Die Erfindung betrifft einen Heizrohrdampfkessel mit eingebautem Überhitzer, der eine hohe Überhitzung des Dampfes zuläßt und gleichzeitig einfach und leicht zugänglich ist.The invention relates to a heating tube steam boiler with a built-in superheater, the allows high overheating of the steam and at the same time simple and easily accessible is.

Die Erfindung, ist im besonderen für Lokomotivkessel geeignet, kann jedoch auch für Heizrohrkessel anderer Art benutzt werden.
In der Zeichnung ist die Erfindung in Anwendung auf einen Lokomotivkessel dargestellt. ;The invention is particularly suitable for locomotive boilers, but can also be used for heating tube boilers of other types.
In the drawing, the invention is shown in application to a locomotive boiler. ;

Fig. ι ist ein Längsschnitt durch den Kessel. Fig. 2 ist ein Querschnitt der Fig. ι nach der Linie C-C. Fig. 3 ist ein Querschnitt nach der Linie D-D der Fig. 1. Fig. 4 zeigt eine etwas abgeänderte Ausführungsform des Überhitzers.Fig. Ι is a longitudinal section through the boiler. Fig. 2 is a cross section of Fig. Ι along the line CC. Fig. 3 is a cross section along the line DD of Fig. 1. Fig. 4 shows a somewhat modified embodiment of the superheater.

. In der in den Fig. 1, 2 und 3 dargestellten Ausführungsform der Erfindung bezeichnet 1 den Kesselmantel, 2 die Rauchkammer, 3 die Feuerrohre, 4 die zu den Zylindern führenden Dampfrohre und 5 das von dem Dom 6 zu dem Überhitzer führende Dampfrohr. Am Ende des Dampfrohres 5 ist in dem Dom 6 das Drosselventil 7 angeordnet.. In the embodiment of the invention shown in FIGS. 1, 2 and 3, 1 is designated the boiler jacket, 2 the smoke chamber, 3 the fire tubes, 4 those leading to the cylinders Steam pipes and 5 the steam pipe leading from the dome 6 to the superheater. At the At the end of the steam pipe 5, the throttle valve 7 is arranged in the dome 6.

Der Kessel ist mit einer vorteilhaft zylindrischen Kammer 8 versehen, die nach der Rauchkammer 2 offen ist und rückwärts bis nahe an die Feuerbüchse 9 reicht. Der Mantel 10 und die Hinterwand 11 der Kammer 8 bilden also einen Teil der Wandung des Kessels. Kurze Feuerröhren 12 gehen von der Rohrwand 13 der Feuerbüchse zu der Hinterwand 11 der Kammer 8. und sind an beiden Stellen dampfdicht eingesetzt: Die Röhren 12 ragen ein kurzes Stück durch die Wand χ ι in die Kammer 8 hinein. Rings um diese sind die Röhren 3 angeordnet, die von der Feuerbüchse 9 bis zur vorderen Rohrwand 14 reichen. Diese Röhren führen die Feuergase unmittelbar von der Feuerbüchse zur Rauchkammer.The boiler is provided with an advantageous cylindrical chamber 8, which according to the Smoke chamber 2 is open and extends backwards to close to the fire box 9. The coat 10 and the rear wall 11 of the chamber 8 thus form part of the wall of the Boiler. Short fire tubes 12 go from the pipe wall 13 of the fire box to the Rear wall 11 of the chamber 8 and are on Both points used in a vapor-tight manner: the tubes 12 protrude a short distance through the Wall χ ι into the chamber 8. Around this the tubes 3 are arranged, which of the fire box 9 to reach the front pipe wall 14. These tubes carry the Fire gases directly from the fire box to the smoke chamber.

Eine zylindrische, dampf dichte Kammer 15 bildet den Überhitzer. Dieser hat flache Endwandungen 16 und 17 und ist mit einer Anzahl von Feuerröhren 18 versehen, welche durch die Endwandungen 16 und 17 hindurchgehen. Die Röhren reichen noch etwas über die Endwandungen 16 hinaus. Die Anzahl der Röhren 18 ist gleich der Anzahl der Röhren 12, sie sind auch in derselben Weise wie diese angeordnet, haben jedoch einen so großen Durch- ; > messer, daß sie, wenn der Überhitzer 15 in die Kammer 8 gebracht wird, über die Enden der Röhren 12 geschoben werden können und die Fortsetzung der letzteren bilden.A cylindrical, steam-tight chamber 15 forms the superheater. This has flat end walls 16 and 17 and is provided with a number of fire tubes 18 which through end walls 16 and 17 pass therethrough. The tubes still extend a little over the end walls 16 addition. The number of tubes 18 is equal to the number of tubes 12, them are also arranged in the same way as this, but have such a large diameter; > knife that, when the superheater 15 is brought into the chamber 8, over the ends of the Tubes 12 can be pushed and form the continuation of the latter.

