Description
Aus Haupt- und Vorschaltmaschine bestehende Dampfkraftmaschinenanlage In neuerer Zeit hat man vielfach die Leistung bestehender Dampfkraftmaschinenanlagen dadurch erhöht, daß man einer von einer Kesselbatterie üblicher Dampfspannung gespeisten Hauptmaschine eine mit Dampf sehr hoher Spannung betriebene Hochdruckmaschine vorschaltete. Die das Treibmittel für die Vorschaltmaschine liefernden Hochdruckdampferzeuger «-aren hierbei so bemessen, daß sie dein Bedarf der lfaschinenanlage bei Grundbelastung genügten, während der darüber hinausgehende Bedarf bei Spitzenbelastungen von Dampferzeugern üblicher Spannung aufgebracht wurde.Steam power plant consisting of a main and upstream machine In recent times one has in many cases the performance of existing steam engine systems increased by the fact that one fed a normal steam voltage from a boiler battery The main engine was connected upstream with a high-pressure machine operated with very high voltage steam. The high-pressure steam generator that supplies the propellant for the upstream machine «-Are measured in such a way that they meet your needs for the engine system at the base load were sufficient, while the additional demand at peak loads of steam generators usual tension was applied.
Um die Belastungsschwankungen von den Hochdruckdampferzeugern und von den Hochdruckdampfmaschinen fernzuhalten, wird gemäß der Erfindung vorgeschlagen, die Füllung der Hochdruckmaschine in Abhängigkeit von dem Druck vor der Hauptkraftmaschine zu regeln und in der Dampfzuführungsleitung vom 1Tiederdruckdampferzeuger zur Hauptkraftmaschine ein Regelorgan anzuordnen, welches bei Unterschreitung eines bestimmten Druckes vor dem Eintritt in die Hauptkraftmaschine mehr Dampf aus dem Dampferzeuger zur Maschine strömen läßt.To deal with the load fluctuations from the high pressure steam generators and to keep away from the high pressure steam engines is proposed according to the invention, the filling of the high-pressure machine as a function of the pressure in front of the main engine and in the steam supply line from the low-pressure steam generator to the main engine to arrange a regulating body which, if the pressure falls below a certain value more steam from the steam generator before entering the main engine Lets machine flow.
In weiterer Ausgestaltung der Erfindung ist ferner die Einrichtung getroffen, daß beim Sinken des Hochdruckkesseldruckes unter ein bestimmtes Maß das Dampfeinlaßorgan der Vorschaltmaschine durch einen Kesseldruckregler geschlossen wird. Ferner wird beim Sinken des sich vor der Eintrittsseite der Hauptdampfmaschine einstellenden Gegendruckes unter ein gewisses Maß deren Einlaßorgan für niedergespannten Frischdampf selbsttätig entsprechend geöffnet.The device is also in a further embodiment of the invention made that when the high pressure boiler pressure falls below a certain level the Steam inlet element of the upstream machine closed by a boiler pressure regulator will. Furthermore, when the sink is in front of the inlet side of the main steam engine adjusting back pressure below a certain level their inlet organ for low tension Live steam automatically opened accordingly.
Der Erfindungsgegenstand ist in der Zeichnung in einem Ausführungsbeispiel veranschaulicht. Hierin bedeutet a eine Hauptdampfkraftmaschine, welche einerseits durch niedergespannten, in dem Kessel b erzeugten Frischdampf, andererseits durch Abdampf der V orschaltmaschine c oder auch von beiden Dampfarten gleichzeitig betrieben wird. Der zum Betrieb der V orschaltmaschine c benötigte hochgespannte Dampf wird in den Hochdruckdampfkesseln d erzeugt. e bezeichnet eine weitere an die Kesselbatterie b angeschlossene, gegebenenfalls noch vorhandene Dampfkraftmaschine, deren Generator mit demjenigen der Hauptmaschine a und der Vorschaltmaschine c auf ein gemeinsames .Netz arbeitet.The subject of the invention is shown in the drawing in one embodiment illustrated. Here, a means a main steam engine, which on the one hand by low-pressure live steam generated in boiler b, on the other hand by Exhaust steam from the upstream machine c or operated by both types of steam at the same time will. The high-pressure steam required to operate the upstream machine c is generated in the high pressure steam boiler d. e denotes another to the boiler battery b connected, possibly still existing steam engine, its generator with that of the main machine a and the upstream machine c on a common .Net works.
