Abstract
In the method for interspersing a gas flow (8) with fluid droplets (5), the fluid droplets (5) are injected in a fluid injection plane into the gas flow (8), characterised in that an auxiliary gas (6.1, 6.2) is simultaneously injected with the fluid droplets (5) into the gas flow (8). The injection speed of the auxiliary gas (6.1, 6.2) is larger than the injection speed of the fluid droplets (5) so that the injected auxiliary gas (6.1, 6.2) stabilises the injected fluid droplets (5) with respect to trajectory and size, partly shields them from the gas flow (8) and/or entrains them into the gas flow (8). By way of this one achieves an improved control of the spatial distribution of the fluid droplets (5) and their size distribution. The fluid droplets (5) penetrate the gas flow (8) more efficiently than without an auxiliary gas (6.1, 6.2). A preferred use is the online wet-cleaning of a gas turbine compressor.
