Patentirt im Deutschen Reiche vom 21. Juni 1893 ab.Patented in the German Empire on June 21, 1893.

Der neue Vorwärmer ist in Fig. 1 im Längsschnitt gezeichnet, während Fig. 2 einen Theil in der Ansicht und Fig. 3 eine Abänderung des Apparates für einen besonderen Zweck im Längsschnitt zeigen.The new preheater is shown in Fig. 1 in longitudinal section, while Fig. 2 is a part in the view and Fig. 3 shows a modification of the apparatus for a special purpose in Show longitudinal section.

Der Apparat besteht aus drei Haupttheilen, dem Aufsentopf A, dem Innenrohr B und dem zwischen beiden befindlichen Mantel C.. Bei der Anordnung nach Fig. 1 sind diese drei Theile auf einer gemeinschaftlichen Bodenplatte D montirt, welche ihrerseits auf einer erhöhten Unterlage, sei es, wie gezeichnet, ein gufseiserner Ring E, sei es Mauerwerk, seien es Holzklötze, seien es schmiedeiserne Füfse oder eine Art Dreifufs, ruht. Die Theile B und C sind oben durch einen Ring F abdichtend mit einander verbunden. Ueberhaupt sind alle Flächen, wo sich ABCD und F einander berühren, gut abgedreht und dicht in einander gepafst.The apparatus consists of three main parts, the supervisor pot A, the inner tube B and the casing C located between the two .. In the arrangement of Fig. 1 these three parts are montirt on a common bottom plate D, which in turn on a raised pad, be it As drawn, a cast iron ring E, be it masonry, be it wooden blocks, be it wrought iron feet or a kind of tripod, is resting. The parts B and C are sealingly connected to one another at the top by a ring F. In general, all surfaces where ABCD and F touch each other are well turned and fit tightly into each other.

Das Innenrohr, in Fig. 2 in Ansicht gezeichnet, ist auf seiner Aufsenfläche mit zwei zwischen einander herlaufenden Schraubengewinden α und (J₁ versehen,, welche oben unterhalb des Endflantsches b diametral einander gegenüber endigen, so dafs die zwischen beiden Gewinden gebildeten spiralförmigen Kanäle Cc₁ oben durch einen Ringkanal d mit einander in Verbindung stehen. Die unteren Enden der Kanäle c C₁ sind diametral einander gegenüber senkrecht abgeführt und münden durch die Platte D hindurch in dort angesetzte Rohrleitungen. Der Mantel C legt sich dichtend über die Gewindegänge Ua₁. Im Innern des Apparates sind somit zwei von einander getrennte Räume gebildet, nämlich zwischen Platte .D, Rohr B, Mantel C und Ring F der zwei zwischen einander herlaufende, jedoch oben mit einander verbundene, schraubenförmig gewundene Kanäle bildende Raum I und zwischen Platte D und Rohr B ein cylindrischer Raum II, der durch den zwischen Ring F und dem Boden des Topfes A bleibenden freien Raum III mit dem äufseren, zwischen Topf A und Mantel C gebildeten ringförmigen Raum IV in Verbindung steht. Es kann nun nach Belieben durch Raum I Wasser oder Dampf geleitet werden, während dann durch die anderen Räume entsprechend Dampf oder Wasser geht.The inner tube, drawn in view in Fig. 2, is provided on its outer surface with two screw threads α and (J ₁ running between each other, which end diametrically opposite one another at the top below the end flange b , so that the spiral-shaped channels Cc formed between the two threads ₁ above d communicating with each other in connection through an annular channel. the lower ends of the channels c C ₁ diametrically opposite one another perpendicular discharged and discharge by the disk D passes in scheduled there pipes. the mantle C lays sealingly over the threads Ua _1. In the interior of the apparatus, two separate spaces are thus formed, namely between plate .D, tube B, jacket C and ring F of the two between each other, but above interconnected, helically wound channels forming space I and between plate D and Tube B is a cylindrical space II, which is formed by the free space I remaining between ring F and the bottom of pot A II is in communication with the outer annular space IV formed between the pot A and the jacket C. Water or steam can now be passed through room I at will, while steam or water then passes through the other rooms accordingly.

