Description

Heizkessel für Festbrennstoffe  Boiler for solid fuel
Technisches Gebiet Technical area
Die Erfindung bezieht sich auf einen Heizkessel für Festbrennstoffe, insbesondere aus nachwachsenden Rohstoffen, mit einem zum Verbrennen der Festbrennstoffe vorgesehenen Brennraurh, der eine feuerfeste und gasdichte Wandauskleidung aus mehreren nebeneinander angeordneten Wandsteinen, insbesondere Schamottsteinen, aufweist, von denen wenigstens ein Wandstein mit seinen seitlich anschließenden Wandsteinen Stoßflächen ausbildet, die sich in Richtung des Brennraums keilförmig verjüngen. The invention relates to a boiler for solid fuels, in particular from renewable raw materials, provided with a combustion of solid fuels Brennraurh having a refractory and gas-tight wall lining of several juxtaposed wall stones, especially firebricks, of which at least one wall brick with its laterally adjacent Wall stones forms abutment surfaces, which taper in the direction of the combustion chamber in a wedge shape.
Stand der Technik State of the art
Um eine gasdichte und feuerfeste Wandauskleidung eines Brennraums schaffen zu können, ist es aus dem Stand der Technik bekannt (DE 80 20 292 U1), Wandsteine nebeneinander anzuordnen und bei den Stoßflächen der Wandsteine Dichtungsmittel einzusetzen. Derartige Stoßflächen können auch Schrägkanten für erhöhte Dichtungsflächen aufweisen, sodass bekannte Wandsteine Stoßflächen ausbilden, die sich in Richtung des Brennraums keilförmig verjüngen. Von Nachteil bei einer derartigen feuerfesten Wandauskleidung ist, dass neben dem vergleichsweise hohen konstruktiven Aufwand für das Einbringen der Dichtungsmittel diese aufgrund der Temperaturbelastung einen dauerhaften Abschluss gegenüber einem Gasdurchtritt kaum gewährleisten können. Vergleichsweise niedrige Standzeiten derartiger Brennkammern sind somit in Kauf zu nehmen. Hinzu kommt, dass Schrägkanten bzw. Keilflächen einer genauen Positionierung bedürfen, um ein dichtes Anschließen der Wandsteine zu gewährleisten, sodass derartige feuerfeste Wandauskleidungen vergleichsweise umständlich herstellbar und damit kostenintensiv sind. In order to create a gas-tight and fireproof wall lining a combustion chamber, it is known from the prior art (DE 80 20 292 U1) to arrange wall stones next to each other and to use sealing means in the abutment surfaces of the wall stones. Such abutment surfaces can also have inclined edges for increased sealing surfaces, so that known wall stones form abutment surfaces which taper in the direction of the combustion chamber in a wedge shape. The disadvantage of such a refractory wall lining is that in addition to the relatively high design cost for the introduction of the sealant they can hardly guarantee a permanent conclusion against a gas passage due to the temperature load. Comparatively low service life of such combustion chambers are therefore to be accepted. In addition, oblique edges or wedge surfaces require accurate positioning in order to ensure a tight connection of the wall stones, so that such refractory wall linings are relatively cumbersome to produce and therefore expensive.
