Abstract

Bei einem Verfahren und einer Vorrichtung zur Verbrennung von Brennstoffen in einer Hauptströmung aus Verbrennungsluft wird die Verbrennungsluft in einem Kanal (8, 20) über mindestens einen deltaförmigen Körper (40) geleitet. Der deltaförmige Körper besteht aus mindestens einem im wesentlichen dreieckförmigen Wirbelerzeuger-Bereich (1) und einem stromabwärts liegenden trapezförmigen Flammenstabilisierungs-Bereich (3). In der Region des Wirbelerzeuger-Bereiches (1) wird Brennstoff in die verwirbelte Verbrennungsluft eingeleitet. Der Wirbelerzeuger-Bereich (1) wird mittels eines halben Pfeilungswinkels (Φ1) und eines Anstellwinkels (α1) gegenüber der Hauptrömung so angestellt, dass der Drall der in der Hauptströmung induzierten Längswirbel kleiner ist als der kritische Drall zur Erzeugung einer Rezirkulationszone (5). Der Flammenstabilisierungs-Bereich (3) wird mittels eines halben Pfeilungswinkels (Φ3) und eines Anstellwinkels (α3) gegenüber der Strömung so angestellt, dass der Drall der in der Strömung induzierten Längswirbel grösser ist als der kritische Drall, wodurch je deltaförmigen Körper (40) ein Paar von kalottenförmigen Rezirkulationszonen (5) erzeugt und das entzündete Verbrennungsluft-Brennstoff-Gemisch stabilisiert wird.
