Description

Die Erfindung betrifft einen Rauchgasv orwärmer für Dampf- und Heizkessel und besteht in Lamellen aus Blech, die zu einem Bündel vereinigt durch Traversen und Zuganker zusammengehalten in den Zug des Kraft oder Heizkessels gestellt und mit dem Speiserohr des Kessels oder bei Hdizkessel mit dem R'üicklauf der Dampf- oder Warmwasserheizung verbunden werden.The invention relates to a Rauchgasv preheater for steam and heating boilers and consists of lamellas made of sheet metal, which are united in a bundle by trusses and tie rods held together and placed in the train of the power or boiler with the feed pipe of the boiler or with Hdizkessel with the return of the steam or hot water heating.

Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgedankens, und zwar Abb. i ein Schaltschema des Rauchgasvorwärmers an einem Zweiflammrohrkessel, Abb. z die Art des Zusammenbaus der Heizplatten auf dem Zu- bzw. Ableitungsrohr.The drawing shows an embodiment of the inventive concept, namely Fig. i a circuit diagram of the flue gas preheater on a two-flame tube boiler, Fig. Z the type of assembly of the heating plates on the inlet and outlet pipe.

Die Lamellen des Vorwärmers liegen senkrecht im Fuchs mit einem Abstand für den Durchgang der Rauchgase. Die Lamellen sind verzinkt und sind auf einem Zu- und Ableitungsrohr aufgereiht, und zwar sitzt die Lamelle so auf dem Rohr, daß Öffnungen eines inneren Distanzringes b mit gleichen Öffnungen des Rohres c übereinstimmen. Um aber die Lamellen oder Taschen a zusammenziehen zu können, wird bei dem Aufreihen zwischen je zwei Lamellen a ein Abstandsring d mit zwei Asbestdichtungen gelegt, worauf durch Ankerschrauben das Ganze zusammengezogen wird. Jetzt kann das Wasser bei e ein- und bei f austreten, um einer Kreiselpumpe g zuzufließen, die es in den Dampfkessel pumpt.The lamellas of the preheater are vertical in the fox with a distance for the passage of the flue gases. The lamellas are galvanized and are lined up on an inlet and outlet pipe, and the lamella sits on the pipe in such a way that openings of an inner spacer ring b coincide with the same openings in the pipe c. However, in order to be able to pull the slats or pockets a together, a spacer ring d with two asbestos seals is placed between each two slats a, whereupon the whole thing is pulled together by means of anchor bolts. The water can now enter at e and exit at f to flow to a centrifugal pump g, which pumps it into the steam boiler.

Bei .Anwendung der Erfindung für Heizkessel erfolgt ebenfalls der Einbau in den Fuchs, jedoch in den Rücklauf des Wassers, so daß beispielsweise Wasser von 40° jetzt auf 7o bis 8o° aufgewärmt in den Kessel kommt, was eine erhebliche Koksersparnis bedeutet.In .Application of the invention for boilers also takes place Installation in the fox, but in the return of the water, so that for example water from 40 ° now to 7o to 8o ° is warmed up in the boiler, which is a considerable Saving coke means.

Die Heizgase strömen zwischen den Lamellen des Rauchgasvorwärmers, so daß der Wärmeinhalt restlos übergehen kann. Die Asche kann senkrecht herunterfallen, so daß - kaum eine äußere Verunreinigung von den Gasen eintritt. Neu ist ferner, daß die Lamellen verzinkt werden, wodurch nicht nur eine Oxydation der Lamellen unterbunden, sondern auch der Wärmeübergang bedeutend gefördert wird.The heating gases flow between the fins of the flue gas preheater, so that the heat content can pass over completely. The ashes can fall straight down, so that - hardly any external contamination from the gases occurs. What is also new is that the lamellas are galvanized, which not only results in an oxidation of the lamellas prevented, but also the heat transfer is promoted significantly.

Außerdem ist neu, daß die abgehende Heißwasserleitung mit einer Kaltwasserleitung verbunden wird. Das Absperrventil wird dann gering geöffnet, wenn das Heißwasser über ioo° warm werden und von der Pumpe nicht mehr angenommen werden sollte.In addition, it is new that the outgoing hot water pipe is connected to a cold water pipe connected. The shut-off valve is then opened slightly when the hot water heat up to over 100 ° and should no longer be accepted by the pump.

Das Kaltwasser kann im Inneren der Lamellen Stein absetzen, den man leicht abklopfen und durch die Öffnung der Lamellenverbindung entfernen kann, wozu es notwendig ist, die Ankerschrauben zu lösen.The cold water can deposit stone inside the lamellas, which one can can be easily knocked off and removed through the opening of the lamellar connection, for which purpose it is necessary to loosen the anchor bolts.
