Bekannte Drehofenbrenner sind meist als sogenannte Dreikanalbrenner ausgebildet (z. B.
Die zum Kohlenstaub radial äußere Brennluft des Drehofenbrenners, auch Jetluft genannt, wird mittels einer Vielzahl im ringförmigen Jetluftkanal angeordneter einzelner Düsen in viele einzelne Hochgeschwindigkeits-Primärluftstrahlen unterteilt, die in ihrer Umgebung ein Unterdruckgebiet erzeugen, das heißt die vielen Hochgeschwindigkeits-Primärluftstrahlen dienen als Treibstrahlen nach dem Injektorprinzip, durch welches die große Masse der den Drehofenbrenner umgebenden, praktisch ruhenden heißen Sekundärluft von z. B. etwa 1000 °C nach innen in Richtung zum Kern der Brennerflamme eingesaugt wird, wo eine intensive Durchmischung der heißen Sekundärluft mit dem durch die Ringspaltdüse austretenden Kohlenstaub stattfindet, der schnell und vollständig unter Ausbildung einer meistens geforderten kurzen heißen Flamme verbrennen soll. Zur Verstellung des Divergenzwinkels der Jetluftstrahlen sind die zylindrischen Düsenkörper mit ihren zur Düsenachse mit einem Winkel angestellten Düsenbohrungen einzeln verdrehbar, allerdings nicht während des Drehofenbetriebes, so dass während des Ofenbetriebes nicht durch Verstellung des Divergenzwinkels der Jetluftstrahlen Einfluss auf die optimale Kohlenstaub-Jetluft-Durchmischung sowie Flammenform genommen werden kann.The combustion air of the rotary kiln burner, also referred to as jet air, which is radially external to the pulverized coal, is determined by means of a plurality in the annular jet air duct arranged individual nozzles in many individual high-speed primary air jets, which generate a negative pressure area in their environment, that is, the many high-speed primary air jets serve as propulsion jets according to the injector, through which the large mass of the rotary kiln surrounding, practically stationary hot secondary air of z. B. is sucked inward towards the core of the burner flame, for example, where intensive mixing of the hot secondary air takes place with the exiting through the annular nozzle coal dust, which is to burn quickly and completely to form a mostly required short hot flame. To adjust the Divergenzwinkels the jet air jets, the cylindrical nozzle body with their nozzle axis with an angle hired nozzle holes are individually rotatable, but not during the rotary kiln operation, so that during the furnace operation not by adjusting the Divergenzwinkels the jet air jet influence on the optimum pulverized coal jet air mixing and Flame shape can be taken.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, einen Drehofenbrenner insbesondere für feinkörnige Festbrennstoffe zu schaffen mit Jetluftdüsen, die zwecks Änderung des Divergenzwinkels der Jetluftstrahlen auch in Reaktion auf unterschiedliche Brennstoffarten und/oder sich ergebender Flammenformen einfach und doch wirkungsvoll während des Drehofenbetriebes verstellbar sind.The invention has for its object to provide a rotary kiln burner, especially for fine-grained solid fuels with jet air nozzles that are easy and yet effectively adjustable during the rotary kiln operation in order to change the Divergenzwinkels the jet air jets in response to different types of fuel and / or resulting flame shapes.

Dabei sind die Jetluftrohre im Kühlluftringkanal verdrehbar gelagert, wobei am kalten Ende der Brennerlanze außerhalb des Brennertragrohres die Einrichtung zur Drehverstellung der Jetluftrohre angeordnet ist. Damit gelingt es, je nach eingestellter Drehstellung der Jetluftrohre und der von diesen getragenen Jetluftdüsen die Jetluftstrahlen divergent, radial oder konvergent zur Brennerachse austreten zu lassen, und es gelingt, den Divergenzwinkel der Jetluftstrahlen so einzustellen, dass der Jetluftkegel den Brennstoffkegel zwecks größtmöglicher Flammenturbulenz optimal trifft, wodurch eine Veränderung und Einstellung der Flammenform des Drehofenbrenners während des Drehofenbetriebes möglich ist. Dadurch, dass die verdrehbaren Jetluftrohre in den äußeren ringförmigen Kühlluftkanal des Brenners verlegt sind, ergibt sich auch eine kompakte Bauweise des erfindungsgemäßen Drehofenbrenners.In the rotary kiln burner according to the invention, the jet air nozzles are attached to the burner axis diverging nozzle openings respectively at the end of jet air ducts, which are arranged axially parallel to the burner axis, within a ring surrounding the solid fuel channel outside of the combustion liner limited cooling air ring channel. In this case, the jet air pipes are rotatably mounted in the cooling air ring channel, wherein at the cold end of the burner lance outside of the combustion liner, the means for rotational adjustment of the jet air pipes is arranged. This makes it possible, depending on the set rotational position of the jet air ducts and carried by these Jetluftdüsen the jet air jets to emerge divergent, radially or convergent to the burner axis, and it succeeds to adjust the Divergenzwinkel the jet air jets so that the Jetluftkegel optimally hits the fuel cone for the purpose of maximum flame vortex , whereby a change and adjustment of the flame shape of the rotary kiln burner during the rotary kiln operation is possible. The fact that the rotatable jet air pipes are laid in the outer annular cooling air duct of the burner, also results in a compact design of the rotary kiln burner according to the invention.

Als Variante hierzu können aber auch an die einzeln bzw. gemeinsam jeweils um ihre Längsachsen verdrehbaren Jetluftrohre an ihren äußeren von den Jetluftdüsen entfernten Enden flexible Schläuche zur Jetluftzuführung in die Jetluftrohre angeschlossen sein.The bearings of the individual jet air pipes are held in two spaced apart flange rings of the combustion liner. According to a further feature of the invention, the annular space between the spaced flange rings can be formed within the provided with a jet air supply nozzle fuel return pipe as inflow, from which the supplied jet air flows through through holes of the jet air pipes into this and then flows out of the jet air nozzles. As a variant of this, flexible hoses for supplying jet air into the jet air pipes can also be connected to the jet air pipes which can be rotated individually or jointly about their longitudinal axes at their outer ends remote from the jet air nozzles.

Zahnritzel tragen, die mit einem mit Innenverzahnung versehen Ring oder Band in Verdreheingriff stehen.As a means for rotational adjustment of the jet air ducts, these can at their outer ends z. B. pinion, which are provided with an internal toothing ring or belt in twisting engagement.
