Abstract (en)

[origin: WO2006069861A1] Disclosed are a premix burner comprising a mixing section (3) for a heat generator as well as a method for operating such a premix burner. The inventive premix burner further comprises partial conical shells (5) which complement each other so as to form a swirling member while embracing a swirl chamber (6) that expands in a conical manner. The partial conical shells (5) delimit mutually tangential air inlet slots (7) along which inlets (8) for gaseous fuel are distributed. The premix burner also comprises at least one liquid fuel inlet which is disposed along a burner axis (A) that centrally penetrates the swirl chamber (6) as well as a mixing tube (4) which adjoins the swirling member downstream via a transition piece (2). The invention is characterized in that at least one additional inlet (13) for liquid or gaseous fuel is provided in the area of the swirling member, the transition piece (2), and/or the mixing tube (4).
