Description

Steam superheater, wholly or partially made of corrugated pipe The invention relates to a steam superheater. which contrary to the known statements by the peculiar use of corrugated pipes.

The subject matter of the invention is shown, for example, in the drawing. '-Fig. i shows the longitudinal section of one embodiment. while Fig. 2 shows the cross section along line AB of Fig. i. - '# bb. 3 illustrates another embodiment and FIG. 4 the associated cross-section: Z, according to line CD in FIG. 3. Fig. 5 and 6 show in longitudinal section further variants of the subject matter of the invention - The Cberbityer according to -, &# bb. i and 2 consists of the corrugated tube a, into which the corrugated roller b is inserted in such a way that the troughs of the inner roller and the crests of the outer tube form self-contained hollow rings c. Every two adjacent hollow rings c are connected to one another by channels d which run in the longitudinal direction of the tubes and are arranged diametrically offset and which are produced by locally pushing back the shafts. The steam flowing into the first hollow ring c at I enters the second hollow ring c through the channel d attached to the lower part of this hollow ring, flows out of this through the further channel d into the third hollow ring and, after flowing through the following hollow rings, flows through ( read outflow pipe II to the point of use.

The - '# bb. 3 and 4 illustrate a -Nbänderung of the subject - represents the invention in which instead of the inner corrugated tube, a smooth tube is inserted into the outer corrugated tube. Again, depending zwei.benachbarte hollow rings e through f diametrically offset ailgeordnete channels communicated with each other, so (let the passes 1 at flow & Steam the individual hollow rings must pass through in succession, überbitzt until it at 11 to the point of use.

Figure 5 illustrates a further variation on the subject matter of the invention. which corresponds to the design shown in Figs. 1 and 2, with the difference that the two nested corrugated pipes are separated from one another by a smooth pipe between them f connected to each other. in addition, the last hollow ring of the inner corrugated tube is surrounding hollow ring of the outer corrugated tube connected to it by a Öffnungg. the incoming at I steam in order, the individual hollow rings traverses the inner corrugated tube, passes from the last hollow ring of this tube by the Bore in the surrounding hollow ring of the outer tube, flows through the individual hollow rings of this tube one after the other and arrives at II at the point of use.

If necessary, the steam can take the opposite path, flowing in at II and out at 1.

Fig. 6 - shows an overbitter in which the outer corrugated pipe is used at the same time as the flame pipe of a steam boiler.

The advantages -of new 'Cberhitzers loading its design are in great simplicity, the low costs of production and in the quick installation.
