Description

Dampfkesselfeuerung mit zentrisch angeordneter, von ringförmigen Rauchgasabzügen und Ringkammern für den Wasserumlauf umgebener Zündkammer Die Erfindung betrifft eine Dampfkesselfeuerung mit zentrisch angeordneter, von ringförmigen Rauchabzügen und Ringkammern für den Wasserumlauf umgebener Zündkammer, in welche flüssige oder staubförmige Brennstoffe, mit Verbrennungsluft gemischt, durch eine Öffnung der einen Stirnwand eingeleitet werden.Steam boiler firing with centrally arranged, ring-shaped flue gas outlets and ring chambers for the water circulation surrounded ignition chamber The invention relates a steam boiler with centrally arranged, ring-shaped smoke outlets and ring chambers for the water circulation surrounded ignition chamber, in which liquid or pulverulent fuel, mixed with combustion air, through an opening of the an end wall can be initiated.

Von den bekannten Einrichtungen dieser Art, bei denen die Entzündung des Brennstofluftgemisches im allgemeinen durch an der Einlaßöftnung dieses Gemisches parallel oder quer zu dessen Strömungsrichtung angeordnete elektrische Zündkerzen erfolgt, unterscheidet sich die neue Feuerung dadurch, daß die zur Brennstoffzündung dienende Zündkerze in der der Brennstoffeintrittsöffnung gegenüberliegenden, wasser- oder dampfgekühlten Stirnwand der Zündkammer angeordnet ist. Durch diesen neuartigen Einbau der Kerze in einer gekühlten Wand wird ihr vorzeitiges Verschmoren: verhütet.Of the known bodies of this type in which the inflammation of the fuel-air mixture generally through at the inlet opening of this mixture electrical spark plugs arranged parallel or transversely to its flow direction takes place, the new furnace differs in that that for fuel ignition serving spark plug in the water- or steam-cooled end wall of the ignition chamber is arranged. Through this novel If the candle is installed in a chilled wall, premature scorching is prevented.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch dargestellt, und zwar zeigt: Abb. i den mit zentrischer Zündkammer versehenen Dampfkessel im Längsschnitt und Abb. 2 denselben im Querschnitt.The drawing shows an exemplary embodiment of the subject matter of the invention shown schematically, namely: Fig. i the one provided with a central ignition chamber Steam boiler in longitudinal section and Fig. 2 the same in cross section.

Der Dampfkessel enthält drei ringförmige Wasserkammern i, 2, 3, von denen jede .einzelne von zwei gleichachsigen Zylindern q., 6 bzw. 7, g und i o, 12 begrenzt und durch eine zwischen diesen angeordnete Ringwand' 5 bzw. 8 und i i in zwei nur an einem Ende verbundene Abteilungen unterteilt ist. Die die Kammern einschließenden Zylinderwände sind ebenso wie die Trennwände mit Rippen versehen und so ausgebildet, daß zwischen den einzelnen Wasserkammern lingförmige Abzugskanäle 15, 16 für die Heizgase verbleiben.The steam boiler contains three ring-shaped water chambers i, 2, 3, each of which is delimited by two coaxial cylinders q., 6 and 7, g and io, 1 2 and by an annular wall '5 or 8 and ii arranged between them is divided into two compartments connected only at one end. The cylinder walls enclosing the chambers, like the partition walls, are provided with ribs and are designed in such a way that elongated discharge ducts 15, 16 for the heating gases remain between the individual water chambers.

In den von der inneren Wasserkammer 3 umschlossenen Zylinderraum ragt eine durch einen feuerfesten Zylinder 18 gebildete Zündkammer 13 hinein, deren Durchmesser so gewählt ist, daß um sie herum eine ringförmige Brennkammer i ¢ entsteht. Die äußeren Zylinderwände q. sind im Abstand von einem Mantel i9 umschlossen und begrenzen mit diesem einen mit Austrittsöffnungen 22 versehenen äußeren Rauchgasabzugskanali7.In the cylinder space enclosed by the inner water chamber 3 protrudes an ignition chamber 13 formed by a refractory cylinder 18, the diameter of which is chosen so that an annular combustion chamber i ¢ arises around it. the outer cylinder walls q. are enclosed and bounded at a distance by a jacket i9 with this one provided with outlet openings 22 outer Rauchgasabzugskanali7.

Eine elektrische Zündkerze 2i, die zur Entzündung des Brennstoffes dient, ist in die dem Brennstoffeinlaß 2o der Zündkammer 13 gegenüberliegende Stirnwand der Brennkammer 14 eingebaut. In diese Stirnwand erstreckt sich die ringförmige Wasserkammer 3 und sorgt so für deren hinreichende Kühlung, so daß ein vorzeitiges Verschmoren der Zündkerze ausgeschlossen ist. Die Wirkungsweise des neuen Kessels ist folgende: Ein Gemisch von Luft und zerstäubtem flüssigem oder festem Brennstoff wird. bei 2o in die Zündkammer 13 eingeführt und nur zum Betriebsbeginn mittels der Zündkerze 21 entzündet. Die Verbrennung geschieht alsdann in der Ringkammer 1q., ,aus der die Heizgase unter Abgabe ihrer Wärme durch die Kammern 15, 16 und 1 7 abziehen, um ,aus den Stutzen 22 auszutreten.An electric spark plug 2i, which is used to ignite the fuel, is installed in the end wall of the combustion chamber 14 opposite the fuel inlet 2o of the ignition chamber 13. The annular water chamber 3 extends into this end wall and thus ensures that it is adequately cooled so that premature scorching of the spark plug is excluded. The new boiler works as follows: A mixture of air and atomized liquid or solid fuel is created. Introduced into ignition chamber 13 at 2o and ignited by spark plug 21 only at the start of operation. The combustion then takes place in the annular chamber 1q.

Das Speisewasser wird bei 23 in die äußere Abteilung der Wasserkammer I gedrückt, durchfließt dann die innere Abteilung dieser Kammer, tritt durch das Verbindungsrohr 2¢ in die äußere Abteilung der Wasserkammer 2, durchströmt die innere Abteilung dieser Kammer, tritt durch das Verbindungsrohr 25 und die äußere Abteilung der Wasserkammer 3 und verläßt nach Durchströmung der inneren Abteilung dieser Kammer den Kessel bei 26 als überhitzter Dampf. Selbstverständlich könnte der Wasserumlauf auch anders geschehen, z. $. von der Kammer 1 zur Kammer 3 und dann erst zur Kammer 2.The feed water is at 23 in the outer compartment of the water chamber I pressed, then flows through the inner compartment of this chamber, enters through the Connection pipe 2 ¢ in the outer compartment of the water chamber 2, flows through the inner one Division of this chamber, enters through the connecting pipe 25 and the outer division the water chamber 3 and leaves after flow through the inner department of this chamber the boiler at 26 as superheated steam. Of course, the water circulation could also happen differently, z. $. from chamber 1 to chamber 3 and only then to chamber 2.
