Description

Die Erfindung betrifft eine Auskleidung in einem Schornstein, der ein Futtermauerwerk aufweist, bestehend aus Rohrschüssen aus faserverstärktem Kunststoff und zwischen den Rohrschüssen angeordneten Weichstoffkompensatoren, wobei zwischen dem Futtermauerwerk und den Rohrschüssen ein belüfteter Ringraum gebildet ist.The invention relates to a lining in a chimney, which has a lining masonry consisting of pipe sections made of fiber-reinforced plastic and between the pipe sections arranged soft material expansion joints, being between the lining masonry and a ventilated annular space is formed for the pipe sections is.

Die Auskleidung dient der Ertüchtigung vorhandener Schornsteine zur Ableitung von Rauchgasen aus fossilen Kraftwerken und Industriefeuerungsanlagen, die nachträglich mit Naßwäschern ausgerüstet werden. Bei der Nachrüstung eines Kraftwerkes mit einer Rauchgasentschwefelungsanlage, die mit einem Naßwäscher arbeitet, ändern sich die Betriebsdaten für den vorhandenen Schornstein. So wird die Ablufttemperatur, die bei einem Kraftwerk ohne Rauchgasentschwefelungsanlage bis 180 °C betragen kann, auf 80 bis 100 °C abgesenkt. Die drastische Temperatursenkung der Abluft führt zur Unterschreitung des Taupunkts im Schornstein, wobei aggressive Abluftbestandteile kondensieren und das Futtermauerwerk angreifen. Fällt die Rauchgasentschwefelungsanlage aus oder wird sie zeitweise außer Betrieb genommen, so kehren sich die vorgenannten Temperaturverhältnisse schlagartig um. Eine Schornsteinauskleidung zur Ertüchtigung eines vorhandenen Schornsteins für die Ableitung gewaschener Rauchgase muß folglich nicht nur einen dauerhaften Schutz des Futtermauerwerks gewährleisten, sondern auch für große betriebliche Temperaturschwankungen ausgelegt sein. Beachtliche Wärmedehnungen der Schornsteinauskleidung, die mit den betrieblichen Temperaturschwankungen verbunden sind, müssen aufgenommen werden, ohne Spannungen in das Futtermauerwerk einzuleiten. Dies stellt besondere Anforderungen an die Halterung der Schornsteinauskleidung.The lining serves to upgrade existing chimneys for the discharge of flue gases from fossil power plants and industrial combustion systems that are retrofitted with wet washers be equipped. When retrofitting a Power plant with a flue gas desulphurization plant, which a wet scrubber works, the operating data for the existing chimney. So the exhaust air temperature, in a power plant without a flue gas desulfurization system can be up to 180 ° C, lowered to 80 to 100 ° C. The drastic lowering of the temperature of the exhaust air leads to a shortfall of the dew point in the chimney, with aggressive exhaust air components condense and attack the lining masonry. If the flue gas desulphurization system fails or will if they are temporarily taken out of service, the aforementioned will be reversed Temperature conditions suddenly change. A chimney liner to upgrade an existing chimney consequently for the discharge of washed flue gases not only ensure permanent protection of the lining masonry, but also for large operational temperature fluctuations be designed. Considerable thermal expansion of the Chimney lining that with the operational temperature fluctuations connected must be included without Introduce tensions in the lining masonry. This poses special requirements for the mounting of the chimney lining.

