Description

Verfahren zur Entfernung von Ruß bei Taschenlufterbitzern Die Erlindung bezieht sich auf ein Verfahren zur Entfernung von Ruß bei Taschen,-lufterhitzern. Sie-- besteht darin, daß Druck-und Temperaturänderungen der Erhitzexplatten in aufeinandeTfolgenden S.tößen erfolgen, welche durch plötzliche Änderung der durchströmenden Luft- oder Heizgasmengen erzielt werden.Procedure for removing soot from pocket airbusters The invention relates to a method for removing soot from pocket air heaters. It consists in the pressure and temperature changes of the heating plates in successive S. shocks take place, which by sudden change in the air or flow through Heating gas quantities can be achieved.

Bei den bekannten Tas,chen:lufterhitzern. leidet die Wärmeübertragung unter dem Ansetzen von Ruß und Flugasche, die leicht !eine feste Kruste bilden kÖnnen ' wodurch der Wärmedurchgang erheblich herabgesetzt wird. Die übliche mechanische Reinigung und die Entfernung des Rußes durch Abblasen mittels Dampfes o. dgl. ist zeitraubend und kostspielig. Ferner ist bekannt -, daß in Spannung befindliche Bleche mehr oder weniger stark-e 13,-ulen werfen und ein sehr kleiner Impuls genügt -, damit mit erheblicher Gewalt die Beule nach der anderen Seite springt. Schließlich sind Reinigungsvorrichtungen bekannt, die durch mechanisches Trommeln elastische Bewegungen der Platten bewirken.With the well-known bags: air heaters. suffers the heat transfer under the attaching of soot and fly ash, which easily! a solid crust may form 'is considerably reduced whereby the heat transfer. The usual mechanical cleaning and the removal of the soot by blowing off with steam or the like is time-consuming and costly. It is also known - that metal sheets that are under tension throw more or less strong owls and a very small impulse is sufficient - so that the dent jumps to the other side with considerable force. Finally, cleaning devices are known which, by means of mechanical drumming, bring about elastic movements of the plates.

Erfindungsgemäß sollen diese Nachteile dadurch beseitigt werden, daß durch stoßweises Zuführen der Luft o,der stoßweises Verstärken des Luftstromes die Impulse für den bekannten Vorgang des Durchbeulens der Bleche erzeugt werden. Dieses stoßweisc#Verstärken oder Zuführen des Luftstromes kann dauernd oder nur zeitweise -, z. B. durch Be%vegen einer Verschluß- oder Dr-oss,elklappe, hervorgerufen werden. Durch. die Formänderungen oder das Durchfedern der durch innere Spannungen im Blech vorhandenen Beulen bricht die Kruste aus Ruß und Flugasche ein und blättert oder springt ab. Man kann die Zahl der Stöße etwa der Eigenschwingungszahl entsprechend einrichten, um durch Resonanz eine Verstärkung zu erzielen. Es ist weiterhin mögüch, die #elastischen Forrnänderungen der Platten durch teilweise Temperaturänderungen zu erzeugen oder die Wirkungen der stoßweisün Luft.-uführung durch diese Temperaturschwankungen zu erhöhen. Die Erzeugung der Formänd,erungen kann dauernd oder zeitweilig in kürzeren oder län-Cleren Zeitabständen erfolgen.According to the invention, these disadvantages are to be eliminated in that by intermittently supplying the air o, the intermittently increasing the air flow Pulses are generated for the known process of buckling the sheet metal. This intermittent c # Increasing or supplying the air flow can be permanent or only intermittent -, e.g. B. caused by Be% vegen a closure or dr-oss, elklappe. By. the changes in shape or the spring deflection caused by internal stresses in the sheet metal Existing bumps, the crust of soot and fly ash breaks in and flakes or jumps off. The number of shocks can roughly correspond to the natural frequency set up to gain amplification through resonance. It is still possible the elastic changes in shape of the plates due to partial temperature changes to produce or the effects of the intermittent air supply through these temperature fluctuations to increase. The creation of the shape changes can be permanent or temporary in shorter periods or longer intervals.
