   Bei Feuerungsanlagen mit Vorschub des Brennstoffes durch einen   gusseisernen   Quer-   balken   sind die für die Besichtigung der Feuerung und für einen erforderlich werdenden Eingriff in dieselbe dienenden verschliessbaren Öffnungen in dem Beschickungsbalken selbst angeordnet Gemäss   der Erfindung   wird dagegen die Öffnung an der Vorderseite des Zuführungstrichters T angeordnet ; sie wird für gewöhnlich durch eine auf und ab verschiebbare Platte P (Fig. i und 2) verschlossen. Die Auf-und Abbewegung dieser Verschlussplatte kann in beliebiger Weise bewerkstelligt werden. Bei der in der Zeichnung gewählten Anordnung erfolgt der Antrieb der   Verschlussplatte mittels   Kurbel, Schnecke, Schneckenrad, Zahnrad und Zahnstange. 



   Statt einer einzigen über die ganze Breite des Rostes sich erstreckenden Öffnung können auch mehrere   nebeneinander liegende Öffnungen   angeordnet werden ; statt einer einzigen Verschlussplatte können mehrere in Verwendung kommen. 



   Die beim Heben der   Verschlussplatte   frei werdende Öffnung gestattet infolge ihrer Höhenlage über der Brennbahn und infolge ihrer Grösse eine bequeme Beobachtung der ganzen Rostfläche sowie einen leichten Eingriff auf jeden Punkt derselben, insbesondere ein rasches Herausreissen der Feuerung im Notfalle. 



   PATENT ANSPRÜCHE : i.   Treppenrostfeuerung   mit mechanischer Beschickung, gekennzeichnet durch einen nicht gekühlten, gusseisernen Querbalken (B) für die Armierung der   Feuerungsvorderwand.   der durch einen auswechselbaren, vorteilhaft aus mehreren nebeneinander angeordneten Teilen bestehenden eisernen Schutzbalken (C), sowie durch eine vorteilhaft aus einzelnen Teilen bestehende aus-   wechselhare   Vorlage (D) aus feuerfestem Material geschützt ist.

   In the case of firing systems with the fuel being fed through a cast-iron crossbeam, the closable openings for inspecting the firing and for any intervention in the same are arranged in the loading bar itself. According to the invention, however, the opening is arranged on the front of the feed hopper T; it is usually closed by a plate P which can be slid up and down (FIGS. i and 2). This closure plate can be moved up and down in any desired manner. In the arrangement chosen in the drawing, the closure plate is driven by means of a crank, worm, worm wheel, toothed wheel and rack.



   Instead of a single opening extending over the entire width of the grate, several openings lying next to one another can also be arranged; Instead of a single closure plate, several can be used.



   The opening that becomes free when the closure plate is lifted allows, due to its height above the focal path and due to its size, a comfortable observation of the entire grate surface and easy access to every point of the same, in particular a quick tearing out of the furnace in an emergency.



   PATENT CLAIMS: i. Step grate firing with mechanical charging, characterized by a non-cooled, cast iron crossbeam (B) for reinforcing the front wall of the furnace. which is protected by an exchangeable iron protective bar (C), which advantageously consists of several parts arranged next to one another, as well as an exchangeable template (D) made of refractory material, which advantageously consists of individual parts.
