Abstract

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