Description
tritt am unteren Ende des rohrförmigen Mantels 5 außerhalb des Behälters 1 liegt, wird über die Länge b der von den Heizschlangen 6 gebildeten Heizfläche eine Auskühlung des Heizmittels erreicht, bevor dieses über eine Rücklaufleitung 02 in das Netz zurückströmt Das Maß dieser Auskühlung kann durch entsprechende Bemessung der Länge b der Heiziläche eingestellt werden.occurs at the lower end of the tubular jacket 5 outside the container 1, the heating medium is cooled over the length b of the heating surface formed by the heating coils 6 before it flows back into the network via a return line 02.The extent of this cooling can be determined by appropriate measurement the length b of the heating surface can be set.
Das in dem Raum 17 befindliche Speisewasser wird durch die übrige Heizfläche der Rohrschlangen 6 ι η aufgeheizt und schließlich zum Verdampfen gebracht. Das dabei erzeugte Dampf-Wasser-Gemisch gelangt über die oberhalb des Speisewasserspiegels 17 liegende, sich trichterförmig erweiternde Mündung des rohrförmigen Mantels 5 in einen als Dampfdom wirkenden Raum 19 des Behälters 1, vo won aus sich das unverdampfte Kesseiwasser nach unten absetzt, während der Dampf über den Dampf-Austrittsstutzen 2 und die Leitung 04 abströmtThe feed water located in the space 17 is ι η through the remaining heating surface of the pipe coils 6 heated up and finally made to evaporate. The resulting steam-water mixture arrives via the funnel-shaped widening mouth of the tubular, located above the feed water level 17 Shell 5 in a acting as a steam dome space 19 of the container 1, vo won from the unevaporated boiler water settles down while the steam flows out via the steam outlet connection 2 and the line 04
Der dem Speisewasser zugeordnete Raum 18 des Behälters 1 steht über die Speisewasser-Eintrittsöffnungen 12 mit dem von dem rohrförmigen Mantel 5 umschlossenen Raum 17 in Verbindung. Dadurch entsteht ein zusätzlicher Umlauf des Speisewassers, weil dieses über die Eintrittsöffnungen 12 wieder in den rohrförmigen! Mantel 5 eintritt und in dem Raum 17 der Verdampfung zugeführt wird. Die sich dadurch ergebende Turbulenz erhöht die Leistungsdichte des Dampferzeugers.The space 18 of the container 1 assigned to the feed water stands above the feed water inlet openings 12 with the space 17 enclosed by the tubular jacket 5 in connection. Through this there is an additional circulation of the feed water because it is returned to the via the inlet openings 12 tubular! Jacket 5 enters and is supplied to the evaporation in the space 17. The resulting Turbulence increases the power density of the steam generator.
In einer nicht dargestellten Ausführungsform ist es 3« auch denkbar, den Eintrittsöffnungen 12 wenigstens eine Umwälzpumpe zuzuordnen, um damit eine Zwangsumwälzung des in dem Raum 18 befindlichen Speisewassers zu erzielen.In an embodiment not shown, it is 3 « it is also conceivable to assign at least one circulating pump to the inlet openings 12 in order to achieve a To achieve forced circulation of the feed water located in the space 18.
Während bei dem dargestellten Ausführungsbeispiel des Dampferzeugers lediglich ein rohrförmiger Mantel 5 mit darin angeordneten Heizschlangen 6 vorhanden ist, sind auch Anlagen denkbar, bei denen in einem Behälter 1 mehrere derartiger, jeweils von einem rohrförmigen Mantel 5 umschlossener, durch Heizschlangen oder dgl. gebildeter Heizvorrichtungen vorhanden sind. Auch kann sowohl in dem Raum 17 als auch in dem Raum 18 eine Zusatzheizeinrichtung vorgesehen sein, um die Dampferzeugung zu intensivieren bzw. um das Speisewasser vor der eigentlichen Verdampfung noch vorzuheizen.While in the illustrated embodiment of the steam generator only a tubular jacket 5 is present with heating coils 6 arranged therein, systems are also conceivable in which in one Container 1 several such, each enclosed by a tubular jacket 5, by heating coils Or the like. Formed heating devices are present. Also in the room 17 as an additional heating device can also be provided in space 18 in order to intensify the generation of steam or to preheat the feed water before the actual evaporation.
Die Niveauhöhe des Speisewassers in dem Behälter 1 kann bei 16 abgelesen werden; dem Behälter 1 kann ohne weiteres eine ebenfalls nicht weiter veranschaulichte Niveauregelung zugeordnet werden, die durch entsprechende Regelung der über die Leitung 03 erfolgenden Speisewasserzufuhr die Niveauhöhe des Speisewassers in dem Behälter 1 konstant hält.The level of the feed water in the container 1 can be read off at 16; the container 1 can can easily be assigned a level control, which is also not further illustrated, by corresponding regulation of the feed water supply taking place via line 03, the level of the Keeps feed water in the container 1 constant.
Der in der Figur mit a bezeichnete Abstand zwischen der Mündung des rohrförmigen Mantels 5 und der oberen den Raum 19 begrenzenden Wand des Behälters 1 kann — gegebenenfalls gemeinsam mit der mit b bezeichneten Länge der zur Auskühlung des Heizmittels dienenden Heizfläche der Heizschlangen 6 — derart gewählt werden, daß der Dampfzustand die Leistung und die Auskühlung des Heizmittels den jeweils geforderten Betriebsbedingungen optimal angepaßt sind.The designated in the figure by a distance between the mouth of the tubular shell 5 and the upper space 19 delimiting wall of the container 1 can - be selected such - optionally together with the b designated length of the serving for the cooling of the heating medium heating surface of the heating coils 6 that the steam condition, the performance and the cooling of the heating medium are optimally adapted to the required operating conditions.

Aus der Vorlaufleitung 01 strömt Heizmittel, beispielsweise Dampf, über den Heizmittel-Eintrittsstutzen 9 und die Rohre 7 in die Heizschlangen 6 ein. Das Heizmittel überträgt dabei die Wärme auf das in dem von dem rohrförmigen Mantel 5 umschlossenen Raum 17 enthaltene Speisewasser, das aus der Leitung 03 über den Stutzen 14 im Gegenstrom zu dem Heizmittel in den Raum 17 eingespeist wird. Da der Speisewasserein-This steam generator works as follows:
Heating medium, for example steam, flows from the flow line 01 via the heating medium inlet connection 9 and the pipes 7 into the heating coils 6. The heating means transfers the heat to the feed water contained in the space 17 enclosed by the tubular jacket 5, which feed water is fed into the space 17 from the line 03 via the connection 14 in countercurrent to the heating means.
