Abstract

Bei einem Brenner der Doppelkegelbauart sind in der Brennersichel (26) Bohrungen (27) angeordnet, über die gasförmiger Brennstoff (16) im Umfang von ca. 3 bis 8% des Gesamtbrennstoffmassenstromes in die äussere Rezirkulationszone (28) des Brenners eingemischt wird. Das führt zu einer zusätzlichen äusseren Stabilisierung der Flamme und zu einer Erweiterung des Betriebsbereiches des Brenners.
