US 7,114,910 B2 · Method and injection nozzle for interspersing a gas flow with liquid droplets

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.

Dependent claims

A method for interspersing a gas flow with fluid droplets, wherein the fluid droplets are injected into the gas flow having a boundary layer, characterized in that

an auxiliary gas is injected simultaneously with the fluid droplets into the gas flow, wherein the injection speed of the auxiliary gas is larger than the injection speed of the fluid droplets,
so that the injected auxiliary gas entrains and accelerates the injected fluid droplets into the gas flow, stabilizes the injected fluid droplets with respect to its trajectory and size, and partly shields the injected fluid droplets from the gas flow in order to enable a penetration of the gas flow boundary layer by the injected fluid droplets.
