Abstract

Der Dampferzeuger hat einen Gaszug (1) von rechteckigem Querschnitt. Die Wände des Gaszuges bestehen aus miteinander gasdicht verschweissten Rohren (3). Am unteren Ende des Gaszuges ist ein ebenfalls aus miteinander gasdicht verschweissten Rohren (13) gebildeter Trichter (2) angeordnet, der aus vier ebenen, trapezförmigen, schrägen Wänden (2a, 2b) zusammengesetzt ist. Die unteren Enden der Trichterwände begrenzen eine rechteckige Austrittsöffnung (4). Hierdurch wird es möglich, den Trichter nicht nur hinsichtlich der Breite seiner Austrittsöffnung, sondern auch der Länge an Ascheaustraganlagen anzupassen, die unterhalb der Trichteröffnung angeordnet sind.The steam generator has a throttle cable (1) with a rectangular cross section. The walls of the throttle cable consist of tubes (3) welded together in a gas-tight manner. At the lower end of the throttle cable there is a funnel (2), which is also formed from tubes (13) welded to one another in a gas-tight manner and is composed of four flat, trapezoidal, sloping walls (2a, 2b). The lower ends of the funnel walls delimit a rectangular outlet opening (4). This makes it possible to adapt the funnel not only with regard to the width of its outlet opening, but also the length of ash discharge systems which are arranged below the funnel opening.

Description

Die Erfindung betrifft einen Dampferzeuger mit einer Feuerung für feste Brennstoffe, mit einem einen recht­eckigen Querschnitt aufweisenden, aus miteinander gas­dicht verschweissten Rohren gebildeten, vertikalen Gas­zug, an dessem unteren Ende ein ebenfalls aus miteinander gasdicht verschweissten Rohren gebildeter Trichter ange­ordnet ist, der aus vier ebenen Wänden zusammengesetzt ist und an seinem unteren Ende eine rechteckige Austritts­öffnung aufweist, wobei die Rohre des Gaszuges und die Rohre des Trichters miteinander kommunizieren und vom Ar­beitsmittel von unten nach oben durchströmt sind und wo­bei die Rohre des Trichters schraubenlinienförmig ge­wickelt sind.The invention relates to a steam generator with a firing for solid fuels, with a vertical gas train having a rectangular cross-section, formed from tubes gas-welded to one another, at the lower end of which a funnel is also formed from tubes gas-welded to one another, which consists of four flat walls is assembled and has a rectangular outlet opening at its lower end, the pipes of the throttle cable and the pipes of the funnel communicate with one another and through which the working fluid flows from bottom to top and the pipes of the funnel are wound in a helical manner.

Bei einem bekannten Dampferzeuger dieser Art besteht der Trichter aus zwei einander gegenüberliegenden, vertikalen, trapezförmigen Wänden und zwei einander gegenüberliegen­den, schrägen, rechteckigen Wänden, wobei die am unteren Ende dieser vier Wände befindliche rechteckige Austritts­öffnung so lang ist wie die Länge jeder schrägen Rechteck­ wand. Die beiden vertikalen, trapezförmigen Wände bilden also fluchtende Verlängerungen zweier zueinander para­leller Wände des Gaszuges und begrenzen mit ihrem unteren Ende je eine kurze Seite der rechteckigen Austrittsöffnung. Dieser Dampferzeuger hat sich wegen seiner konstruktiven und herstellungsmässigen Einfachheit in der Praxis im all­gemeinen bewährt. Er ermöglicht auf einfache Weise eine An­passung der Breite der Austrittsöffnung an die Bedürfnisse der daran anschliessenden Anlagen zum Austragen der Asche, so dass beim Auslegen dieser Anlagen die Länge der Austritts­öffnung berücksichtigt werden muss. Dies erschwert das Er­stellen solcher Anlagen, die üblicherweise aus Normteilen zusammengebaut werden.In a known steam generator of this type, the funnel consists of two opposite, vertical, trapezoidal walls and two opposite, oblique, rectangular walls, the rectangular outlet opening at the lower end of these four walls being as long as the length of each oblique rectangle wall. The two vertical, trapezoidal walls thus form aligned extensions of two parallel walls of the throttle cable and each delimit a short side of the rectangular outlet opening with their lower end. This steam generator has generally proven itself in practice because of its design and manufacturing simplicity. It enables the width of the outlet opening to be adapted in a simple manner to the needs of the adjoining systems for discharging the ash, so that the length of the outlet opening must be taken into account when laying out these systems. This makes it difficult to create systems that are usually assembled from standard parts.

