Abstract:
1. A premix burner for a heat generator, the burner comprising: a conically widening chamber with an inside diameter defining the size of a vortex chamber and an axial length defining the length of the premix burner; at least five partial cone shells making up a vortex generator encompassing the vortex chamber, wherein the partial cone shells mutually define tangential air inlet slots having slot widths and an outside premix burner diameter; wherein the cone shells are configured and arranged to inject at least one gaseous fuel or liquid fuel along the air inlet slots; and a feed arranged along a burner axis which centrally passes though the vortex chamber; wherein the premix burner is configured so that the output capacity of the premix burner is greater than the output capacity of a premix burner with the same burner length, inside diameter, and outside diameter, and less than five said partial cone shells by the number of partial cone shells, and the shape and size of the cone shells that define inlet slot widths being at least the same size as a burner with less than five said partial cone shells.
