erst den äußeren Ringraum, dann nacheinander die inneren und schließlich die Brennkammer.It may be useful under certain circumstances; the cooling air in whole or in part preheat higher than is possible with the simple length of the air heater. In this case, all or part of the cooling air is through part or passed through all the annular spaces one after the other, most expediently in countercurrent. The air then first flows through the outer annular space, then one after the other through the inner ones and finally the combustion chamber.
