Description

Die Erfindung betrifft einen Strahlungskessel für große Leistungen mit zwei Obertrommeln, von denen jede einen eigenen Speisewasservo.rwärmer und ein von der anderen Trommel völlig getrenntes, aber gemeinsam beheiztes Wasserumlaufsystem besitzt.The invention relates to a radiation boiler for high outputs with two head drums, each of which has its own feed water servo Water circulation system that is completely separate from the other drum, but is jointly heated owns.

Gemäß der Erfindung werden die Steigrohre beider Wasserumlaufsysteme abwechselnd nebeneinander in der gemeinsamen Brennkammer angeordnet. Der Überhitzer ist nach der Erfindung in an sich bekannter Weise an beide Obertrommeln oder an jedeObertrommel gesondert angeschlossen, wobei die Trommeln in gleicher oder verschiedener Höhe liegen können.According to the invention, the risers of both water circulation systems arranged alternately next to each other in the common combustion chamber. The superheater is according to the invention in a manner known per se on both upper drums or on each top drum connected separately, with the drums in the same or different Height can be.

Bei Kesseln mit zwei Obertrommeln ist es bereits bekannt, jeder Obertrommel ihr eigenes Wasserumlaufsystem zuzuordnen, wobei aber im Gegensatz zum Erfindungsgegenstand für jedes Umlaufsystem eine gesonderte, unabhängig beheizte Brennkammer vorgesehen ist.It is already known for boilers with two upper drums, each upper drum to assign their own water circulation system, but in contrast to the subject of the invention a separate, independently heated combustion chamber is provided for each circulation system is.

Diese Kesselausführung hatte aber den Nachteil, daß eine gleichmäßige Beheizung der beiden getrennten Kesselumlaufsysteme außerordentlich schwierig, wenn nicht gar unmöglich war. Infolge der damit verbundenen unterschiedlichen Dampferzeugung der beiden Umlaufsysteme war auch die Regelung der Speisewasserzufuhr und die Einhaltung der gewünschten Heißdampftemperatur und des gewünschten Austrittsdruckes sehr erschwert.However, this boiler design had the disadvantage that a uniform Heating of the two separate boiler circulation systems extremely difficult, if wasn't impossible at all. As a result of the associated different steam generation of the two circulation systems was also the regulation of the feed water supply and compliance the desired superheated steam temperature and the desired outlet pressure is very difficult.

Ein weiterer Nachteil des bekannten Kessels bestand auch darin, daß der bauliche Aufwand für zwei getrennte Brennkammern sehr groß war.Another disadvantage of the known boiler was that the structural effort for two separate combustion chambers was very large.

Nach der Erfindung werden alle diese Nachteile und Schwierigkeiten mit Sicherheit beseitigt. Der Erfindungsgegenstand hat unter anderem auch noch den Vorteil, daß sich stets ein gleichmäßiger und ruhiger Wasserspiegel in den einzelnen Obertrommeln einstellt. Außerdem kann eine gleichmäßige Regelung erzielt werden. Obwohl jede Trommel für sieh ein getrenntes Wasserumlaufsystem besitzt, können die für jede Trommel zugehörigsn Steigrohre in eine gemeinsame Brennkammer verlegt werden.The invention eliminates all of these drawbacks and difficulties eliminated with certainty. The subject of the invention also has the Advantage that there is always an even and calm water level in the individual Top drums adjusts. In addition, uniform regulation can be achieved. Although each drum has its own separate water circulation system, the For each drum associated riser pipes are laid in a common combustion chamber.

Der Erfindungsgegenstand gestattet es auch, die Obertrommeln in gleicher oder verschiedener Höhenlage anzuordnen. In der Zeichnung ist schematisch ein Ausführungsbeispiel gemäß der Erfindung dargestellt.The subject of the invention also allows the upper drums in the same or at different altitudes. An exemplary embodiment is shown schematically in the drawing shown according to the invention.

Mit i und 2 sind die beiden Obertrommeln der Kesselanlage bezeichnet, von welchen die Obertrommel i ihr Speisewasser von dem Speisewasservorwärmer 3 über die Leitung q. und die Obertrommel 2 ihr Speisewasser von dem Speisewasservorwärmer 5 über die Leitung 6 erhält. Der Zufluß des Speisewassers zum Speisewasservorwärmer 3 erfolgt über das Ventil 7, das zur Regelung der Zuflußmenge mit einer Impulsleitung 8 mit der Obertrommel i verbunden ist. Der Zufluß zum Speisewasservorwärmer 5 erfolgt auf dieselbe Weise über Ventil 9 mit der Impulsleitung io.The two upper drums of the boiler system are denoted by i and 2, of which the upper drum i transfers its feed water from the feed water preheater 3 the line q. and the top drum 2 its feed water from the feed water preheater 5 receives over line 6. The inflow of the feed water to the feed water preheater 3 takes place via the valve 7, which is used to regulate the inflow quantity with an impulse line 8 is connected to the upper drum i. The inflow to the feedwater preheater 5 takes place in the same way via valve 9 with the impulse line io.

Von der Obertrommel i gelangt das eingespeiste Wasser über in der Zeichnung nicht dargestellte Fallrohre in den Sammler i i. Von dem Sammler i i gehen die Steigrohre 12 ab, die die Kesselwände der Brennkammer 13 kühlen und alle in die Obertrommel i münden. Die Obertrommel 2 ist mit dem Sammler 1.4 du-roh in der Zeichnung nicht dargestellte Fallrohre verbunden. Die vom Sammler 14 ausgehendem Steigrohre 15 sind ebenfalls an den Kesselwänden der Brennkammer 13 verlegt und münden dann in die Obertrommel 2.From the upper drum i, the water fed in passes over in the Drawing not shown downpipes in the collector i i. From the collector i i go the risers 12, which cool the boiler walls of the combustion chamber 13 and all in the top drum i open. The upper drum 2 is with the collector 1.4 du-raw in the Drawing not shown downpipes connected. The outgoing from the collector 14 Riser pipes 15 are also laid on the boiler walls of the combustion chamber 13 and then flow into the upper drum 2.

Der in den Obertrommeln i und 2 befindliche Sattdampf wird über die Leitungen 16 bzw. 17 in einen Sammler 18 geleitet, von wo er in den Überhitzer i9 gelangt.The saturated steam in the upper drums i and 2 is via the Lines 16 and 17 passed into a collector 18, from where it is fed into the superheater i9 got.
