Description
Die Erfindung betrifft eine Kesselaufhängung, bei der der Kessel über mehrere Federaufhängungen an einer Deckenträgerkonstruktion aufgehängt ist. The invention relates to a boiler suspension, in which the boiler is suspended from a ceiling support structure via several spring suspensions.
Es ist bekannt, große Kessel an Federn aufzuhängen, um unter anderem die sich bei einer Ausdehnung des Kessels gegenüber der Stahlgerüstdecke ergebenen Längenänderungen der Anker zu ermöglichen (vgl. z. B. DE-PS 4 09 849). Die Federn sollen ferner bei jedem Lastfall eine gleichmäßige Lastverteilung auf alle Anker bewirken. Dies trifft bei der bisherigen Bauweise jedoch nur zu, wenn Kesselgerüstdecke und Kesselkörper eine große Steifigkeit besitzen. It is known to suspend large kettles on springs in order, among other things, to enable the changes in length of the anchors resulting from an expansion of the kettle with respect to the steel scaffolding ceiling (cf., for example, DE-PS 4 09 849). The springs should also bring about an even load distribution on all anchors in each load case. In the previous construction, however, this only applies if the boiler frame ceiling and boiler body have a high degree of rigidity.
Deshalb bestand bisher die Forderung, daß die Deckenträger des Kesselgerüstes so steif wie möglich dimensioniert sein sollten, und es wurde jedem Anker ein Federpaket mit der gleichen Anzahl von Federn, z. B. Tellerfedern, zugeordnet. Therefore, there was previously the requirement that the ceiling beams of the boiler frame should be dimensioned as stiff as possible, and each armature was a spring package with the same number of springs, for. B. disc springs assigned.
Diese bekannten Konstruktionen haben jedoch noch Folgende Nachteile: However, these known constructions still have the following disadvantages:
Unendlich steife Deckenträger sind nicht realisierbar. Infinitely rigid ceiling beams are not feasible.
Die auftretende Verformung bewirkt, daß nicht wie gewünscht alle Anker bzw. Federn die gleiche Last bekommen. Dieses kann man für einen Lastfall durch aufwendiges Nachstellen der Federn ausgleichen, jedoch nutzt das wenig, weil bei jeder Laständerung (z. B. fCesselverschmutzung, Trichterasche) der Fehler infolge neuer Trägerverformung wieder auftritt.The deformation that occurs has the effect that not all anchors or springs have the same load as desired receive. This can be compensated for for a load case by laborious adjustment of the springs, However, this is of little use, because every time the load changes (e.g. boiler contamination, hopper ash) the error occurs occurs again as a result of new beam deformation.
Ferner sind die Deckenträger bei den bekannten Konstruktionen wegen der BemessungsgrundlageFurthermore, the ceiling beams are in the known constructions because of the assessment basis
in »kleinste Durchbiegung« überdimensioniert.Overdimensioned in the »smallest deflection«.
Diese Nachteile werden bei einer Kesselaufhängung der eingangs beschriebenen Art dadurch vermieden, daß die Federkonstanten der einzelnen Federaufhängungen so abgestuft sind, daß an jedem AufhängepunktThese disadvantages are avoided in a boiler suspension of the type described above, that the spring constants of the individual spring suspensions are graduated so that at each suspension point
is die Summe der Federwege aus der Federaufhängung und der Durchbiegung der Deckenträger mindestens nahezu konstant ist.is the sum of the spring travel from the spring suspension and the deflection of the ceiling beams is at least almost constant.
Bei einer bevorzugten Ausführungsform der Erfindung sind die Federaufhängungen als Federpakete aus
Tellerfedern ausgebildet, und die Anzahl der Tellerfedern in den Federaufhängungen ist in der Mitte des
Deckenträgers am geringsten und nimmt zu den Auflagern des Deckenträgers hin zu.
Die mit der Erfindung erzielbaren Vorteile bestehen darin, da3 Deckenträger mit kleinerem Trägheitsmoment,
also mit größerer Verformung, gewählt werden können. Der Verfo-mungszuwachs des Deckenträgers
wird durch Einsparung bei den Tellerfedern kompensiert. In der Praxis können 18% des Gesamtgewichtes
der Kesseldecken-Stahlkonstruktion eingespart werden. Die Anzahl der benötigten Tellerfedern reduziert
sich um bis zu 30%.In a preferred embodiment of the invention, the spring suspensions are designed as spring assemblies of disc springs, and the number of disc springs in the spring suspensions is lowest in the middle of the ceiling support and increases towards the supports of the ceiling support.
The advantages that can be achieved with the invention are that ceiling beams with a smaller moment of inertia, that is to say with greater deformation, can be selected. The increase in deformation of the ceiling beam is compensated for by saving on the disc springs. In practice, 18% of the total weight of the boiler roof steel construction can be saved. The number of disc springs required is reduced by up to 30%.
Die Erfindung wird anhand des in der Zeichnung schematisch dargestellten Ausführungsbeispiels näherThe invention is explained in more detail with reference to the exemplary embodiment shown schematically in the drawing

Hierin sind mit 1 der Deckenträger der Kesseldekkenkonstruktion und mit 2 dessen Auflager bezeichnet. Die einzelnen Federaufhängungen 3 sind mit starren Ankern 4 verbunden, welche ihrerseits am Kessel 5 befestigt sind. Die Federaufhängungen 3 sind als Federpakete aus Tellerfedern ausgebildet, die auf der Oberkante des Deckenträgers 1 gelagert sind. Die mit ihnen verbundenen Anker 4 gehen durch den Deckenträger 1.Here are the ceiling beams of the boiler ceiling construction with 1 and with 2 denotes its support. The individual spring suspensions 3 are rigid Anchors 4 connected, which in turn are attached to the boiler 5. The spring suspensions 3 are as Spring assemblies formed from disc springs which are mounted on the upper edge of the ceiling support 1. With Anchors 4 connected to them go through the ceiling beam 1.
