    摘要: An injector (4) for liquid fuel (6a) and a premix burner, in particular for combustion chambers of gas turbines which burner includes an injector (4) of this type, includes a swirl nozzle (14) which is surrounded by a shielding-air passage (11) and has an enlarged cross section of flow in the region of a nozzle-internal swirl generator (12) for the liquid fuel (6a), with this enlarged cross section of flow being reduced again toward an exit opening of the swirl nozzle (14). The injector allows the premix burner to operate with a reduced admission pressure and a high atomization quality.

    摘要: What are described are a multiple burner arrangement and a method for operating such a multiple burner arrangement with a multiplicity of individual burners which are designed as premix burners and which serve for firing a combustion chamber of a thermal engine and each have a swirl space into which combustion supply air and fuel can be introduced so as to form a swirl flow, the swirl flow forming downstream of the premix burner, within the combustion chamber, a backflow zone in which a burner flame is formed.
