Description
Vorrichtung zum mischen von Brennstoff und Primärluft bei Kohlenstaubfeuerungen. Es ist eine Kohlenstaubfeuerung vorgeschlagen worden, bei welcher ein vollkommenes Gemisch von Kohlenstaub und Luft verwendet und die Luft so stark erhitzt wird, daß der Brennstoff schon vor der Düse teilweise entgast wird. Die Durchführung dieses Verfahrens erfordert eine sehr vollkommene Vorrichtung zum Mischen des Brennstoffes mit der Primärluft, und eine solche Vorrichtung bildet den Gegenstand der vorliegenden Erfindung. Die Vorrichtung ist beispielsweise in der. Zeichnung veranschaulicht, von der Abb. i einen senkrechten Schnitt und Abb. a einen Querschnitt durch die Linie A-A der Abb. i darstellt.Device for mixing fuel and primary air in pulverized coal firing. A pulverized coal furnace has been proposed in which a perfect Mixture of coal dust and air is used and the air is heated so much that the fuel is partially degassed before the nozzle. Carrying out this The process requires a very sophisticated device for mixing the fuel with the primary air, and such a device forms the subject of the present invention Invention. The device is for example in the. Drawing illustrates from Fig. i a vertical section and Fig. a a cross section through the Line A-A of Figure i represents.
a ist ein Fülltrichter zur Aufnahme des gepulverten Brennstoffes. An diesen schließt sich ein geräumiger, in der Abbildung im wesentlichen - kegelförmiger Rotationskörper b an, der den Mischraum bildet. Die Öffnung zwischen dem Mischrauim und dem Fülltrichter ist bis auf einen engen, regelbaren Schlitz durch einen langsam drehbaren, geriffelten Kegel o. dgl. c abgeschlossen. Der Brennstoffstaub wird daher in Form einer dünnwandigen Röhre in den Mischraum gestreut.a is a filling funnel for receiving the powdered fuel. This is followed by a spacious one, which in the picture is essentially conical Rotary body b, which forms the mixing space. The opening between the mixed room and the hopper is except for a narrow, adjustable slot completed by a slowly rotating, fluted cone or the like. c. The fuel dust is therefore scattered into the mixing space in the form of a thin-walled tube.
Der Mischraum ist von einem zweiten Mantel d, dl umgeben; in den Zwischenraum e wird erhitzte Luft geleitet, die durch ein Drosselventil f in den Mantelraum e1 und von da durch schief gestellte Schlitze g in den Mischraum b gelangt. In diesem erzeugt die schief zum Umfange eintretende Luft eine gleichmäßige Wolke des Brennstoffstaubes, die dann durch eine Doppeldüse i nach der Verbrennungsstelle geführt wird. Die zur Speisung der Düse dienende Druckluft tritt durch die Leitung hin den Mantelraum e und wird durch ein Drosselventil Z geregelt. m, m sind Explosionsventile.The mixing space is surrounded by a second jacket d, dl; Heated air is passed into the space e, which passes through a throttle valve f into the shell space e1 and from there through slits g placed at an angle into the mixing space b. The air entering at an angle creates a uniform cloud of fuel dust, which is then guided through a double nozzle i to the combustion point. The compressed air used to feed the nozzle enters the jacket space e through the line and is regulated by a throttle valve Z. m, m are explosion valves.
Kohle und Luft werden ununterbrochen zugeführt. Der Mischraum b ist als Autoklau gestaltet, so daß im. Innern ein Überdruck bestehen kann, ohne daß dadurch die zwangläufige Beschickung mit Kohlenstaub gestört wird. .Coal and air are supplied continuously. The mixing space b is designed as a car theft, so that im. Inside an overpressure can exist without thereby the inevitable charging with coal dust is disturbed. .
