Abstract

The invention relates to a boiler equipped with a downstream burner, with waste gas temperature regulation, which consists of a water-bearing housing (1) with a combustion chamber (2) which is surrounded by an annular heating gas flue (5) which leads to the smoke gas take-off and is divided into individual flues (4) by a large number of longitudinal ribs (3). In the region on the take-off side, there is arranged a sealing flap (6) which is adjustable depending upon the waste gas temperature and covers one or more individual flues (4). According to the invention, such a boiler equipped with a downstream burner is designed in such a manner that there is arranged in front of the sealing flap (6) in the heating gas flue (5) a longitudinal rib-free smoke gas duct (7) with a width which corresponds at least to the width of three individual flues (4). The width and cross-sectional shape of the sealing flap (6) corresponds at the same time to the cross-section of the smoke gas duct (7). The flap (6) is provided with a bimetallic regulator (8). The smoke gas duct (7) is arranged below the mouth (12) of the waste gas connection piece (9) and the bimetallic regulator (8) of lever-like design is fastened with its flap-free end (13) in the waste gas connection piece (9). <IMAGE>

Description

Die Erfindung betrifft einen Sturzbrennerheizkessel mit Ab­gastemperaturregelung gemäß Oberbetriff des Hauptanspruches.The invention relates to a lint burner boiler with exhaust gas temperature control according to the preamble of the main claim.

Derartige Heizkessel sind allgemein bekannt und in Benutzung, so daß es diesbezüglich keines besonderen druckschriftlichen Nachweises bedarf. Um Heizenergie zu sparen, aber auch um die Brennerlaufzeiten zu verkürzen, werden Öl- oder Gasgebläse­brenner verstärkt eingesetzt, die mit abgestufter oder sog. modulierender Leistung betrieben werden können, um die Lei­stung der Brenner in Zeiten geringeren Wärmebedarfs entspre­chend anpassen zu können. Dabei ergibt sich aber das Problem, daß die Abgastemperatur der Kessel sinkt und der Schornstein nicht ausreichend mit Wärme beaufschlagt wird, was zu einer Kondensation der Verbrennungsgase im Schornstein führen kann, die es aber zu verhindern gilt, da sonst der Schornstein durch­feuchtet. In diesem Zusammenhang sind schon die verschiedensten Lösungen vorgeschlagen worden, bspw. auch in Form von tempera­turabhängig regelbaren Klappen, die mit Gestängen, Stellmotoren, aber auch Bimetall-Elementen verstellbar sind.
Derartige Klappenregelungen arbeiten mehr oder weniger zufrie­denstellend. "Mehr oder weniger" deshalb, weil man kesselseitig keine entsprechenden Maßnahmen getroffen hat, d.h. auf die wirksame Wärmeübertragungsfläche, die zwangsläufig Auswirkung auf die Höhe der Abgastemperatur hat, hat man keinen Einfluß genommen.Such boilers are generally known and in use, so that no special printed evidence is required in this regard. In order to save heating energy, but also to shorten the burner runtimes, oil or gas fan burners are increasingly being used, which can be operated with graded or so-called modulating output in order to be able to adjust the burner output accordingly in times of lower heat requirements. The problem arises, however, that the flue gas temperature of the boiler drops and the chimney is not subjected to sufficient heat, which can lead to condensation of the combustion gases in the chimney, which must be prevented, however, since otherwise the chimney will become damp. In this context, a wide variety of solutions have already been proposed, for example also in the form of flaps which can be regulated as a function of temperature and which can be adjusted using rods, servomotors and also bimetal elements.
Such flap controls work more or less satisfactorily. "More or less" because no appropriate measures have been taken on the boiler side, ie no influence has been taken on the effective heat transfer surface, which inevitably has an effect on the flue gas temperature.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, einen Kessel der eingangs genannten Art dahingehend zu verbessern, daß mit einfachen Mitteln und Maßnahmen eine optimalere Abgastempera­turregelung bewirkt werden kann.The invention is therefore based on the object to improve a boiler of the type mentioned in such a way that a more optimal exhaust gas temperature control can be achieved with simple means and measures.

Diese Aufgabe ist mit einem Heizkessel der eingangs genannten Art nach der Erfindung durch die im Kennzeichen des Hauptan­spruches angeführten Merkmale gelöst. Vorteilhafte Weiterbil­dungen ergeben sich nach den Unteransprüchen.This object is achieved with a boiler of the type mentioned according to the invention by the features stated in the characterizing part of the main claim. Advantageous further developments result from the subclaims.

