Description
Dampfkesselanlage mit mehreren Kesseln, deren Dampfräume mit dem Dampfraume eines unter gleicher Spannung stehenden Speisewasserspeichers verbunden sind. Die Erfindung bezieht sich auf Dampfkesselanlagen mit Speisewasserspqichern,- denen das Speisewasser vor seinem Eintritt in die Kessel zugeführt wird und wo es sich auf Verdampfungstemperatur d'arch Kesseldampf erwärmt. Es sind solche Dampfkesselanlagen bekannt, bei denen jeder Dampfkessel mit einem Speisewasserspeicher versehen ist. Diese Anlagen haben den Nachteil, daß der Dampf für die Erwärmung des Speisewassers nur von :dem Kessel geliefert *i-rd, in dessen Speicher gerade Speisewasser eintritt. Die Kessel, deren Speicher während derselben Zeit nicht gespeist werden, müssen dann die ganze Betrliebsdämpfmenge liefern, werden dadurch leicht überlastet und liefern nassen Dampf.Steam boiler system with several boilers, their steam rooms with the steam room of a feed water storage tank under the same voltage. the Invention relates to steam boiler systems with Speisewasserspqichern, - those the feed water is supplied before it enters the boiler and where it is heated to evaporation temperature d'arch boiler steam. There are such steam boiler systems known, in which each steam boiler is provided with a feed water storage tank. These systems have the disadvantage that the steam for heating the feed water only supplied by: the boiler * i-rd in whose storage tank feed water is currently entering. The boilers whose tanks are not fed during the same time must then deliver the entire amount of operational damping, are thereby easily overloaded and deliver wet steam.
In dieser Beziehung liegen die Verhältnisse ebenso Wie beim üblichen Speisen -der Kessel einer Kesselbattcrie, denn auch dabei wird die Dampferzeugung in den Kesseln, die gerade gespeist werden, beeinträchtigt. Dies .hat nicht zur Folge, daß die Spannung in solchem Maße fällt wie bei einem Einzelkessel, weil die anderen Kessel der Batterie, die zufällig während dieser Zeit nicht gespeist werden, in erhöhtem Maße Dampf abgeben, während sich d!ie Dampfentwickelung in .den Kesseln, die gerade gespeist werden, vermindert oder ganz aufhört. Die Folge ist eine Überlastung der Kessel, die gerade nicht gespeist werden, so daß diese nassen Dampf liefern.In this respect the conditions are just as in the usual Food - the kettle of a kettle battery, because steam is also generated here in the boilers that are currently being fed. This. Has not to The result is that the voltage drops to the same extent as with a single boiler, because the other boilers of the battery that happen to be not powered during this time, give off steam to a greater extent, while the steam is generated in the boilers, that are currently being fed, reduced or completely stopped. The result is an overload the boilers, which are currently not being fed, so that these supply wet steam.
Das Problem, diesen Übelstand zu verhindern, löst die Erfindung dadurch, d'aß ein für die ganze Kesselbatterie gemeinsamer Speisewasserspeicher vorgesehen ist, dessen oberer Teil mit den Dampfräumen der Kessel in Verbindung steht und lin den das Speisewasser fein verteilt eingeführt wird, so daß es sich bereits im 'Dampfraume des Speichers bis .auf Verdampfungstemperatur erwärmt. Dadurch Wird erreicht, daß sämtliche Kessel der Batterien gemeinsam die Wärme für die Temperatursteigerung des Speisewassers bis auf Verdampfungstemperatur liefern, denn der Dampf, .der beim Eintritt des Speisewassers in den Dampfraum des gemeinschaftlichen Speisewasserspeichers kondensiert' wird, Wird sämtlichen Kesseln [in gleichem Maße entnommen, da .er Speicher an die gemeinschaftliche Dampfleitung der Kessel angeschlossen - ist wie irgendein anderer Dampfverbraucher, z. B. eine Dampfmaschine oder ein Kocher, der auch aus allen Kesseln gemeinsam den -Dampf empfängt.The invention solves the problem of preventing this drawback by d'ass a common feed water storage for the entire boiler battery is provided is, the upper part of which is in connection with the steam chambers of the boiler and lin the feed water is finely distributed so that it is already in the 'steam room of the storage tank heated up to the evaporation temperature. This achieves that all boilers of the batteries share the heat for the temperature increase of the feed water up to evaporation temperature, because the steam Entry of the feed water into the steam room of the communal feed water storage tank is condensed 'is taken from all boilers [to the same extent as the storage tank connected to the common steam pipe of the boiler - is like any other steam consumer, e.g. B. a steam engine or a cooker, which is also made receives the steam together with all boilers.
