Description

Dampfkesselanlage mit Speisewasserspeicher und zwischen Rauchgasvorwärmer und Kessel angeordnetem Behälter. Es ist bekannt, bei Dampfkesselanlagen za,ischen Rauchgasvorwärmer und Dampfkessel einen Behälter einzuschalten, der bei abgestellter Speisewasserzufuhr zur Kesselanlage das durch den Rauchgasvorw ärmer strömende vorgewärmte Speisewasser aufnimmt. Hierdurch werden die unerwünschte Dampfbildung und Wasserschläge im Rauchgasvorwärmer vermieden, die sonst bei abgestelltem Durchfluß infolge zu hoher Erwärmung auftreten könnten.Steam boiler system with feed water storage tank and between flue gas preheater and boiler arranged container. It is known to be used in steam boiler systems Flue gas preheater and steam boiler to switch on a container that is switched off Feed water supply to the boiler system that is preheated flowing through the flue gas preheater Absorbs feed water. This prevents the undesirable formation of steam and water hammer avoided in the flue gas preheater, which would otherwise be due to the flow being turned off high temperatures could occur.

Die vorliegende Erfindung bezieht sich auf Dampfkesselanlagen mit schwankender Belastung, bei denen ein derartiger Behälter zwischen Rauchgasvorwärmer und Kesselanlage vorgesehen ist. Das Wesen der Erfindung besteht darin, daß zwischen Behälter und Kesselanlage eine Pumpe angeordnet ist, die so bemessen ist und so geregelt wird, daß die aus dem Sammelbehälter in Zeiten geringen Dampfverbrauchs in den Kessel geförderten Wassermengen die überschreitung des Drucks im Kessel verhindern, wobei die überschüssige Wärme als Heißwasser von hoher Temperatur gespeichert werden kann. Auf diese Weise ist es möglich, die Kesselanlage in Zeiten geringer Belastung mit großen Mengen Wasser von niedriger Temperatur, entsprechend der durchschnittlichen Austrittstemperatur aus dem Rauchgasvorwärmer, zu speisen und hierdurch ein Abblasen der Sicherheitsventile und Dampfverlust in der Kesselanlage zu vermeiden.The present invention relates to steam boiler systems with fluctuating load, in which such a container between the flue gas preheater and boiler system is provided. The essence of the invention is that between Container and boiler system a pump is arranged, which so sized is and is regulated so that the steam from the collecting tank in times of low steam consumption prevent the amount of water pumped into the boiler from exceeding the pressure in the boiler, the excess heat being stored as hot water of high temperature can. In this way it is possible to shut down the boiler system during times of low load with large amounts of water of low temperature, corresponding to the average Outlet temperature from the flue gas preheater, to be fed and thereby a blow-off safety valves and steam loss in the boiler system.

In der Zeichnung ist eine Anlage gemäß der Erfindung beispielsweise dargestellt.In the drawing, a system according to the invention is for example shown.

Der Dampfkessel a ist in an sich bekannter Weise mit dem Speicher b verbunden; durch die Pumpe c wird erhitztes Wasser in den Speicher übergeleitet, während die Pumpe d zum Speisen des Kessels mit Speicherwasser dient, wenn der erhöhte Dampfbedarf dieses nötig macht. Die Speisepumpe e saugt aus dem Behälter f frisches Speisewasser und drückt dieses durch den Rauchgasvorwärmer g in den geschlossenen Sammelbehälter h. Je nach Bedarf wird das vorgewärmte Wasser durch die Pumpe i dann in den Kessel a weitergeleitet. Wesentlich ist, daß der Behälter h als Druckbehälter ausgeführt ist, so daß das aus dem Rauchgasvorwärmer g kommende Wasser keine Druckentlastung und keinen Wärmeverlust erfährt, sondern mit demselben Druck und derselben Temperatur in den Kessel a weitergespeist- werden kann. Naturgemäß ist es auch möglich, für gewisse Zwecke aus dem Speisewasserbehälter lt Dampf von geringer Spannung zu entnehmen. Gleichzeitig können aber auch im Fabrikbetrieb anfallende Kondenswasser von der hier herrschenden Spannung eingeleitet werden, so daß auch hierbei die sonst meist unvermeidlichen Wärmeverluste beseitigt werden können.The steam boiler a is connected to the memory b in a manner known per se; Heated water is transferred to the storage tank by pump c, while pump d is used to feed the boiler with storage tank water if the increased demand for steam makes this necessary. The feed pump e sucks fresh feed water from the container f and presses it through the flue gas preheater g into the closed collecting container h. Depending on requirements, the preheated water is then passed on to the boiler a by the pump i. It is essential that the container h is designed as a pressure vessel so that the water coming from the flue gas preheater g experiences no pressure relief and no heat loss, but can instead be fed into the boiler a at the same pressure and temperature. Of course, it is also possible for certain purposes to take low-voltage steam from the feed water tank. At the same time, however, condensation water occurring in the factory can also be introduced by the voltage prevailing here, so that the otherwise usually unavoidable heat losses can also be eliminated here.

In dem Behälter kann unter Umständen der Druck infolge der Schwankungen des Wasserspiegels oder infolge von Abkühlung schwanken, und es ist daher, um Dampfbildung im Vorwärmer zu verhindern, angebracht, den Druck im Vorwärmer so zu regeln, daß er nicht unter den der Temperatur des vorgewärmten Wassers entsprechenden Druch sinken kann.In the container, the pressure can under certain circumstances as a result of the fluctuations the water level or as a result of cooling fluctuate, and it is therefore due to steam formation to prevent in the preheater, appropriate to regulate the pressure in the preheater so that it does not fall below the pressure corresponding to the temperature of the preheated water can sink.
