摘要

The mixer arrangement has a pre-mixer and a main mixer that has a main housing, multiple fuel injection openings for spraying fuel in an annular hollow chamber and a spin generator arrangement. The spin generator of the arrangement spins air that flows through the spin generator to mix air and the fuel droplets released from the fuel injection openings. A central body is positioned between the pre-mixer and the main mixer. The central body has a fuel distributor to supply fuel to the fuel injection openings and an air distributor to supply air to the rear area of the pre-mixer.