Bei einer aus DE-A 43 25 827 bekannten Auskleidung zur Ertüchtigung eines Schornsteins mit Futtermauerwerk sind die aus glasfaserverstärktem Kunststoff (GFK) bestehenden Rohrschüsse an Konsolen aufgehängt, die als Stahlbetonringe ausgeführt sind und über Profilträger mit einem außenseitigen Stahlbetonmantel des Schornsteins verbunden sind. Die GFK-Rohrschüsse haben keine Verbindung mit dem Futtermauerwerk und können demzufolge große Wärmedehnungen ausführen, ohne daß Spannungen in das Futtermauerwerk eingeleitet werden. Die bekannte Schornsteinauskleidung hat sich in funktionsmäßiger Hinsicht bewährt. Die GFK-Rohrschüsse müssen jedoch als dickwandige, durch außenseitige Ringe verstärkte Bauteile ausgeführt werden, um die auf die Auskleidung wirkenden Druckkräfte infolge des im Schornsteinkanal wirkenden Unterdrucks aufzunehmen. Die bekannte Auskleidung hat aus statischen Gründen ein hohes Gewicht. Die Montage der Auskleidung ist aufgrund der außenliegenden Verstärkungsringe ferner verhältnismäßig aufwendig.With a lining known from DE-A 43 25 827 for retrofitting of a chimney with lining masonry are the Pipe sections made of glass fiber reinforced plastic (GRP) hung on brackets designed as reinforced concrete rings are and via profile beams with an outside Reinforced concrete jacket of the chimney are connected. The GFK pipe sections have no connection with the lining masonry and can therefore carry out large thermal expansions without that tensions are introduced into the lining masonry. The well-known chimney lining has become functional Proven. However, the GRP pipe sections must be thick-walled, Components reinforced by rings on the outside the compressive forces acting on the lining due to the negative pressure acting in the chimney duct. The known lining has for static reasons heavy weight. The assembly of the liner is due the outer reinforcement rings are also proportionate complex.

Eine aus DE-C 42 26 902 bekannte GFK-Auskleidung besteht aus Platten, die an der Innenwand eines fluiddurchströmten Raumes befestigt werden. Die Platten weisen in Plattenlängsrichtung verlaufende Stege mit an der Innenwand des auszukleidenden Raumes anschraubbarem Fußflansch auf. Die Befestigungsschrauben durchfassen Langlöcher des Fußflansches, so daß durch Wärmedehnung bedingte Relativbewegungen zwischen der Platte und der Innenwand des ausgekleideten Raumes möglich sind. Die bekannte Auskleidung eignet sich für Rauchgaskanäle aus Stahlblech, Gaswäscher u. dgl.. Eine durch Wärmedehnung bedingte Relativbewegung zwischen Auskleidung und Rauchgaskanal ist nur möglich, wenn die Innenwand des auszukleidenden Raumes ausreichend glatt ist. Für die Anordnung an einem unebenen, mit Fugen versehenen Futtermauerwerk eignet sich die bekannte Auskleidung nicht. Hinzu kommt, daß die Relativbewegung durch die Langlöcher im Fußflansch begrenzt ist und die Abmessungen der Langlöcher nach Maßgabe der Betriebstemperaturen und Rohrschußlänge bemessen werden müssen. Das ist aufwendig. Ferner schwächen die Langlöcher die Fußflansche und vergrößern den Gleitwiderstand der Auskleidung auf einem unebenen Untergrund.A GRP lining known from DE-C 42 26 902 consists of Slabs on the inner wall of a fluid-flow room be attached. The plates point in the longitudinal direction of the plate running webs with on the inner wall of the to be lined Screw-on foot flange. The fastening screws pass through elongated holes in the foot flange, so that through Relative movements between the plate caused by thermal expansion and the inner wall of the lined room are possible. The known lining is suitable for flue gas ducts Steel sheet, gas washer and. Like .. A due to thermal expansion Relative movement between the lining and the flue gas duct is only possible if the inner wall of the to be lined Room is sufficiently smooth. For placement on an uneven, with grooved lining masonry is suitable known lining not. Add to that the relative movement is limited by the elongated holes in the foot flange and the Dimensions of the elongated holes according to the operating temperatures and pipe section length must be measured. It is expensive. Furthermore, the elongated holes weaken the foot flanges and increase the sliding resistance of the lining on an uneven surface Underground.

Der Erfindung liegt die Aufgabe zugrunde, eine Schornsteinauskleidung zur Ertüchtigung eines vorhandenen Schornsteins für die Ableitung gewaschener Rauchgase anzugeben, die mit dünnwandigen Rohrschüssen geringer Formsteifigkeit ausführbar ist.The invention has for its object a chimney lining to upgrade an existing chimney for the discharge of washed flue gases, to be specified with thin-walled pipe sections with low dimensional rigidity is.

