Description

Feuerung für 1~'lännmröhrkessel mit einer oberhalb -des Rostes angeordneten haubenartigen . Brennstoffentgasungskammer Die Erfindung erstreckt sich auf Feuerungen für Flammrohrkessel, bei welchen durch Ausbuchtungen der inneren Flammrohrwand über dem Rost eine mittlere haubenförmige Brennstoffentgasungskammer und seitlich davon Abzugskanäle für die Heizgase gebildet werden. Als Abschluß der Entgasungskammer ist hier hinter dem Rost eine Querwand eingebaut- die die in der Kammer erzeugten Schwelgase zwingt, durch die seitlichen Abzugskanäle und den glühenden Brennstoff hin.-wegzustreichen. Da die Abschlußwand den Abzug der Schwelgase auf die seitlichen schmalen Durchgangskanäle beschränkt, wird der Brennstoff an der Abschlußwand nur unvollkommen entgast und gezündet werden. Infolgedessen werden die Schwelgase hier urverbrannt entweichen können.Firing for 1 ~ 'lännmröhrkessel with one above the grate hood-like. Fuel degassing chamber The invention extends to furnaces for flame tube boilers, in which the inner flame tube wall protrudes through bulges the grate a central hood-shaped fuel degassing chamber and to the side of it Flue ducts for the hot gases are formed. As a conclusion to the degassing chamber a transverse wall is installed behind the grate - the one created in the chamber Smoldering gases are forced through the side exhaust ducts and the glowing fuel to cross out. Since the end wall allows the carbonization gases to be drawn off to the side limited by narrow passages, the fuel is only attached to the end wall be imperfectly degassed and ignited. As a result, the smoldering gases are here can escape completely burned.

Zur Vermeidung dieses Nachteils sind nun bei der den Gegenstand der Erfindung bildenden Feuerung für Flammrohrkessel die seitlichen Begrenzungsrippen der Entgasungskammer an ihrem hinteren Ende durch eine gleichartige, in der Querrichtung des Flammrohres sich erstreckende Ausbuchtung, die zwischen sich und der Feuerbrücke des Rostes einen Abzugskanal für die Heizgase frei läßt, miteinander verbunden. Für den Abzug der Schwelgase ist also noch ein hinterer Abzugskanal geschaffen. Da dieser durch glühenden Brennstoff abgeschlossen ist, so müssen die durch ihn hindurchstreichenden Schwelgase restlos zur Verbrennung gelangen.To avoid this disadvantage are now the subject of Invention forming furnace for flame tube boilers the lateral boundary ribs the degassing chamber at its rear end by a similar one in the transverse direction of the flame tube extending bulge between itself and the fire bridge of the grate leaves a duct for the hot gases free, connected to each other. A rear exhaust duct is also created for the extraction of the smoldering gases. Since this is closed off by glowing fuel, they must go through it the smoldering gases passing through reach combustion.

Auf der Zeichnung ist eine Ausführungsform der neuen Flammrohrfeuerung dargestellt, und zwar zeigt Abb. z einen senkrechten Längsschnitt durch den Flammrohrkessel und Abb. z einen Querschnitt nach Linie A-B der Abb. z.The drawing shows an embodiment of the new flame tube furnace shown, namely Fig. z shows a vertical longitudinal section through the flame tube boiler and Fig. z shows a cross section along line A-B of Fig. z.

Oberhalb des Rosteinbaues e ist die Innenwand b des Flammrohrkessels a in der Längsrichtung nach bekannter Weise mit zwei rippenartigen Ausbuchtungen d versehen, durch welche in der Mitte über dem Rost leine Brennstoff- und Vergasungskammer c und zu beiden Seiten Gasabzugskanäle g abgegrenzt werden. Gemäß, der Erfindung sind nun die seitlichen Begrenzungsrippen d der Entgasungskammer an ihrem hinteren Ende durch gleichartige, in der Querrichtung des Flammrohres sich erstreckende Ausbuchtungen/ und h miteinander verbunden. Hierdurch wird eine hintere, die Entgasungskammer begrenzende Abschlußwand gebildet, die zwischen sich und der Feuerbrücke des Rostes auch leinen hinteren Abzugskanal g für die Heizgase frei läßt.Above the grate installation e, the inner wall b of the fire tube boiler a is provided in the longitudinal direction in a known manner with two rib-like bulges d, through which in the middle above the grate a leash fuel and gasification chamber c and gas discharge ducts g are delimited. According to the invention, the lateral delimiting ribs d of the degassing chamber are now connected to one another at their rear end by similar bulges / and h extending in the transverse direction of the flame tube. As a result, a rear end wall delimiting the degassing chamber is formed, which also leaves a rear exhaust duct g free for the hot gases between itself and the fire bridge of the grate.

Wird nun in die :durch-die wulstartig nieder-gebogene Flammrohrinnenwand begrenzte haubenartige Entgasungskammer c Brennstoff eingebracht und in Brand gesetzt, so böscht er sich in den Abzugskanälen ab und verschließt sie mit seinen in heller Glut stehenden Teilen. Beim Vergasen des Brennstoffes in der Kammer müssen alle Gase durch die glühende Brennstoffschicht hindurchströmen und restlos verbrennen.If fuel is now introduced into the hood-like degassing chamber c, which is delimited by the bead-like, downwardly curved flame tube inner wall and is set on fire, it empties into the flue ducts and closes them with its brightly glowing parts. When gasifying the fuel in the chamber, all gases must flow through the glowing fuel layer and burn completely.
