Description
Fig,7 eine der Fig.5 entsprechende Draufsicht auf eine Umlenkscheibe mit einem durchgehenden Schlitz.7 shows a top view corresponding to FIG a deflection pulley with a continuous slot.
Mit 101 ist ein U«förmiger Träger aus beispielsweise hochtemperaturbeständigem Stahl bezeichnet. Dieser dient als Auflage für einen aus einem Rohr 7 und zwei an dessen Rohrenden angeordneten Umlenkscheiben tO und 11 bestehenden Einsatz 6, Das Ganze wird in einen Heizkessel mit Befeuerung durch einen Zerstäubungsbrenner in geringem Abstand vom Brennerende, das ist in der Regel das in der Zeichnung angedeutete Mischrohr 14, so angeordnet, daß Flammenachse und Einsatzachse wenigstens annähernd in einer Linie liegen.101 is a U «shaped carrier from, for example called high temperature resistant steel. This serves as a support for one of a tube 7 and two on whose pipe ends arranged deflection discs tO and 11 existing insert 6, the whole is in one Boiler fired by an atomizing burner at a short distance from the end of the burner, that is usually the indicated in the drawing mixing tube 14, arranged so that flame axis and Insert axis are at least approximately in one line.
Die Teile des Einsatzes 6 bestehen aus feuerfester Keramik. Dabei ist das Rohr 7, das hier aus zwei etwa kegelförmigen Rohrabschnitten 7a und Tb besteht, mit einer sich vorzugsweise Ober die gesamte Mantellänge erstreckenden Längskerbe 107 versehen, wie bei der Ausführung am Rohrabschnitt 7a und der Fig.2 ersichtlich. Durch diese Maßnahme wird eine Sollbruchstelle erzeugt, die bei der auftretenden Temperaturwechselbeanspruchung einen Riß bildet. Hierdurch kann sich das Rohr bzw. der Rohrabschnitt ausdehnen und zusammenziehen, ohne daß weitere Spannungsrisse entstehen. Anstelle einer Längskerbe 107 kann auch vonThe parts of the insert 6 are made of refractory ceramic. The tube 7, which here consists of two approximately conical tube sections 7a and Tb , is provided with a longitudinal notch 107 that preferably extends over the entire length of the jacket, as can be seen in the embodiment on tube section 7a and FIG. This measure creates a predetermined breaking point which forms a crack when exposed to thermal cycling. As a result, the pipe or the pipe section can expand and contract without further stress cracks occurring. Instead of a longitudinal notch 107 can also be from
vornherein ein durchgehender Lftngssehlitz 108 vorgesehen sein. Diese Ausführungsmöglichkeit zeigt der Rohrabschnitt Tb (F i g, 3),A continuous longitudinal slot 108 may be provided from the start. This design option is shown by the pipe section Tb (Fig. 3),
Zur Verhinderung von Spannungsrissen in den Umlenkscheiben 10, Il können diese ebenfalls mit einer Kerbe 109 und gegebenenfalls einer dieser gegenüberliegenden zweiten Kerbe 110 versehen sein. Sie bildet bzw, bilden eine bei Temperaturwechselbeanspruchung wirksam werdende Sollbruchstelle. Die Kerben 109,110 sind zweckmäßig aus Herstellungsgründen radial angebracht Eine derartige Ausführung ist bei der linken Umlenkscheibe 10 und in den Fig.4, 5 und 6 vorgesehen. Auch hier entsteht beim Betrieb ein Riß 111, wie in F i g. 6 gezeigt Anstelle der Kerben 109, $ 10 kann auch von vornherein ein durchgehender Trennschlitz 112 vorgesehen sein, wie dies bei der rechten Umlenkscheibe 11 in F i g. 1 und in der F i g. 7 dargestellt istTo prevent stress cracks in the deflecting pulleys 10, II, these can also be provided with a Notch 109 and optionally a second notch 110 opposite this may be provided. She educates or, form a predetermined breaking point that becomes effective when exposed to temperature changes. The notches 109,110 are expediently attached radially for manufacturing reasons. Such a design is on the left Deflection pulley 10 and in FIGS. 4, 5 and 6 intended. Here, too, a crack 111 arises during operation, as in FIG. 6 shown in place of notches 109, $ 10 A continuous separating slot 112 can also be provided from the outset, as is the case with the right one Deflection pulley 11 in FIG. 1 and in FIG. 7 shown is
Die an den Enden 8 und 9 des RohiOs 7 bzw. der Rohrabschnitte 7a und Tb anliegenden Nocken 114,114' der Umlenkscheiben 10, 11 dienen zur Erzeugung von Durchlaßöffnungen 20, 20' zwischen der weiden Teilen. Hierdurch wird in der sich im Hauptpaten: im einzelnen beschriebenen Weise eine den Verbrennungsprozeß fördernde Rezirkulation von Flammengasen erzeugt.The cams 114, 114 'of the deflecting disks 10, 11 resting on the ends 8 and 9 of the tube 7 or the pipe sections 7a and Tb serve to create passage openings 20, 20' between the two parts. In this way, in the manner described in detail in the main patent, a recirculation of flame gases that promotes the combustion process is generated.
