Description
Rauchgasvorwärmer. Im Hauptpatent 426928 ist ein Rauohgasvorwärmer beschrieben, dessen, wagerecht gelagerten Rohre mit angegossenen, zur Längsachse senkrechten, quadratischen Rippen verstehen sind, die.geschlossene Wände als Leitflächen für die Rauchgase ergeben.. Diese Wände bilden geradlinige Kanäle für die Gase. Die Erfindung ihat eine Verbesserung dieses Vorwärmers zum Gegenstand. Die Verbesserung besteht darin;, daß die quadratischen Rippen nicht senkrecht, sondern schräg zur Längsachse der Röhren stehen. Die schrägen Rippen. bilde. beim Zusammenbauen der Rohre zickzackartige Leitflächen für die Gase, woraus sich mehrere Vorteile ergeben. Die Gase erfahren nämlich durch das, Anprallen gegen die schrägen Flächenteile eine dauernde Durchwirbelung, so daß eine gleichmäßige Wärmeentziehung erfolgt. überdies wird. durch die Schrägstellung der Rippen eine Vergrößerung ihrer Fläche ermöglicht. Versuche haben gezeigt, daß bereits eine geringe Schrägstellung der Rippen eine erhebliche Verbesserung des Wirkungsgrades des Vorwärmers zur Folge hat. Der Erfindungsgegenstand ist in der Zeichnung in einer Ausführungsform dargestellt.Flue gas preheater. The main patent 426928 is a raw gas preheater described, whose, horizontally stored pipes with cast, to the longitudinal axis vertical, square ribs are to be understood, the closed walls as guide surfaces for the flue gases .. These walls form straight channels for the gases. The object of the invention is to improve this preheater. The improvement consists in the fact that the square ribs are not perpendicular, but oblique to the Stand the longitudinal axis of the tubes. The sloping ribs. form. when assembling the Pipes zigzag baffles for the gases, resulting in several advantages. The gases experience namely through the impact against the sloping surface parts a constant turbulence, so that a uniform heat extraction takes place. moreover will. the inclined position of the ribs enables their area to be enlarged. Tests have shown that even a slight inclination of the ribs a results in a significant improvement in the efficiency of the preheater. The subject of the invention is shown in the drawing in one embodiment.
Abb. r und 2 stellen ein Vorwärmerrohr mit schrägen Rippen im Längs- und Querschnitt dar.Fig. R and 2 show a preheater pipe with inclined ribs in the longitudinal and cross-section.
Abb. 3 veranschaulicht, wie die Rohre zwecks Bildung der ziekzackartigen Kanäle zusammengebaut werden.Fig. 3 illustrates how the tubes are used to form the ziezag Channels to be assembled.
Der in Abb. 3 eingezeichnete Pfeil zeigt, wie die Rauchgase mehrfach von ihrem geraden Wege abgelenkt werden. Ferner erkennt man, daß sämtliche Rohre des Vorwänners einander gleich sind und nur durch-entsprechendes Versetzen gegeneinander die Zickzackform der Kanäle ergeben.The arrow drawn in Fig. 3 shows how the smoke gases multiply be distracted from their straight path. It can also be seen that all pipes of the forerunner are equal to each other and only by corresponding offset against each other result in the zigzag shape of the channels.
