Abstract

Die Erfindung betrifft eine Düse für einen Gasbrenner, wobei die Düse einen Kanal aufweist, der zum Abgeben von Gas vorgesehen ist, wobei der Kanal an einer Austrittsöffnung endet, wobei ein Strömungselement außerhalb der Austrittsöffnung angeordnet ist, wobei das Strömungselement einen ersten Abschnitt aufweist, der ausgehend von einem ersten Durchmesser in Richtung weg von der Austrittsöffnung bis zu einem zweiten Durchmesser zunimmt, wobei das Strömungselement ausgehend vom zweiten Durchmesser in einem zweiten Abschnitt mit zunehmendem Abstand von der Austrittsöffnung im Durchmesser wieder bis zu einem dritten Durchmesser abnimmt, wobei das Strömungselement rotationssymmetrisch zu einer Mittenachse des Kanals ausgebildet und angeordnet ist.
