Summary:Appts. for combatting water-borne oil pollution comprises a boom mounting double swirl chamber nozzles each having a primary swirl chamber with a tangential inlet and an outlet orifice connected to a secondary swirl chamber. The chambers and their outlet orifices are coaxial. A pump delivers oil-dispersant compsn. to the nozzles under pressure. The nozzles may be mounted on a water-borne vehicle, e.g. a tug or lighter transversing the polluted region, or on an air- borne vehicle, e.g. hovercraft, helicopter or aircraft. The mean droplet size is about ten times that of the mean droplet size of a conventional nozzle and is pref. 1000 to 1500 microns. Because the droplets are larger, the spray is less susceptible to drift. The nozzles can be mounted higher from the water so as to cover a greater band width of polluted water.
