Abstract
In a premix burner (100) for a heat generator, which essentially comprises at least two hollow, conical sectional bodies (101, 102) nested one inside the other in the direction of flow, the longitudinal symmetry axes (101b, 102b) of the sectional bodies are offset from one another in such a way that the adjacent walls of these sectional bodies form air-inlet slots (119, 120), tangential in their longitudinal extent, for the throughflow of combustion air (115). On the head side, the premix burner (100) has a fuel nozzle (103) which is shifted upstream by a distance (126) relative to the cone start (125) induced by the sectional bodies. Thus the fuel injection is caught by the combustion air only when the fuel spray cone can be penetrated more effectively, which leads to better mixture formation.
