Die Neuerung besteht aus der Anbringung von ' Siedetaschen in den Feuerrohren von Dampfkesseln, um die Heizfläche zu vergröfsern.The innovation consists of the attachment of 'boiling pockets' in the fire tubes of Steam boilers to enlarge the heating surface.
In der Zeichnung bedeutet Fig. 1 einen Querschnitt durch einen Dampfkessel und Fig. 2 einen Längsschnitt durch denselben.In the drawing, Fig. 1 denotes a cross section through a steam boiler and Fig. 2 is a longitudinal section through the same.
c ist der Dampfkessel mit den Feuerrohren a a. In diesen Feuerrohren α befinden sich Siedetaschen bb, welche durch die Oeffnungen ee und das Rohr d mit dem Wasserraum des Dampfkessels verbunden sind. Die Siedetaschen b bestehen demnach hauptsächlich aus einer senkrechten Falte des Feuerrohres; zur Versteifung dieser Falte und um der senkrechten Wasserströmung Eingang zu verschaffen, dient das senkrechte Rohr d. c is the steam boiler with the fire tubes a a. In these fire pipes α there are boiling pockets bb which are connected to the water space of the steam boiler through the openings ee and the pipe d. The boiling pockets b therefore mainly consist of a vertical fold of the fire pipe; the vertical pipe d serves to stiffen this fold and to provide entry for the vertical water flow.
Es giebt bereits Siedetaschen in den Feuerungsrohren von Dampfkesseln, die sich abernicht bewährt haben, da man nur daran dachte, die Heizfläche zu vergröfsern, ohne für die nöthige Festigkeit Sorge zu tragen. Die bis dahin bekannten Siedetaschen bestehen meistens aus mehr oder weniger horizontal in den Feuerrohren angebrachten, flach gedrückten Rohren, die nur mittelst seitlicher Oeffnungen mit dem Wasserraum in Verbindung stehen und die heifsen Gase über und unter sich vorüberstreichen lassen.There are already pockets of boiling point in the furnace tubes of steam boilers, but they cannot be have proven, since one only thought of enlarging the heating surface without adding to the to take care of the necessary strength. The boiling pockets known up to then mostly exist from more or less horizontally placed in the fire tubes, flattened Pipes that are only connected to the water space by means of lateral openings and let the hot gases pass over and under.
Wenn nun die neuen Siedetaschen in der Hauptsache auch nur aus flachen, horizontal mit dem Wrasserraum verbundenen Taschen bestehen, so besteht doch gegenüber den früheren der wesentliche Unterschied, dafs sie sich dicht an das Feuerrohr anlegen und daher am gröfsten Theil ihres Umfanges von dem Wasser des Kessels bespült werden, so dafs kein Ueberhitzen derselben eintreten kann.Now, if the new Siedetaschen consist mainly only from flat, horizontal connected to the W r asserraum bags, there is still over the earlier the main difference, that they be close to the fire tube invest and therefore the greater part of the circumference of the Water from the boiler must be flushed so that it cannot overheat.
Durch die senkrechte Verbindung der Tasche mittelst des Rohres d erhält dieselbe nicht allein eine bedeutende Festigkeit gegenüber den bekannten und erlaubt ein leichteres und bequemeres Vernieten mit dem Feuerrohr, sondern es entsteht dadurch auch eine senkrechte Wasserströmung in der Tasche, die es vermeidet, dafs sich die Tasche voll Dampf setzt und dadurch überhitzt werden kann.The vertical connection of the pocket by means of the tube d not only gives it a significant strength compared to the known ones and allows easier and more convenient riveting to the fire tube, but also creates a vertical flow of water in the pocket, which prevents the Bag full of steam sets and can be overheated as a result.