Bei gewöhnlichem Betrieb innerhalb der Grundbelastung empfängt die Hauptmaschine a ihren Arbeitsdampf von der Vorschahmaschine c. Der Gegendruckregler f hält den Druck vor dem Einlaßorgan g der Hauptmaschine a gleichbleibend, indem er die Füllung Gier Vorschaltmaschine entsprechend der Leistung der Hauptmaschine a regelt. L m zu vermeiden, daß bei großer Dampfentnahme aus der Hochdruckkess-elanlage d, deren Druck zu stark absinkt, ist ein Kesseldruckregler h. vorgesehen, welcher bei sinkendem Druck in der Hochdruckkesselanlage d das Einlaßorgan i der Vorschaltinasehine c allmählich entgegen der Wirkung des Gegendruckreglers f abschließt. Zwischen der \ iederdruckkesselanlage b und der Hauptniaschine a ist ferner ein Durchgangsventil k vorgesehen, welches durch einen besonderen Druckregler l gesteuert wird und niedergespannten Frischdampf zur Hauptmaschine a einläßt, wenn infolge hoher Leistungsaufnahme der Hauptmaschine a der Dampfdruck vor ihrem Einlaßorgan g unter ein bestimm-,es Maß sinkt.During normal operation within the base load, the main engine a receives its working steam from the fore engine c. The back pressure regulator f keeps the pressure in front of the inlet member g of the main engine a constant by regulating the filling yaw upstream machine according to the power of the main engine a. A boiler pressure regulator h is to be used to prevent large amounts of steam being drawn from the high-pressure boiler system d, the pressure of which drops too sharply. provided which, when the pressure in the high-pressure boiler system d drops, gradually closes off the inlet element i of the upstream kinase c against the action of the back pressure regulator f. A through valve k is also provided between the low-pressure boiler system b and the main machine a, which is controlled by a special pressure regulator l and lets in low-pressure live steam to the main machine a, if, due to the high power consumption of the main machine a, the steam pressure in front of its inlet element g falls below a certain, it decreases in degree.
Die Einrichtung kann auch so getroffen sein, daß das Durchgangsventil k unter Wegfall des besonderen Druckreglers L von dem gleichen Druckregler f wie das Dampfeinlaßorgan i der Vorschaltmaschine c gesteuert wird. In diesem Falle verstellt der'Druckregler f beide Ventile i, k nacheinander im gleichen Sinne.The device can also be designed in such a way that the through valve k is controlled by the same pressure regulator f as the steam inlet element i of the upstream machine c, eliminating the special pressure regulator L. In this case, the pressure regulator f adjusts both valves i, k one after the other in the same sense.
Es ist ferner auch angängig, das Durchgangsventil k durch den Kessel.druckregler lt beeinflussen zu lassen, wobei in diesem Falle die Ventile i und k im entgegengesetzten Sinne zueinander, gegebenenfalls gleichzeitig, verstellt werden.It is also possible to let the two-way valve k be influenced by the boiler pressure regulator lt, in which case the valves i and k are adjusted in opposite directions to one another, possibly simultaneously.
Die Beeinflussung des Durchgangsventils k durch einen der beiden Druckregler f oder lt empfiehlt sich insbesondere dann, wenn die Verstellung des Ventils h unter Zwischenwirkung einer Ölfernsteuerung erfolgt.The influence of the two-way valve k by one of the two pressure regulators f or lt is particularly recommended when the adjustment of the valve h is below Intermediate effect of a remote oil control takes place.
Da der Fliehkraftregler na der Hauptmaschine a innerhalb der Grundbelastung über den Gegendruckregler f die Füllung der Vorschaltmaschine c regelt, so wirkt der Fliehkraftregler iz der Vorschaltmaschine e lediglich als Sicherheitsregler,' der nur bei Überschreitung der zulässigen Drehzahl in Tätigkeit tritt.Because the centrifugal governor na the main engine a within the base load regulates the filling of the ballast machine c via the back pressure regulator f, so acts the centrifugal governor iz the upstream machine e only as a safety controller, ' which only comes into operation when the permissible speed is exceeded.
