VGB Kraftswerkstechnik 73 (1993), pages 917 to 932 "known steam generator, the distribution channel connecting the outlet cross section of the air preheater with the inlet hoods is arranged horizontally. In addition, the air preheater is provided at the height of the dust burner, which is in boxed position on two opposite walls of the combustion chamber of the steam generator Oil lances are used in the dust burner, which are used to ignite the coal dust The arrangement of the air preheater in the burner level and the horizontal course of the distribution channel require a relatively large amount of space, which is associated with increased construction costs.

Der Erfindung liegt die Aufgabe zugrunde, den gattungsgemäßen Dampferzeuger so zu gestalten, daß dessen Bauaufwand verringert wird, ohne daß Qualitätseinbußen in Kauf genommen werden müssen.The invention has for its object the generic To design steam generator so that its construction costs is reduced without sacrificing quality Need to become.

Diese Aufgabe wird bei einem gattungsgemäßen Dampferzeuger erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. This task is carried out in a generic steam generator according to the invention by the characterizing features of Claim 1 solved. Advantageous embodiments of the Invention are the subject of the dependent claims.

Durch die Verlegung der Veteilerleitung in die Vertikale in Verbindung mit der Anordnung des Luftvorwärmers oberhalb der Brennerebenen wird der Platzbedarf der Dampferzeugeranlage auf zweierlei Weise verringert. Zum einen ist kein Abstand mehr erforderlich zwischen den Eintrittshaube des Elektrofilters und der Rückwand für den Anbau des Luftvorwärmers. Zum anderen kann der Luftvorwärmer nahe an der Brennkammerwand plaziert werden. Dadurch benötigt der Anbau bzw. das Gerüst für den Luftvorwärmer eine geringere Tiefe, was mit einer Verringerung an Stahlkonstruktion verbunden ist.By laying the distribution line in the vertical in Connection with the arrangement of the air preheater above the Burner levels will take up the space required by the steam generator system reduced in two ways. For one thing, there is no distance required between the inlet hood of the electrostatic filter and the rear wall for attaching the air preheater. On the other hand the air preheater can be placed close to the combustion chamber wall become. This means that the extension or scaffolding is required for the Air preheater to a shallower depth, resulting in a reduction is connected to steel structure.

Weitere Vorteile der Erfindung ergeben sich aus einem Ausführungsbeispiel, das in der Zeichnung dargestellt ist und der Erläuterung der Erfindung dient. Es zeigen:

  • Fig. 1 die Vorderansicht eines Dampferzeugers,
  • Fig. 2 die Draufsicht zu Fig. 1
    • Further advantages of the invention result from an exemplary embodiment which is shown in the drawing and serves to explain the invention. Show it:
  • 1 is a front view of a steam generator,
  • 2 shows the top view of FIG. 1

    • Der dargestellte Dampferzeuger ist als Turmkessel ausgebildet und weist eine durch Brennkammerwände 2 begrenzte Brennkammer 1 auf, an die sich ein Rauchgaszug 3 anschließt. Der Dampferzeuger kann auch als Mehrzugkessel mit mehreren hintereinander angeordneten Rauchgaszügen ausgebildet sein.The steam generator shown is designed as a tower boiler and has a combustion chamber delimited by combustion chamber walls 2 1, to which a flue gas duct 3 connects. The Steam generator can also be used as a multi-pass boiler with several flue gas flues arranged one behind the other.

    In zwei gegenüberliegenden Brennkammerwänden 2 sind in mehreren Ebenen übereinander Staubbrenner 4 angeordnet, in denen Kohlenstaub mit vorgewärmter Verbrennungsluft verbrannt wird. In der Längsachse der Staubbrenner 4 sind in bekannter Weise Öllanzen für die Zündung des Kohlenstaubes angeordnet. Diese Öllanzen müssen im Bedarfsfall zur Wartung aus den Staubbrenner ausgebaut werden können, wozu hinter den Staubbrennern genügend Platz für die Montage vorhanden sein muß.In two opposite combustion chamber walls 2 are in several levels one above the other, dust burner 4 arranged in which burned coal dust with preheated combustion air becomes. In the longitudinal axis of the dust burner 4 are known in Way oil lances arranged for the ignition of the coal dust. If necessary, these oil lances have to be taken out of maintenance Dust burner can be removed, what behind the There is enough space for dust burners for assembly got to.

