Abstract

The intermittently acting cleaning arrangement for boiler heating surface acts on the flame side surfaces. These surfaces are cleaned without interrupting boiler operations and disadvantages associated with soot or water blowers are eliminated. The heating surfaces to be cleaned is set into short vibrating movements initiated from outside the furnace. One or more vibration generators (2) can be actuated hydraulically, pneumatically or mechanically. The oscillation sequence and the impact force of each vibration generator for a given heating surface is controlled. The vibration generator is combined with a hammering cylinder (3) and it is connected by a holder directly with the boiler frame (4).

Die Erfindung betrifft ein Verfahren zur intermittierenden Reinigung der der Feuerung zugewandten Heizfläche eines Dampferzeugers.The invention relates to a method for the intermittent cleaning of the furnace facing heating surface of a steam generator.

Die bekannten Verfahren zur Reinigung der Heizflächen von Dampferzeugern od.dgl. sehen vor, daß diese Heizflächen von innen, d.h. von der der Feuerung zugewandten Seite gereinigt werden. Dies erfolgt über Ruß- und/oder Wasserbläser, die von außerhalb des Feuerraumes durch entsprechende Öffnungen in den Feuerraum eingefahren werden und das Reinigungsmedium auf die zu reinigenden Fläche aufspritzen, bzw. aufsprühen. Nachteilig bei diesen Vorrichtungen ist, daß der Heizfläche schockartig Temperaturechwankungen vorgesetzt werden, die zwangsläufig erforderlich sind, um die Anbackungen, hervorgerufen durch aggressive Medien, von der Heizfläche zu losen. Ein weiterer Nachteil ist darin zu sehen, daß der Feuerung durch die Reinigungsvorrichtung zusätzliche Luft- oder Wassermengen in Form von Dampf in bestimmten Abständen zugeführt werden, die einen optimalen Feuerungsablauf nicht gewährleisten. Unter Umständen muß die gesamte Anlage bei der Reinigung stillgelegt oder mit verminderter Feuerungsleistung gefahren werden.The known methods for cleaning the heating surfaces of steam generators or the like. provide for that these heating surfaces are cleaned from the inside, i.e. from the side facing the furnace will. This is done using soot and / or water blowers that come through from outside the combustion chamber Appropriate openings are made in the furnace and the cleaning medium on Spray or spray on the surface to be cleaned. The disadvantage of these devices is that the heating surface are exposed to sudden temperature fluctuations are inevitably necessary to the caking, caused by aggressive Media to be loosened from the heating surface. Another disadvantage is that the Firing by the cleaning device additional amounts of air or water in the form of Steam is supplied at certain intervals, which does not ensure an optimal firing sequence guarantee. Under certain circumstances, the entire system must be shut down or with the cleaning reduced combustion output.

Die Aufgabe der vorliegenden Erfindung liegt darin, ein Verfahren zur Reinigung der Heizflächen von Dampferzeugern, Wärmetauschern od.dgl., zu schaffen, das die Nachteile der bekannten Verfahren nicht aufweist, den Betriebeablauf der Gesamtanlage nicht beein-The object of the present invention is to provide a method for cleaning the heating surfaces of steam generators and heat exchangers or the like. To create that does not have the disadvantages of the known methods, does not affect the operational sequence of the entire system.

809837/0183809837/0183

flußt und individuell der Reinigung jedes einzelnen Heizflächenbereiches angepaßt werden kann.flows and can be individually adapted to the cleaning of each individual heating surface area.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die zu reinigende Heizfläche von außerhalb des Feuerraumes in kurze schwingende Bewegungen versetzt wird. Hierzu werden erfindungsgemäß eine oder mehrere an sich bekannter Schwindungserzeuger verwandt, die hydraulisch oder pneumatisch oder mechanisch betätigbar sind.This object is achieved according to the invention in that the heating surface to be cleaned by is set in short oscillating movements outside the combustion chamber. To do this will be according to the invention, one or more known shrinkage generators are used, which are hydraulic or pneumatic or mechanical are operable.

Damit jede einzelne Heizfläche und hierbei besonders jeder einzelne Heizflächenbereich individuell reinigbar ist, wird weiterhin erfindungsgemäß vorgeschlagen, daß die Schwingungsfolge und/oder die Schlagkraft eines jeden Schwingungserzeugers steuerbar sind.In order that each individual heating surface and, in particular, each individual heating surface area can be cleaned individually, it is further proposed according to the invention that the vibration sequence and / or the impact force of each vibration generator can be controlled.

Die Anordnung der als Klopfzylinder ausgebildeten Schwingungserzeuger im Gerüst des Dampferzeugers kann erfindungsgemäß direkt oder über stroßabsorbierende Elemente erfolgen.The arrangement of the vibration generators, designed as knocking cylinders, in the framework of the According to the invention, steam generator can be carried out directly or via stroßabsorbing elements.

Der entscheidende Vorteil der vorliegenden Erfindung besteht darin, daß eine Reinigung der Heizflächen während des Betriebes jederzeit möglich ist ohne Beeinflussung des Betriebsablauf es und ohne, daß die Reinigungsvorrichtung der direkten Heiseinstrahlung und/oder den aggressiven Medien des Feuerraumes ausgesetzt ist.The key advantage of the present invention is that a cleaning the heating surfaces is possible at any time during operation without influencing the operating sequence and without the cleaning device from direct heat radiation and / or is exposed to the aggressive media of the combustion chamber.

Weiterhin von Vorteil ist die individuelle Möglichkeit der Schwingungserzeugung je nach Erfordernis durch Veränderung der Schlagzahl bzw. Schlagkraft eines jeden Schwingunserzeugers.Another advantage is the individual possibility of generating vibrations depending on the Required by changing the number of blows or the force of each vibration generator.

Ein weiterer Vorteil besteht darin, daß der erfindungsgemäße Schwingungserzeuger geringfügiger Wartung bedarf und somit jederzeit einsatzbereit ist ohne Beeinflussung des Betriebsablaufes der Gesamtanlage.Another advantage is that the vibration generator according to the invention requires minor maintenance and thus at all times is ready for use without influencing the operational sequence of the entire system.

Zwei Ausführungsbeispiele sind in der Zeichnung dargestellt .und werden im folgenden näher beschrieben. Es zeigen:Two exemplary embodiments are shown in the drawing and are described in more detail below. Show it:
