Description

Durchziehmodell zur . ` g von Rippenheizkörpern lZauchgasvorwärtner bestehen heute vorwiegend aus gegossenen Rippenheizkörpern, «,-elche, zu Gruppen und Kolonnen zusammengebaut, den eigentlichen Vorwärmen bilden. Gewöhnlich sind dabei die M'asservorwärmer und die Luftvorwärmer ganz verschieden gebaut, so daß für jede Verwendungsart besondere Modelle angefertigt werden müssen. Pull-through model for. `g of finned radiators Flue gas feeders nowadays mainly consist of cast ribbed radiators, «, -moose, assembled in groups and columns, which form the actual preheating. Usually the mass preheaters and the air preheaters are built very differently, so that special models have to be made for each type of use.

Bei den zahlreichen und gewöhnlich langen, dünnen Rippen müssen die Modelle als Kamm- oder Durchziehmodelle leergestellt «-erden, welche naturgemäß teuer sind. Diese Kosten lasen sich sofort auf die Hälfte verringern" wenn man für beide Verwendungszwecke ganz gleiche lloclelle verwendet, (l. h. Modelle, die einander in den Abmessungen der äußeren Rippen und der Flansche getrau entsprechen. Der innere Einbau, der durch Kerne hergestellt wird, muß natürlich nach wie vor dem Verwendungszweck angepaßt werden. Man kann also bei dem Lufterhitz_errohr eine genügend große Anzahl von Rippen im Innern anbringen, um hier einte <leg äußeren Heizfläche entsprechende _ innere Heizfläche unterzubringen.With the numerous and usually long, thin ribs, the Models as comb or pull-through models "-ground empty", which naturally are expensive. These costs can be cut in half "if you pay for." both uses quite the same lloclelle used, (l. h. models, each other correspond in the dimensions of the outer ribs and the flanges. The inner one Installation, which is produced by cores, must, of course, still depend on the intended use be adjusted. So you can have a sufficiently large number with the Lufterhitz_errohr of ribs on the inside to create an appropriate outer heating surface _ to accommodate inner heating surface.

Ahl). z zeigt ein Luftvorwä rmerrohr im Querschnitt, Abb. 2 ein solches in Ansicht. Es ist ein flacher Körper e, welcher mit Querrippen d versehen ist und an beiden Rohrenden Anschlußflansche besitzt. Bei dem Wasservorwä rnner (4bb. ß und 4.) werden die Flansche mit abnehmbaren AbschIttl3-kappen u und U ausgerüstet. die zur Zu- und Ableitung des Betriebswassers dienen. Bei dem Luftvorwärrner bleiben die Zu- und ränge offen.Ahl). z shows a Luftvorwä rmerrohr in cross section, Fig. 2 such in view. It is a flat body e, which is provided with transverse ribs d and has connecting flanges at both pipe ends. With the water preheater (4bb and 4.) the flanges are equipped with removable section caps u and u. which serve to supply and discharge the process water. Stay with the air preheater the entrances and ranks open.

Die äußere Gestaltung ist. wie ersichtlich, bei beiden Heizkörpern vollkommen gleich. so dali auch das gleiche Durchzugstnociell für beide Rohrformen Verwendung finden kann. da auch die Rippen c bei beiden Modellen die gleichen sind.The exterior design is. as can be seen on both radiators completely the same. so there is also the same draft standard for both tube shapes Can be used. since the ribs c are the same on both models.
