Abstract

Bei einem Vormischbrenner weist der drallstabilisierte Innenraum (18) einen in Strömungsrichtung verlaufenden kegelförmigen Innenkörper (13) auf. Die äussere Ummantelung des Innenraumes (13) ist durch tangential angeordnete Lufteintrittskanäle (11a, 12a) durchbrochen, durch welche ein Verbrennungsluftstrom (16) in den Innenraum (13) strömt. Die sich im Innenraum (13) bildende Drallströmung (23) wird über mindestens eine Brennstoffdüse (17) mit einem Brennstoff angereichert. Im nachgeschalteten Mischrohr (21) erfolgt dann die Gemischbildung der beiden Medien. Das Mischrohr (21) geht anschliessend über einen Querschnittssprung in einen Brennraum (31) über, wobei sich im Bereich der Ebene des Querschnittssprunges eine Rückströmzone (32) bildet, welche die Stabilität der Verbrennung gewährleistet.