Durch diese erfindungsgemäße Ausbildung ist dafür gesorgt, daß in Zeiten geringeren Wärmebedarfs, also niedrig eingestellter Brennerleistung, die Heiz- bzw. Rauchgase in hohem Maße durch den bei geöffneter Verschlußklappe freigestellten Rauchgaskanal abströmen können, wobei aber dafür gesorgt ist, daß in diesem Rauchgaskanal sowohl der Widerstand als auch die Wärmeübertra­gungsfläche ganz wesentlich reduziert sind, so daß die durch­strömenden Heizgase dort nur noch wenig Wärme abgeben können und mit relativ hohem Temperaturniveau in den Abzug gelangen. Von der Kesselkonstruktion her ist dies einfach dadurch zu er­reichen, daß man im Bereich des Rauchgaskanales dort einfach einige der Längsrippen wegläßt. Die Breite und Querschnittsform der Verschlußklappe ist dem Querschnitt des Rauchgaskanales an­gepaßt, und die Klappe sitzt dabei abzugsseitig hinter dem Rauchgaskanal am dort angeordneten Bimetall-Regler und kann deshalb, da in einem relativ temperaturniedrigen Bereich ange­ordnet, aus einem entsprechend dünnen Blechsegment mit relativ geringem Gewicht ausgebildet sein, das problemlos von einem an sich bekannten Bimetall-Regler bewegt werden kann. Durch die neuartige Ausbildung geht zwar durch den rippenfrei ausgebilde­ten Rauchgaskanal Heizfläche verloren, andererseits muß aber keine zusätzliche Heizfläche an anderer Stelle vorgesehen wer­den, weil bei geschlossener Klappe die Verbrennungsgase durch die anderen, normal bemessenen Heizgaszüge abströmen, und zwar mit höherem Strömungswiderstand und höherer Geschwindigkeit, wodurch aber der Wärmeübergang an diesen Heizflächen erhöht wird.This inventive design ensures that in times of lower heat requirements, i.e. low burner output, the heating or flue gases can flow out to a large extent through the flue gas duct exposed when the flap is open, but care is taken to ensure that both the flue gas duct and the flue gas duct Resistance and the heat transfer area are significantly reduced, so that the heating gases flowing through there can only emit little heat and get into the fume cupboard at a relatively high temperature level. From the boiler design, this can be achieved simply by simply omitting some of the longitudinal ribs in the area of the flue gas duct. The width and cross-sectional shape of the closure flap is adapted to the cross-section of the flue gas duct, and the flap is located on the exhaust side behind the flue gas duct on the bimetal controller arranged there and, because it is arranged in a relatively low-temperature range, can be formed from a correspondingly thin sheet metal segment with a relatively low weight be that can be easily moved by a known bimetal controller. The novel design means that the heating surface is lost due to the rib-free flue gas duct, but on the other hand no additional heating surface has to be provided because the flue gas flows out through the other, normally dimensioned heating gas flues when the flap is closed, with a higher flow resistance and higher speed. but which increases the heat transfer on these heating surfaces.

Für einen Sturzbrennerkessel der hier vorliegenden Art, bei dem also der Abgasstutzen seitlich neben einer ringförmig den Brenneranschlußbereich umgebenden Sammelkammer angesetzt ist, ist dabei wesentlich, daß der von Längsrippen freige­stellte Rauchgaskanal unter der Einmündung des Abgasstutzens angeordnet und der hebelartig ausgebildete Bimetall-Regler mit seinem freien Ende im Abgasstutzen befestigt ist. Diesbezüglich besteht eine vorteilhafte Weiterbildung darin, daß die Einmün­dung des Abgasstutzens im Querschnitt rechteckig ausgebildet und mit ihrer großen Achse quer zur Längsachse des Kessels an­geordnet ist. Dadurch ist der relativ breite Abströmquerschnitt des Rauchgaskanales besser erfaßbar. Zur Verbesserung der Ver­teilung der Abgase über dem Abzugsquerschnitt im Bereich des Ab­gasstutzens ist vorteilhaft der untere Begrenzungsrand der Ein­mündung schießschartenartig ausgebildet.For a lintel burner boiler of the present type, in which the flue gas connection is positioned laterally next to an annular collection chamber surrounding the burner connection area, it is essential that the flue gas duct, which is free from longitudinal ribs, is arranged under the mouth of the flue gas connection and the lever-like bimetal regulator with its free one End is fixed in the exhaust pipe. In this regard, an advantageous development is that the mouth of the flue gas outlet is rectangular in cross-section and is arranged with its large axis transverse to the longitudinal axis of the boiler. As a result, the relatively wide outflow cross section of the flue gas duct can be better detected. In order to improve the distribution of the exhaust gases over the exhaust cross-section in the area of the exhaust pipe, the lower boundary edge of the junction is advantageously designed in the manner of a loop.

Der erfindungsgemäße Sturzbrennerheizkessel wird nachfolgend anhand der zeichnerischen Darstellung eines Ausführungsbeispie­les näher erläutert.The lint burner boiler according to the invention is explained in more detail below with reference to the drawing of an exemplary embodiment.

