Description

Brenneubfeuerung Gegenstand des Hauptpatentes ist eine Brennstaubfeuerung mit Trocknung des Brennstoffes in einer vor dem Verbrennungsraum angeordneten, der Strahlung des Verbrennungsraumes ausgesetzten Kammer. Das Wesen der Erfindung gemäß dem Hauptpatent besteht darin, daß der jener Kammer zufließende Brennstoff in ihr nicht nur getrocknet, sondern auch zerkleinert und durch einen Ouergasstrom gesichtet sowie der Feuerung zugeführt wird. Die Sichtung erfolgt bei der Feuerung nach dem Hauptpatent unter Zuhilfenahme einer besonderen, am unteren Ende der Kammer vorgesehenen Zerkleinerungsvorrichtung.Firing the subject of the main patent is a pulverized fuel firing with drying of the fuel in a arranged in front of the combustion chamber, the Chamber exposed to radiation from the combustion chamber. The essence of the invention according to the main patent consists in the fact that the fuel flowing into that chamber is in it not only dried, but also crushed and sifted through a stream of Ouergas as well as being fed to the furnace. The sighting takes place during the firing after the Main patent with the help of a special one provided at the lower end of the chamber Shredding device.

Neuere Untersuchungen haben ergeben, daß die Benutzung der besonderen Zerkleinerungsvorrichtung unnötig ist, und daß der von oben in die Kammer fallende Brennstoff auch nur durch Anwendung eines von unten in die Kammer geleiteten Preßluftstromes genügend zerkleinert werden kann. Hierbei wirkt dieser Preßluftstrom in der Weise, daß er die von oben zugeführten Brennstoffteilchen gegen die obere Begrenzung der Kammer schleudert und den Brennstoff dadurch zerkleinert.Recent studies have shown that the use of the special Crushing device is unnecessary, and that the falling from above into the chamber Fuel also only by using a stream of compressed air directed into the chamber from below can be crushed sufficiently. Here this compressed air flow acts in the way, that he the fuel particles supplied from above against the upper limit of the Chamber spins and thereby crushes the fuel.

In der Zeichnung ist die Erfindung schematisch an einem Ausführungsbeispiel veranschaulicht. Vor dem Verbrennungsraum a ist die besondere Kammer b angetirdnet, der aus dem Bunker c Brennstoff zufließt. Am unteren Ende der Kammer b ist eine Zuführung g für Preßluft vorgesehen, so daß die gröberen Brennstoffteile den durch Pfeile angedeuteten Weg in der Kammer b zurücklegen. Die staubförmigen Teilchen des Brennstoffes werden durch den vom Kanal e zum Verbrennungsraum d strömenden Gasstrom erfaßt und dem Verbrennungsraum a zugeführt.In the drawing, the invention is shown schematically in an exemplary embodiment illustrated. In front of the combustion chamber a is the special chamber b, the fuel flows in from the bunker c. At the bottom of chamber b is one Supply g provided for compressed air, so that the coarser fuel parts through Cover the path indicated by the arrows in chamber b. The dusty particles of the fuel are flowing through the channel e to the combustion chamber d Detected gas flow and fed to the combustion chamber a.

PATENTANSPRUCH: Brennstaubfeuerung mit Trocknung des Brennstoffes in einer vor dem Verbrennungsraum angeordneten, der Strahlung des Verbrennungsraumes ausgesetzten Kammer nach Patent 5o8gig, dadurch gekennzeichnet, daß die Zerkleinerung des Brennstoffes durch vorteilhaft am unteren Ende (bei g) zugeführte Preßluft erfolgt, die die größeren Kohleteilchen gegen die gegenüberliegende Wand schleudert, während die bereits brennreifen kleinen Kohleteilchen durch den ()uergasstrom dem Verbrennungsraum zugeführt werden. 'PATENT CLAIM: Dust firing with drying of the fuel in one arranged in front of the combustion chamber, the radiation of the combustion chamber exposed chamber according to patent 5o8gig, characterized in that the comminution of the fuel is carried out by compressed air advantageously supplied at the lower end (at g), which hurls the larger coal particles against the opposite wall while the already burning small coal particles through the () external gas flow into the combustion chamber are fed.
