Description

Dampfkesselfeuerung aus Wanderrost und diesem vorgeschalteten Treppenrost. Die Erfindung betrifft eine Feuerungsanlage, insbesondere für Dampfkessel, die aus einem Wanderrost und einem diesem vorgeschalteten Treppenrost besteht. Die Erfindung besteht darin, daß die Rostgase der unter einem Großraumkessel mit unteren von Heizrohren durchsetzten Siedern eingebauten Feuerungsanlage nach Abgabe ihrer Hauptwärme an den Dampfkessel wieder auf den Wanderrost zurückgeleitet werden und dann durch die Heizrohre der Sieder abziehen.Steam boiler firing from a traveling grate and this upstream step grate. The invention relates to a firing system, in particular for steam boilers from a traveling grate and a step grating upstream of this. The invention consists in the fact that the rust gases of the under a large boiler with lower of heating pipes interspersed boilers built-in combustion system after releasing their main heat the steam boiler can be returned to the traveling grate and then through the Pull off the heating pipes of the boilers.

In der Zeichnung ist eine als Beispiel dienende Ausführungsform der Erfindung im Schnitt dargestellt.In the drawing, an exemplary embodiment is shown in FIG Invention shown in section.

Unterhalb eines Dampfkessels a ist ein Treppenrost b und ein Wanderrost c derart zueinander angeordnet, daß der von oben auf den Treppenrost geschüttete Brennstoff auf diesem nach und nach zur Verbrennung gelangt. Die unten auf den Wanderrost c fallenden, noch glühenden Brennstoff- und Aschereste werden von dem Wanderrost c allmählich nach dem Aschenausfall d befördert. Die Verbrennnungsgase ziehen von dem Treppenrost b aus unter Beheizung des Dampfkessels a um Zwischenwände e, f, g zickzackförmig herum und gelangen dann durch die Siederrohre h des Dampfkessels a in den Seitenabzugskanal i des Dampfkessels, aus dem sie in den Schornstein übergehen. Die Verbrennungsgase geben auf dem ersten Teil ihres Weges ihre Wärme in der Hauptsache an die Sieder k ab. Die in dem Verbrennungsgase enthaltenen unverbrannten Gase treffen bei ihrer ersten Abwärtsbewegung zwischen den Wänden e, f auf die von dem Wanderrost fortgeführten glühenden Brennstoff- und Ascheteile, so daß sie dort zur Entzündung und Verbrennnung gelangen. Eine drehbare Klappe e, die unterhalb der Zwischenwand f angeordnet ist, sorgt dafür, daß die Verbrennungsgase unmittelbar auf denWanderrost c geleitet werden. Außerdem kann damit der Zug für die Feuerung eing, regelt werden.Below a steam boiler a, a step grate b and a traveling grate c are arranged with respect to one another in such a way that the fuel poured onto the step grate from above gradually comes to combustion. The still glowing fuel and ash residues falling on the traveling grate c are gradually conveyed by the traveling grate c after the ash has dropped out. The combustion gases move from the step grate b, while the steam boiler a is heated, around partition walls e, f, g in a zigzag shape and then pass through the boiler pipes h of the steam boiler a into the side exhaust duct i of the steam boiler, from which they pass into the chimney. On the first part of their way, the combustion gases give off their heat mainly to the boiler k. During their first downward movement between the walls e, f , the unburned gases contained in the combustion gases hit the glowing fuel and ash particles carried away by the traveling grate, so that they ignite and burn there. A rotatable flap e, which is arranged below the intermediate wall f, ensures that the combustion gases are directed directly onto the moving grate c. It can also be used to regulate the draft for the furnace.

Selbstverständlich kann man in der Nähe dieser Drosselklappe l auch noch LuftzuführungsFOhre oder Kanäle einbauen, die den dort zu verbrennenden Gasen die nötige Verbrennungsluft zuführen.Of course you can also do this in the vicinity of this throttle valve still install air supply pipes or ducts that carry the gases to be burned there supply the necessary combustion air.

Die über den Wanderrost geleiteten Verbrennungsgase werden durch die Zwischenwand g nochmals zickzackförmig um den Wassermantel der Siederohre geleitet, so daß das darin umlaufende Wasser des Dampfkessels schnell erwärmt wird. Die Temperatur des Wassers in dem Wassermantel wird noch weiter dadurch gesteigert, daß die Verbrennnungsgase zum Schluß durch das innenliegende Siederohr h hindurchgeführt werden, ehe sie durch einen Seitenkanal i in den Schornstein gelangen.The combustion gases passed over the traveling grate are through the Partition g again guided in a zigzag shape around the water jacket of the boiler pipes, so that the circulating water of the steam boiler is heated quickly. The temperature of the water in the water jacket is further increased by the fact that the combustion gases finally be passed through the inner boiler tube h before it through a side channel i get into the chimney.
