  Betriebsverfahren für Dampfkesselanlagen mit Wärmespeichern und   RauchgasvorwÅarmern.   



   Die Erfindung bezieht sich auf   Kesselanlagen mit Aufspeicherung von   heissem Kesselwasser bei geringer Dampfentnahme und Verminderung oder Unterbrechung der Speisung bei mehr   Damip-   entnahme. 



   Bei diesen Anlagen ist vorgeschlagen worden, bei Unterbrechung der Speisung das durch den Ekonomiser fliessende Wasser in einem besonderen Speisewasserspeicher aufzuspeichern und es nachher bei Normalbetrieb dem   Kessel wieder zuzuführen.   



   Diese Anordnung hat insofern einen Nachteil, als die dem durch den   Ekonomiser fliessenden Wasser     übertragene Wärme   zur Dampferzeugung während der Überlastung des Kessels nicht ausgenutzt werden

   Im   Umführungskanal   ist eine grössere Anzahl Rohre 7 vorgesehen, die unten in einen Kasten 8 münden, der seinerseits durch einen Kanal 9 mit der Unterseite des Rostes verbunden ist. Der vordere Teil des Rostes ist durch eine Einkapselung 10 gegen die Aussenluft abgesperrt. Bei Normalbetrieb sind die   Klappen 3 geöffnet   und die Klappen 6 geschlossen, so dass die Rauchgase durch die   Ekonomiser   hindurch abgesaugt werden und das Speisewasser anwärmen. Wird aber die Speisung unterbrochen, so werden die Klappen : j geschlossen und die Klappen 6 geöffnet, so dass die Rauchgase durch den durch die Rohre 7 gebildeten Luftvorwärmer hindurchströmen und zum Saugzug gelangen.

   Die Verbrnnungsluft wird durch die Rohre 7 hindurch angesaugt und dabei   angewärmt und gelangt   dann durch die Leitung 9 unter den Rost des   Kessels 1,   wo sie dann nach Durchdringen der   Brennstoffschicht   durch ihre erhöhte Temperatur auch eine Erhöhung der Verbrennungstemperatur in der Kesselanlage hervorruft.

  Operating procedures for steam boiler systems with heat storage and flue gas preheaters.



   The invention relates to boiler systems with accumulation of hot boiler water with little steam extraction and reduction or interruption of the supply with more steam extraction.



   In these systems it has been proposed to store the water flowing through the economizer in a special feed water reservoir when the feed is interrupted and to feed it back to the boiler afterwards during normal operation.



   This arrangement has a disadvantage in that the heat transferred to the water flowing through the economizer is not used to generate steam when the boiler is overloaded
 EMI1.1
 



   In the drawing, the invention is shown in one embodiment, u. between shows: FIG. 1 a vertical longitudinal section through such a boiler system and FIG. 2 a plan view.



   Behind the boiler 1, a divided economizer 2, 2 'is provided through which the flue gases by means of
 EMI1.2
 



   In the bypass channel, a larger number of tubes 7 are provided, which open below into a box 8, which in turn is connected by a channel 9 to the underside of the grate. The front part of the grate is closed off from the outside air by an encapsulation 10. During normal operation, the flaps 3 are open and the flaps 6 are closed, so that the flue gases are sucked off through the economizers and heat the feed water. If, however, the supply is interrupted, the flaps: j are closed and the flaps 6 are opened, so that the flue gases flow through the air preheater formed by the pipes 7 and reach the induced draft.

   The combustion air is sucked in through the pipes 7 and warmed up and then passes through the line 9 under the grate of the boiler 1, where, after penetrating the fuel layer, its increased temperature also causes the combustion temperature in the boiler system to increase.
