Abstract
In a premix burner having a swirl-stabilizing interior space (20) which is essentially formed by sectional shells (11, 12) nested one inside the other in a mutually offset manner as well as by a conically running inner body (13), one feed duct (11c, 12c) each extends upstream of the tangential air-inlet slots (11a, 12a) formed by the offset sectional shells, which feed duct (11c, 12c) is fitted at least with means (11d, 12d) for swirling an air flow (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.
