Description
Ekonomiser, bei dem ein gußeiserner und ein schmiedeeiserner Vorwärmer so hüitereinärider @ geschaltet sind, daß die Abgase im Gegenstrom zum Speisewasser zuerst den schmiedeeisernen Vorwärmer bestreichen.-Die Erfindung bezieht sich auf einen Ekonorniser, bei welchem ein gußeiserner und ein schmiedeeiserner Vorwärmer so hintereinander geschaltet sind, daß die Abgase im: Gegenstrom zum Speisewasser zuerst den schmiedeeisernen Vorwärmer bestreichen. Die bisherige Anordnung eines gußeisernen und eines schmiedeeisernen Vorwärmers zeigte den übelstand der Verengung der Eintrittsquerschnitte bei der schmiedeeisernen Röhrengruppe und die Anordnung dieser Röhrengruppe in Kanälen.Economizer, in which a cast iron and a wrought iron preheater are switched in such a way that the exhaust gases flow in countercurrent to the feed water first coat the wrought iron preheater.-The invention relates to an Ekonorniser with a cast-iron and a wrought-iron preheater are connected in series in such a way that the flue gases are in: countercurrent to the feed water first coat the wrought iron preheater. The previous arrangement of a cast iron and a wrought iron preheater showed the nuisance of the constriction the inlet cross-sections of the wrought-iron tube group and the arrangement this group of tubes in channels.
Die Erfindung besteht darin, daß die schmiedeeiserne Rohrgruppe, die in den Vorraum des Ekonomisers hineinragt, aus Rohren verschiedener Länge besteht, derart, daß ihre Rohrenden auf einer schrägen Linie liegen, so daß die Rauchgase günstig ausgenutzt werden, indem sie gleichmäßig in die Rohrgruppe. eingeführt werden, was bei den bisherigen. Rohrgruppen aus gleich langen Rohren nicht der Fall war. Es findet daher keine Verengung des Eintrittsquerschnittes statt, und ist die fVassenerwärmung eine weit vorteilhaftere, daher höhere als bisher.The invention consists in that the wrought iron pipe group that protrudes into the anteroom of the economizer, consists of pipes of different lengths, such that their pipe ends lie on an inclined line, so that the smoke gases can be used favorably by placing them evenly in the tube group. to be introduced what with the previous. Pipe groups of pipes of equal length was not the case. There is therefore no narrowing of the inlet cross-section and there is a rise in the water level a far more advantageous, and therefore higher, than before.
Auf der Zeichnung ist die Erfindung beispielsweise dargestellt. Der Ekonomiser a besteht aus der bekannten Rohrgruppe b aus Gußeisen und der aus Schmiedeeisen hergestellten Rohrgruppe d, deren Enden verschieden lang in die Heizkammer c hineinragen, derart, daß die Rohre in einer Schrägrichtung, wie aus der Zeichnung ersichtlich, von links oben nach rechts unten verlaufen. Diese Schrägrichtung richtet sich danach, ob der Gaseintritt von oben oder von unten erfolgt. Die Schrägrichtung ist daher der jeweiligen Eintritts- und Austrittsöffnung angepäßt. Von der schmiedeeisernen Rohrgruppe d führt ein Rohre zum Kessel oder nach einer sonstigen Verwendungsstelle.The invention is shown in the drawing, for example. The economizer a consists of the known pipe group b made of cast iron and the pipe group d made of wrought iron, the ends of which protrude into the heating chamber c of different lengths so that the pipes in an oblique direction, as can be seen from the drawing, from top left to bottom right get lost. This oblique direction depends on whether the gas enters from above or below. The oblique direction is therefore adapted to the respective inlet and outlet openings. From the wrought-iron pipe group d, a pipe e leads to the boiler or to another point of use.
