Abstract
The system incorporates a static mixer having a tube accommodating a number of fixed components cutting into and diverting currents of fluids, and giving a high degree of turbulence at the rate of flow desired. At the downstream end of the mixer tube is a nozzle, imparting to the jet of liquid the profile desired. An auxiliary gas is injected into the mixer, together with one or more liquids, rates and pressure being such that gas release atomizes and propels the liquids concerned. The gas can be air, nitrogen, water vapour or dichloro-difluormethane.
