Description

Vorrichtung zur Zugbeschleunigung bei Dampfkesseln mit nachgeschaltetem, abgasbeheiztem Luftvorwärmer Die Erfindung bezieht sich auf eine Vorrichtung zur Zugbeschleunigung bei Dampfkesseln mit nachgeschaltetem, abgasbeheiztem Luftvorwärmer. Zu dem Zweck ist zwischen Luftvorwärmer und Schornstein ein diffusorartiges Rohrstück eingebaut, in dessen weitester Stelle ein Ventilator vorgesehen ist.Device for accelerating the draft in steam boilers with a downstream, exhaust gas heated air preheater The invention relates to a device for Train acceleration in steam boilers with a downstream, exhaust-gas heated air preheater. For this purpose, there is a diffuser-like piece of pipe between the air preheater and the chimney built-in, in the widest point of which a fan is provided.

Der Erfindungsgegenstand ist in der Zeichnung in einer Ausführungsform schematisch dargestellt. _^ Der Luftvorwärmer i liegt hinter der Feuerung 2 bzw. hinter den Apparaten, wie z. B. Kesseln, die von dieser Feuerung geheizt werden. Der Weg der Luft und der Verbrennungsgase ist auf der Zeichnung durch Pfeile angedeutet.The subject of the invention is shown in the drawing in one embodiment shown schematically. _ ^ The air preheater i is located behind the furnace 2 or behind the apparatus, such as B. boilers that are heated by this furnace. The path of the air and the combustion gases is indicated on the drawing by arrows.

In dem am Luftvorwärmer anschließenden, nahezu kegelstumpfförmigen Diffusor 3 ist an seinem den größten Durchmesser besitzenden Ende entgegengesetzt zum Wärmeaustauscher i ein Ventilator 4 zum Absaugen * der Verbrennungsgase eingebaut. Bei ihrem Austritt aus dem Diffusor 3 gelangen die Rauchgase in eine geräumige Kammer 5, die im unteren Teil des Schornsteins 6 vorgesehen.ist. In dieser Kammer werden die Gase infolge eines über die geeignet angeordneten Scheiben 7 niedergehenden Sprühregens mit Wasserdampf gesättigt. Das Wasser wird einem im Schornstein 6 aufgehängten Wasserbehälter 8 entnommen.In the almost frustoconical one adjoining the air preheater Diffuser 3 is opposite at its largest diameter end to the heat exchanger i a fan 4 is installed to extract * the combustion gases. When they exit the diffuser 3, the flue gases enter a spacious chamber 5, which is provided in the lower part of the chimney 6. Be in this chamber the gases as a result of falling over the suitably arranged disks 7 Drizzle saturated with water vapor. The water is hung up in the chimney 6 Water tank 8 removed.
