Description

Dampfkesselanlage mit Speisewasserspeicher zum Ausgleich von Belastungsschwankungen Da der -%,Virkungsgrad bei Dampfkesselanlagen bei unregelmäßiger Belastung erheblich sinkt, hat man vorgeschlagen, zur Zeit geringer Belastung heißes Wasser aufzuspeichern und mit diesem zur Zeit erhöhten Dampfbedarfs den Kessel zu speisen. Dieses Verfahren ist indessen in seiner Wirkung beschränkt und hat daher keine Bedeutung erlangen können.Steam boiler system with feed water storage tank to compensate for fluctuations in load Since the -%, degree of efficiency in steam boiler systems is considerable with irregular loads drops, it has been suggested to store hot water at times when the load is low and to feed the boiler with this currently increased steam requirement. This method however, it is limited in its effect and therefore has no significance can.

Nach der Erfindung wird ein sehr vollkommener Belastungsausgleich bei Dampfkessela.nlagen dadurch ermöglicht, daß die Aufspeicherung von heißem Wasser mit an sich ebenfalls bekannten Dampfaufspeicherungsverfahren derart vereinigt wird, daß der allgemeine Ausgleich mittels des Speisewasserspeichers und Ausgleich der Spitzen mittels des üblichen, bei Volldruck arbeitenden Speichers erfolgt. Man kann dabei die Anordnung so treffen, daß beisinkendemKes: seldruck, der ein Zeichen für verstärkten Dampfbedarf ist, zunächst der Speisewasserspeicher benutzt und bei sehr starker, stoßweiser Dampfentnahme auch der Hochdruckspeicher in Benutzung b °nommen wird. Das Verhältnis der Größe b,:ider Speicher richtet sich nach dem voraussichtlichen Lauf der Belastungskurve. Im allgemeinen wird man mit einem kleineren Hochdruckspeicher auskommen.According to the invention, there is a very perfect load balancing in Dampfkessela.nlagen this enables the storage of hot water is combined with steam accumulation processes, which are also known per se, in such a way that that the general compensation by means of the feed water storage and compensation of the Peak takes place by means of the usual, working at full pressure memory. One can Arrange the arrangement in such a way that when the If there is an increased demand for steam, the feed water storage tank is initially used and at a very high level strong, intermittent steam extraction, the high-pressure accumulator also came into use will. The ratio of the size b: id of the memory depends on the expected Course of the load curve. In general, you will use a smaller high pressure accumulator get along.

An die Stelle des Hochdruckspeichers können auch andere Sp:,-ichetrarten treten, beispielsweise solche, bei welchen zur Aufspeicherung Salzlösungen ver"vendet werden, die bei hoher Temperatur geringe Drucke zeigen und bei denen außerdem gegebenenfalls die Verdünnungswärme der Salzlösungen ausgenutzt wird.Instead of the high-pressure accumulator, other storage tanks can also be used occur, for example those in which saline solutions are used for storage which show low pressures at high temperature and at which also optionally the heat of dilution of the salt solutions is used.

In der Zeichnung ist eine Anlage zur Ausführung des Verfahrens dargestellt. Dem mit Vorwärmen a versehenen Dampfkessel b sind zwei Speicher, nämlich ein Speisewasserspeicher c und ein Dampfspeicherd, zugeordnet. Die Pumpte b,ef5rdert das Speisewasser durch den Vorwärmera in die zum Speicherkessel c führende Leitung/. Aus dem Speicher c kann das Wasser mittels der Pumpe g durch die Leitung h und i in den Dampfkessel übergeführt werden. Die Leitungen f und lt sind durch die mit Absperrvorrichtung h versehene Leitung m ver- bunden. Von der Dampfleitung n führen die Abzweigleitung o zum Speicher c und die Abzweigleitung p und r zum Speicher d. In die Leitung o ist eine Drosselvorrichtung s :eingeschaltet, die beispielsweise auch aus einer Gegendruckmaschine bestehen kann. Die Lei-;tt 4g en p und r enthalten in entgeg engesietz--ter Richtung wirkende Rücksichlagklappen t bzw. u.The drawing shows a system for carrying out the method. The steam boiler b, which is provided with preheating a, is assigned two storage tanks, namely a feed water storage tank c and a steam storage tank d. The pump b, conveys the feed water through the preheater into the pipe leading to the storage boiler c. From the memory c, the water can be transferred to the steam boiler by means of the pump g through the lines h and i. The lines f and h lt through the conduit provided with shut-off comparable m inhibited. The branch line o leads from the steam line n to the reservoir c and the branch lines p and r to the reservoir d. In line o, a throttle device s: is switched on, which can also consist of a counter-pressure machine, for example. The lines 4g en p and r contain rear view flaps t and u which act in the opposite direction.

Wenn der Kesseldruck zu niedrig ist, so wird zunächst durch die Leitung r aus dem Speicher d Dampf in die zur Verbrauchsstelle führende Leitung n eintreten. Der Hochdruckspeicher d wird somit entladen. Dann wird das Ventil k selbsttätig oder von Hand geschlossen und aus dem Speicher c heißes Wasser zur Speisung des Kessels entnommen, indem das Spelsewasser durch die Leitunglt und z in den Kessel c gedrückt wird.If the boiler pressure is too low, it is first through the line r enter from the memory d steam into the line n leading to the point of consumption. The high-pressure accumulator d is thus discharged. Then the valve k becomes automatic or closed by hand and hot water from the memory c to feed the Kettle removed by letting the flushing water through the line and z into the kettle c is pressed.

. Ist der Druck zu hoch, so wird der Kessel d durch die Leitung p und der Kessel c durch die Leitung o hindurch aufgeladen und durch öffnen des Ventils k bewirkt, daß der Speisewasserstrom vom Vorwärmen a durch die Leitungen f, m, lt, ä unmittelbar in den Kessel b gelangt.. If the pressure is too high, the boiler d is charged through the line p and the boiler c through the line o and by opening the valve k causes the feed water flow from the preheating a through the lines f, m, lt, ä directly enters boiler b.

Die Ventile t und u "werden so, eingestellt, daß sie bei kleinen Druckschlvankungen ansprechen, und der Speicher d wird so bemessen, daß er die betriebsmäßig auftretenden kurzen Dampfentnahmeschwan'kungen aufnehmen kann. Die großen, lang andauernden Schwankungen werden auf den Speicher c abgewälzt, der bei, seinem geringen Druck entsprechend aufnahmefähig gemacht wird.The valves t and u "are set in such a way that they respond to small pressure fluctuations, and the memory d is dimensioned so that it can accommodate the short steam extraction fluctuations that occur during operation. The large, long-lasting fluctuations are passed on to the memory c , which is made receptive to its low pressure accordingly.
