Description
Anwärmvorrichtung für Kesseltrommeln mit Eitileitung von Dampf in das Kesselwasser. Beim Anheizen von Steilrohrkesseln entstehen durch ungleiche Erwärmung in der Untertrommel Schwierigkeiten, die mit zunehmender Länge der Trommeln ganz erheblich wachsen und schwere Schäden verursachen können. Man hat beim Anheizen Dampf aus der Hauptdampfleitung iii die Untertrommel geblasen, welcher das Wasser in der Untertrommel in-Bewegung bringt und dadurch für eine gleichmäßige Erwärmung sorgt. Das bringt aber die große Gefahr mit sich, daß nach Erreichen des Betriebsdruckes Flüssigkeit aus der Untertrommel in die Dampfleitung gelangt, wenn die Ventile der Anwärmeleitung nicht rechtzeitig geschlossen werden oder undicht sind.Heating device for boiler drums with an inlet of steam in the boiler water. When heating up steep tube boilers, uneven heating occurs Difficulties in the lower drum, which increase with the length of the drums grow significantly and cause severe damage. One has when heating up Steam from the main steam line iii is blown down the lower drum, which is the water in motion in the lower drum and thus for even heating cares. But this brings with it the great risk that after reaching the operating pressure Liquid from the lower drum enters the steam line when the valves of the The heating line cannot be closed in time or is leaking.
Diese Gefahr sicher zu verhüten, ist der Zweck der vorliegenden Erfindung. Sie besteht darin, daß das Anwärmerohr durch den Kessel geführt und dort oberhalb des höchsten Flüssigkeitsstandes in einer den Rücktritt von Flüssigkeit ausschließenden Weise unterbrochen ist.It is the purpose of the present invention to safely prevent this danger. It consists in the heating pipe being passed through the boiler and above it the highest liquid level in a liquid that excludes the withdrawal of liquid Way is interrupted.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Abb. i und:2 sind Quer-und Längsschnitt eines mit der Erfindung ausgerüsteten Kesselteils. Abb. 3 zeigt die Unterbrechung des Anwärmerohres in größerern Maßstabe.The drawing shows an embodiment of the invention. Fig. I and: 2 are transverse and longitudinal sections of a boiler part equipped with the invention. Fig. 3 shows the interruption of the heating pipe on a larger scale.
Das von der Hauptdampfleitung kommende Anwärmerohr i ist durch eine Obertrommel 2 des Kessels in senkrechter Richtung hindurchgeführt, bei 3 oberhalb des höchsten Flüssigkeitsstandes unterbrochen und dann in Gestalt des Rohres 4 in die Untertrommel 7 geführt. Innerhalb der Untertrommel hat das Rohr einige Austrittsöffnungen. Der daraus austretende Dampf bringt das Kesselwasser in Bewegung und sorgt dadurch für gleichmäßige Erwärmung der Untertrommel. Die Unterbrechungsstelle 3 ist so ausgeführt (Abb. 3), daß das Anwärmerohr i in eine Art Düse 5 endet, die über einer trichterförmigen Erweiterung 6 der oberen Öffnung des Rohres 4 steht.The heating pipe i coming from the main steam line is passed through an upper drum 2 of the boiler in the vertical direction, interrupted at 3 above the highest liquid level and then guided into the lower drum 7 in the form of the pipe 4. The pipe has a few outlet openings inside the lower drum. The resulting steam sets the boiler water in motion and thus ensures that the lower drum is heated evenly. The interruption point 3 is designed (Fig. 3) in such a way that the heating pipe i ends in a type of nozzle 5 which stands over a funnel-shaped widening 6 of the upper opening of the pipe 4.
Während des Anheizens drückt der austretende Dampf strahl die Flüssigkeitssäule im Rohr 4 vermöge der in der DÜse 5 erlangten Geschwindigkeit vor sich her, so daß er noch mit Überdruck in die Untertrommel austritt und in. der gewünschten Weise wirkt.During the heating up, the emerging steam jet pushes the column of liquid in the pipe 4 by virtue of the speed obtained in the nozzle 5 in front of it, so that it still exits the lower drum with overpressure and acts in the desired manner.
Ist im Kessel der Betriebsdruck erreicht, so hört der Durchfluß von Dampf in der Richtung von der Hauptdampfleitung nach der Obertrommel 2 in der Anwärmeleitung i auf. Das Rohr 4 füllt sich mit Wasser aus der Untertrommel 7. Dieses Wasser kann gegebenenfalls aus dem Trichter 6 heraussprudeln, aber nicht in das Rohr i eintreten. Durch dieses kann höchstens Sattdampf in geringer Menge in die Hauptleitung gelangen.Once the operating pressure has been reached in the boiler, the flow of steam in the direction from the main steam line to the upper drum 2 in the heating line i stops. The pipe 4 fills with water from the lower drum 7. This water can optionally gush out of the funnel 6 , but not enter the pipe i. Only a small amount of saturated steam can reach the main line through this.
Die Unterbrechung der Leitung an der z# Stelle 3 kann in sehr verschiedener Art ausgeführt werden, beispielsweise auch durch eine injektorartige Einrichtung.The interruption of the line at the z # point 3 can be carried out in very different ways, for example also by an injector-like device.
