Description
Die Erfindung betrifft einen Heizungskessel für flüssige oder gasförmige Brennstoffe gemäss Oberbegriff des Patentanspruches 1. The invention relates to a heating boiler for liquid or gaseous fuels according to the preamble of claim 1.
Heizungskessel der genannten Art sind nach der DE-OS 28 24 185 bekannt. Der Anordnung eines Wärmetauschers hinter der topfförmigen Brennkammer liegt der Gedanke zugrunde, den Leistungsbereich derartiger Kessel vergrössem zu können, ohne dabei den Heizungskessel entsprechend vergrössem bzw. verlängern zu müssen, was notwendig wäre, wenn man keinen Wärmetauscher hinter den Nachschaltheiz-flächen anordnen würde. Boilers of the type mentioned are known from DE-OS 28 24 185. The arrangement of a heat exchanger behind the pot-shaped combustion chamber is based on the idea of being able to increase the output range of such boilers without having to increase or lengthen the heating boiler accordingly, which would be necessary if one did not arrange a heat exchanger behind the secondary heating surfaces.
Der Einbau eines solchen Wärmetauschers wird jedoch sehr problematisch, wenn aus Korrosionsschutzgründen in den Feuerraum eines Heizungskessels ein rohrförmiger Gusseinsatz eingebaut ist. However, the installation of such a heat exchanger becomes very problematic if, for corrosion protection reasons, a tubular cast insert is installed in the combustion chamber of a heating boiler.
Der Erfindung liegt demgemäss die Aufgabe zugrunde, einen Heizungskessel der eingangs genannten Art dahingehend zu verbessern, dass trotz korrosionsfester Ausbildung des ganzen rauchgasführenden Innenteiles in Form eines Gusseinsatzes, der Einbau des Wärmetauschers, der entsprechend korrosionsgeschützt und gut mit der den Feuerraum um-schliessenden Wand des wasserführenden Stahlblechgehäuses verbindbar sein soll, überhaupt machbar wird, ohne dabei komplizierte Gussausformungen im Einbaubereich des Wär-5 metauschers vorsehen zu müssen. The invention is therefore based on the object to improve a boiler of the type mentioned in such a way that despite the corrosion-resistant design of the entire flue gas-carrying inner part in the form of a cast insert, the installation of the heat exchanger, which is correspondingly protected against corrosion and well with the wall surrounding the combustion chamber water-bearing sheet steel housing should be connectable, is even feasible without having to provide complicated castings in the installation area of the heat exchanger.
Diese Aufgabe ist mit einem Heizungskessel der eingangs genannten Art nach der Erfindung durch das im Kennzeichen des Patentanspruches 1 Erfasste gelöst. This object is achieved with a heating boiler of the type mentioned at the outset according to the invention by what is stated in the characterizing part of patent claim 1.
Vorteilhafte Weiterbildungen ergeben sich nach den ab-iohängigen Ansprüchen. Advantageous further developments result from the dependent claims.
Der erfindungsgemässe Heizungskessel wird nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert. The heating boiler according to the invention is explained in more detail below with the aid of exemplary embodiments.
i5 Es zeigen schematisch i5 It shows schematically
Fig. 1 im Schnitt den erfindungsgemässen Heizungskessel; Fig. 1 in section the boiler according to the invention;
Fig. 2 einen Schnitt durch den Heizungskessel längs Linie II-II gemäss Fig. 1 und Fig. 2 shows a section through the boiler along line II-II of FIG. 1 and
Fig. 3 einen Schnitt längs Linie III-III gemäss Fig. 1. 20 Der Heizungskessel 15 ist, wie erkennbar, bis auf die Einbauten im rohrförmigen Einsatz 2 eine reine Stahlblechkonstruktion, wobei die Vorder- und Rückwand 16,17 vom rohrförmigen Einsatz 2 flüssigkeitsdicht durchgriffen wird. Bei den Einbauten handelt es sich dabei um die Umkehrbrenn-25 kammer 19, die Hülse 6 aus Guss mit den Rippen 18, den Hülsen teil 6', ebenfalls aus Guss, und um den Wärmetauscher 1. 3 shows a section along line III-III according to FIG. 1. 20 As can be seen, the heating boiler 15 is, apart from the internals in the tubular insert 2, a pure steel sheet construction, the front and rear walls 16, 17 of the tubular insert 2 being liquid-tight is penetrated. The internals are the reverse combustion chamber 19, the sleeve 6 made of cast iron with the ribs 18, the sleeve part 6 ', also made of cast iron, and the heat exchanger 1.
