    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: PROBLEM TO BE SOLVED: To provide a pulverized coal burner that reduces the NOx concentration in combustion gas, while maintaining ignitability using a simple structure.
    SOLUTION: In this pulverized coal burner (20) having an oil nozzle (6), a primary air nozzle (1), a pulverized coal nozzle (4), and air nozzles (2, 3), a fixed plate (15) and a movable member (16) are arranged on the inner peripheral wall of the front end of the primary air nozzle (1); the fixed plate (15) is provided with slit holes (15a), each having a pair of opposed wall surfaces having an opening area gradually reduced from the upstream side to the downstream side; the movable member is mounted upstream of the fixed plate in the primary air nozzle (1) so as to be able to advance and retract; the movable member has grids (16a), adapted to close the slit holes (15a) and arranged in a radial pattern, at positions that correspond to the slit holes (15a); the degree of insertion for each grid (16a) into a corresponding slit hole (15a) is adjusted, to close either of a pair of gaps formed between the grid (16a) or a pair of opposed surfaces of the slit hole, and to cause primary air ejected from the other gap to swirl; and the swirl flow of the primary air is ejected into a furnace, to facilitate mixing of the primary air with atomized oil ejected from the oil nozzle (6).