Um bessere Strömungsbedingungen für die Verbrennungsgase zu schaffen, ist es bekannt (GB 856 517 A), die den Brennraum begrenzenden Wandsteine parabolisch geformt und nach oben offen auszubilden. Da die Wandsteine in unterschiedlichen Winkeln zueinander stehen, ergeben sich gegen den Brennraum hin verjüngende Keilflächen mit den bereits aufgezeigten Schwierigkeiten hinsichtlich der Abdichtung. Gleiches gilt für eine andere bekannte Brennkammer (AT 504 652 A4), bei der unterhalb einer Bodenplatte der Brennkammer mehrere Abbrandsteine vorgesehen sind, die einen sich in Strömungsrichtung der Verbrennungsgase erweiternden Verlauf aufweisen, oder eine Brennkammer mit einem von Gaskanälen durchzogenen Rost aus feuerfesten Steinen (WO 2006/041391 A1), die in Richtung der Brennkammer kreisförmig-ovale, kegelartige Vorsprünge aufweisen. In order to provide better flow conditions for the combustion gases, it is known (GB 856 517 A) to parabolic the walls bounding the combustion chamber and open at the top. Since the wall stones are at different angles to each other, resulting against the combustion chamber towards tapered wedge surfaces with the already indicated difficulties in terms of sealing. The same applies to another known combustion chamber (AT 504 652 A4), in which a plurality of burnt bricks are provided below a bottom plate of the combustion chamber, which have a widening in the flow direction of the combustion gases course, or a combustion chamber with a traversed by gas ducts rust refractory bricks ( WO 2006/041391 A1), which have circular-oval, conical projections in the direction of the combustion chamber.
Darstellung der Erfindung Presentation of the invention
Die Erfindung hat sich daher die Aufgabe gestellt, ausgehend vom eingangs geschilderten Stand der Technik eine feuerfeste und gasdichte Wandauskleidung für einen Brennraum zu schaffen, die nicht nur eine hohe Standzeit sondern auch vergleichsweise konstruktiv einfach und kostengünstig ist. The invention is therefore based on the object, starting from the above-described prior art to provide a refractory and gas-tight wall lining for a combustion chamber, which is not only a long service life but also comparatively simple and inexpensive.
Die Erfindung löst die gestellte Aufgabe dadurch, dass sich die Stoßflächen zusätzlich in eine zur Richtung des Brennraums andere Richtung, insbesondere in Richtung des Brennraumbodens, keilförmig verjüngen. Verjüngen sich die Stoßflächen zusätzlich in eine zur Richtung des Brennraums andere Richtung, so kann anhand der damit entstehenden zweifachen Keilwirkung des Wandsteins über seine Keilflächen bzw. Stoßflächen ermöglicht werden, dass sich ein besonders gasdichter Anschluss ausbilden kann. Im Gegensatz zum Stand der Technik kann daher auch ohne Dichtungsmittel stets für eine gasdichte Wandauskleidung gesorgt werden, so dass eine hohe Standfestigkeit der Wandauskleidung gewährleistet werden kann. Außerdem kann auch durch die zweifache Keilwirkung des Wandsteins der Konstruktionsaufwand vermindert werden, weil selbst bei Fertigungstoleranzen durch die zweifache Keilform ein passgenauer Anschluss zwischen den Wandsteinen geschaffen werden kann. Die Erfindung zeichnet sich daher nicht nur durch eine gute Standfestigkeit, sondern auch durch eine konstruktive Einfachheit und damit Kostengünstigkeit der Brennkammer aus. Insbesondere kann sich eine besondere zweifache Keilwirkung ergeben, wenn sich die Stoßflächen zusätzlich in Richtung des Brennraumbodens verjüngen. The invention achieves the stated object in that the abutment surfaces additionally taper in a wedge shape in a direction other than the direction of the combustion chamber, in particular in the direction of the combustion chamber floor. If the abutment surfaces additionally taper in a direction that is different from the direction of the combustion chamber, the wedge surfaces or abutment surfaces can be made possible by means of the double wedge effect of the wall stone that forms a particularly gas-tight connection. In contrast to the prior art can therefore always be provided without sealant for a gas-tight wall lining, so that a high stability of the wall lining can be ensured. In addition, the design effort can be reduced by the double wedge effect of the wall stone, because even with manufacturing tolerances can be created by the double wedge shape a perfect fit connection between the wall stones. The invention is therefore characterized not only by a good stability, but also by a constructive simplicity and thus cost-effectiveness of the combustion chamber. In particular, a particular double wedge effect may result if the abutment surfaces additionally taper in the direction of the combustion chamber floor.
