Abstract (en)
[origin: EP0157691A1] 1. A device for atomising a liquid into a gaseous flux, characterised in that it comprises at least two venturis disposed coaxially in series, in which said gaseous flux flows, and in the neck (1) of the venturi disposed furthest upstream at least one means (21) for injecting said liquid into said gaseous flux, the dimensions of the venturis being such that in each venturi the velocity of the gaseous flux is sonic at the level of the neck and supersonic downstream thereof, over a fraction of the divergent which follows this neck, and if Pin designates the generating pressure of fluid at the neck of the venturi of row _n and Sn designates the section of said neck, the equation Pin Sn = Pin+1 Sn+1 results.