Der Erfindung liegt die Aufgabe zugrunde, einen Dampferzeu­ger der eingangs genannten Gattung so zu verbessern, dass das Auslegen und das Erstellen der an die Trichteraustritts­öffnung anschliessenden Ascheaustraganlagen vereinfacht wird.The invention has for its object to improve a steam generator of the type mentioned in such a way that the laying out and the creation of the ash discharge systems connected to the funnel outlet opening is simplified.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass alle Wände des Trichters trapezförmig ausgebildet sind. Durch diese Gestaltung wird es möglich, den Trichter auch hinsichtlich der Länge seiner Austrittsöffnung an die Asche­austraganlagen anzupassen, so dass diese problemlos aus Normteilen zusammengebaut werden können. Es hat sich gezeigt, dass dies kostengünstiger zu bewerkstelligen ist, als die bisher übliche Anpassung der Ascheaustraganlagen an die Trichteraustrittsöffnung. Diese Vorteile kommen auch dann zur Geltung, wenn ein bisher ölbefeuerter Dampferzeuger auf Kohlefeuerung umgerüstet werden soll.This object is achieved according to the invention in that all walls of the funnel are trapezoidal. This design makes it possible to adapt the hopper to the ash discharge systems with regard to the length of its outlet opening, so that they can be assembled from standard parts without any problems. It has been shown that this can be done more cost-effectively than the customary adaptation of the ash discharge systems to the funnel outlet opening. These advantages also come into play when a previously oil-fired steam generator is to be converted to coal firing.

Eine vorteilhafte Weiterbildung der Erfindung ist im Anspruch 2 offenbart. Bei seiner Anwendung ist es möglich, einen gleichmässigen Abstand zwischen den schraubenlinien­förmig gewickelten Rohren aller Trichterwände einzuhalten.An advantageous development of the invention is disclosed in claim 2. When used, it is possible to maintain an even distance between the helically wound tubes of all funnel walls.

Ein Ausführungsbeispiel der Erfindung ist in der folgen­den Beschreibung anhand der Zeichnung näher erläutert. Es zeigen in schematischer Darstellung:

  • Fig. 1 eine perspektivische Ansicht eines Dampferzeugers nach der Erfindung,
  • Fig. 2 einen Grundriss des Dampferzeugers nach Fig. 1 und
  • Fig. 3 eine Abwicklung des Dampferzeugers.
An embodiment of the invention is explained in more detail in the following description with reference to the drawing. In a schematic representation:
  • 1 is a perspective view of a steam generator according to the invention,
  • Fig. 2 is a plan view of the steam generator according to Fig. 1 and
  • Fig. 3 is a development of the steam generator.

Der Dampferzeuger weist einen vertikalen Gaszug 1 mit quadratischem Querschnitt auf. Der Gaszug ist aus Rohren 3 gebildet, die über Stege 30 (Fig. 3) gasdicht mitein­ander verschweisst sind. Am unteren Ende des Gaszuges 1 ist ein Trichter 2 angeordnet, der ebenfalls aus über Stege 33 gasdicht miteinander verschweissten Rohren 13 gebildet ist. Der Trichter 2 weist vier ebene, trapez­förmige, schräge Wände 2a und 2b auf, die mit ihren unteren, horizontalen Rändern eine rechteckige Austritts­öffnung 4 begrenzen. Den kurzen Seiten der Austritts­öffnung 4 sind die beiden unter sich gleichen Wände 2a und den langen Seiten die beiden ebenfalls unter sich gleichen Wände 2b zugeordnet, die aber von den Trichter­wänden 2a verschieden sind. Die Rohrwände des Gaszuges 1 und des Trichters 2 gehen gasdicht ineinander über, wo­bei die Rohre 13 des Trichters 2 und die Rohre 3 des Gaszuges 1 schraubenlinienförmig gewickelt sind. Das diese Rohre durchströmende Arbeitsmittel wird am unteren Ende der Rohre 13 zugeführt und am oberen Ende der Rohre 3 entnommen, so dass es von unten nach oben strömt. Nicht gezeigte Kohlenstaubbrenner sind auf bekannte Weise im Bereich der vertikalen Kanten des Gaszuges 1 angeordnet und bilden eine Tangentialfeuerung des Dampf­erzeugers.The steam generator has a vertical throttle cable 1 with a square cross section. The throttle cable is formed from tubes 3, which are welded together in a gas-tight manner via webs 30 (FIG. 3). At the lower end of the throttle cable 1, a funnel 2 is arranged, which is also formed from tubes 13 welded to one another in gas-tight fashion via webs 33. The funnel 2 has four flat, trapezoidal, oblique walls 2a and 2b, which delimit a rectangular outlet opening 4 with their lower, horizontal edges. The short sides of the outlet opening 4 are assigned the two walls 2a which are the same and the long sides the two walls 2b which are also the same but which are different from the funnel walls 2a. The tube walls of the throttle cable 1 and the funnel 2 merge into one another in a gas-tight manner, the tubes 13 of the funnel 2 and the tubes 3 of the throttle cable 1 being wound helically. The working fluid flowing through these tubes is fed in at the lower end of the tubes 13 and removed at the upper end of the tubes 3, so that it flows from the bottom to the top. Coal dust burners, not shown, are arranged in a known manner in the region of the vertical edges of the throttle cable 1 and form a tangential combustion of the steam generator.