Auf konstruktiv einfache Weise besteht die Wandauskleidung aus vier Wandsteinen, wobei zwei gegenüberliegende Wandsteine die keilförmig zulaufenden Stoßflächen ausbilden. In a structurally simple way, the wall lining consists of four wall stones, with two opposite wall stones form the wedge-shaped tapered abutment surfaces.
Um den Brennraum mit Verbrennungsluft versorgen zu können, kann vorgesehen sein, dass wenigstens ein Wandstein Öffnungen für die Luftzufuhr aufweist. In order to supply the combustion chamber with combustion air, it can be provided that at least one wall brick has openings for the air supply.
Ist wenigstens zwischen den Wandsteinen auf der den Brennraum abgewandten Seite eine elastische Dichtung vorgesehen, so kann nicht nur ein fester Sitz der Wandsteine im Verbund sondern es kann auch die Wandauskleidung gegenüber einem Gasdurchtritt an den Anschlussstellen verbessert werden. Zu diesem Zweck kann vorgesehen sein, dass im Bereich der Anschlussstellen zwischen den Wandsteinen auf der dem Brennraum abgewandten Seite eine elastische Dichtung vorgesehen ist. Kurze Beschreibung der Zeichnung If an elastic seal is provided at least between the wall stones on the side facing away from the combustion chamber, then not only can the wall stones be firmly seated in the composite, but the wall lining can also be improved compared to a gas passage at the connection points. For this purpose it can be provided that in the region of the connection points between the wall stones on the side facing away from the combustion chamber, an elastic seal is provided.

Weg zur Ausführung der Erfindung Way to carry out the invention
Die in Fig. 1 beispielsweise dargestellte feuerfeste Wandauskleidung 1 einer nach Fig. 4 dargestellten Brennkammer 2 eines Heizkessels 3 begrenzt einen Brennraum 4 zum Verbrennen von Festbrennstoffen 5. Die Wandauskleidung 1 besteht aus mehreren Wandsteinen 6, 7, 8 und 9, die nebeneinander angeordnet sind, damit Rauchgase der Brennkammer 2 die Wandauskleidung 1 nicht durchdringen können. Als Wandsteine 6, 7, 8 und 9 können auch Schamottsteine verwendet werden. Die Wandsteine 6, 7 und 9 bilden zwischen sich Stoßflächen 10 und 11 , die keilförmig in Richtung 12 des Brennraums 4 zulaufend, was der Fig. 2 entnommen werden kann. Die die Stoßflächen 10 und 11 aufnehmenden Ebenen 10', 11 ' bilden so einen in Richtung 12 des Brennraums 4 gerichteten Keil. Um nun für einen besonders dichten Anschluss zwischen den Wandsteinen 6, 7 und 9 zu sorgen, verjüngen sich die keilförmig in Richtung 12 des Brennraums zulaufenden Stoßflächen 10 und 11 zusätzlich in eine zur Richtung 12 des Brennraums 4 andere Richtung 13 keilförmig, wodurch sich eine doppelte Keilwirkung einstellen kann, was der Fig. 3 besser entnommen werden kann. Die entsprechenden Ebenen 10' und 11' der Stoßflächen 10 und 11 schneiden sich daher in zwei zueinander geneigten Schnittgeraden 12' und 13' der beiden Keile. Durch die derart geneigt gewählten Stoßflächen 10 und 11 ergibt sich neben einer besonderen Gasdichtheit auch ein vergleichsweise einfacher Zusammenbau der Wandauskleidung 1 , weil nämlich nach einem Einfügen der Wandsteine 6 und 7 die restlichen Wandsteine 8 und 9 mit vergleichsweise geringem Kraftaufwand von oben in die Wandauskleidung 1 eingesetzt werden können, insbesondere dann, wenn sich die Stoßflächen 10, 11 in Richtung 13 des Brennraumbodens 4' keilförmig verjüngen. The illustrated in Fig. 1, for example, refractory wall lining 1 of Fig. 4 illustrated