Die Aufgabe wird bei einer Auskleidung der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß an der Rückseite der Rohrschüsse in Umfangsrichtung mehrere in Rohrlängsrichtung sich erstreckende Stege angeformt sind, die einen winkelförmig anschließenden Fußflansch aufweisen, und daß die Fußflansche in Schiebesitzen, die in Rohrlängsrichtung beabstandet sind, geführt sowie an Festpunkten, die in einer Querschnittsebene des Rohrschusses angeordnet sind, an dem Futtermauerwerk befestigt sind, wobei die Schiebesitze jeweils aus einer an dem Futtermauerwerk befestigten Gleitplatte und einer den Fußflansch außenseitig fassenden Schiene bestehen. Das Gewicht der Rohrschüsse wird jeweils an den in einer Querschnittsebene angeordneten Festpunkten aufgenommen und in das Futtermauerwerk eingeleitet. Ferner sind die Rohrschüsse an einer Vielzahl von Schiebesitzen, die sowohl in Rohrlängsrichtung als auch am Umfang gleichmäßig verteilt angeordnet sind, gehalten. Auf die Schornsteinauskleidung wirkende Druckkräfte infolge des im Schornstein herrschenden Unterdrucks werden in gleichmäßiger Verteilung radial in das Futtermauerwerk eingeleitet. Aufgrund der gleichmäßigen Kraftverteilung können die Rohrschüsse dünnwandig und ohne zusätzliche außenseitige Verstärkungsringe ausgeführt werden und ist eine Schädigung des Futtermauerwerks nicht zu befürchten. Durch die erfindungsgemäß ausgebildeten Schiebesitze sind die Rohrschüsse in der Lage, sich in Rohrlängsrichtung frei auszudehnen. Große und auch schlagartig erfolgende Temperaturänderungen, die bei Ausfall einer dem Schornstein vorgeschalteten Rauchgasentschwefelungsanlage auftreten können, sind möglich und die daraus folgenden Dehnungen werden ohne störende Schubbeanspruchung des Futtermauerwerks in die Weichstoffkompensatoren eingeleitet.The task is described with a lining of the beginning Art solved according to the invention in that on the back the pipe sections in the circumferential direction several in the pipe longitudinal direction extending webs are formed, the one have an angular foot flange, and that the Foot flanges in sliding seats that are spaced in the longitudinal direction of the tube are, as well as at fixed points that are in a Cross-sectional plane of the pipe section are arranged on the Lining masonry are attached, the sliding seats each from a sliding plate attached to the lining masonry and a rail that grips the foot flange on the outside consist. The weight of the pipe sections is in each case in the fixed points arranged on a cross-sectional plane and introduced into the lining masonry. Furthermore, the pipe sections on a variety of sliding seats, both in Pipe longitudinal direction and evenly distributed around the circumference are arranged, held. On the chimney lining acting pressure forces due to the prevailing in the chimney Vacuum are distributed evenly in the radial direction Lining masonry initiated. Because of the even The pipe sections can be thin-walled and without force distribution additional reinforcement rings on the outside can be implemented and there is no fear of damage to the lining masonry. Due to the sliding seats designed according to the invention the pipe sections are able to move in the pipe longitudinal direction expand freely. Large and sudden Temperature changes in the event of failure of the chimney upstream flue gas desulfurization system occur can, are possible and the resulting strains are without disturbing shear stress on the lining masonry introduced into the soft expansion joints.

Gemäß einer bevorzugter Ausführung der Erfindung sind die Rohrschüsse aus dünnwandigen, bogensegmentförmigen Schalen zusammengesetzt, wobei die Stege an einer Längsseite der Schalen angeformt sind sowie einen Sattel für die Auflage einer umfangsseitig stufenlos anschließenden Schale aufweisen. Eine Vielzahl der bogensegmentförmigen Schalen sind in Umfangsrichtung nebeneinander angeordnet, wobei jede Schale einen Steg mit einem erfindungsgemäß in Schiebesitzen an dem Futtermauerwerk geführten Fußflansch aufweisen. Vorzugsweise decken die Schalen je nach Durchmesser des Schornsteins ein Bogensegment zwischen 15° und 45° ab.According to a preferred embodiment of the invention, the Pipe sections from thin-walled, segmented shells assembled, the webs on one long side of the Shells are molded and a saddle for the pad a continuously adjoining shell. A large number of the bowl-shaped shells are shown in Circumferentially arranged side by side, each shell a web with an inventive in sliding seats on the Have lining masonry guided foot flange. Preferably cover the shells depending on the diameter of the chimney Arc segment between 15 ° and 45 °.

