Abstract
Description
Die Erfindung betrifft eine Anordnung zum Abdichten des Überganges zwischen dem ersten und zweiten Zug eines mit Membranrohrwänden versehenen Dampfkessels.The invention relates to an arrangement for sealing the Transition between the first and second move one with Steam boiler provided with membrane tube walls.
Dabei weisen die Oberkanten der Sattelschrägen Flansche zur Fixierung eines waagerechten Kompensators, die Abschlüsse der Membranrohrseitenwände über an winkelförmigen Trägern befestigte Flansche zur Fixierung eines senkrechten Kompen sators sowie die Gehäusehaube des Überganges und die Ober kanten der Membranrohrseitenwände über an weiteren winkel förmigen Trägern befestigte Flansche zur Fixierung eines weiteren waagerechten Kompensators auf.The top edges of the saddle slopes have flanges Fixing a horizontal compensator, the terminations the membrane tube side walls over on angular supports attached flanges for fixing a vertical compen sators as well as the housing hood of the transition and the upper edges of the membrane tube side walls at further angles Shaped carriers attached flanges for fixing a further horizontal compensator.
Die Verbindungen zwischen den Kompensatoren erfolgt mit Übergangs-Kompensatoren (DE 44 38 819). Dabei sind die Kom pensatoren als Werkstoff-Kompensatoren ausgebildet und wei sen die entsprechenden mechanisch, thermisch und chemisch beaufschlagten Schichtmaterialien auf. Die Weichstoff- Kompensatoren sind durch Schweißen der metallischen Schicht materialien, Verkleben der Kunststoff-Schichtmaterialien und Vernähen der Gewebe-Schichtmaterialien verbunden.The connections between the expansion joints are made with Transition compensators (DE 44 38 819). The com pensators designed as material compensators and white the corresponding mechanical, thermal and chemical applied layer materials. The soft Compensators are made by welding the metallic layer materials, bonding the plastic layer materials and Sewing the fabric layer materials together.
Nachteilig daran ist, daß nicht alle multilateralen durch Ausdehnung bedingten Relativbewegungen und Schwingungen des Membranrohrsystems durch die Kompensation ausgeglichen und aufgenommen werden können.The disadvantage of this is that not all multilateral through Expansion-related relative movements and vibrations of the Membrane pipe system compensated by the compensation and can be included.
Der Erfindung liegt die Aufgabe zugrunde, die durch die Tem peraturdifferenz entstehenden multilateralen Relativbewegun gen und die damit verbundenen unterschiedlichen Ausdehnungen und Schwingungen durch eine neue Befestigung der Weichstoff- Kompensatoren und der Übergangs-Weichstoff-Kompensatoren aufzunehmen und auszugleichen.The invention is based, which by the Tem resulting multilateral relative movement conditions and the associated different expansions and vibrations through a new attachment of the soft material Compensators and the transition soft material compensators record and balance.
Dies wird dadurch erreicht, daß erfindungsgemäß die senk rechten Kompensatorflansche über quasi elastisch angeordnete Träger mit den waagerechten Kompensatorflanschen verbunden und die Übergangs-Kompensatoren an den Trägern befestigt sind.This is achieved in that the lower according to the invention right compensator flanges over quasi elastically arranged Carrier connected to the horizontal compensator flanges and the transition compensators attached to the beams are.
Anhand eines Ausführungsbeispiels soll nachstehend die Er findung näher erläutert werden. Dabei zeigt:Using an embodiment, the Er invention are explained in more detail. It shows:
Fig. 1 die Kompensatoren-Anordnung im Haubenbereich Fig. 1, the compensator arrangement in the hood area
Fig. 2 die Kompensatoren-Anordnung im Sattelbereich. Fig. 2 shows the expansion joint arrangement in the saddle area.
Die Anordnung dient zum Abdichten des Überganges zwischen dem ersten und zweiten Zug 1; 2 des mit Membranrohrwänden versehenen Dampfkessels. Dazu sind an der Gehäusehaube 5 der Haubenflansch 34 und an den Membranrohrwänden die Kompensa torflansche 18; 19 für die Befestigung der waagerechten Weichstoff-Kompensatoren 35; 36 befestigt. Die Weichstoff- Kompensatoren 35; 36 sind mittels der Nahtstellen 37; 38; 39; 40 mit dem Übergangs-Kompensator 21 verbunden. Der Über gangs-Kompensator 22 ist an spitzwinklig ausgebildeten und trapezförmig angeordneten Trägern 26; 27; 28; 29 befestigt. Der Übergangs-Kompensator 21 ist über die Nahtstelle 37 mit dem senkrechten Weichstoff-Kompensator 10 verbunden, der in den Kompensatorflanschen 11; 12 an der Unterkonstruktion 13; 14 befestigt ist. Der Weichstoff-Kompensator 10 ist über die Nahtstelle 20 mit dem Übergangs-Kompensator 22 im Sattelbe reich 3; 4 verbunden.The arrangement serves to seal the transition between the first and second train 1 ; 2 of the steam boiler with membrane tube walls. For this purpose on the housing cover 5 of the bonnet flange 34 and the membrane tube walls, the Kompensa torflansche 18; 19 for fastening the horizontal soft material expansion joints 35 ; 36 attached. The soft material compensators 35 ; 36 are by means of the seams 37 ; 38 ; 39 ; 40 connected to the transition compensator 21 . The transition compensator 22 is on acute-angled and trapezoidal arranged supports 26 ; 27 ; 28 ; 29 attached. The transition compensator 21 is connected via the interface 37 to the vertical soft material compensator 10 , which is in the compensator flanges 11 ; 12 on the substructure 13 ; 14 is attached. The soft material compensator 10 is rich over the interface 20 with the transition compensator 22 in the saddle 3 ; 4 connected.
Der Übergangskompensator 22 ist an stumpfwinklige Träger 30; 32; 32; 33 zwischen den Sattelschrägen 24; 25 befestigt und über die Nahtstelle 23 mit den waagerechten Kompensatorflan schen 15; 16 verbunden, die in den Kompensatorflanschen 6; 7; 8; 9 befestigt sind. Über dem waagerechten Kompensator 15 der Sattelbereiche 3; 4 ist ein einseitig fixierter Ver schleißschutz 17 angeordnet.The transition compensator 22 is on obtuse-angled supports 30 ; 32 ; 32 ; 33 between the saddle slopes 24 ; 25 attached and over the interface 23 with the horizontal Kompensatorflan rule 15 ; 16 connected in the compensator flanges 6 ; 7 ; 8 ; 9 are attached. Above the horizontal compensator 15 of the saddle areas 3 ; 4 , a wear protection 17 fixed on one side is arranged.
Durch die Erfindung werden folgende Vorteile erreicht:
The following advantages are achieved by the invention:
- 1. Durch den Weichstoff-Kompensator werden die Bewegungen, die in allen 3 Dimensionen auftreten, ausgeglichen.1. The movements, that occur in all 3 dimensions, balanced.
- 2. Aufgrund des Spannungsabbaus wird der Kompensator weniger beansprucht und die Lebensdauer erhöht.2. Due to the voltage reduction, the compensator becomes less stressed and the lifespan increased.
- 3. Es wird der konstruktive Aufbau vereinfacht.3. The constructive structure is simplified.