combustion chamber 2 of a boiler 3 defines a combustion chamber 4 for burning solid fuel 5. The wall lining 1 consists of several wall stones 6, 7, 8 and 9, which are arranged side by side so that flue gases of the combustion chamber 2, the wall lining 1 can not penetrate. As wall stones 6, 7, 8 and 9 and fireclay bricks can be used. The wall stones 6, 7 and 9 form between them abutting surfaces 10 and 11, the tapered in the direction 12 of the combustion chamber 4, which can be seen in FIG. 2. The abutment surfaces 10 and 11 receiving planes 10 ', 11' thus form a directed in the direction 12 of the combustion chamber 4 wedge. In order to ensure a particularly tight connection between the wall stones 6, 7 and 9, tapering in the direction of 12 of the combustion chamber tapered surfaces 10 and 11 taper in addition to the direction 12 of the combustion chamber 4 other direction 13 wedge-shaped, resulting in a double Can adjust wedge effect, which can be better taken from Fig. 3. The corresponding planes 10 'and 11' of the abutment surfaces 10 and 11 therefore intersect in two mutually inclined cutting lines 12 'and 13' of the two wedges. By so inclined selected abutment surfaces 10th and 11 results in addition to a special gas-tightness and a comparatively simple assembly of the wall lining 1, namely, that after inserting the wall stones 6 and 7, the remaining wall stones 8 and 9 can be used with relatively little effort from above in the wall lining 1, in particular, when the abutment surfaces 10, 11 taper in a wedge shape in the direction 13 of the combustion chamber bottom 4 '.
Zwei gegenüberliegende Wandsteine 8 und 9 der vier Wandsteine 6, 7, 8 und 9 sind formgleich ausgebildet, und weisen je keilförmig zulaufende Stoßflächen 10, 11 bzw. 14 und 15 auf. Two opposite wall stones 8 and 9 of the four wall stones 6, 7, 8 and 9 are of identical shape, and each have wedge-shaped tapered abutting surfaces 10, 11 and 14 and 15 respectively.
Dem Brennraum 4 wird über eine Luftzufuhr 16, 17 Brennluft 18 zugeführt, was der Fig. 4 besser entnommen werden kann. Die Luftzufuhr 16, auch unter Primärluftzufuhr bekannt, erfolgt über den Aschenraum 19 unterhalb des Brennraums 4, wobei die Luftzufuhr 17, auch unter Sekundärluftzufuhr bekannt, über Öffnungen 20 in den Wandsteinen 6, 7, 8 und 9 erfolgt. Zu diesem Zweck ist ein Luftkanal 21 vorgesehen. The combustion chamber 4 is supplied via an air supply 16, 17 combustion air 18, which can be better taken from Fig. 4. The air supply 16, also known under primary air supply, via the ash chamber 19 below the combustion chamber 4, wherein the air supply 17, also known under secondary air supply, via openings 20 in the wall stones 6, 7, 8 and 9 takes place. For this purpose, an air duct 21 is provided.
Um für einen vorteilhaften Sitz der Wandsteine 6, 7, 8 und 9 sorgen zu können, ist zwischen den Wandsteinen 6, 7, 8 und 9 auf der dem Brennraum 4 abgewandten Seite eine elastische Dichtung 23 vorgesehen, die auch im Bereich der Anschlussstellen 24 der Wandsteine 6, 7, 8 und 9 für einen dichten Ab- schluss des Brennraums 4 gegenüber der Brennkammerwand 22 sorgt. In order to provide for an advantageous fit of the wall stones 6, 7, 8 and 9, an elastic seal 23 is provided between the wall stones 6, 7, 8 and 9 on the combustion chamber 4 side facing away, which also in the area of the connection points 24 of Wall stones 6, 7, 8 and 9 ensures a tight seal of the combustion chamber 4 with respect to the combustion chamber wall 22.