Es zeigt

  • Fig. 1 einen Längsschnitt durch einen Sturzbrennerheizkessel;
  • Fig. 2 schematisch eine Ansicht des Sturbrennerheizkessels von der Abzugsseite her gesehen und
  • Fig. 3 einen Querschnitt durch den Sturzbrennerheizkessel ge­mäß Fig. 1, 2 etwa im Bereich der Verschlußklappenan­ordnung.
It shows
  • 1 shows a longitudinal section through a lint burner boiler.
  • Fig. 2 schematically seen a view of the Sturbrennerheizkessel from the trigger side and
  • Fig. 3 shows a cross section through the lint burner boiler according to Fig. 1, 2 approximately in the region of the flap arrangement.

Der Sturzbrennerheizkessel besteht aus einem wasserführenden Gehäuse 1 mit einer Brennkammer 2, die von einem ringförmigen, zum Rauchgasabzug führenden, durch eine Vielzahl von Längsrip­pen 3 in Einzelzüge 4 gegliederten Heizgaszug 5 umgeben ist, wo­bei im abzugsseitigen Bereich eine abgasgemperaturabhängig ver­ stellbare Verschlußklappe 6 angeordnet ist. Insoweit sind derartige Kessel im Prinzip bekannt. "Im Prinzip" deshalb, weil derartige Abgastemperaturregelungen, soweit bekannt, ausschließlich an Heizkesseln mit horizontal orientierter Längsachse verwendet werden. Wesentlich ist nun, daß vor der Verschlußklappe 6 im Heizgaszug 5 ein längsrippenfreier Rauch­gaskanal 7 mit einer Breite angeordnet bzw. vorgesehen ist,die mindestens der Breite dreier Einzelzüge 4 entspricht, daß fer­ner die Breite und die Querschnittsform der Verschlußklappe dem Querschnitt des Rauchgaskanales 7 entspricht und daß schließlich die Klappe 6 an einem abzugsseitig hinter dem Rauchgaskanal 7 angeordneten Bimetall-Regler 8 angeordnet ist.The lint burner boiler consists of a water-bearing housing 1 with a combustion chamber 2, which is surrounded by a ring-shaped, leading to the flue gas outlet, by a plurality of longitudinal ribs 3 divided into individual lines 4 heating gas line 5, with a flue gas temperature-dependent ver in the area on the flue side adjustable shutter 6 is arranged. In this respect, such boilers are known in principle. "In principle" because such exhaust gas temperature controls, as far as is known, are only used on boilers with a horizontally oriented longitudinal axis. It is now essential that a flue gas duct 7 free of longitudinal ribs is arranged or provided in front of the flap 6 in the heating gas flue 5 with a width which corresponds at least to the width of three individual flues 4, that the width and cross-sectional shape of the flap corresponds to the cross section of the flue gas duct 7 and that finally the flap 6 is arranged on a bimetallic regulator 8 arranged behind the flue gas duct 7.

Beim dargestellten Ausführungsbeispiel des Sturzbrennerkes­sels befindet sich der Gasabzugsstutzen 9 seitlich neben einer ringförmig den Brenneranschlußbereich 10 umgebenden Sammel­kammer 11. Hierbei ist der Rauchgaskanal 7 unter der Einmün­dung 12 des Abgasstutzens 9 angeordnet, und der hebelartig ausgebildete Bimetall-Regler 8 mit seinem klappenfreien Ende 13 im Abgasstutzen 9 befestigt. Wie insbesondere aus Fig. 2 ersichtlich, ist dabei die Einmündung 12 des Abgasstutzens 9 im Querschnitt rechteckig ausgebildet und mit ihrer großen Achse 14 quer zur Längsachse 15 des Kessels angeordnet. Die Wand des Abgasstutzens 9 ist dabei so gestaltet, wie eben­falls ohne weiteres aus Fig. 2 erkennbar, daß sich schorn­steinseitig ein kreisförmiger Querschnitt des Abgasstutzens 9 ergibt. Um eine gute Abgasverteilung der bei geöffneter Ver­schlußklappe 6 bevorzugt durch den Rauchgaskanal 7 abströmen­den Verbrennungsgase über den gesamten Abzugsquerschnitt zu erreichen, ist, wie ebenfalls aus Fig. 2 ersichtlich, der un­tere Begrenzungsrand in der Einmündung 12 vorteilhaft in Form von Schießscharten 17 ausgebildet.In the illustrated embodiment of the lint burner boiler, the gas discharge pipe 9 is located on the side next to a collection chamber 11 which surrounds the burner connection area 10 in a ring 9 attached. As can be seen in particular from FIG. 2, the mouth 12 of the flue gas connector 9 is rectangular in cross section and is arranged with its large axis 14 transversely to the longitudinal axis 15 of the boiler. The wall of the flue gas connector 9 is designed in such a way, as can also be readily seen from FIG. 2, that there is a circular cross section of the flue gas connector 9 on the chimney side. In order to achieve a good exhaust gas distribution of the combustion gases flowing through the flue gas duct 7 when the flap 6 is open, the lower boundary edge in the mouth 12 is advantageously formed in the form of embrasures 17, as can also be seen in FIG. 2.
