Description
Es ist eine bekannte Erscheinung, daß sich Feuerbuchskessel mit wenig oder gar nicht gewölbten Stehkessel- und Feuerbuchsseitenwänden und im Verhältnis zur Länge der Feuerbuchse schmalem Bodenring unter der Wirkung durch den inneren t berdruck nach Art einer Bourdonröhre im Bereich des Bodenringes mit der Zeit nach außen aufbiegen. Diese Rufbiegung ist, von den Stehkesselecken beginnend, auf Längsmitte am größten und führt zu unerwünschten und unkontrollierbaren Beanspruchungen der Wände und deren gegenseitigen Verankerungen mit entsprechenden Erhaltungsaufwendungen. Es ist naheliegend und bekannt, die Verformung des Bodenringes nach außen durch Einbau eines Querankers zwischen den beiden Stelikesselseitenwänden im Bereich des Bodenringes abzufangen. Das hat aber den Nachteil, daß solche Queranker den Raum unter dem Rost verbauen, der Hitzeeinwirkung beim Ausschlacken und von der Asche und Schlacke im Aschkasten her ausgesetzt sind und schnell verrotten.It is a well-known phenomenon that firebook kettles with little or not at all arched standing boiler and fire book side walls and in proportion to the length of the fire box narrow bottom ring under the effect of the inner one t overpressure like a Bourdon tube in the area of the base ring with time bend open on the outside. This call bend is, starting from the corner of the standing boiler, on the longitudinal center greatest and leads to undesirable and uncontrollable stresses on the Walls and their mutual anchoring with corresponding maintenance expenses. It is obvious and known that the bottom ring is deformed outwards Installation of a transverse anchor between the two side walls of the Stelikessel in the area of the Intercept the ground ring. But this has the disadvantage that such transverse anchors the space Install under the grate, the effects of heat during slagging and from the ashes and slag in the ashtray are exposed and rot quickly.
Diese Nachteile vermeidet die Erfindung dadurch, daß eine Längssteife den Bodenring mit drei oder mehr Klammern umfaßt. Sie ist in der ,Zeichnung in Abb. i im Schnitt A-B und in der Abb. z in Draufsicht dargestellt. Der Bodenring i liegt zwischen Feuerbuchswand 2 und Stehkesselwand 3 eines Feuerbuchskessels. Mit Klammern 4, 5, 6 am Bodenring i verhindert eine Steife 7 jede seitliche Verformung. Zur Verteilung der Stützkräfte legt sich die Steife 7 mit Ansätzen 8, sofern Nietköpfe überbrückt werden müssen, oder auf die ganze Länge gegen den Bodenring. Die Steife 7 liegt außerhalb des Aschkastens und ist der Hitzeeinwirkung entzogen. Sie kann in ihrer Wirkung leicht überwacht werden. Bei ihr werden die Stützkräfte im Gegensatz zum einzelnen Queranker auf die ganze Länge gleichmäßig verteilt.The invention avoids these disadvantages in that a longitudinal stiffness includes the bottom ring with three or more brackets. It is shown in the drawing in Fig. i in section A-B and in Fig. z in plan view. The bottom ring i lies between fire box wall 2 and standing boiler wall 3 of a fire box boiler. With brackets 4, 5, 6 on the bottom ring i, a stiffener 7 prevents any lateral deformation. For distribution of the supporting forces, the stiffener 7 with lugs 8, provided that rivet heads are bridged must be, or over the entire length against the bottom ring. The stiffener 7 lies outside the ashtray and is not exposed to heat. She can in her Effect can be easily monitored. With her, the supporting forces are in contrast to individual cross anchors evenly distributed over the entire length.
