Description

Dampfkraftanlage mit durch .Entnahmedampf gespeisten Verbrauchern Wird, wie es bisher bei der Speisung von Verbrauchern durch Entnahm-adampf, d. h. Dampf, der einer Zwischenstufe der Kraftmaschine entnommen wird, üblich war, die Entnahmemenge durch einen Druckimpuls überwacht, so kann es bei stark gesteigertem Bedarf der Verbraucher vorkommen, .daß die Entnahmemenge einen Wert erreicht, der die maximale Entnahmemenge, bei der die Maschine noch ihre volle Leistung hergibt, übersteigt. Die Maschinenleistung m.uß also absinken, da die Entnahmemenge durch -den Druckimpuls nach .dem Bedarf der Verbraucher .geregelt wird. Eine Verringerung der Maschinenleistung zu Gunsten der Dampfverbraucher ist unerwünscht. Um diese Möglichkeit auszuschließen, wird gemäß der Erfindung die Entnahmemenge durch einen Mengenmesser überwacht, der inAen zu den Verbrauchern führenden Leitungen liegt. Soll außerdem der Dampf bei den Verbrauchern auch in jedem Falle einen bestimmten Druck haben, so werden die Verbraucher noch in bekannter Weise an eine weitere Speiseleitung gelegt, die das Gegendrucknetz unmittelbar m.it dem Frisch:dampfnetz über ein Druckmi.nderventil verbindet. Gegebenenfalls kann in diese Verbindungsleitung noch vor das Druckminderventil ein Überströmventil mit parallel zur Leitung angeordnetem Wärmespeicher gelegt werden.Steam power plant with consumers fed by extraction steam As has been the case until now with the supply of consumers by extraction steam, i. H. Steam taken from an intermediate stage of the engine was common Withdrawal quantity monitored by a pressure pulse, so it can be with greatly increased Needs of the consumer, .that the withdrawal amount reaches a value that the maximum withdrawal quantity at which the machine can still produce its full capacity, exceeds. The machine output must therefore decrease, as the withdrawal quantity decreases -the pressure pulse is .regulated according to .the needs of the consumer. A decrease the machine performance in favor of the steam consumer is undesirable. Around Rule out the possibility, according to the invention, the withdrawal amount by a Monitored the flow meter, which is located in the lines leading to the consumers. In addition, should the steam at the consumers be a certain one in each case If there is pressure, the consumers are still connected to another feed line in a known manner which the counter pressure network directly with the fresh steam network via a pressure medium valve connects. If necessary, this connecting line can be placed upstream of the pressure reducing valve an overflow valve with a heat accumulator arranged parallel to the pipe.

In-den Abb. i und 2 sind zwei Schaltbilder dargestellt, die die neue Anordnung enthalten. In der Abbildung i sollen die Verbraucher i aus der Entnahmeleitung 2 gespeist werden. Die Entnahmeleitung 2 kommt von einer Maschine 3 mit dem Hochdruckteil q. und dem Niederdruckteil 5. Diese Maschine 3 ist an eine Leitung 6 angeschlossen, die aus dem Kessel 7 gespeist wird. Die Menge des aus der Maschine in der Leitung 2 ;gelangenden Dampfes wird durch einen Mengenmesser 8 überwacht, der .das Entnahmeventil 9 steuert, wie es die Linie io andeutet. Die Leitung 2 steht durch eine Leitung z i mit der Leitung 6 in Verbindung. Durch diese Leitung i i wird der Druck :des an -die Verbraucher i abgegebenen Dampfes konstant gehalten, und zwar durch das Druckminderventil 13 in ,der Leitung i i. Die Dampfzufuhr .aus der Leitung 6 in die Leitung ii, an die ein Speicher 15 angeschlossen ist, wird in bekannter Weise durch ein Überströmventi.l 1q. gesteuert.In-Figs. I and 2 two circuit diagrams are shown which contain the new arrangement. In the illustration i, the consumers i are to be fed from the extraction line 2. The extraction line 2 comes from a machine 3 with the high pressure part q. and the low-pressure part 5. This machine 3 is connected to a line 6 which is fed from the boiler 7. The amount of steam coming out of the machine in line 2; is monitored by a flow meter 8 which controls the extraction valve 9, as indicated by the line io. The line 2 is connected to the line 6 by a line zi. Through this line ii the pressure: of the steam delivered to the consumer i is kept constant, namely through the pressure reducing valve 13 in line i i. The steam supply .from line 6 into line ii, to which a memory 15 is connected, is controlled in a known manner by an overflow valve 1q. controlled.

In Abbildung 2, bei der die gleichen Bezugszeichen gewählt sind, ist als Verbraucher ein Verdampfer i dargestellt, dem der Heizdampf wieder durch die zwei getrennten Leitungen 2 und ii zugeführt wird. Der zusätzliche Dampf -aus der Leitung i i wird bei dieser Anordnung durch einen Impuls 12 gesteuert, der den Druck auf der Verdampferseite überwacht.In Figure 2, where the same reference numerals have been chosen, is shown as a consumer an evaporator i, to which the heating steam again through the two separate lines 2 and ii is fed. The extra steam -from the Line i i is controlled in this arrangement by a pulse 12, the pressure monitored on the evaporator side.
