Description
Dampfkraftanlage mit einem Hochdruckdampferzeuger und einem von der Feuerung desselben beheizten Niederdkdampferzeuger Die Erfindung betrifft eine Dampfkraftanlage mit einem Hochdruckdampferzeuger und einem von der Feuerung desselben beheizten Niederdruckdampferzeuger, welcher den Betriebsdampf für eine Hilfskraftmaschine liefert.Steam power plant with a high pressure steam generator and one of the Firing the same heated low-steam generator. The invention relates to a steam power plant with a high pressure steam generator and one heated by the furnace of the same Low-pressure steam generator, which supplies the operating steam for an auxiliary engine supplies.
Sie besteht in dem Vorschlag, die Hilfskraftmaschine zum Betrieb der Arbeitsmittelfördereinrichtungen für die beiden Dampferzeuger zu benutzen, deren Feuerung in Abhängigkeit vom Hochdruckdampfbedarf geregelt ist.It consists in the proposal that the auxiliary engine to operate the To use work equipment conveying devices for the two steam generators, their Firing is regulated depending on the high pressure steam requirement.
Eine so betriebene Dampfkraftanlage hat' die vorteilhafte Eigenschaft, daß sich bei einer Änderung der Beheizung der Kessel die Arbeitsmittelzufuhr, wenigstens angenähert, selbsttätig der veränderten Behexzung anpaßt. Wird nämlich die Beheizung verstärkt, so erhält-die Hilfskraftmaschine unter erhöhtem Drück mehr Betriebsdampf, und die Arbeitsmittelzufuhr zu den beiden Kesseln steigert sich; vermindert sich die Wärmezufuhr, so tritt das Umgekehrte ein.A steam power plant operated in this way has the advantageous property that when there is a change in the heating of the boiler, the working medium supply, at least approximates, automatically adapts to the changed excitation. Namely, the heating reinforced, the auxiliary engine receives more operating steam under increased pressure, and the supply of work equipment to the two boilers increases; Decreases the supply of heat, the reverse occurs.
Soweit diese Selbstregelung in dem einen oder anderen Falle dhn. Anforderungen nicht voll genügt, hat man nur nötig, dafür zu sorgen, daß gegebenenfalls eine Feinregelung in geeigneter Weise zur Einwirkung gebracht werden kann.So much for this self-regulation in one case or another. requirements not fully sufficient, one only has to ensure that fine adjustments are made if necessary can be brought into action in a suitable manner.
Ein Ausführungsbeispiel der Erfindung ist in der Abbildung dargestellt.An embodiment of the invention is shown in the figure.
In der Abbildung ist i die Hauptkraftmaschine, 2 der Dampferzeuger mit einer Hauptheizfläche 3 und einer Zusatzheizfläche 4. Die Heizfläche 3 dient zur Erzeugung des Betriebsdampfes für die Hauptkraftmaschine i, während die Zusatzheizfläche 4 den niedriger gespannten Dampf für den Betrieb der Hilfskraftmaschine 5 liefert. Die beiden Heizflächenteile 3 und 4 werden von ein Emd derselben nicht dargestellten Feuerung beheizt. Der Abdampf der Hauptmaschine i wird in dem Kondensator 6 niedergeschlagen. Das in dem Kondensator 6 anfallende Kondensat wird mit Hilfe der Pumpen 7 und 8 durch die Vorwärmer 9 und io hindurchgedrückt und zur Speisung der Heizfläche 3 benutzt. Die Hilfskraftma-schine 5 treibt außer der Speisepumpe 8 noch eine Speisepumpe i i an, die zur Speisung der Zusatzheizfläche 4 dient. Falls es erforderlich ist, kann mit der Hilfskraftmaschine 5 noch .eine elektrische LeistungsausgIeichsmaschine 12 gekuppelt sein. Die Vorwärmer 9 und i o werden bei dem Ausführungsbeispiel mit dem Abdampf der Hilfskraftmaschine 5 oder mit Frischdampf aus dem Niederdrucknetz 13 beheizt. Falls keine Veräampferanlage zur Aufbereitung des Zusatzspeisewassers aufgestellt werden soll, wird das beispielsweise in dem chemischen Aufbereiter 14 aufbereitete Zusatzwasser zur Speisung der Zusatzheizfläche 4 verwandt. Für diesen Fall ist in die Dampfzuleitung zur Hilfskraftmaschin.e 5 ,ein Dampfwäscher 15 pinzuschalten. Durch den überhitzer 17 kann der erzeugte Hilfsdampf auf jede gewünschte Temperatur gebracht werden.In the figure i is the main engine, 2 the steam generator with a main heating surface 3 and an additional heating surface 4. The heating surface 3 is used to generate the operating steam for the main engine i, while the additional heating surface 4 supplies the lower-pressure steam for operating the auxiliary engine 5. The two heating surface parts 3 and 4 are not shown by an Emd of the same Firing heated. The exhaust steam from the main engine i is deposited in the condenser 6. The condensate accumulating in the condenser 6 is pumped out with the aid of the pumps 7 and 8 pushed through the preheaters 9 and io and to feed the heating surface 3 used. In addition to the feed pump 8, the auxiliary power machine 5 also drives a feed pump i i, which is used to feed the additional heating surface 4. If necessary, can with the auxiliary engine 5 still .an electrical power equalization machine 12 must be coupled. The preheaters 9 and i o are in the embodiment with the exhaust steam of the auxiliary engine 5 or with live steam from the low-pressure network 13 heated. If there is no vaporizer system for the treatment of the additional feed water is to be set up, this is done, for example, in the chemical processor 14 treated additional water used to feed the additional heating surface 4. For this The case is to switch a steam washer 15 into the steam supply line to the auxiliary power machine 5. By means of the superheater 17, the auxiliary steam generated can be heated to any desired temperature to be brought.
Es sei noch darauf hingewiesen, daß die Anwendung der Erfindung unabhängig davon ist, mit welchem Druck die Anlage betrieben wird. Die Erfindung kann auch dann zur Anwendung kommen, wenn die Anlage mit einem lastabhängig veränderlichen Eintrittsdruck vor der Kraftmaschine betrieben wird.It should be noted that the application of the invention is independent of which is the pressure at which the system is operated. The invention can also then come into use when the system with a load-dependent variable Inlet pressure is operated in front of the engine.