Bei Fig. 1 ist angenommen, dafs das Wasser durch Raum I geht und durch den in dem übrigen Raum circulirenden Dampf angewärmt wird. Das kalte Wasser tritt durch die Leitung in den spiralförmigen Kanal, geht in demselben in die Höhe, oben durch den Ringkanal d und dann in dem spiralförmigen Kanal C₁ wieder abwärts und tritt durch die Leitung e_x heifs wieder aus. Der Dampf tritt durch einen Stutzen/ in der Mitte der PlatteD in den Raum II ein, geht darin in die Höhe, durch den Raum III in den Raum IV und in diesem abwärts, bis er bei g seinen Austritt findet.In Fig. 1 it is assumed that the water passes through space I and is warmed by the steam circulating in the rest of the space. The cold water enters the spiral channel through the pipe, rises in the same, up through the ring channel d and then down again in the spiral channel C ₁ and exits again through the pipe e _x hot. The steam enters space II through a nozzle / in the middle of plate D, rises in it, through space III into space IV and downwards until it exits at g.

Zur Ableitung des etwa im Raum II gebildeten Dampfwassers dient ein im Boden D angebrachter Hahn k. Der Boden D kann vertieft oder gekümpelt werden und dann k an der tiefsten Stelle seinen Platz erhalten. Auch kann man im Raum II Vorrichtungen irgend welcher Art anbringen, an denen sich der Dampf stöfst, um das Dampfwasser schneller abzugeben. Diese Vorrichtungen können auch A tap k mounted in floor D serves to drain off the steam water formed in room II. The bottom D can be deepened or curved and then k can get its place at the deepest point. You can also attach devices of any kind in room II, where the steam collides in order to release the steam water more quickly. These devices can also

be of such a nature that they press the steam more against the wall B or allow it to rise in a spiral or wave shape.

Fig. 3 shows the usability of the apparatus with slight modification for heating such liquids by means of exhaust steam, which do not always flow through, but are to be heated in certain amounts for a longer period of time. The sugar juice in sugar factories is used as an example. The latter foams very strongly, so the vessel in question must be open at the top and not completely filled and have a protective edge to prevent it from foaming over. In Fig. 3 this is achieved in that the apparatus shown in Fig. 1 is placed upside down, ie on the bottom of the pot A , the plate D is omitted and the jacket of A has been provided with the edge ring H , while the As earlier, interconnected inner parts BC and F, now no longer supported by plate D , are supported on studs, feet or support ribs and, as shown, are kept floating in A so that connecting space III between spaces II and IV is not disappears. -B and C can be tightly connected to each other at the now upper end by a ring K , or the connection can be done directly both above and below by flanging /, as shown in the right half of FIG. 4.

In the modification shown in FIG. 3, the steam entering at e and exiting at B ₁ passes through space I, while the remaining spaces of the apparatus are filled with the liquid (sugar juice) that is introduced at the top and finally drained through a tap τη at the bottom . The steam water formed in space I is collected in annular space d and from here diverted laterally through the jacket of A.

The main advantage of the new preheater is the double spiral, which is a long one Path of water and steam in two opposite directions and thus most complete Utilization of the steam heat, as well as uniform distribution of the heat in all layers of water, by either the descending hotter layers of water between the ascending colder or the descending colder layers of vapor between the ascending warmer ones, and vice versa, go through.

According to the inventor, practical tests have shown that when using the new apparatus, the well water preheated with the exhaust steam of a steam engine almost boiling off.

Godfather ν τ claim:

A preheater, characterized by the arrangement of a double thread α a _u sitting on the outer surface of a pipe wall B , over which a jacket C is slipped in a sealing manner in such a way that two coiled channels c C ₁ running between each other are formed, which are formed at one end by an annular channel d are connected to each other, but form separate mouths at the other end.
