Method and jet nozzle for scattering droplets in a gas stream

摘要

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.
