LICHESLICHES
PATENTAMT.PATENT OFFICE.
: Auf beiliegender Zeichnung ist die Erfindung, bei einer Dampfkesselfeuerung in Anwendung gebracht, dargestellt. Die sich im Feuerraum A bildenden Feuergase umspülen die untere Fläche des Dampfkessels, durchstreichen, nach vorn gehend, die Siederöhren, vertheilen sich alsdann, wieder nach rückwärts gehend, in die beiden Seitenzüge und gelangen, stark abgekühlt, in die zu beiden Seiten des Aschenfalles liegenden Kanäle C, welche durch die Schlitze α mit dem Äschenfall in Verbindung stehen. Durch diese Schlitze α gelangen die Feuergase in den durch Sandverschlafs hermetisch gegen aufsen abgeschlossenen Aschenfall. In diesem verhältnifsmäfsig grofsen Raum vermindert sich die Zuggeschwindigkeit bedeutend, und es soll nun eine Scheidung der Feuerluft in der Weise stattfinden, dafs ein Theil derselben durch den Kanal D in den Kamin abgeführt wird, während der andere Theil durch den Rost wieder in deii-JFeuerraum zurückgesaugt wird.: In the accompanying drawing, the invention is shown in a steam boiler application. The flue gases that form in furnace A wash around the lower surface of the steam boiler, pass through the boiler tubes, going forward, then distribute, going backwards again, into the two side passages and, greatly cooled, get into the two sides of the ash fall Channels C, which are connected to the grayling fall through the slits α. Through these slots α , the fire gases get into the ash fall, which is hermetically sealed from the outside by means of sand sleepers. In this comparatively large space the draft is considerably reduced, and the fire air is now to be separated in such a way that part of it is discharged through duct D into the chimney, while the other part through the grate back into the combustion chamber is sucked back.
Die Zuführung der Verbrennungsluft erfolgt durch den ringförmig um den Feuerraum angeordneten Kanal a, welcher durch Düsen β und ß1 oberhalb und unterhalb des Rostes mit dem Feuerraum A in Verbindung steht. Der nach oben strömende Theil der aus D kommenden Feuerluft mischt sich mit der aus den Düsen ß1 ausströmenden frischen Luft und gelangt durch den Rost in den Feuerraum A, wo die noch unverbrannt gebliebenen Gase nun vollständig verbrannt werden sollen.The combustion air is supplied through channel a, which is arranged in a ring around the combustion chamber and communicates with combustion chamber A through nozzles β and β 1 above and below the grate. The upwardly flowing part of the fire air coming from D mixes with the fresh air flowing out of the nozzles ß 1 and passes through the grate into the combustion chamber A, where the still unburned gases are now to be completely burned.
