Abstract: Die Erfindung umfasst einen Kombinationsbrenner für die Vergasung staubförmiger Brennstoffe mit einem freien Sauerstoff enthaltenden Oxidationsmittel bei Umgebungs- oder höheren Drücken, sowie Temperaturen zwischen 800-1800 o C, wobei die Zündvorrichtung des Pilotbrenners mit Flammüberwachung und der Staubbrenner als Kombinationsbrenner integriert sind und alle Betriebskanäle voneinander getrennt bis zum Brennermund geführt und die von den Kanälen geführten Medien erst am Brennermund gemischt werden. Bei Demontage des Pilotbrenners können die auf seiner Hülle befestigten Wirbelkörper (14) in der Hauptbrenneroxydationsmittel-Zuführung (17) schnell und einfach gewechselt werden und somit die Hauptbrennerflamme optimal an die Reaktionsraumkontur des Reaktors angepasst werden.

Abstract: A burner ignited by plasma includes at least two stage of burning cylinders (104, 106) and a plasma generator (302) for igniting the pulverized coal in the first burning cylinder (104) of the at least two stage of burning cylinders (104, 106). The burning flame of the previous burning cylinder (104) ignites the pulverized coal in the subsequent burning cylinder (106), or further combusts with auxiliary air in the subsequent burning cylinder (106). The burner is characterized in that the axial direction of the plasma generator (302) is parallel with the direction of the air containing pulverized coal entering the first burning cylinder (104),and simultaneously parallel with the axis of the burning cylinders (104, 106).
