Description

Bei der neuzeitlichen Kalksändsteinfabrikation ist es üblich, die Formlinge in einer Dampffaßanlage mit wechselweise beschickten Dampffässern einer mehrstündigen Dampfhärtung zu unterwerfen. Um beim Chargenwechsel Abdampfverluste aus dem zu entleerenden Dampffaß tunlichst zu vermeiden, ist es bekannt, durch Druckausgleich mit dem neu beschickten Dampffaß den Abdampf zur Aufheizung auszunutzen. Der nach dem Druckausgleich verbleibende Restdampf von i bis 2 atü wurde bisher abgeblasen, da für diese Abwärme wegen des stoßweisen Anfallens im allgemeinen eine wirtschaftliche Ausnutzung nicht möglich ist. Eine wesentlich bessere Wärmeausnutzung läßt sich erfindungsgemäß dadurch erzielen, daß beim Chargenwechsel zur Überführung des Dampfes aus dem zu entleerenden in das neu beschickte Dampffaß die Energie des dem neu beschickten Dampffaß zuströmenden Heizdampfes ausgenutzt wird. Die Überführung des Abdampfes kann so in höherem Maße erreicht werden als durch einfachen Druckausgleich. Außerdem wird die sonst erforderliche Drosselung des Frischdampfes beim Aufheizen durch Expansion und damit Arbeitsleistung ersetzt. Da ferner die Zeit des Aufheizens die Zeit des größten Dampfbedarfs ist, wird durch die Ausnutzung der Abdampfwärme zur Aufheizung die Leistungsspitze fürdenDampferzeuger entsprechend herabgedrückt.In modern sand-lime brick production, it is common to use the Briquettes in a steam barrel system with alternately charged steam barrels one to be subjected to steam curing for several hours. To avoid evaporation losses when changing batches To avoid as much as possible from the steam barrel to be emptied, it is known by pressure equalization to use the exhaust steam for heating with the newly loaded steam barrel. The after Residual steam of 1 to 2 atmospheres remaining after pressure equalization has been blown off so far, since this waste heat is generally an economic one because of the intermittent occurrence Exploitation is not possible. A much better heat utilization can be according to the invention achieve that when changing batches to transfer the steam from the steam barrel to be emptied into the newly charged steam barrel the energy of the newly charged one Steam barrel inflowing heating steam is used. The transfer of the exhaust steam can thus be achieved to a greater extent than by simple pressure equalization. aside from that becomes the otherwise necessary throttling of the live steam during heating by expansion and thus replaces work performance. Furthermore, since the time of heating is the time of the greatest steam requirement is, by utilizing the exhaust heat for heating the power peak for the steam generator is correspondingly lowered.

Die Erfindung sei an einem Ausführungsbeispiel veranschaulicht. Die Abbildung zeigt ein erstes Dampffaß a zur Steinhärtung, dessen Heizvorgang beendet sei, und ein zweites Dampffaß b, das neu mit noch zu härtenden Steinen gefüllt ist. Die Beheizung der Dampffässer mit Frischdampf vom Dampfkessel erfolgt über eine Leitung c mit Abzweigungen d, e zu den einzelnen Dampffässern, in die Absperrorgane f, g eingeschaltet sind. Zur Überführung des Abdampfes aus dem jeweils fertigen Dampffaß ist eine Abdampfleitung h mit Abzweigungen i, k vorgesehen, in die ebenfalls Absperrventile n, m eingeschaltet sind. Diese Abdampfleitung ist über ein Absperrorgan o an einen Strahlverdichter p angeschlossen, der durch den Frischdampf der Leitung c betrieben wird. Durch den Strahlverdichter wird die Restwärme aus dem fertigen Dampffaß a abgesaugt und zusammen mit dem Frischdampf dem neu gefüllten Dampffaß b zugeführt. Nachdem die Restwärme aus dem Dampffaß a in das Dampffaß b übergeführt ist, wird das Dampffaß d über eine Leitung r mit Abzweigungen s, t abgeblasen.The invention is illustrated using an exemplary embodiment. The figure shows a first steam barrel a for stone hardening, the heating process of which has ended, and a second steam barrel b, which is newly filled with stones to be hardened. The steam barrels are heated with live steam from the steam boiler via a line c with branches d, e to the individual steam barrels, in which shut-off devices f, g are switched on. An exhaust line h with branches i, k into which shut-off valves n, m are also switched on is provided for transferring the exhaust steam from the respectively finished steam barrel. This exhaust steam line is connected via a shut-off device o to a jet compressor p, which is operated by the live steam in line c. The jet compressor extracts the residual heat from the finished steam barrel a and feeds it together with the live steam to the newly filled steam barrel b. After the residual heat from the steam barrel a has been transferred to the steam barrel b , the steam barrel d is blown off via a line r with branches s, t.

Es können gegebenenfalls mehrere Strahlverdichter vorgesehen sein, die für verschiedene Treibdampfmengen bemessen sind und nacheinander zur Wirkung kommen, oder es kann ein Strahlverdichter fürveränderlicheTreibdampfmenge vorgesehen sein.If necessary, several jet compressors can be provided, which are dimensioned for different amounts of motive steam and successively to the effect or a jet compressor for a variable amount of motive steam can be provided be.
