Description

Flammrohrkessel mit das Flammrohr durchgreifenden Siederohren Die Erfindung betrifft einen Flammrohrkessel mit das Flammrohr durchgreifenden Siederohren und zwischen den Siederohren zur Bildung in der Längsrichtung hin und her gehender Rauchgaswege eingeschalteten Längsführungswänden.Flame tube boiler with boiler tubes extending through the flame tube The invention relates to a flame tube boiler with boiler tubes extending through the flame tube and reciprocating between the boiler tubes for formation in the longitudinal direction Flue gas paths switched on longitudinal guide walls.

Bei verschiedenen anderen Kesselbauarten ist bereits versucht worden, den Einlaßstutzen für das Speisewasser mit Siederöhren in Verbindung zu bringen, so daß die Siederohre als Vorwärmer dienen. So hat man beispielsweise bei Feuerbuchsen in Lokomotivkesseln das Speisewasser unmittelbar in die von der Feuerung unmittelbar beheizten Heizflächen eingeführt. Andererseits hat man auch bereits getrennte Wasservorwärmer in den hinteren Kesselteil eingebaut, die Jedoch mit dem Dampfkessel nur teilweise in Berührung kamen.Attempts have already been made in various other boiler types to bring the inlet nozzle for the feed water into connection with boiler pipes, so that the boiler pipes serve as preheaters. This is the case with fire boxes, for example in locomotive boilers the feed water directly into that of the furnace heated heating surfaces introduced. On the other hand, you already have separate water preheaters Built into the rear part of the boiler, but only partially with the steam boiler came into contact.

Erfindungsgemäß soll nun unter Vermeidung besonderer Apparaturen und Einrichtungen in einfachster Weise bei Flammrohrkesseln mit das Flammrohr durchgreifenden Siederohren und zwischen den Siederohren zur Bildung in der Längsrichtung hin und her gehender Rauchgaswege eingeschalteten Längsführungswänden eine besonders: .günstige Vorwärmung für das Speisewasser geschaffen werden, die gleichzeitig einte höhere Ausnutzung der Rauchgase und einen günstigeren Wirkungsgrad des Kessels ermöglicht, was dadurch erreicht wird, daß der Ein1aßstutzen für das Speisewasser mit den Siederohren des letzten Rauchgasweges in Verbindung steht und so diese Siederohre als Vorwärmer für das Speisewasser dienen.According to the invention, avoiding special apparatus and Facilities in the simplest way for flame tube boilers with the flame tube reaching through Boiler tubes and between the boiler tubes to form in the longitudinal direction and longitudinal guide walls connected to the flue gas paths are particularly: Preheating for the feed water can be created, which at the same time united higher Utilization of the flue gases and a more favorable efficiency of the boiler, which is achieved by the fact that the inlet connection for the feed water with the boiler pipes the last flue gas path is connected and so these boiler pipes as a preheater serve for the feed water.

Auf der Zeichnung ist die Erfindung in schematischer Darstellung an einem Ausführungsbeispiel veranschaulicht und zeigt: Abb. i einen Längsschnitt durch einen Flammxohrkessel, Abb. z einen Querschnitt nach C-D der Abb. i, Abb.3 einen Schnitt nach A-B der Abbildung i.The invention is shown schematically in the drawing an embodiment illustrated and shows: Fig. i a longitudinal section through a Flammxohrkessel, Fig. z a cross-section according to C-D of Fig. i, Fig. 3 a Section according to A-B of Figure i.

Der Flammrohrkessel besteht aus dem eigentlichen Wasserkessela und dem Flammrohr b, in dessen beiden vorderen Stutzen c der Feuerungsrost d angeordnet ist, der von der Beschickungsanlage e bedient wird. Das Flammrohr b ist durch eine möglichst große Anzahl Siederohre f durchs°tzt, welche bündelartig angeordnet sind .und in bekannter Weise schräg gestellt sein können. Die Siederohre, welche den unterhalb des Flammrohres b liegenden Teil des Wasserkessels mit seinem oberhalb liegenden Teil verbinden" haben die Wirkung einer dauernden Umwälzung des Wasserinhalts des Kessels, wodurch eine gleichmäßigere Erhitzung des gesamten Wasserinhalts erzielt wird.The flame tube boiler consists of the actual water boiler and the flame tube b, in whose two front nozzles c the furnace grate d is arranged which is served by the charging system e. The flame tube b is through a as large as possible number of boiler tubes f, which are arranged in bundles . And can be inclined in a known manner. The boil pipes, which the part of the kettle lying below the flame tube b with its above Connect lying part "have the effect of a permanent circulation of the water content of the boiler, which results in a more even heating of the entire water content will.

Zwischen die Siederohre f sind die bekannten Längsscheidewände g und la eingelassen, so daß die Rauchgase auf bestimmten, in der Kessellängsrichtung hin und her gehenden Wegen durch den Kessel bzw. zwischen den Siederohren f durchströmen, bevor sie durch den Auslaßstutzen i abgeführt werden.Between the boiler pipes f are the known longitudinal partitions g and la let in, so that the flue gases on certain, in the boiler longitudinal direction flow back and forth through the boiler or between the boiler pipes f, before they are discharged through the outlet port i.

Der Einlaßstutzen k für das Speisewas-s.er ist gemäß der Erfindung mit den Siederohrenl des letzten Rauchgasweges in Verbindung gebracht, so daß diese Siederohre l als Vorw .ärmer für das Speisewasser dienen. Dadurch, daß bei einem Flammrohrkessel mit Quersiederohren und hin und her gehenden Raucbgaszügen der Speisewassereinla,ßstutzen mit den im letzten Zuge liegenden Siederohren in Verbindung gebracht ist, wird in einfachster Weise eine gute Vorwärmung und gute Ausnutzung der Rauchgase erzielt.The inlet connection k for the feed water is according to the invention associated with the Siederohrenl of the last flue gas path, so that this Boiler pipes serve as a preheater for the feed water. Because with one Flame tube boiler with cross boiler tubes and flue gas flues going back and forth from the feed water inlet is associated with the boiling pipes in the last train, is in the simplest way achieved good preheating and good utilization of the flue gases.