In weiterer Ausgestaltung lehrt die Erfindung, daß die bogensegmentförmigen Schalen kürzer sind als die Rohrschüsse und eine Mehrzahl identisch ausgebildeter Schalen hintereinander angeordnet sind, wobei die Schalen in Rohrlängsrichtung sich überlappen und miteinander verbundene Abschnitte aufweisen. Zweckmäßig werden sie fluchtend, also ohne winkelförmigen Versatz, hintereinander angeordnet. Die Fugen zwischen den Schalen, sowohl der in Umfangsrichtung nebeneinander angeordneten als auch in Rohrlängsrichtung hintereinander angeordneten Schalen, sind durch Überlaminierung gasdicht geschlossen. Durch die Überlaminierung sind die Schalen auch kraftschlüssig miteinander verbunden.In a further embodiment, the invention teaches that the arc segment-shaped Shells are shorter than the pipe sections and a plurality of identical bowls in a row are arranged, the shells in the pipe longitudinal direction overlap and have interconnected sections. They are expediently aligned, that is to say without angular ones Offset, arranged one behind the other. The joints between the Shells, both side by side in the circumferential direction arranged as well as in the pipe longitudinal direction one behind the other arranged shells, are gas-tight due to overlamination closed. Due to the overlamination, the shells are too non-positively connected.

Die Festpunkte sind vorzugsweise in einem auf halber Länge des Rohrschusses angeordneten Querschnitt vorgesehen. Bei dieser Ausführung treten, ausgehend von dem Querschnitt, in dem die Festpunkte angeordnet sind, in der oberen und unteren Hälfte des Rohrschusses dem Betrage nach gleich große, jedoch unterschiedlich gerichtete Wärmedehnungen auf.The fixed points are preferably half-length of the pipe section arranged cross section provided. At this version, starting from the cross section, in where the fixed points are arranged, in the upper and lower Half of the pipe shot equal in amount, however differently oriented thermal expansions.

Eine bevorzugte konstruktive Ausführung der erfindungsgemäßen Schiebesitze sieht vor, daß die Schiene als Z-förmige Profilleiste ausgebildet und mit der Gleitplatte verschraubt ist, wobei die Schrauben Bohrungen der Gleitplatte durchfassen und im Futtermauerwerk verankert sind. An den Festpunkten sind die Fußflansche vorzugsweise unter Zwischenschaltung von Gleitplatten mittels Schrauben, welche die Bohrungen der Gleitplatten durchfassen, an dem Futtermauerwerk verankert.A preferred constructive embodiment of the invention Sliding seats provides that the rail as a Z-shaped profile bar trained and screwed to the slide plate, whereby the screws pass through holes in the sliding plate and are anchored in the lining masonry. Are at the benchmarks the foot flanges preferably with the interposition of Slide plates by means of screws, which the holes of the Grasp the sliding plates, anchored to the lining masonry.

Die Befestigung der vorgefertigten bogensegmentförmigen Schalen ist mit Hilfe der Gleitplatten und Schienen auf einfache Weise und rasch möglich. Aufwendige Laminierungsarbeiten an der Rückseite der Rohrschüsse sind nicht erforderlich. Überlaminierungen zwischen den bogensegmentförmigen Schalen können schnell und problemlos von der Innenseite des Schornsteinkanals aus vorgenommen werden. Stillstandzeiten für die Nachrüstung des Schornsteins können dadurch minimiert werden. Schließlich ist die erfindungsgemäße Auskleidung in der Lage, die aufgrund eines Unterdrucks im Schornsteinkanal herrschenden Druckkräfte aufzunehmen und ohne Spannungsspitzen gleichmäßig in das Futtermauerwerk einzuleiten.The attachment of the prefabricated arc segment-shaped Shells are on with the help of the sliding plates and rails simple and quick. Elaborate Lamination work is on the back of the pipe sections not mandatory. Overlaminations between the Bow-shaped bowls can be quickly and easily made from the inside of the chimney duct become. Downtimes for retrofitting the chimney can be minimized. After all, that is lining according to the invention capable of due to a Negative pressure prevailing in the chimney duct record and evenly without voltage peaks in the Initiate lining masonry.
