Description
Abhitzekessel zur Beheizung durch staubreiche Abgase mit einer zur Entstaubung der Abgase vorgeschalteten, die Kesselheizfläche bildenden Wirbelkammer Die Erfindung bezieht sich auf einen Abhitzekessel zur Beheizung durch staubreiche Abgase mit einer zur Entstaubung der Abgase vorgeschalteten, die Kesselheizfläche bildenden Wirbelkammer, bei der die Wirbelkammerwandung durch in den Kesselwasserkreislauf eingeschaltete Wasserrohre gebildet wird.Waste heat boiler for heating with dusty exhaust gases with a for Dust removal from the upstream swirl chamber forming the boiler heating surface The invention relates to a waste heat boiler for heating by dusty Exhaust gases with an upstream for dedusting the exhaust gases, the boiler heating surface forming vortex chamber, in which the vortex chamber wall through into the boiler water circuit switched water pipes is formed.
Derartige Anordnungen sind bekannt. Sie ' be= stehen aus einer mit Wasserrohren ausgekleideten Wirbelkammer, der ein Rauchröhrenkessel nachgeschaltet iis.t, durch dessen Rauchrohre die ausgewirbelten Abgase zur weiteren Abgabe ihres Wärmeinhalts abziehen. Um einen lohnenden Wärmeentzug aus den Abgasen zu sichern, muß aber der auf die Wirbelkammer aufgesetzte Abhitzekessel eine ganz erhebliche Baulänge haben und benötigt damit zu seiner Aufstellung viel Platz.Such arrangements are known. They 'consist of a with Swirl chamber lined with water pipes, followed by a smoke tube boiler iis.t, through whose smoke tubes the exhaust gases blown out for further discharge of their Subtract the heat content. In order to ensure a profitable extraction of heat from the exhaust gases, but the waste heat boiler placed on the vortex chamber must have a very considerable amount Have overall length and therefore require a lot of space to set up.
Diesem Bekannten gegenüber besteht die Erfindung darin, daß die die Wirbelkammer bildenden Wasserrohre den aus der Decke und der feuer-@bücJhsartig nach innen gezogenen Wandung bestehenden Kesseloberteil mit dem den Raum zur Endauswirbelung der Abgase bildenden Kesselunterteil verbinden.Against this acquaintance, the invention consists in that the Vortex chamber forming water pipes from the ceiling and the feuer- @ bücJhsartig inwardly drawn wall existing boiler shell with the space for the final turbulence the lower part of the boiler forming the exhaust gases.
Durch die erfindungsgemäße Ausführung, bei der die Wirbelkammer als den oberen und den unteren Kesselteil miteinander verbindendes Glied ausgebildet ist, wird der als unterer Kesselteil ausgebildete Raum unter dem Wirbelkammerteil, der der Endauswirbelung der Abgase dient, in vorteilhafter Weise zur Aufnahme von Wärme aus den Abgasen mit herangezogen. Hierdurch wird nicht nur eine Steigerung der Nutzwärmegewinnung herbeigeführt, sondern auch eine raumsparende gedrungene Bauweise der Einrichtung erzielt.Due to the embodiment according to the invention, in which the vortex chamber as the upper and lower boiler parts are formed connecting members is designed as the lower part of the boiler Space under the Vortex chamber part, which is used for the final swirling of the exhaust gases, in an advantageous manner used to absorb heat from the exhaust gases. This not only does brought about an increase in useful heat recovery, but also a space-saving one compact construction of the facility achieved.
Ein Erfindungsbeispiel ist in der Zeichnung in Fig. i in einem Achsenlängsschnitt und in Fig. 2 in einem Schnitt nach Linie II-II der Fig. i dargestellt.An example of the invention is shown in the drawing in Fig. I in an axial longitudinal section and shown in FIG. 2 in a section along line II-II of FIG.
