Abstract (en)

[origin: DE19713377A1] The invention relates to a nozzle (1) for injecting a first fluid (10), especially fuel, into a second fluid (11), especially combustion air. The first fluid (10) is guided by two channels (3, 4) in the nozzle, one of said channels (4) flowing eccentrically into the other channel (3) so as to produce a swirled main flow (10c) which is then able to penetrate far into the second fluid (11). The swirl causes the injected, first fluid (10) to fan out, and thus become finely divided. The invention also relates to an application for a nozzle of this type (1) in a premix burner of a gas turbine, and to a corresponding method.