Der ringförmige Heizgaszug ist durch Rippen 18 ringsum in einzelne Heizgaszüge 3' gegliedert und wird radial nach 30 aussen vom rohrförmigen Einsatz 2 und radial nach innen von der Umkehrbrennkammer 19 begrenzt. The annular heating gas flue is divided into individual heating gas flues 3 ′ by ribs 18 and is delimited radially outwards by the tubular insert 2 and radially inwards by the reversing combustion chamber 19.
Im verbleibenden Freiraum zwischen den Rippen 18 ist die topfartige Brennkammer 19 eingesetzt, die nach Öffnung des vorderen Verschlussdeckels 20 nach vorn herausgezogen 35 werden kann. Zwischen dem Boden 21 der Brennkammer 19 und dem hinteren Verschlussdeckel 22 sind die Nachschalt-heizflächen 3 in Form eines Wärmetauschers 1 angeordnet, der bspw. aus drei Stahlrohren 4 besteht, die den rohrförmigen Einsatz 2 flüssigkeitsdicht durchgreifen und die jeweils in 40 einem Rippenkörper 5 aus Guss mit eingegossen sind. Um die Heizgase nicht durch die seitlich verbleibenden Freiräume zwischen Wärmetauscher 1 und rohrförmigem Einsatz 2 bevorzugt abströmen zu lassen, sind dort Abschirmungen 10 vorgesehen. Wie erkennbar, lässt sich auf diese Weise eine re-45 lativ grosse Nachschaltheizfläche 3 unterbringen, ohne die bei gleicher Heizkesselleistung der rohrförmige Einsatz 2 und die Brennkammer 19 im Durchmesser und/oder in der Länge wesentlich grösser angelegt werden müssten. In the remaining free space between the ribs 18, the pot-like combustion chamber 19 is inserted, which can be pulled out 35 to the front after opening the front cover 20. Between the bottom 21 of the combustion chamber 19 and the rear cover 22, the secondary heating surfaces 3 are arranged in the form of a heat exchanger 1, which consists, for example, of three steel tubes 4, which pass through the tubular insert 2 in a liquid-tight manner and each of which consists of a rib body 5 in 40 Are cast in. In order not to allow the heating gases to flow preferentially through the free spaces remaining laterally between the heat exchanger 1 and the tubular insert 2, shields 10 are provided there. As can be seen, a relatively large secondary heating surface 3 can be accommodated in this way, without the tubular insert 2 and the combustion chamber 19 having to be made much larger in diameter and / or in length with the same boiler output.
Im rohrförmigen Einsatz 2 ist die dünnwandige Hülse 6 so aus Guss eingesetzt, an der die Rippen 18 für die Gliederung der Heizgaszüge 3' gleich mit angegossen sind, wobei der Abzugsbereich hinter dem Boden 21 der Brennkammer 19 natürlich frei von Rippen 18 gehalten ist. In the tubular insert 2, the thin-walled sleeve 6 is inserted from cast iron, on which the ribs 18 for the structure of the heating gas flues 3 'are also cast on, the extraction area behind the bottom 21 of the combustion chamber 19 being, of course, kept free of ribs 18.
Wie aus Fig. 1,2 erkennbar, ist die Hülse 6 zweiteilig aus-55 gebildet, wobei der hintere, nur im Bereich der Nachschalt-heizflächen 3 angeordnete, mit den Durchgriffsöffnungen 7 versehene Hülsenteil 6' einen gegenüber dem rohrförmigen Einsatz reduzierten Durchmesser aufweist, das vordere Teil der Hülse 6 abzugsseitig mit einem durchmesserreduzierten 60 Bund und das durchmesserreduzierte hintere Hülsenteil 6' mit einem über diesem Bund passenden Anschlussbund 9 versehen ist. As can be seen from FIG. 1, the sleeve 6 is formed in two parts from 55, the rear sleeve part 6 ′, which is arranged only in the area of the secondary heating surfaces 3 and is provided with the passage openings 7, has a diameter which is reduced compared to the tubular insert, the front part of the sleeve 6 is provided on the take-off side with a reduced-diameter 60 collar and the reduced-diameter rear sleeve part 6 'is provided with a connecting collar 9 which fits over this collar.
