Abstract

Bei einem Vormischbrenner mit einem drallstabilisierenden Innenraum (20), der im wesentlichen von zueinander versetzt und ineinandergeschachtelten Teilschalen (11, 12) sowie von einem kegelförmig verlaufenden Innenkörper (13) gebildet ist, erstreckt sich stromauf der von den versetzten Teilschalen gebildeten tangentialen Lufteintrittsschlitzen (lla, 12a) je ein Zuführungskanal (11c, 12c), der mindestens mit Mitteln (11d, 12d) zur Verwirbelung eines Luftstromes (23) und mit Mitteln zur Einbringung eines Brennstoffes (24) bestückt ist. Vorzugsweise wird die Einbringung des Brennstoffes stromab der Mittel zur Verwirbelung des Luftstromes angeordnet.

Figure 00000001
In the case of a premix burner with a swirl-stabilizing interior (20), which is essentially formed by partial shells (11, 12) which are nested and nested in one another and by a conical inner body (13), extends upstream of the tangential air inlet slots (lla , 12a) each have a feed channel (11c, 12c) which is equipped at least with means (11d, 12d) for swirling an air stream (23) and with means for introducing a fuel (24). The introduction of the fuel is preferably arranged downstream of the means for swirling the air flow.
