Abstract

Bei einem Brenner, der im wesentlichen aus einem Drallerzeuger (100) für einen Verbrennungsluftstrom (115) und aus Mitteln zur Eindüsung eines Brennstoffes in den Verbrennungsluftstrom (115) besteht, ist stromab des erwähnten Drallerzeugers eine Mischstrecke (220) angeordnet. Diese Mischstrecke (220) weist innerhalb einer ersten Teilstrecke (200) eine Anzahl von in Strömungsrichtung verlaufenden Uebergangskanälen (201), welche die nahtlose Ueberführung der im Drallerzeuger (100) gebildeten Strömung (40) in ein nachgeschaltetes Mischrohr (20) sicherstellen. Die Austrittsebene dieses Mischrohres (20) zur Brennkammer (30) ist mit einer Abrisskante ausgebildet, welche der Stabilisierung und Vergrösserung einer sich stromab bildenden Rückströmzone (50) dient. Konzentrisch zur Mischstrecke (220) ist eine Anzahl Mischelemente (300) vorgesehen, welche der Bildung eines Gemisches (304) aus Verbrennungsluft (115a) und einem Brennstoff (303) dienen. Dieses Gemisch (303) aus dem jeweiligen Mischelement (300) bildet dann jeweils eine Pilotstufe der Brennkammer (30).