    Eine oder mehrere Rauchgasleitungen 5 zur Abführung des in der Brennkammer 1 erzeugten Rauchgases verbinden den einzigen oder den letzten Rauchgaszug 3 mit einem von Rauchgas durchströmten Luftvorwärmer 6 zur Vorwärmung der Verbrennungsluft. Der Luftvorwärmer 6 weist ein zylindrisches Gehäuse 7 auf, in dem ein mit Speichermassen versehener Rotor umläuft. Das Gehäuse 7 ist mit einem Eintrittsstutzen 8 für Rauchgas, einem Austrittsstutzen 9 für Rauchgas, einem Eintrittsstutzen 10 für Verbrennungsluft und einem Austrittsstutzen 11 für Verbrennungsluft versehen.One or more flue gas lines 5 for discharging the in the Combustion chamber 1 generated flue gas connect the single or the last flue gas flue 3 with a flue gas flowing through it Air preheater 6 for preheating the combustion air. The Air preheater 6 has a cylindrical housing 7 in which a rotor provided with storage masses rotates. The housing 7 is with an inlet port 8 for flue gas, one Outlet nozzle 9 for flue gas, an inlet nozzle 10 for Combustion air and an outlet 11 for Provide combustion air.

    Der Luftvorwärmer 6 ist in einem Gerüst 12 angeordnet, das vertikale, auf einem Fundament aufgestellte Stützen 13, 14 aufweist und das an das den Dampferzeuger tragende Kesselgerüst 15 angebaut ist. Der Luftvorwärmer 6 befindet sich in einer Höhe oberhalb der Ebene der obersten Staubbrenner 4 und ist damit oberhalb des Ausbaubereiches der Öllanzen der Staubbrenner 4 angeordnet. Da auf den Ausbau der Öllanzen bei dieser Anordnung keine Rücksicht genommen zu werden braucht, wird der Luftvorwärmer 6 nahe an der Brennkammerwand 2 plaziert. Die Tiefe des Gerüstes 12 entspricht daher dem Abstand der rückwärtigen Wand des Luftvorwärmers 6 von der Achse der Stützen des Kesselgerüstes 15.The air preheater 6 is arranged in a frame 12, the vertical supports 13, 14 set up on a foundation has and that to the one carrying the steam generator Boiler frame 15 is attached. The air preheater 6 is located itself at a height above the top level Dust burner 4 and is therefore above the expansion area Oil lances of the dust burner 4 arranged. Since on the expansion of Oil lances are not taken into account with this arrangement need, the air preheater 6 is close to the Combustion chamber wall 2 placed. The depth of the scaffold 12 therefore corresponds to the distance of the rear wall of the Air preheater 6 from the axis of the supports of the boiler frame 15.

    Dem Luftvorwärmer 6 ist zur Reinigung des Rauchgases ein Elektofilter 16 nachgeschaltet. Der Elektrofilter 16 enthält ein Filtergehäuse 17, das mit einer oder mehreren Eintrittshauben 18 und einer oder mehreren Austrittshauben 19 versehen ist. Im dargestellten Fall sind zwei Eintrittshauben 18 und zwei Austrittshauben 19 vorgesehen.The air preheater 6 is for cleaning the flue gas Electro filter 16 downstream. The electrostatic filter 16 contains a filter housing 17 with one or more Entry hoods 18 and one or more exit hoods 19 is provided. In the case shown there are two entry hoods 18 and two outlet hoods 19 are provided.

    Die Eintrittshauben 18 des Elektrofilters 16 sind über eine Verteilerleitung 20 mit dem Rauchgasaustrittsstutzen 9 des Luftvorwärmers 6 verbunden. Diese Verteilerleitung 20 ist vertikal angeordnet und befindet sich innerhalb des Gerüstes 12 vertikal unterhalb des Rauchgasaustrittsstutzen 9. Die Eintrittshauben 18 ragen in das Gerüst 12 hinein. Das Filtergehäuse 17 des Elektrofilters 16 schließt auf der Zuströmseite mit der rückwärtigen Wand des Luftvorwärmers 6 bündig ab. Auf diese Weise ist im Vergleich zu einer herkömmlichen Dampferzeugeranlage mit einer waagerechten Verteilerleitung kein Abstand mehr zwischen der rückwärtigen Wand des Luftvorwärmers 6 und den Eintrittshauben 18 des Elektrofilters 16 erforderlich.The inlet hoods 18 of the electrostatic precipitator 16 are via a Distribution line 20 with the flue gas outlet 9 of the Air preheater 6 connected. This distribution line 20 is arranged vertically and located inside the scaffold 12 vertically below the flue gas outlet nozzle 9. Die Entry hoods 18 protrude into the frame 12. The Filter housing 17 of the electrostatic filter 16 closes on the Inflow side with the rear wall of the air preheater 6 flush. This is compared to one conventional steam generator system with a horizontal Distribution line no longer any distance between the rear Wall of the air preheater 6 and the inlet hoods 18 of the Electrofilter 16 required.

