Description
<Desc/Clms Page number 1>
Feuerraum-Auskleidung aus feuerfesten Steinen Für die Auskleidung von Feuerräumen ist es oft wünschenswert, die feuerfesten Steine ohne die Verwendung eines Zementes so zusammenzustellen, dass die Fugen möglichst gasdicht sind. Vor allem bei ölbefeuerten Öfen und Kesseln sollten einzelne Steine auswechselbar sein und gleichzeitig sollte die Ausmauerung häufig dazu dienen, die Rauchgase in ganz bestimmter Weise zu leiten, was vollkommen nur mit gasdichten Wänden möglich ist.
Den Gegenstand der vorliegenden Erfindung bildet nun eine Feuerraum-Auskleidung aus rechteckigen oder quadratischen, plattenförmigen Steinen, wobei von den vier schmalen Begrenzungsflächen eines Steines mindestens eine eine Nut aufweist.
Ein Ausführungsbeispiel eines Steines mit rechteckiger Nut, welche um den ganzen Stein herumläuft, veranschaulicht Fig. 1 in Auf- und Seitenriss. Eine beliebige, andere Nutenform ist natürlich auch möglich, zum Beispiel gerundet, quadratisch oder trapezartig.
Fig. 2 veranschaulicht beispielsweise eine aus diesen Steinen aufgebaute Wandung in vertikalem Schnitt. In die Nuten der Steine S wird ein Dichtungsmaterial D eingelegt und zwar mit Vorteil so, dass sich die Steine gegenseitig nicht berühren, weil so durch das Eigengewicht der Steine auf das Dichtungsmaterial stets ein gewisser Druck ausgeübt wird, der die Dichtheit verbessert. Als Dichtungsmaterial wird am besten etwas Weiches oder Elastisches gewählt, wie zum Beispiel ein Asbest-Halbfabrikat oder ein Silikon.
Wegen des besseren Dichtens durch das Eigengewicht der Steine, wird beim Aufbau einer Wand am besten so vorgegangen, dass wie in Fig. 3 angegeben, die horizontalen Dichtungen aus durchgehenden Streifen bestehen, während als vertikale Dich- tungen genau in der Länge eingepasste Stücke verwendet werden. Ein gewisser Abstand auch zwischen horizontal nebeneinander liegenden Steinen ist von Vorteil, weil so beim Aufbau der Wand die vertikalen Dichtungsstreifen gut in die Nuten gepresst werden können. Die Steine können auch in der Vertikalen gegeneinander versetzt angeordnet werden, wie durch Fig. 4 veranschaulicht wird.
Ferner sind auch Dichtungen gemäss Fig. 5, mit kreuzförmigen Dichtungsstücken an den Stosstellen von 4 Steinen möglich; besonders dicht wird eine Wand natürlich sein, wenn Dichtungsstücke gemäss Fig. 3 und Fig. 5 gleichzeitig verwendet werden, wobei die Stärke (Dicke) des Dichtungsmaterials nur je halbe Fugenbreite gross gewählt wird.
Einfachere Ausführungen als die in der Zeichnung dargestellten sind in der Weise möglich, dass nur eine oder zwei Schmalseiten der Steine mit einer Nut versehen werden. Im ersten Fall würde auf eine Dichtung in der Horizontalen oder Vertikalen verzichtet, während im zweiten Fall das Dichtungsmaterial jeweils an der glatten Wandung des benachbarten Steines anliegen würde.

Firebox lining made of refractory bricks For lining fireplaces, it is often desirable to put together the refractory bricks without using cement so that the joints are as gas-tight as possible. Particularly in oil-fired stoves and boilers, individual stones should be exchangeable and at the same time the brickwork should often serve to guide the smoke gases in a very specific way, which is only possible with gas-tight walls.
The subject of the present invention now forms a furnace lining made of rectangular or square, plate-shaped stones, at least one of the four narrow boundary surfaces of a stone having a groove.
An exemplary embodiment of a stone with a rectangular groove which runs around the entire stone is illustrated in FIG. 1 in front and side elevation. Any other groove shape is of course also possible, for example rounded, square or trapezoidal.
Fig. 2 illustrates, for example, a wall built up from these stones in vertical section. A sealing material D is inserted into the grooves of the stones S, advantageously in such a way that the stones do not touch one another, because the weight of the stones themselves always exerts a certain pressure on the sealing material, which improves the tightness. It is best to choose something soft or elastic, such as a semi-finished asbestos product or silicone, as the sealing material.
Because of the better sealing by the dead weight of the stones, when building a wall it is best to proceed in such a way that, as indicated in FIG. 3, the horizontal seals consist of continuous strips, while the vertical seals use pieces that are precisely fitted in length . A certain distance between stones lying horizontally next to one another is advantageous because the vertical sealing strips can then be pressed easily into the grooves when the wall is being built. The stones can also be arranged offset from one another in the vertical, as illustrated by FIG. 4.
Furthermore, seals according to FIG. 5, with cross-shaped sealing pieces at the abutment points of 4 stones, are also possible; A wall will of course be particularly tight if sealing pieces according to FIG. 3 and FIG. 5 are used at the same time, the strength (thickness) of the sealing material being selected to be only large per half the joint width.
Simpler designs than those shown in the drawing are possible in such a way that only one or two narrow sides of the stones are provided with a groove. In the first case, a horizontal or vertical seal would be dispensed with, while in the second case the sealing material would rest against the smooth wall of the adjacent stone.
