Abstract

Bei einem Vormischbrenner, im wesentlichen bestehend aus einem Drallerzeuger (30) für einen Verbrennungsluftstrom (15), Mitteln (17, 17a, 17b, 31-38, 41-48) zur Einbringung von Brennstoff in den Verbrennungsluftstrom (15) und Lufteintrittsschlitzen (19, 20), tritt der Verbrennungsluftstrom (15) über Lufteintrittsschlitze in einen Drallraum (14) des Drallerzeugers (30) ein.In a premix burner, essentially consisting of a swirl generator (30) for a combustion air flow (15), means (17, 17a, 17b, 31-38, 41-48) for introducing fuel into the combustion air flow (15) and air inlet slots (19 , 20), enters the combustion air flow (15) via air inlet slots in a swirl chamber (14) of the swirl generator (30).

Die Eindüsung des Brennstoffes in die Verbrennungsluft erfolgt über die Eindüsungs-Mittel (17, 17a, 17b, 31-38, 41-48) asymmetrisch. Eines der Eindüsungsmittel (5) ist an einer in den Drallraum ragende Brennstofflanze (3) angeordnet.

Figure imgaf001
The injection of the fuel into the combustion air takes place asymmetrically via the injection means (17, 17a, 17b, 31-38, 41-48). One of the injection means (5) is arranged on a fuel lance (3) projecting into the swirl space.