In dieser Beziehung unterscheidet sich auch das Einführen des Speisewassers in fein verteiltem Zustand in den gemeinschaftlichen Speisewasserspeicher grundsätzlich vom fein verteilten Einführen dies Speisewassers in die einzelnen Kessel einer Batterie, da, wie oben dargelegt wurde, dadurch eine Überlastung der gerade nicht gespeisten Kessel hervorgerufen wird, und zwar in noch stärkerem Maße, als wenn das Speiisewasser, welches sich noch nicht auf Verdampfungstemperatur befindet, in dem Wasserraum des Kessels Oingeführt wird. Wird das Speisewasser in den Wasserraum eingeführt, so bedarf es noch ainer gewissen Zeit, bis es sich mit dem Wasser gemischt hat. Wird es dagegen fein verteilt in den Dampfraum der einzelnen Kessel dingeführt, so wird die Dampfabgabe augenblicklich um so viel vermindert, wie sich Dampf an dem kälteren Wasser rniederschlägt.The introduction of the feed water also differs in this respect in a finely divided state in the common feed water storage tank from the finely divided introduction of this feed water into the individual boilers of a battery, because, as explained above, this causes an overload of the currently unpowered Boiler is generated, and to a greater extent than when the feed water, which is not yet at evaporation temperature, in the water space of the Boiler Ointroduced. If the feed water is in the Water space introduced, it takes a certain time before it mixes with the water Has. If, on the other hand, it is finely distributed into the steam space of the individual boilers, so the steam output is instantly reduced by as much as there is steam the colder water.
Der gemeinsame Speisewasserspeicher, der für die ganze Kesselbatterie der Erfindung entsprechend vorgesehen wird, wird an die Hauptdampflentung vor oder besser noch hinter dem Überhitzer angeschlossen. Wird in einen solchen Speisewasserspeicher zum Zwecke des Leistungsausgleiches bei kleinem Nutzdampfbedarf stark und bei großem Nutzdampfbedarf wenig eingespeist, so beteiligen sich doch stets alle Kessel der Batterie in gleichem Maße an der Lieferung des Dampfes für die Erwärmung des Speisewassers.The common feed water storage tank for the entire boiler battery the invention is provided according to the main steam vent or before better still connected behind the superheater. Used in such a feed water storage tank for the purpose of power equalization with small useful steam demand strong and with large If the demand for useful steam is little fed in, all the boilers always contribute Battery equally involved in the supply of steam for heating the feed water.
Mit den bekannten Wärmespeichern, bei denen ein Leistungsausgleich dadurch erzielt wird, daß der Wasserinhalt dieser Speicher unter Spannungs- und Temperatursteigerung Dampf aufnimmt und unter Spannungs- und Temperaturabnahme Dampf abgibt, hatdc@r Erfindungsgegenstand nichts zu tun.With the well-known heat accumulators, in which a power equalization is achieved in that the water content of this memory under tension and Increase in temperature absorbs steam and with a decrease in voltage and temperature steam gives up, the subject matter of the invention has nothing to do with it.
Die Zeichnung stellt die Erfindung dar. Die Kesselbatterie, die beispielsweise aus den dreh Kesseln d und den drei überhitzern b besteht, besitzt den gemeinsamen Rauchgasvorwärmer c und: den gemoinsamen Speisewasserspeicher d. Das Speisewasser wird durch die Kesselspeisepumpe e, durch den Rauchgasvorwärmer c, der auch fehlen kann, durch das Regelorgan f llindürrh dem Speisewasserspeicher d zugeführt. Hier erwärmt es sich durch den Dampf, der dem gemeinsamen Speisewasserspeicher d durch die Leitungen g entweder unmittelbar aus den Kesseln a oder aus der Heißdampflentung h zuströmt. Aus dem Speisewasserspeicher d gelangt das Speisewasser beispielsweise durch die Pumpe i 'in die Spoisewassersammelleitung k, von der aus es den einzelnen Kesseln a durch die Speisewasserregler in in dem Maße, wie Wasser in den Kesseln verdampft wird, zugeführt vviird.The drawing illustrates the invention. The boiler battery, for example consists of the rotating boilers d and the three superheaters b, has the common Flue gas preheater c and: the common feed water storage tank d. The feed water is through the boiler feed pump e, through the flue gas preheater c, which are also missing can be fed to the feed water storage tank d by the control element f llindürrh. here it is heated by the steam that flows through the common feed water storage tank d the lines g either directly from the boilers a or from the superheated steam vent h flows. For example, the feed water arrives from the feed water reservoir d through the pump i 'into the spoil water collecting line k, from which it is the individual Boilers a through the feed water regulator to the same extent as water in the boilers is evaporated, supplied vviird.