Aus der Öffnung 19, an welche das Ende des Dampfrohres 5 angeschlossen ist, gelangt der *Dampf zunächst in eine Kammer 20 (Fig. 1). Diese wird durch eine Scheidewand 21 (Fig. 3) begrenzt, die sich quer durch das Vorderende des Überhitzers erstreckt. Eine senkrechte Scheidewand 22 reicht von der Oberwand des Überhitzers zu der Scheidewand 21. Diese senkrechte Wand hat Öffnungen, durch welche die Röhren 18 dampfdicht hindurchgehen. In der Scheidewand 22 befindet sich eine Öffnung 23, vonFrom the opening 19 to which the end of the steam pipe 5 is connected, the * steam first enters a chamber 20 (Fig. 1). This is limited by a partition wall 21 (Fig. 3), which extends transversely extends through the front end of the superheater. A vertical partition 22 extends from the top wall of the superheater the partition wall 21. This vertical wall has openings through which the tubes 18 pass through vapor-tight. In the partition 22 there is an opening 23 of

Claims

which a tube 24 extends rearward. This tube ends shortly before the rear wall 16 and serves to guide the steam passing from the boiler into the chamber 20 of the superheater to the rear of the superheater. The steam leaves the superheater through the openings 25 located on the side below the chamber 21. The steam entering the superheater must therefore flow from the opening 19 through the pipe 24. Here it is overheated by the fire tubes 18 arranged in the tube, then the steam flows outside the tube 24 back along between the fire tubes 18 and, when it reaches the openings 25 to which the tubes 4 leading to the cylinders are connected, is highly overheated. Although it is advantageous to force the steam to circulate by the means just described, it will be appreciated that these means are not absolutely necessary for superheating the steam and that they may be omitted. Deflection plates 26 can also be attached in a known manner, as shown in the modified embodiment according to FIG. From this figure it can be seen that the illustrated arrangement of the baffles forces the steam to make a tortuous path. The distance of the fire box 9 from the end wall 11 of the chamber 8 is sufficient to cause the hot gases flowing from the fire box through the tubes 12 to give off sufficient heat to the boiler water to lower the temperature of the gases so much that the Gases no longer damage the superheater. However, the gases still have enough heat to superheat the steam to the desired temperature. A damper 28 is advantageously arranged behind the smoke chamber partition 27 (FIG. 1). The same is rotatably mounted about the axis 29 and is adjusted by the operator or automatically closed when the throttle valve is closed and automatically opened when the throttle valve is opened. The damper has to partially or completely close the end of the superheater and thereby partially close the hot gas flow through the superheater tubes. or to turn it off completely. The front end of the superheater extends beyond the front pipe wall so that the attachment of the steam inlet and outlet pipes is facilitated. . The space between the wall of the superheater and the wall of the chamber 8 acts as a jacket in order to keep the temperature of the steam passing through the superheater as high as possible. The described design of the boiler and the superheater allows an advantageous storage of the latter in the boiler interior and easy removal of the superheater for repairs. It is sufficient to detach the flanges of the steam pipes 4 and 5 from the corresponding flanges of the superheater. The superheater, which is only supported at the rear by the ends of the tubes 12, can then be pulled out through the smoke chamber. Godfather nt-A ν Proverbs :.

1. Heating tube boiler with a built-in boiler after the smoke chamber open chamber to accommodate a superheater, characterized in that that the ends of the superheater tubes pushed over the ends of the boiler tubes and thereby the superheater in the chamber is fixed.

2. Embodiment of the boiler according to claim 1, characterized in that the steam withdrawn from the boiler is initially divided into one at the front end of the superheater by walls (21, 22) Chamber (20) flows, from there through a central longitudinal tube (23) to the rear is passed and then flushing around the heating pipes located outside the pipe (23) reaches the outlet openings (25).