    Der rückwärtige Teil des Gerüstes 12 ist durch eine einzelne Stütze 14 gebildet, die in der Verlängerung der Längsachse des Elektrofilters 16 zentral zwischen den Eintrittshauben 18 angeordnet ist. Diese Stütze 14 dient gleichzeitig der Abstützung des Elektrofilters 16.The rear part of the frame 12 is by a single one Support 14 formed in the extension of the longitudinal axis of the Electrofilter 16 centrally between the inlet hoods 18th is arranged. This support 14 also serves Supporting the electrostatic filter 16.

    Außer der Verringerung des Bauaufwandes zeichnet sich der erfindungsgemäße Dampferzeuger durch eine Anzahl weiterer Vorteile aus. So ist aufgrund der vertikalen Anordnung der Verteilerleitung 20 die Rauchgasführung vom Dampferzeuger über den Luftvorwärmer 6 zum Elektrofilter 16 verschleißarm und verlustarm, woraus sich ein verringerter Eigenbedarf der Gesamtanlage ergibt. Die vertikale Anströmung des Elektrofilters 16 bewirkt eine günstige Grobstaubabscheidung vor dem Elektrofilter 16. Die in einer waagerechten Verteilerleitung bei Teillast stattfindende Staubspeicherung entfällt. Damit entfallen auch die Ausspeichereffekte bei einer Laststeigerung ebenso wie die statische Berücksichtigung der Staublast in der Verteilerleitung. Die in der vertikalen Verteilerleitung 20 angebrachten Kompensatoren sind weniger schmutzungs- und erosionsanfällig als die Kompensatoren in waagerechten Rohrleitungen.In addition to reducing construction costs, the steam generator according to the invention by a number of other Benefits from. So is due to the vertical arrangement of the Distribution line 20 the flue gas duct from the steam generator the air preheater 6 to the electrostatic filter 16 with little wear and low loss, resulting in a reduced personal need of Overall system results. The vertical flow of the Electrofilter 16 brings about a favorable coarse dust separation in front of the electrostatic filter 16. The in a horizontal Distribution line at partial load dust storage not applicable. This also eliminates the withdrawal effects a load increase as well as the static consideration the dust load in the distribution line. The one in the vertical Distribution line 20 attached compensators are fewer susceptible to dirt and erosion than the compensators in horizontal pipes.

    Durch den verringerten Abstand des Luftvorwärmers 6 und der Eintrittshauben 18 des Elektrofilters 16 von der Brennkammerwand 2 wird der Platzbedarf der gesamten Anlage geringer, der Fundamentaufwand reduziert, sowie die Distanzen für die Verbindungen der Infrastruktur, wie Kabelwege und Rohrleitungen kürzer. Die in dem Gerüst 12 vorhandenen Bühnen dienen gleichzeitig als Zugang zu dem Elektrofilter 16 und als Fluchtwege.Due to the reduced distance between the air preheater 6 and Entry hoods 18 of the electrostatic precipitator 16 from the Combustion chamber wall 2 becomes the space requirement of the entire system less, the foundation effort reduced, as well as the distances for the connections of the infrastructure, such as cable routes and Pipelines shorter. The stages in the scaffolding 12 serve both as access to the electrostatic filter 16 and as Escape routes.

    Die übliche Querdurchfahrt für Kraftfahrzeuge zwischen dem Gerüst 12 und dem Elektrofilter 16 ist bei dem erfindungsgemäßen Dampferzeuger weiterhin möglich und zwar jetzt unterhalb der Eintrittshauben 18.The usual cross passage for motor vehicles between the Scaffold 12 and the electrostatic filter 16 is in the Steam generator according to the invention still possible now below the inlet hoods 18.

    Wird eine Anlage zur Entstickung des Rauchgases vorgesehen, so läßt sich diese nahe an dem Kesselgerüst 15 plazieren.If a plant for the denitrification of the flue gas is provided, then it can be placed close to the boiler frame 15.

    Für ein eventuelles Waschen der Luftvorwärmers 6 werden zum Schutz des Elektrofilters 16 gegen Feuchtigkeit in die Eintrittshauben 18 temporär Schikanen und Planen eingebaut und für einen Wasserabführung über vorgeplante Anschlüsse gesorgt.For a possible washing of the air preheater 6 Protection of the electrostatic filter 16 against moisture in the Entry hoods 18 temporarily chicanes and tarpaulins installed and ensures water drainage via pre-planned connections.
