PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung bildet eine Umrahmung aus Hohlwänden für die Unterfeuerung an Niederdruckdampf- und Warmwasserheizkesseln, in welchen Wasser umläuft und dann vorgewärmt dem Kessel zugeführt wird.The present invention forms a frame made of cavity walls for the Underfiring on low-pressure steam and hot water boilers, in which water circulates and then preheated the boiler is fed.
In diese Umrahmung ist ein aus einzelnen Stäben bestehender Hohlrost so eingesetzt, dafs an die beiden äufsersten Roststäbe je eine Seitenwand der Umrahmung sich anschliefst bezw. damit verbunden ist, wobei durchgehende Bolzen den Hohlrost und die Seitenwände zusammenhalten. Diese Seitenwande sind aufserdem mit einer Vorder- und Hinterwand so verbunden; dafs das Wasser gleichmäfsig durch alle Roststäbe und die mit denselben verbundenen Wände umzulaufen vermag.A hollow grating consisting of individual rods is inserted into this frame in such a way that a side wall of the frame adjoins the two outermost grate bars respectively is connected to it, with continuous bolts the hollow grate and the side walls stick together. These side walls also have a front and rear wall so connected; that the water evenly through all grate bars and those with able to run around the same connected walls.

Fig. 5 einen waagerechten Schnitt durch die Roststäbe in gröfserem Maafsstabe undFig. 5 shows a horizontal section through the grate bars on a larger scale and
Fig. 6 einen solchen Schnitt durch. den unteren Theil der Feuerung.Fig. 6 through such a section. the lower part of the furnace.
Die Unterfeuerung befindet sich zwischen den Hohlwänden W\ W% W3 und W\ welche vermittelst durchgehender Bolzen zusammengehalten werden und von denen W4 die Feuerbrücke bildet.The underfiring is located between the hollow walls W \ W% W 3 and W \ which are held together by means of through bolts and of which W 4 forms the fire bridge.
An die Hohlwand W1 und W'2 schliefst sich der aus einzelnen Stäben gebildete Rost R an; er ist ebenfalls hohl und seine Stäbe besitzen an den Enden seitliche Oeffnungen, durch die sie mit denen der beiden Hohlwände verbunden sind. Durch diese Oeffnungen und Hohlwände sind Bolzen gezogen, die an den Enden Muttern tragen behufs festen Aneinanderziehens der Roststäbe R an die beiden Seitenwände W1 und W'2. An den Verbindungsstellen der Hohlwände und an denen der Roststäbe sind kleine abdichtende Rohrstücke eingebracht. The grate R formed from individual bars adjoins the hollow wall W 1 and W '2; it is also hollow and its rods have lateral openings at the ends through which they are connected to those of the two hollow walls. Bolts are pulled through these openings and hollow walls, which have nuts at the ends for the purpose of firmly tightening the grate bars R on the two side walls W 1 and W ' 2 . At the connection points of the cavity walls and where the grate bars are located, small, sealing pieces of pipe are inserted.
Auf diese Weise ist der ganze r Feuerraum unten und an den Seiten von gekühlten Wandungen umgeben, so dafs Chamottemauerwerk, an welches leicht Schlacken anbacken, in Wegfall kommt.In this way the whole r combustion chamber is surrounded on the sides and bottom of the cooled walls; so that Chamottemauerwerk to which slightly caking slags takes elimination.
