ABSTRACT:
A premixing burner has a swirl generator with at least two burner shells (1) which jointly enclose an axia conically widening swirl space and delimit tangential air inlet slits (3) through which combustion supply air passes into the swirl space in which an axially propagating swirl flow is formed, and with fuel injection devices at least partially along the tangentially running air inlet slits (3). The fuel injection devices include a fuel line (6) separate from the burner shell (1) and which is firmly attached to the burner shell (1) so as to be longitudinally movable with respect to the burner shell (1) and releasable perpendicularly to the surface of the burner shell (1). In the burner shell (1), orifices (4) are provided, into which issue fuel injectors (7) which are provided along the fuel line (6) and which project beyond the circumferential edge of the fuel line (6).