In der Abwicklung gemäss Fig. 3 schliessen die schrägen Kanten der Trichterwände 2a einen Windel α und die schrägen Kanten 22 der Trichterwände 2b einen Winkel β jeweils mit der Vertikalen ein. Die Rohre 13 weisen in den Trichterwänden 2a gegenüber der Horizontalen eine Neigung δ auf, die die Rohre 13 mehrheitlich auch in den Trichterwänden 2b haben. Lediglich die zwischen der jeweils in Fig. 3 linken schrägen Kante 22 der Trichter­wände 2b und einer diese Kante am Uebergang des Trichters zum Gaszug schneidenden Grenzgeraden 5 befindlichen Ab­schnitte der Rohre 13 weisen gegenüber der Horizontalen eine Uebergangs-Neigung ε auf. Diese Uebergangs-Neigung ist grösser als die Neigung δ. Dadurch wird ein steti­ger Uebergang der Rohre 13 der Trichterwände 2b zu den benachbarten Wänden 2a gewährleistet. Jede Grenzgerade 5 schliesst mit der Vertikalen einen Winkel γ ein. Um ferner einen konstanten Abstand t zwischen den einzelnen Rohren 13 im ganzen Trichter 2 zu erhalten, weisen die Winkel zugleich folgende Beziehungen zueinander auf:
β = α - 2δ
γ = α
ε = 2α - δ3, the inclined edges of the funnel walls 2a enclose a diaper α and the inclined edges 22 of the funnel walls 2b form an angle β with the vertical. The tubes 13 have an inclination δ in the funnel walls 2a relative to the horizontal, which the majority of the tubes 13 also have in the funnel walls 2b. Only the sections of the tubes 13 between the oblique edge 22 of the funnel walls 2b on the left in FIG. 3 and a boundary line 5 intersecting this edge at the transition of the funnel to the gas flue have a transition inclination ε with respect to the horizontal. This transition slope is greater than the slope δ. This ensures a constant transition of the tubes 13 of the funnel walls 2b to the adjacent walls 2a. Each boundary line 5 forms an angle γ with the vertical. In order to further maintain a constant distance t between the individual tubes 13 in the entire funnel 2, the angles also have the following relationships to one another:
β = α - 2δ
γ = α
ε = 2α - δ

In Fig. 3 beträgt der Winkel α 30°. Er liegt somit unterhalb des Grenzwertes von 35°, bei dem noch ein gutes Abfliessen von zähen Verbrennungsrückständen, ins­besondere Asche, im Trichter stattfindet.In Fig. 3, the angle α is 30 °. It is therefore below the limit of 35 °, at which there is still a good drainage of viscous combustion residues, especially ash, in the funnel.

Dadurch, dass auch die die kurzen Seiten der Austritts­öffnung 4 begrenzenden Trichterwände 2a schräg verlaufen, lässt sich beim Auslegen des Dampferzeugers die Länge der Austrittsöffnung an die sich an diese anschliessende, nicht dargestellte Anlage zum Austragen der Verbrennungs­rückstände in einfacher Weise anpassen. Diese Anlagen können dann ohne Schwierigkeiten aus den Normteilen zu­sammengebaut werden.Because the funnel walls 2a delimiting the short sides of the outlet opening 4 also run obliquely, when the steam generator is laid out, the length of the outlet opening can be adapted in a simple manner to the adjoining, not shown, system for discharging the combustion residues. These plants can then be assembled from the standard parts without difficulty.

Abweichend von dem Beschriebenen Ausführungsbeispiel kann der Gaszug auch einen vom quadratischen Querschnitt abweichenden rechteckigen Querschnitt aufweisen.In a departure from the described exemplary embodiment, the accelerator cable can also have a rectangular cross section that deviates from the square cross section.
