Description
Naturumlauf-Dampferzeuger mit aus Schrägrohrgruppen gebildeter Berührungsheizfläche Die Erfindung betrifft einen Naturumlauf-Dampferzeuger mit einer Berührungsheizfläche, die aus mindestens zwei im Gaszug schräg und im Rauchgasstrom hintereinanderliegend angeordneten Rohrgruppen besteht, deren einzelne Rohre parallel zueinander liegen und im Kühlmittelkreislauf parallel geschaltet sind und jeweils von eigenen lotrechten oder annähernd lotrechten Verteilern ausgehen und in ebenso angeordnete Sammler einmünden, wobei die Rohrgruppen für sich an einen oberhalb der Rohrgruppen quer zu diesen liegenden Zwischensammler derart angeschlossen sind, daß die Einmündungen der Rohrgruppensammler in den Zwischensammler für die schwächer beheizten Rohrgruppen höher liegen als die Einmündungen der stärker beheizten Rohrgruppen, wobei der Zwischensammler mit Verteilern für beheizte Rohrgruppen durch unbeheizte, am unteren Scheitel des Zwischensammlers angeschlossene Rücklaufrohre verbunden ist, nach Patent 1185 197.Natural circulation steam generator with contact heating surface formed from groups of inclined pipes The invention relates to a natural circulation steam generator with a contact heating surface, which consists of at least two pipe groups inclined in the gas flue and one behind the other in the flue gas flow, the individual pipes of which are parallel to one another and are connected in parallel in the coolant circuit and each of their own vertical or approximately vertical distributors and open into collectors arranged in the same way, the tube groups being connected to an intermediate collector located above the tube groups transversely to these in such a way that the junctions of the tube group collector in the intermediate collector for the less heated tube groups are higher than the junctions of the more heated pipe groups, the intermediate header being connected to distributors for heated pipe groups by unheated return pipes connected to the lower apex of the intermediate header, according to Pa tent 1185 197.
Bei der Ausbildung nach dem Hauptpatent liegen die beiden Ableitungsrohre der Schrägrohrbündel mit Abstand voreinander. Dies führt zu Schwierigkeiten bei der Ausbildung der Kesselwand, an der diese Rohre nach oben zum gemeinsamen Sammler geführt sind.In the training according to the main patent, the two discharge pipes are located the inclined tube bundle at a distance from each other. This leads to difficulties the formation of the boiler wall on which these pipes go up to the common collector are led.
Aufgabe der Erfindung ist es, diesen Nachteil zu beheben. Hierzu wird für einen Naturumlauf-Dampferzeuger der eingangs genannten Gattung erfindungsgemäß vorgeschlagen, daß die Sammelrohre der unteren Rohrgruppe in an sich bekannter Weise konzentrisch durch die Sammelrohre der oberen Rohrgruppe zum gemeinsamen oberen Sammler geführt sind. Auf diese Weise wird die Ausbildung der betreffenden Kesselwand nicht behindert oder erschwert, und die Ausbildung der Rohrgruppensammler sowie deren Anschluß an den oberen Sammler werden begünstigt.The object of the invention is to remedy this disadvantage. This is done according to the invention for a natural circulation steam generator of the type mentioned at the beginning proposed that the headers of the lower tube group in a known manner concentrically through the header pipes of the upper pipe group to the common upper one Collectors are led. In this way, the formation of the boiler wall in question not hindered or made difficult, and the training of the pipe group collector as well their connection to the upper collector is favored.
Die Anordnung eines Ableitungsrohres für tief gelegene Rohre eines Schrägrohrbündels innerhalb einer Teilkammer, in welche höher liegende Schrägrohre einmünden, ist an sich bekannt.The arrangement of a drainage pipe for deep pipes of a Inclined tube bundle within a sub-chamber, in which higher inclined tubes run into is known per se.
Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes in einer Ansicht.The drawing shows an embodiment of the subject matter of the invention in one view.
Die Berührungsheizfläche besteht aus einer unteren Rohrgruppe 1 und einer oberen, gegenüber der unteren stärker beheizten Rohrgruppe 2. Die Schrägrohre der einzelnen Rohrgruppen gehen von den senkrechten Verteilern 5 und 6 aus, welche mit den Querverteilern 3 und 4 verbunden sind. Die Schrägrohre münden in die Rohrgruppensammler 7 und 9 ein, welche an den Quersammler 8 angeschlossen sind. Erfindungsgemäß sind die Sammelrohre 7 konzentrisch innerhalb der Rohre 9 angeordnet. Hierzu haben die Rohre 9 einen größeren Durchmesser. An ihrem unteren Ende sind sie eingezogen und mit den Rohren 7 verschweißt. Die Rohre 7 der schwächer beheizten Rohrgruppe münden höher als die Rohre 9 im Sammler 8 aus.The contact heating surface consists of a lower group of tubes 1 and an upper tube group 2, which is more heated than the lower one. The inclined tubes of the individual tube groups go from the vertical distributors 5 and 6, which with the cross distributors 3 and 4 are connected. The inclined pipes lead into the pipe group collector 7 and 9, which are connected to the cross collector 8. Are according to the invention the header pipes 7 are arranged concentrically within the pipes 9. To do this, the Tubes 9 have a larger diameter. At their lower end they are drawn in and welded to the tubes 7. The tubes 7 of the less heated tube group open higher than the tubes 9 in the collector 8.
