Abstract: A cluster head nozzle for spraying a fluid, having a single-piece housing and multiple outlet openings which are arranged around a central region on a front side of the housing for individual spray jets, and at least one purge air outlet opening for purge air. The at least one purge air outlet opening and sections of a feed channel for the purge air are provided in the single-piece housing.

Abstract: A nozzle for spraying liquids, in particular a dual-substance nozzle, having a nozzle housing and a plurality of outlet openings in the nozzle housing, wherein each outlet opening is arranged at the end of an outlet passage through the wall of the nozzle housing, and wherein the plurality of outlet openings is arranged in a circle on the nozzle housing. An outlet angle which the respective central axis of the outlet passage associated with the outlet opening encloses with a central longitudinal axis of the nozzle housing differs between at least one first and at least one second outlet opening.

Abstract: The invention relates to a spray arrangement having at least one return flow nozzle for injecting liquid into a process environment, having a storage tank for the liquid to be injected, at least one return flow nozzle, at least one feed line from the storage tank to the at least one return flow nozzle, at least one pump in the feed line, at least one return line from the return flow nozzle to the storage tank and at least one regulating valve for regulating a liquid quantity injected by the at least one return flow nozzle, wherein at least one further nozzle is provided, which is connected to the feed line by means of a controllable valve for enabling and shutting off a liquid feed.

Abstract: A method for producing a spray jet from a liquid/gas mixture with a two-component nozzle having a nozzle housing, including the steps of blending a supplied liquid and a supplied gas and producing a spray jet consisting of gas and liquid drops, producing a gas jet and mixing of gas jet with the spray jet.
