Description

Kammerwasserrohrkessel mit einzelnen Wasserrohrgruppen. Die Erfindung bezieht sich auf Kammerwasserrohrkessel mit einzelnen Wasserrohrgruppen und besteht im wesentlichen darin, daß die unmittelbar über der Feuerung liegende Wasserrohrgruppe am tiefsten und in einem größeren Abstande von der Stirnwand der Kesseleinmauerung angeordnet ist, währen die seitlichen Rohrgruppen staffelweise höher und der Stirnwand der Einmauerung näher liegen.Chamber water tube boilers with individual water tube groups. The invention refers to aqueous tube boilers with individual water tube groups and consists essentially in the fact that the water pipe group immediately above the furnace deepest and at a greater distance from the front wall of the boiler wall is arranged, while the side tube groups are staggered higher and the end wall closer to the walling.

Die Abb. i und a der ein Ausführungsbeispiel der Erfindung veranschaulichenden Zeichnung stellen den neuen Dampferzeuger im Längsschnitt bzw. Querschnitt dar.Figs. I and a of the illustrative embodiment of the invention Drawings show the new steam generator in longitudinal section or cross-section.

Die Wasserrohre des Kessels sind, wie die Zeichnung zeigt, in drei Gruppen a, b und c von Längsrohren geteilt, von denen . die mittlere Gruppe c tiefer liegt als die beiden seitlichen Rohrgruppen a, b. Die vorderen Endkammern der mittleren Wasserrohrgruppe c sind in einem größeren Abstand von der Stirnwand der Kesseleinmauerung angeordnet als die Endkammern der beiden seitlichen Wasserrohrgruppen a, b. Oberhalb der mittleren Wasserrohrgruppe c und zwischen den beiden seitlichen Rohrgruppen a, b ist der trberhitzer,d angeordnet. Nachdem die Rauchgase die Wasserrohre der Gruppen a, b, c und den unmittelbar über der mittleren Rohrgruppe c und zwischen den höherliegenlden Rohrgruppen a und b angeordneten Überhitzer d umspült haben, gelangen sie zu einem nachgeschalteten Steilrohrkessel f.The water pipes of the boiler are, as the drawing shows, divided into three groups a, b and c of longitudinal pipes, of which. the middle group c is lower than the two lateral tube groups a, b. The front end chambers of the central water pipe group c are arranged at a greater distance from the end wall of the boiler walling than the end chambers of the two lateral water pipe groups a, b. Above the middle water pipe group c and between the two side pipe groups a, b is the turbo heater, d. After the flue gases have washed around the water pipes of groups a, b, c and the superheater d located directly above the middle pipe group c and between the higher-lying pipe groups a and b , they reach a downstream steep-tube boiler f.

Die Wasserrohre der Gruppe a,.b,c können in bekannter Art mit einem Oberkessel oder aber, wie die Zeichnung zeigt, einerseits mit einem Dampfsammler m und anderseits mit dem nachgeschalteten Steilrohrkessel 1 ver- Bunden sein. Die Speisung erfolgt mittels der Speiseleitung g in den Steilrohrkessel f, und erst aus diesem gelangt das Speisewasser in die Rohrgruppen a, b, c des Hauptkessels.The water pipes of group a, .b, c can be connected in a known manner with an upper boiler or, as the drawing shows, on the one hand with a steam collector m and on the other hand with the vertical tube boiler 1 connected downstream. The feed takes place by means of the feed line g into the steep tube boiler f, and only from this does the feed water get into the tube groups a, b, c of the main boiler.

Die Erfindung ermöglicht es, die Kesselheizfläche über dem Rost auch dann wirksam unterzubringen, wenn dieser sehr kleine Abmessungen erhält. Weiter wird durch diese Anordnung der natürliche Umlauf des Kesselwassers gefördert, da die vorderen Endkammern der mittleren Wasserrohrgruppe c von den Heizgasen kräftiger bestrichen und beheizt werden, als wenn sie in der gleichen Ebene wie die Endkammern der seitlichen Rohrgruppen a, b lägen. In der mittleren'Rohrgruppe c wird daher eine raschere Verdampfung erzielt als in den beiden seitlichen Rohrgruppen a, b. Die am meisten beanspruchte mittlere Rohrgruppe c ist von der Stirnseite des Kessels her gut zugänglich und kann bei Beschädigungen leicht ausgebessert oder ersetzt werden. Ein weiterer Vorteil besteht darin, daß der überhitzer d oberhalb der mittleren und zwischen den beiden seitlichen Wasserrohrgruppen sehr günstig untergebracht werden kann, und zwar sowohl hinsichtlich der Ausnutzung des Raumes als auch des Brennstoffes.The invention makes it possible to accommodate the boiler heating surface effectively above the grate even if it is given very small dimensions. This arrangement also promotes the natural circulation of the boiler water, since the front end chambers of the central water pipe group c are more strongly coated and heated by the heating gases than if they were in the same plane as the end chambers of the side pipe groups a, b . In the middle pipe group c, therefore, more rapid evaporation is achieved than in the two lateral pipe groups a, b. The most stressed middle pipe group c is easily accessible from the front of the boiler and can easily be repaired or replaced if it is damaged. Another advantage is that the superheater d can be accommodated very inexpensively above the central and between the two lateral water pipe groups, both with regard to the utilization of the space and the fuel.
