Description

Dampfüberhitzer, bestehend aus zwei hintereinandergeschalteten Heizflächen mit zwischengeschaltetem, als Oberflächenkühler ausgebildetem Temperaturregler Die Erfindung betrifft eine neue Anordnung eines aus zwei oder mehreren Gruppen bestehenden Überhitzers, bei denen zwischen den Gruppen ein als Oberflächenkühler ausgebildeter Temperaturregler eingeschaltet ist. Diese Einrichtungen besitzen jedoch den Nachteil, daB eine genaue Regelung der Temperatur nicht möglich ist, weil der gesamte Dampf die nachgeordneten Gruppen durchströmen muB.Steam superheater, consisting of two heating surfaces connected in series with an interposed temperature controller designed as a surface cooler Die The invention relates to a new arrangement of one consisting of two or more groups Superheater, in which a surface cooler is formed between the groups Temperature controller is switched on. However, these facilities have the disadvantage that an exact regulation of the temperature is not possible because of all the steam the subordinate groups must flow through.

Demgegenüber besteht das Wesen der Erfindung darin, daB in der Verbindungsleitung zwischen zwei hintereinanderliegenden überhitzergruppen ein Regelungsventil eingeschaltet ist, das gestattet, den Dampf unter Umgehung des Temperaturreglers ganz oder teilweise von der ersten in die zweite Überhitzergruppe zu leiten.In contrast, the essence of the invention is that in the connecting line A control valve is switched on between two superheater groups lying one behind the other is allowed to use the steam in whole or in part by bypassing the temperature regulator from the first to the second superheater group.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.

Der Überhitzer eines Dampferzeugers besteht aus den beiden Gruppen d und b. Beide Gruppen besitzen die oberen Sammelbehälter c, die durch eine Scheidewand d getrennt sind, und die unteren Sammelbehälter e, die durch ein Regelorgan f miteinander in Verbindung stehen.The superheater of a steam generator consists of the two groups d and b. Both groups have the upper collecting container c, which is through a partition d are separated, and the lower collecting tank e, which is connected to one another by a control element f stay in contact.

Durch die Ausbildung des überhitzers in der vorerwähnten Art ergeben sich für die 'Regelung der Temperatur fies überhitzten Dampfes folgende Möglichkeiten: Der vom Dampferzeuger g kommende Sattdampf wird durch die Leitung h nach dein Überhitzer a geleitet und wird nun bei völlig geschlossenem Regelorgan f durch die Leitung k nach dem im Oberkessel befindlichen Rückkühler l und -von der zu dem zweiten Überhitzer b durch die Leitung in geführt, um zur Dampfentnahme i zu gelangen.The design of the superheater in the aforementioned type results in the following options for regulating the temperature of nasty superheated steam: The saturated steam coming from the steam generator g is passed through the line h to your superheater a and is now through the line with the control element f completely closed k after the recooler l located in the upper boiler and from which to the second superheater b through the line in to get to the steam extraction i.

Wird dagegen das Ventil f ganz oder teilweise geöffnet, so kann der Dampf unter Umgehung des Reglers L ganz oder teilweise zur zweiten Überhitzergruppe- gelqngen: -@;If, on the other hand, the valve f is fully or partially opened, the can Steam to the second superheater group in whole or in part by bypassing the L succeed: - @;
