Description
Kohlenstaubfeuerung für Hochdruckkessel mit Dampferzeugung durch Einleitung überhitzten, aus dem Dampfraum selbst entnommenen Dampfes in das Wasser der Kesseltrommeln Die den Gegenstand der Erfindung bildende Kohlenstaubfeuerung, die insbesondere für nach dem Patent 46q.555 arbeitende Hochdruckkessel bestimmt ist, kennzeichnet sich dadurch, daß in dem Feuerraum U-förmige, von oberen Sammelrohren abzweigende Überhitzerrohre angeordnet sind, deren Querschenkel in verschiedener Höhenlage verlaufen und so dem Feuergasstrom freie Durchströmöffnungen nach den anschließenden Feuerzügen bieten, während die hängenden Schenkel Begrenzungswände für Flamme und Feuergasstrom bilden.Coal dust firing for high pressure boilers with steam generation by introduction superheated steam extracted from the steam room itself into the water of the boiler drums The pulverized coal furnace forming the subject of the invention, in particular is intended for high pressure boilers working according to patent 46q.555 by the fact that U-shaped branches branching off from the upper header pipes in the combustion chamber Superheater tubes are arranged, the transverse legs of which extend at different heights and thus the flow openings free for the flow of fire gas after the subsequent puffs of fire offer, while the hanging legs containment walls for flame and fire gas flow form.
Nach Big. i, die ein Ausführungsbeispiel der Anlage in einem senkrechten Schnitt veranschaulicht, sind in dem Feuerraum i U-förmige Überhitzerrohre 2 angeordnet, die von oberen Sammelrohren 3, 4 ausgehen und deren hängende Schenkel so aneinanderliegen, daß sie entweder allein oder nach Fig. 2 z. B. mit Hilfe angewalzter, angeschweißter oder sonstwie angebrachter Flossenstreifen 5 Begrenzungswände für den Feuerraum bis etwa zur Tiefe a-a bilden, während von da aus die OOuerschenkel abwechselnd in verschiedenen, nach Fig. i z. B. in drei Höhenlagen verlaufen, um dadurch dem Feuergasstrom Durchgangsöffnungen nach den anschließenden Feuerzügen zu bieten.After Big. i showing an embodiment of the plant in a vertical Section illustrated, U-shaped superheater tubes 2 are arranged in the combustion chamber i, which emanate from the upper header pipes 3, 4 and the hanging legs of which lie against one another, that they either alone or according to FIG. 2 z. B. with the help of rolled, welded or otherwise attached fin strips 5 boundary walls for the combustion chamber to about the depth a-a, while from there the outer thighs alternate in different, according to FIG. B. extend at three altitudes to thereby the Fire gas flow to provide passage openings after the subsequent fire puffs.
In dem zweiten Zuge können beispielsweise Rohrschlangenelemente 6 und 7 angeordnet werden, und zwar zunächst als Nachüberhitzer 6 und darüber als Wasservorwärmer 7 für das Speisewasser des Verdampfers.In the second step, for example, pipe coil elements 6 and 7 are arranged, initially as post-superheater 6 and above as Water preheater 7 for the feed water of the evaporator.
Der Dampf wird in bekannter Weise der Verdampftrommel8 entnommen und durch die Umlaufpumpe 9 den Sammelrohren 3 und dann den Überhitzerrohren 2 zugedrückt. Hierbei können U-förmige Rohre parallel-und Bündel solcher Rohre längs des Feuerraums hintereinandergeschaltet werden. Nach Passieren der Sammelrohre 4 und io gelangt der Dampf zum Nachüberhitzer 6 und zum Sammelrohr i i. Von hier aus wird ein Teil des Dampfes als Verbrauchsdampf D zur Dampfmaschine und der Rest in die Trommel 8 zur Bildung von Dampf aus ihrem Wasserinhalt geleitet.The steam is removed from the evaporation drum 8 in a known manner and The collector pipes 3 and then the superheater pipes 2 are pressed shut by the circulation pump 9. Here, U-shaped pipes can be parallel and bundles of such pipes along the combustion chamber can be connected in series. After passing the manifolds 4 and io arrives the steam to the post-superheater 6 and to the manifold i i. From here becomes a part of the steam as consumption steam D to the steam engine and the rest into the drum 8 directed to the formation of steam from their water content.
Das Speisewasser wird von der Speiseleitung b aus in dem aus parallel geschalteten Rohrelementen bestehenden Wasservorwärmer 7 vorgewärmt, von wo aus es ebenfalls der Verdampftromme18 zufließt. Ein Teil des Vorwärmers 7 kann auch im nachfolgenden dritten Feuerzug untergebracht werden. Im dritten Zug kann weiterhin der Luftvorwärmer 12 angeordnet werden, dem die Luft bei A zuströmt und von dem aus die vorgewärmte Verbrennungsluft den Kohlenstaubbrennern 13 über das Sammelrohr 14 zugeführt wird, während der Kohlenstaub den Brennern mittels von oben angeordneten Bunkern zuläuft.The feed water is from the feed line b from in parallel switched pipe elements existing water preheater 7 preheated, from where it also flows into the evaporation drum18. Part of the preheater 7 can also be accommodated in the following third fire train. On the third move you can continue the air preheater 12 to which the air flows at A and from which from the preheated combustion air to the pulverized coal burners 13 via the manifold 14 is fed, while the pulverized coal the burners by means of arranged from above Bunkers are coming.
Aus dem dritten Zug gelangen die Feuergase in den Fuchs und zum Schornstein.From the third puff, the fire gases get into the fox and the chimney.
