,DESIREDUPUISiNjUPPILLE(BELGiEIi).. Vorkehrung zum Mischen von Wärme übertragenden Flüssigkeiten., DESIREDUPUISiNjUPPILLE (BELGIUM) .. Provision for mixing heat transferring liquids.
Patentirtyim Deutschen Reiche/vom 14. Mai 1878 ab.Patentirty in the German Empire / from May 14, 1878.
Bei allen Heizungsanlagen, bei welchen die durch Verbrennung erzeugte Wärme, sei es nun durch die Heizgase selbst oder durch irgend eine andere übertragende Flüssigkeit behufs Abgabe der Wärme durch Röhren geleitet werden, geht ein grofser Theil der Wärme verloren oder kommt erst an einer falschen Stelle zur Wirkung, weil der erhitzte Strom nur in seinen äufsersten Schichten mit der Röhrenwandung, die die Wärme aufnimmt, in Berührung kommt.In all heating systems in which the heat generated by combustion, be it by the heating gases themselves or by some another transferring liquid is passed through tubes to give off the heat, if a large part of the heat is lost or only takes effect in a wrong place, because the heated current only in its outermost layers with the tube wall, which absorbs the warmth comes into contact.
Dieser Uebelstand tritt um so mehr hervor, je schneller das Wärme übertragende Fluidum die Röhre durchzieht, weil dann nur die äufsersten die Röhrenwand berührenden Schichten zur Wirkung gelangen, der innere Kern dagegen infolge ,mangelnder Mischung keine Gelegenheit zur Abgabe seiner Wärme an die Röhrenwand erhält, an die umgebenden kalter gewordenen Schichten aber um so weniger Wärme abgiebt, je schneller die Bewegung, je gröfser der Zug ist, und zwar weil Gase J schlechte Wärmeleiter sind und ein geringes specifisches Gewicht haben, ,so dafs z. B. bei vertical stehenden Röhren gar kein. Wärmeaustausch zwischen den äufseren Schichten und dem inneren Kern der Gase stattfindet und ein grofser Theil der Wärme unbenutzt durch den Kamin entweicht.This inconvenience becomes more apparent, the faster the heat-transferring fluid passes through the tube, because then only the outermost layers in contact with the tube wall come into effect, while the inner core, due to insufficient mixing, has no opportunity to transfer its heat to the tube wall. but the less heat is given off to the surrounding layers, which have become colder, the faster the movement, the greater the pull, namely because gases J are poor conductors of heat and have a low specific gravity. B. with vertically standing tubes none at all. Heat exchange takes place between the outer layers and the inner core of the gases, and a large part of the heat escapes unused through the chimney.
Ein Hülfsmittel, diesen Uebelstand zu heben, also eine bessere Wärmeabgabe und Ausnutzung
durch Mischen der Wärme übertragenden Gase oder sonstigen Fluida zu erzielen und dieselben
so zu dirigiren, dafs stets neue Theile derselben mit der Heizfläche in Berührung kommen, bildet
den Gegenstand der vorliegenden Erfindung.
~ Dieses Hülfsmittel besteht in der Anordnung- > von spiralförmig gewundenen Blechstreifen, also
Schnecken, welche in die Röhre eingefügt werden, gleichviel ob sie die ganze Länge der
Röhre oder nur einzelne Stücke der Röhrenlänge einnehmen und ob dieselben in der
Röhre fest oder beweglich angeordnet sein mögen.The subject of the present invention is an aid to alleviate this disadvantage, i.e. to achieve better heat emission and utilization by mixing the heat-transferring gases or other fluids and to direct them so that new parts of them always come into contact with the heating surface.
~ This aid consists in the arrangement -> of spirally wound sheet metal strips, i.e. snails, which are inserted into the tube, regardless of whether they take up the entire length of the tube or only individual pieces of the tube length and whether they are arranged in the tube in a fixed or movable manner like.
Zum besseren Verständnifs ist auf der beiliegenden Zeichnung eine Röhre, mit einem derartigen Wärmelenker versehen, im senkrechten Längenschnitt dargestellt. Derselbe besteht, wie zu sehen, einfach aus der aus Flacheisen oder Blech gedrehten Schnecke oder Spirale S, welche in die Röhre Ji eingeschoben wird. Diese/" Spirale zwingt die durch die Röhre R ziehenden Gase oder sonstigen Fluida, einen spiralförmigen Lauf anzunehmen, wodurch die Mischung bewerkstelligt wird und stets neue Theile der Verbrennungsgase, welche noch nicht ihre Wärme abgegeben, der umgebenden Röhrenwand zugeführt werden.For a better understanding, a tube, provided with such a heat deflector, is shown in a vertical longitudinal section on the accompanying drawing. As can be seen, it consists simply of the screw or spiral S turned from flat iron or sheet metal, which is pushed into the tube Ji. This / "spiral forces the gases or other fluids that are pulling through the tube R to assume a spiral-shaped course, whereby the mixture is brought about and new parts of the combustion gases, which have not yet given off their heat, are constantly fed to the surrounding tube wall.
Die Vorrichtung hat den Vortheil, dafs sie den Querschnitt der Röhre nur um ein Minimum verengt, den Weg der Gase oder sonstigen Wärme übertragenden Fluida vergröfsert bezw. die Geschwindigkeit verlangsamt und dabei in der angegebenen Weise stets 'neue heifse Gastheile mit der Röhrenwand in Berührung bringt. Aufserdem aber hat sie noch den werthvollen Nebenzweck, zum Abreiben und Entfernen von Rufs, Flugasche, Kesselstein etc. zu dienen.The device has the advantage that it only minimizes the cross-section of the tube narrowed, the path of gases or other heat-transferring fluids enlarged respectively. the speed is slowed down and, in the same way, always new hot parts of the gas brings into contact with the tube wall. But she also has the valuable one Secondary purpose, to be used for rubbing off and removing Rufs, fly ash, scale, etc.