Der mit der Wirbelkammer zusammengebaute Abhitzekessel hat einen Oberteil i, der aus einer seitlich herabgezogenen Decke :2 und einer feuerbüchsartig nach innen gezogenen Wandung 3 zusammengesetzt ist. Der Kesseloberteil i umschließt einen Raum 4. Rauchrohre 5 verbinden den Raum 4 mit dem Gasabführraum 6, der über dem Oberteil i angeordnet und mit dem Abgasaustrittsstutzen 7 versehen ist. Unterhalb des Oberteils i ist die Wirbelkammer 8 angeordnet. Ihre Wandung wird aus Rohren 9 gebildet, die den Kesseloberteil i mit einem Kesselunterteil io verbinden. Die Rohre 9 sind so angeordnet, daß, z. B. bei tangentialem Eintritt der Abgase in die Wirbelkammer 8, der Abgaseintritt i i durch die Rohre 9 begrenzt wird. Der sich der Wirbelkammer 8 anschließende Kesselunterteil io umschließt einen Raum 12, in dem die Endauswirbelung der Gase erfolgt. Dieser -Kesselunterteil kann ebenso wie die danüberliegende Wirbelkammer 8 zylindrischen Querschnitt haben. Vorteilhaft ist ein spiralförmiger Querschnitt, da dieser die Wirbelbewegung und die Staubabscheidung begünstigt. Unterhalb des Raumes 12 bzw. des Kesselunterteiles io ist der Staubsammel- oder Staubabführungstrichter-13 angeordnet, der durch einen beweglichen Verschlußkörper 14 in bekannter Weisse verschließbar ist. Zur Reingasableitung dient das Abgasleitrohr 15. Das Abgasleitrohr 15 ist in der Mittelachse des Abhitzekessels angeordnet und verbindet den Raum 12 mit dem Raun' 4.The waste heat boiler, which is assembled with the swirl chamber, has an upper part i, the one from a ceiling pulled down to the side: 2 and a firebox-like after inside drawn wall 3 is composed. The boiler shell i encloses one Room 4. Flue pipes 5 connect the room 4 with the gas discharge space 6, which is above the Upper part i is arranged and provided with the exhaust gas outlet connection 7. Below the swirl chamber 8 is arranged in the upper part i. Its wall is made of pipes 9 formed, which connect the boiler upper part i with a boiler lower part io. the Pipes 9 are arranged so that, for. B. with tangential entry of the exhaust gases into the Vortex chamber 8, the exhaust gas inlet i i is limited by the pipes 9. Which the swirl chamber 8 adjoining the lower part of the boiler io encloses a space 12 in where the final swirling of the gases takes place. This boiler base can as well as the vortex chamber 8 lying next to it have a cylindrical cross-section. Advantageous is a spiral cross-section, as this is the vortex movement and dust separation favored. The dust collector is located below room 12 or the lower part of the boiler or dust discharge funnel-13 arranged by a movable closure body 14 can be closed in a known white. The exhaust pipe serves to discharge the clean gas 15. The exhaust pipe 15 is arranged in the central axis of the waste heat boiler and connects the room 12 with the room 4.
Durch den Abgaseintritt i i tritt das zu entstaubende heiße Abgas tangential in die durch die Rohre 9 umschlossene Wirbelkammer 8 ein. Zur Erzielung einer glatten Wandung sind die Rohre 9 mit Schamotte belegt oder sonstwie mit einer glatten, feuerfesten Verkleidung versehen. Durch Fliehkraftwirkung werden die in dem Abgas enthaltenen Staubteilchen an die Wandungen . der Wirbelkammer 8 und die des durch den Kesselunterteil io gebildeten Raumes 12 geführt und fallen in den Staubabführungstrichter 13, aus dem sie durch Offnen des Verschlusses 14 von Zeit zu Zeit abgezogen werden. Das Reingas zieht durch das Abgasleitrohr 15 in den Raum 4 und weiter durch die Rauchrohre 5 über den Gasabführraum 6 zum Abgasstutzen 7.The hot exhaust gas to be dedusted passes through the exhaust gas inlet i i tangentially into the swirl chamber 8 enclosed by the tubes 9. To achieve a smooth wall, the pipes 9 are covered with chamotte or otherwise with a smooth, fireproof cladding. Due to the effect of centrifugal force, the in the exhaust gas contained dust particles on the walls. the vortex chamber 8 and the of the space 12 formed by the lower boiler part io and fall into the Dust discharge funnel 13, from which it can be opened by opening the shutter 14 from time to time to be deducted at time. The clean gas pulls through the exhaust pipe 15 into the room 4 and further through the smoke tubes 5 via the gas discharge space 6 to the exhaust gas nozzle 7.
Auf dem vorbeschriebenen Wege geben die heißen Abgase einen Teil ihres Wärmeinhaltes an die Kesselwandungen und damit an den Kesselinhalt ab. Der sich bildende Dampf wird durch den Stutzen 16 abgeleitet und kann z. B. als Heizdampf Verwendung finden. Der Weg der Abgase ist durch Pfeile angedeutet.In the way described above, the hot exhaust gases give off part of theirs Heat content to the boiler walls and thus to the boiler content. Which forming steam is discharged through the nozzle 16 and can, for. B. as heating steam Find use. The path of the exhaust gases is indicated by arrows.
