Description

Einer weitgehenden Steigerung der Dampfleistung von Hochleistungs-Strahlungskesseln mit natürlichem Wasserumlauf und einer Obertrommel ist durch die hierzu erforderlichen größeren Abmessungen der Obertrommeln eine Grenze gesetzt. Da solche Trommeln aus einem Block nahtlos gewalzt werden, müßten zur Herstellung solcher Trommeln Schmiedepressen von besonders großen Abmessungen entworfen und hergestellt werden, vorausgesetzt, daß entsprechend große Stahlblöcke herstellbar sind. Dementsprechend sind die Herstellungskosten solcher Trommeln so hoch, daß die Wirtschaftlichkeit solcher Hochleistungs-Strahlungskessel größter Leistungsfähigkeit mit natürlichem Wasserumlauf in Frage gestellt wird.A major increase in the steam output of high-performance radiant boilers with natural water circulation and an upper drum is required by this There is a limit to the larger dimensions of the upper drums. Because such drums come out a block are rolled seamlessly, forging presses would have to be used to manufacture such drums are designed and manufactured with particularly large dimensions, provided that that correspondingly large steel blocks can be produced. The manufacturing cost is accordingly such drums so high that the economy of such high-performance radiation boiler greatest efficiency with natural water circulation is called into question.

Die Erfindung betrifft einen Hochleistungs-Strahlungskessel mit natürlichem Wasserumlauf und besteht darin, daß die Steigrohre des zylindrischen oder kegelförmigenFeuerungsraumes oben in ein .zweckmäßig um 45° geneigtes Ringrohr größeren Rohrdurchmessers einmünden. Der sieh im Ringrohr ausscheidende Dampf wird einem Dampfsammler und das sich sammelnde Wasser einem Wassersammler zugeführt.The invention relates to a high-performance radiation boiler with natural Water circulation and consists in that the riser pipes of the cylindrical or conical combustion chamber At the top open into a ring pipe with a larger pipe diameter, suitably inclined at 45 °. The steam that escapes in the ring tube becomes a steam collector and that which collects Water fed to a water collector.

Das Ringrohr nach der Erfindung soll die Aufgabe der bisherigen Trommeln mit Bezug auf die Ausdampfung übernehmen und ferner als Verbindungsstück für die Dampf- und Wasseranschlüsse zu den anderen Kesselaggregaten dienen.The ring tube according to the invention is intended to do the job of the previous drums take over with reference to the evaporation and also as a connector for the Steam and water connections to the other boiler units are used.

Bisher ist davon ausgegangen worden, daß der Grad der Ausdampfung allein von der Größe der in der Trommel vorhandenen Wasseroberfläche abhängig ist. Die Erfindung macht sich demgegenüber die Erkenntnis zunutze, daß der Grad der Ausdampfung nicht allein von der im Sammelaggregat vorhandenen Wasseroberfläche abhängig ist, sondern von der Menge des in den Steigrohren verdampfenden Wassers. Es muß also bei der Anwendung der Erfindung dafür Sorge getragen werden, daß der Feuerraum eine Ausbildung erfährt, die gewährleistet, daß in den Steigrohren verhältnismäßig viel Wasser in Dampf verwandelt wird, so daß man mit einer geringen Ausdampfungsoberfläche auskommen kann.So far it has been assumed that the degree of evaporation depends solely on the size of the water surface in the drum. In contrast, the invention makes use of the knowledge that the degree of evaporation does not depend solely on the water surface in the collection unit, but on the amount of water evaporating in the riser pipes. So it must be taken care of when applying the invention that the furnace a Experiences training that ensures that there is a relatively large amount in the riser pipes Water is converted into steam, so that one with a small evaporation surface can get along.

Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt.The invention is shown in the drawing in an exemplary embodiment.

Die Abbildung zeigt einen Hochleistungs-Strahlungskessel im senkrechten Längsschnitt. Der dargestellte Kessel besitzt zwei Schmelzkammern a und b mit Zvklonfeuertulg und einem sich daran anschließenden Feuerraum c mit kreisförmigem Querschnitt. Der Feuerraum a, b, c wird in üblicher Weise durch Steigrohre d gebildet, die erfindungsgemäß oben in den Ring e mit größerem Rohrdurchmesser, etwa 300 bis 500 min, einmÜnden. In diesem Ring e sammelt sich Dampf und Wasser aus den Steigrohren und aus dem vom Ekonomiser f zugeführten l@ainpf-`Vasser-Gemisch. Der sich in dem Ringe ausscheidende Dampf wird dem Dampfsammler g zur Weiterleitung an den Überhitzer h und i und das sich sammelnde Wasser dem Wassersammler k zur Weiterleitung an die Fallrohre l zugeführt.The illustration shows a high-performance radiation boiler in a vertical longitudinal section. The boiler shown has two melting chambers a and b with a Zvklonfeuertulg and an adjoining furnace c with a circular cross-section. The combustion chamber a, b, c is formed in the usual way by riser pipes d which, according to the invention, open at the top into the ring e with a larger pipe diameter, about 300 to 500 min. In this ring e, steam and water from the riser pipes and from the l @ ainpf-`Vasser mixture supplied by the economizer f collect. The steam that separates out in the ring is fed to the steam collector g for forwarding to the superheaters h and i and the water that collects is fed to the water collector k for forwarding to the downpipes l.
