Claims (13)

  1. Brenner mit zentralem Luftstrahl, der Folgendes umfasst:
    eine axiale Zone (25), die von einer ersten ringförmigen Zone (11) konzentrisch umgeben ist, wobei die erste ringförmige Zone von einer zweiten ringförmigen Zone (16) konzentrisch umgeben ist und die zweite ringförmige Zone von einer dritten ringförmigen Zone (17) konzentrisch umgeben ist, wobei die axiale Zone, die erste ringförmige Zone, die zweite ringförmige Zone und die dritte ringförmige Zone durch ein axiales Rohr (6), ein ringförmiges Rohr (3) bzw. eine Trommel (19) getrennt sind,
    eine Zufuhrleitung (9), die zwischen einem Abschnitt der ersten ringförmigen Zone (11) und der axialen Zone (25) radial eingeschoben ist, wobei die Zufuhrleitung (9) die axiale Zone (25) mit einem Gas, das Sauerstoff umfasst, versorgt,
    Mittel (10) zum Regulieren des Gasflusses durch die Zufuhrleitung (9);
    Mittel zum Versorgen der ersten ringförmigen Zone mit einem brennbaren Kraftstoff;
    Mittel zum Versorgen der zweiten ringförmigen Zone mit Luft, und Mittel zum Versorgen der dritten ringförmigen Zone mit Luft, wobei die axiale Zone und die zweite und die dritte ringförmige Zone Sekundärluft für die Verbrennung bereitstellen, und wobei das Gas, das Sauerstoff umfasst, aus der axialen Zone austritt, um den zentralen Luftstrahl zu bilden.
  2. Brenner nach Anspruch 1, wobei die axiale Zone eine Durchflusskonditionierungsvorrichtung (13) enthält.
  3. Brenner nach Anspruch 1 oder Anspruch 2, wobei die erste ringförmige Zone eine Durchflusskonditionierungsvorrichtung (30) enthält.
  4. Brenner nach einem der vorhergehenden Ansprüche, wobei die erste ringförmige Zone Mittel (7) zum Bereitstellen einer gleichmäßigeren Kohleverteilung enthält.
  5. Brenner nach Anspruch 1 bis 4, der ferner in der zweiten ringförmigen Zone eine Schaufel (21) umfasst.
  6. Brenner nach Anspruch 1 bis 5, der ferner in der dritten ringförmigen Zone eine Schaufel (22, 23) umfasst.
  7. Brenner nach Anspruch 1, der ferner Mittel (15) zum Regulieren des Luftflusses in die zweite ringförmige Zone und Mittel (15) zum Regulieren des Luftflusses in die dritte ringförmige Zone umfasst.
  8. Brenner nach einem der vorhergehenden Ansprüche, wobei sich ein Brennerluftkasten (51) in fluidtechnischer Kommunikation mit der zweiten ringförmigen Zone und der dritten ringförmigen Zone befindet.
  9. Brenner nach Anspruch 8, wobei sich der Brennerluftkasten in fluidtechnischer Kommunikation mit der axialen Zone befindet.
  10. Brenner nach einem der vorhergehenden Ansprüche, wobei sich in der axialen Zone ein Zünder befindet.
  11. Brenner nach einem der vorhergehenden Ansprüche, der ferner eine Leitungsröhre umfasst, die von der axialen Zone konzentrisch umgeben ist.
  12. Brenner nach Anspruch 11, wobei die Leitungsröhre Mittel zum radialen Verteilen eines Gases in die axiale Zone umfasst.
  13. Brenner nach Anspruch 11 oder 12, wobei die Leitungsröhre Mittel umfasst, um ein Gas in Längsrichtung in der axialen Zone zu verteilen.
