Description
Brennstaubfeuerung für Flammrohrkessel. Die Erfindung betrilt eint, 13rinnnstaubfeuerung für Flammrolirkessel mit vorgelagerter Verbrennungskammer. Nach der @rfndung wird der Kammer die Zusatzluft in an sich bekannter «@ eise am Umfang durch zahlreiche, über die ganze Länge der Wand verteilte tangential ausmündende Kanäle und das Brennstaubluftgemisch von der Stirnseite heizugeführt. Aus dieser Ausbildung der Verbrennungskammer ergeben sich wesentliche Vorteile für den Betrieb. Vor dem Eintritt der Verbrennungsgase in das Flammrohr soll eine möglichst vorteilhafte und vollkommene Verbrennung des Kohlenstaubes erzielt werden, und die heißen Gase sollen dann nach Ausscheidung der Staub- und Schlackenteile in das Flammrohr übertreten. Dieser Bedingung genügt die neue Ausbildung der Verbrennungskammer in hohem Maße. Dic Kohlenstaubteilchen legen in der Kammer einen sehr langen Vexbrennungsweg zurück wnd kommen dabei immer wieder mit frischer Luft in Berührung. Die schwereren, erst später verbrennenden Staubteilchen werden immer wieder der Verbrennungsluft entgegengeschleudert, und es erfolgt ein Ausscheiden der Staub- und Schlackenteilchen durch die-Schleuderwirkung. In das Flammrohr treten von staub- und brennbaren Teilen freie Verbrennungsgase in flachen Spiralbewegungen ein, die bekanntlich die Wärmeabgabe an die Flammrohrwand begünstigen.Dust combustion for flame tube boilers. The invention concerns one Duct dust firing for flame roller boilers with upstream combustion chamber. After the discovery, the additional air is supplied to the chamber in a manner known per se Circumference through numerous tangential openings distributed over the entire length of the wall Channels and the pulverized fuel air mixture are heated from the front. From this Design of the combustion chamber results in significant advantages for the operation. Before the combustion gases enter the flame tube, one should be as advantageous as possible and perfect combustion of the coal dust can be achieved, and the hot gases should then pass into the flame tube after the dust and slag parts have been separated out. The new design of the combustion chamber satisfies this condition to a large extent. The coal dust particles cover a very long combustion path in the chamber wnd come into contact with fresh air again and again. The heavier ones, first Dust particles that burn later are thrown again and again towards the combustion air, and the dust and slag particles are separated out by the centrifugal effect. Combustion gases free from dusty and combustible parts enter the flame tube in flat spiral movements, which is known to reduce the heat dissipation to the flame tube wall favor.
In der Zeichnung ist eine Ausführungsform der Vorrichtung dargestellt. Es zeigen: Abb. i einen Längsschnitt, Abb. 2 einen Querschnitt.In the drawing, an embodiment of the device is shown. They show: Fig. I a longitudinal section, Fig. 2 a cross section.
Dem Flammirohr ist eine Verbrennungskammer a von kreisförmigem Querschnitt vor gelagert. Dieser wird der Brennstoff durch den Stutzen i zugeführt, der hinter der Klappelz angebracht ist. Infolge der kung der Spiralen k tritt der Brennstoff in drehender Bewegung in die Verbrennungskammer ein und wird an die Wandung geschleudert, durch deren Sclilitzezn die Zu-Satzluft eintritt. Die Schlitze in sind auf die Länge der Kammer verteilt und tangential. angeordnet. Der Austritt _ der Luft aus den Schlitzen kann in Richtung der Brennstoffbewegung oder auch eiitgc#gengesetzt gerichtet erfolgen. Infolge der Drehbewebung ist der Verbrennungsweg für die einzelnen Brennstoffteilchen auPerordentlich verlängert. Die ,größeren, schwer verbrennlichen Teilchen werden dabei immer wieder der frischen Verbrennungsluft entgegengeschleudert. Die ausgeschleuderten Schlackenteilchen gelangen in den Schlackenabzug 1. Die Verbrennungskamiuer ist von mehreren - Luftkammern b umschlossen, denen die Luft durch die Leitung c zugeführt wird. Jeder Luftkammer ist eine Regelvorrichtung e vorgeschaltet. Zur Regehing der gesamten Verbrennungsluftmenge dient die Absperrvorrichtung f . Klan kann den Kammern b auch Dampf aus einer mit Absperrvorrichtungen g versehenen Leitung d zuführen. Der Dampf wird beim Durchgang durch die heiße -Tand der Verbrennungskammer oder unmittelbar nach seinem Austritt zersetzt und dient so zur Förderung der Verbrennung. Außerdem wirkt er kühlend auf die Kammerwand.The flame tube has a combustion chamber a of circular cross section before stored. This is fed the fuel through the nozzle i, which is behind the folding fur is attached. As a result of the kung of the spirals k, the fuel occurs enters the combustion chamber in a rotating motion and is thrown against the wall, through whose slot the additional set air enters. The slots in are on the length the chamber distributed and tangential. arranged. The exit of the air from the Slots can be directed in the direction of fuel movement or in the opposite direction take place. The combustion path for the individual fuel particles is due to the rotational movement extraordinarily extended. The bigger, hard to burn particles will be repeatedly thrown against the fresh combustion air. The ejected Slag particles get into the slag discharge 1. The combustion chamber is open enclosed by several - air chambers b, to which the air is supplied through line c will. A control device e is connected upstream of each air chamber. Regehing the the entire amount of combustion air is used by the shut-off device f. Klan can do the chambers b also supply steam from a line d provided with shut-off devices g. The steam is when passing through the hot -and the combustion chamber or decomposes immediately after its exit and thus serves to promote combustion. It also has a cooling effect on the chamber wall.