Femer sind die Abschirmungen 10 am hinteren Hülsenteil 6' mit angeformt und ebenso der Rauchgasabzugsstutzen 11, «s wobei die den Rauchgasabzugsstutzen 11 bildende Verlängerung mit einer ihrem Gesamtquerschnitt etwa entsprechenden Öffnung 12 versehen und diese sich in einer Ebene erstreckt, die von oben nach unten zur Rückwand 17 des Stahlblechge Furthermore, the shields 10 are integrally formed on the rear sleeve part 6 'and likewise the flue gas outlet connection 11, the extension forming the flue gas outlet connection 11 being provided with an opening 12 which approximately corresponds to its overall cross section and which extends in a plane which extends from top to bottom to Rear wall 17 of the steel sheet
häuses 15 hin geneigt verläuft. Der Rauchabgang erfolgt nach oben durch den Anschlussstutzen 23. housing 15 runs inclined. The smoke is discharged upwards through the connecting piece 23.
Die Öffnung 12 ist mit einem Verschlussdeckel 22 versehen, nach dessen Öffnung der gesamte Querschnitt des Hülsenteiles 6' und die Nachschaltheizflächen 3 in Form eines Wärmetauschers 1 zur Reinigung freiliegen. Die flüssigkeitsdichte Verbindung der Enden der Rohre 4 aus Stahl mit dem rohrförmigen Einsatz 2 erfolgt im Bereich von Einprägungen 24. The opening 12 is provided with a closure cover 22, after the opening of which the entire cross section of the sleeve part 6 'and the secondary heating surfaces 3 in the form of a heat exchanger 1 are exposed for cleaning. The liquid-tight connection of the ends of the pipes 4 made of steel with the tubular insert 2 takes place in the region of the impressions 24.
Bei dieser Ausbildung können also die Nachschaltheizflä-chen 3 und der ganze Abzugsteil separat fertiggestellt und in den hinteren Teil des rohrförmigen Einsatzes 2 im Sinne der Fig. 1 eingesetzt werden und zwar unter Erfassung aller notwendigen Massnahmen zur Beherrschung des besonders kondensatkritischen Abzugsbereiches, nämlich Unterbindung ei3 648 925 In this configuration, the Nachschaltheizflä-chen 3 and the entire fume cupboard part can be finished separately and inserted in the rear part of the tubular insert 2 in the sense of FIG. 1, taking into account all measures necessary to control the particularly condensate-critical fume cupboard area, namely prevention ei3 648 925
nes unmittelbaren Wärmeüberganges vom hinteren Hülsenteil 6' an die Wandung des rohrförmigen Einsatzes 2, indem durch die Durchmesserreduzierung ein Spalt 25 gebildet wird. Nes direct heat transfer from the rear sleeve part 6 'to the wall of the tubular insert 2 by a gap 25 is formed by the diameter reduction.
5 Vorteilhaft ist das hintere Hülsenteil 6' zweiteilig in Form einer oberen und unteren Hälfte 13,14 ausgebildet, wodurch die Einbringung des Wärmetauschers 1 in den daraus zusammengesetzten hinteren Hülsenteil 6' wesentlich vereinfacht ist, da die beiden Hälften 13,14 mit ihren Durchgriffsöffnungen 7 io einfach auf die Enden der Stahlrohre 4 gesteckt werden. Nach Einsatz des Ganzen werden fluchtend zu den Stahlrohren 4 an bereits im rohrförmigen Einsatz 2 vorhandenen Öffnungsausschnitten die Einprägungen 24 angebracht und die Enden der Rohre 4 flüssigkeitsdicht von der bei der Montage noch offe-15 nen Wasserseite her verschweisst. 5 The rear sleeve part 6 'is advantageously formed in two parts in the form of an upper and lower half 13, 14, which considerably simplifies the introduction of the heat exchanger 1 into the rear sleeve part 6' composed of it, since the two halves 13, 14 with their through openings 7 io simply put on the ends of the steel tubes 4. After use of the whole, the embossments 24 are applied in alignment with the steel tubes 4 to opening cutouts already present in the tubular insert 2 and the ends of the tubes 4 are welded in a liquid-tight manner from the water side which is still open during assembly.
