Description

Dampfüberhitzer. Fs ist bei Dampfüberhitz.ern bekannt, den lichten Quemclinitt der zur Führung des zu überhitzenden Dampfes -dienenden Rohrelemente vorn Sattdampfeintritt bis zum Heißdampfaustritt entsprechend dem durch die überlützung zunehmenden Dampfvolumen in der Weise zu erweitern, daß in allen Teilen: der Rohrelemente gleiche bzw. annähernd. gleiche Dampfgeschwindigkeit herrscht. Die Ausbildung solcher Rohrelemente erfolgte bisher in ,der Weise, .daß Rohre von verschieden lichter Weite aneinandergesetzt würden. Diese Ausführung der Rohrelemente wies aber die Nachteile auf, daß infolge der Verbindung der Rohre von verschieden großem Durchmesser die Herstellung der Rohrelemente seIx teuer «.urde und mit großen Schwierigkeiten ,;t-rknüpft war und außerdem für die Verbinc1-m-"- der Rohrelemente mit den zur Aufnahme des Sattdampfes bestimmten Sammelrohre andere Rohranschlüsse als bei dem zur Aufnahme des Heißdampfes dienenden Sammelrohre notwendig wurden. Die Erfindung bezweckt nun, diese Nachteile zu beseitigen. Der Zweck wird nach der Erfindung dadurch erreicht, daß jedes Rohrelement aus nur einem einzigen Rohr von überall .gleichem Durchmesser besteht, dessen einzelne Rohrstränge um so mehr flachgepreßt sind, je näher sie der Dampfeintrittsstelle liegen.Steam superheater. This is known from steam overheaters, the light ones Cross-section of the pipe elements used to guide the steam to be superheated from the saturated steam inlet to the superheated steam outlet according to the overlap increasing steam volume in such a way that expand in all parts: the tubular elements same or approximately. the same steam speed prevails. The training of such Up to now, pipe elements have been carried out in such a way that pipes of different clear widths would be put together. However, this design of the tubular elements had the disadvantages on that as a result of the connection of the pipes of different diameters Manufacture of the tubular elements is extremely expensive ". It was linked with great difficulty and with great difficulty was and also for the Verbinc1-m - "- of the pipe elements with the to accommodate the Saturated steam certain collecting pipes different pipe connections than in the case of the intake of the superheated steam serving collecting pipes became necessary. The invention now aims to eliminate these disadvantages. According to the invention, the purpose is achieved by that each pipe element consists of a single pipe of the same diameter everywhere consists, whose individual pipe strings are pressed flat the closer they are the steam entry point.

Auf der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes dargestellt, und zwar zeigt A.bb. i ein Rohrelement in, Verbindung mit den Sammelbehältern und A:bb. a bis 5 in größerem 14Taßstabe einen Schnitt durch j e einen Rohrstrang des Rohrelements. ES bezeichnet a das Sammelrohr zur Aufnahme de Sattdampfes und b das Sammelrohr zur Aufnahme des Heißdampfes (Abb. i). Die Sammelrohre a und b stehen durch Rohrelemene (überhitzerrohre) miteinander in Verbindung. jedes Rohrelement besitzt acht Rohrstränge, die in der Abb. i mit I bis VIII bezeichnet sind, und um so mehr flachgepreBt siäd; je näher sie der Dampfeintrittsstelle Iiegen, so &ß ider Durchflußquexsohnitt :der Rohrstränge sich: nach dem, zur Aufnahme des Heißdampfes dienenden Sammelrohre b hin erweitert (siehe besonders Abb-. z bis 5). Die Abflachung der einzelnen Rohrstränge erfolgt in .dem Verhältnis, da.ß in allen Rohrsträngen entsprechend der Volumänderung des durch sie strömenden Dampfes in .dem Rohrelement von zier Dampfeintrittsstelle bis zur Dampfaustrittsstelle eine gleiche oder annähernd gleiche Dampfgeschwindigkeit herrscht. Die Rohrelemente behalten an dien Bogen oder Umkehrstellen, an denen an sich bereits die Strömungsgeschwindigkeit des Dampfes Sehemmt wird., ihren runden; Querschnitt bei, ebenfalls sind an ,den Stellen, an denen das Rohrelement mit den Sammelbehältern a und b in Verbindung steht, die Rohre rund gelassen, so daß die Rohranschlüsse an beiden Sammelrohren gleich ausgeführt werden können.The drawing shows an embodiment of the subject matter of the invention shown, namely A.bb. i a pipe element in connection with the collecting tanks and A: bb. a to 5 on a larger scale 14 a section through each pipe string of the pipe element. ES denotes a the collecting pipe for receiving de Saturated steam and b the collecting pipe for taking up the superheated steam (Fig. I). The manifolds a and b are connected to one another by means of tube elements (superheater tubes). each Pipe element has eight pipe strings, which are designated in Fig. I with I to VIII are, and all the more flattened; the closer they are to the steam entry point, so & ß ider Durchflußquexsohnitt: the pipe strings themselves: after, to the intake of the superheated steam serving manifolds b expanded (see especially Fig. z to 5). The flattening of the individual pipe strings takes place in the ratio that in all pipe strings according to the change in volume of the steam flowing through them in .the pipe element from the decorative steam entry point to the steam outlet point the same or approximately the same steam speed prevails. Keep the pipe elements at the bends or turning points, where the flow velocity is already in itself the steam is inhibited., their round ones; Cross-section at, are also on, the Places where the pipe element with the collecting tanks a and b in connection stands, the pipes left round so that the pipe connections on both manifolds can be executed immediately.
