Description

Es ist bekannt, zur Ausnutzung der in den Abgasen von Lokomotivkesseln noch enthaltenen Wärme hinter :den normalen Lokomotivkessel einen mit Abgas beheizten Speisewasservorwärmer zu schalten. Da bei dem niedrigen nur, noch zur Verfügung stehenden Temperaturgefälle vom Gas an das Wasser eine verhältnismäßig großeVorwärmerheizfläche benötigt wird, bereitet die Anordnung der Vorwärmerheizfläche auf :der Lokomotive erhebliche Schwierigkeiten. So gibt es Ausführungen mit Wärme-austauschertrommeln beiderseits des Langkessels, durch :die die Rauchgase von vorn nach hinten durch Röhrenbündel geleitet werden, die vom Speisewasser umspült werden. Diese Trommeln sind vorn an die weit nach unten gezogene Rauchkammer angeschlossen. Die Rauchgase werden nach Durchströmen der Vorwärmer durch seitlich um den Langkessel nach oben geführte Schornsteine abgeführt. Diese Konstruktion führt zu einer sehr schweren Rauchkammerkonstruktion, zu einer unsymmetrischen, nach unten gezogenen Tür und zu einem unorganischen Aufbau, da die Vorwärmer vorn an der Rauchkammer hängen und hinten auf dem Rahmen ruhen. Die Ausnutzung der aufgewandten Baustoffe ist schlecht. Die Sicht vom Führerstand ist behindert.It is known to take advantage of the in the exhaust gases from locomotive boilers still contained heat behind: the normal locomotive boiler is heated with exhaust gas To switch the feed water preheater. Since at the low only, still available standing temperature gradient from the gas to the water a relatively large preheater heating surface is required, prepares the arrangement of the preheater heating surface: the locomotive considerable difficulties. There are versions with heat exchanger drums on both sides of the long boiler, through: which the flue gases through from the front to the back Tube bundles are passed, which are washed by the feed water. These drums are connected at the front to the smoke chamber, which is drawn far down. The smoke gases after flowing through the preheater through the side of the long boiler upwards guided chimneys removed. This construction leads to a very serious one Smoke chamber construction, to an asymmetrical, downwardly drawn door and to an inorganic structure, since the preheaters are attached to the front of the smoke chamber and rest on the frame at the back. The utilization of the building materials used is poor. The view from the driver's cab is obstructed.

Diese Nachteile werden .durch die Erfindung vermieden. Sie ist .dadurch gekennzeichnet, daß die Rauchgase aus dem Kessel am Boden der Rauchkammer,durch einen Ausschnitt in den allseitig geschlossenen Rauchkammerträger und von dort in den an den Träger angeschlossenen Vorwärmer übertreten.These disadvantages are avoided by the invention. It is .through it characterized in that the smoke gases from the boiler at the bottom of the smoke chamber, through a cutout in the smoke chamber support, which is closed on all sides, and from there in pass over the preheater connected to the carrier.

Der normale Lokomotivkessel i bleibt in seiner Grundform vollständig erhalten. Er wird auch in bekannter Weise- auf dem einen Teil des Rahmens bildenden Rauchkammerträger 2 aufgelagert. Der Träger 2 wird nunmehr in seinem unterhalb der Rauchkammer des eigentlichen Kessels liegenden Teil als geschlossener Raum ausgebildet, vorn durch eine Tür 3 zugänglich. Nach hinten schließt sich die Rauchgasvorwärmertrommel q. an, die durch den Ausschnitt 5 im Träger - von hinten eingeschoben und mit ihm verbunden ist. Durch einen Ausschnitt 6 im Boden der Rauchkammer des Kessels i treten die Rauchgase in .den Rauchkammerträger 2, und von dort in den Rauchgasvorwärmer :4. Um !das Mitreißen von Flugasche in den Vorwärmer zu vermindern und um die Blasrohrauswirkung möglichst gleichmäßig auf .die Rohrwand des Kessels i zu verteilen, ist in Ausschnitt 6 ein Einsatz 7, schräg nach vorn gerichtet, mit seiner oberen . Eintrittsöffnung zur Umlenkung der Rauchgase eingesetzt. Der Einsatz kann leicht herausgenommen werden, um an, die Kesselrohre des Kessels ii zu gelangen. Der vorn am Rauchkammerträger 2 festsitzende Vorwärmer q. ist hinten am Kessel :i mit Blechen 8, g pendelnd aufgehängt, so daß er sich frei ausdehnen kann.The normal locomotive boiler i remains complete in its basic form obtain. He is also in a known manner - on the one part of the frame forming Smoke chamber support 2 supported. The carrier 2 is now in its below the The smoke chamber of the actual boiler is designed as a closed space, Accessible through a door 3 at the front. The flue gas preheater drum closes at the rear q. to that through the cutout 5 in the carrier - inserted from behind and with him connected is. Step through a cutout 6 in the bottom of the smoke chamber of the boiler i the flue gases in .the smoke chamber support 2, and from there into the flue gas preheater : 4. To reduce fly ash entrainment into the preheater and to reduce the blowpipe effect to distribute as evenly as possible on the pipe wall of the boiler i is in the cutout 6 an insert 7, directed obliquely forward, with its upper one. Inlet opening used to redirect the smoke gases. The insert can be easily removed to get to the boiler tubes of boiler ii. The one at the front of the smoke box support 2 fixed preheaters q. is at the back of the boiler: i is suspended from metal sheets 8, g pendulum, so that it can expand freely.

Die Rauchgase werden durch Blasrohre ro und Seitenschornstein in aus dem Abgasvorwärmer nach außen gefördert. Um die Sicht vom Führerstand nach vorn durch den Seitenschornstein nicht zu behindern, ist dieser einmal auf der Heizerseite angeordnet, außerdem oval ausgebildet und in einer Einpolterung i:2 des Langkessels nach oben geführt.The flue gases are in out through blowpipes ro and side chimney conveyed to the outside of the exhaust gas preheater. To the view from the driver's cab to the front not to be obstructed by the side chimney, this is once on the heater side arranged, also oval and in a polishing i: 2 of the long boiler led up.
