Description

Die Erfindung bezieht sich auf Dampferzeuger und befaßt sich insbesondere mit der Trocknung des in der Dampfmaschine teilentspannten Dampfes.The invention relates and is particularly concerned with steam generators with the drying of the steam, which has been partially expanded in the steam engine.

Sie besteht darin, daß im Dampferzeuger nielirere selbständige Überhitzer vorgesehen sind, von (leiten mindestens einer für die Hochüberhitzung einer Teilmenge des erzeugten Arbeitsdampfes ausgelegt ist. Nf-fan kann dies durch entsprechende Bemessung und/oder Hintereinanderschaltung der Überhitzer erreichen. Der so nachNlenge undTemperattir gestaffelt überhitzte Dampf wird der Dampfmaschine in der Weise zugeführt, daß der der Maschine mit relativ geringer Temperatur zugeführte und in ihr teilentspannte Dampf durch den hochüberhitzten Dampf getrocknet wird.It consists in the fact that there are fewer independent superheaters in the steam generator are provided, of (direct at least one for the high overheating of a subset of the working steam generated is designed. Nf-fan can do this with the appropriate Achieve dimensioning and / or series connection of the superheaters. The so lenient undTemperattir staggered superheated steam is fed to the steam engine in such a way that the machine fed at a relatively low temperature and partially relaxed in it Steam is dried by the superheated steam.

Die Zeichnung zeigt skizzenhaft ein Ausführungsbeispiel.The drawing shows a sketch of an embodiment.

Im Rauchgaszug des Wasserrohrkessels B liegen zwischen den Steig- und Fallrohren die beiden Überhitzer a und b, die zu einer baulichen Einheit zusammengeschlossen sein können. Ein Teil des Dampfes aus der Obertrommel c strömt durch den Überhitzer a, die Restmenge durch den Cberhitzer b. Man kann jedoch auch die gesamte Dampfmenge zuerst durch den Überhitzer a leiten, von dem hier überhitzten Dampf eine Teilmenge abspalten und dem Cberhitzer b zur weiteren überhitzung zuführen, wie in der Zeichnung durch strichpunktierte bzw. gestrichelte Linien angedeutet ist. Der Ü berhitzer a ist für die Überhitzung der Hauptmenge, etwa 8o bis 9o °/o des erzeugten Dampfes, auf 33o° C, der Überhitzer b für die Überhitzung der Restmenge, etwa io bis 20 %, auf .420° C ausgelegt. Der Dampf von nur 330° C aus dem Cberhitzer a strömt dem Hochdruckzylinder d der Dreifachexpansionsmaschine A zu, wäh- rend die im Cl)erllltzer b atlf 420° C gebrachte Teilmenge <lern teilentspannten Arbeitsdampf zwi- schen (lern \litteldrtickzvlincler c und dein Nieder- druckz_ylinder f in einer zum Trocknen genügenden Menge zugeleitet wird. Analog ist eine T rockiitilig des teilentspannten Arbeitsdampfes durch den 1111 Überhitzer b hochüberhitzten Dainpf auch vor einer früheren und/oder späteren Entspannungsstufe, z. B. eine Abdampfturbine, mdglicli. In gleicher Weise läßt sich naturgemäß mit den offenbarten Mitteln auch der Dainpf vor den Druck- stuten einer Kreiselmaschine trocknen. In the flue gas duct of the water tube boiler B, the two superheaters a and b, which can be combined to form a structural unit, are located between the riser and downpipes. Part of the steam from the upper drum c flows through the superheater a, the remainder through the superheater b. However, you can also first pass the entire amount of steam through the superheater a, split off a portion of the steam superheated here and feed it to the superheater b for further superheating, as indicated in the drawing by dash-dotted or dashed lines. The superheater a is designed to superheat the main amount, about 8o to 9o% of the generated steam, to 33o ° C, the superheater b is designed to superheat the remaining amount, about 10 to 20%, to .420 ° C. The steam of only 330 ° C from the superheater a flows to the high-pressure cylinder d of the triple expansion machine A, while rend the in the Cl) erllltzer at 420 ° C Partial amount <learn partially expanded working steam between (learn \ litteldrtickzvlincler c and your lower pressure cylinder f in a sufficient for drying Amount is fed. Analog is a T rockiitilig of the partially expanded working steam through the 1111 Superheater b highly superheated Dainpf also in front of a earlier and / or later relaxation stage, z. B. an exhaust turbine, mdglicli. In the same way, of course, the disclosed means also the Dainpf before the printing drying mares on a spinning machine.
