Abstract
A spray system for spraying a secondary fluid into a primary fluid. The secondary fluid is gaseous, liquid or contains fine particulate solids to be dispersed in the primary fluid. The spray system has a central nozzle for the primary fluid and a nozzle for the secondary fluid. The nozzle housing has a tubular design and the central nozzle is provided with a central passage for the primary fluid. The passage, as seen in the flow direction, has convergent inlet region, a constriction and a divergent outlet part. An outlet opening for the secondary fluid is arranged on the downstream end of the nozzle housing and an outlet opening generates a spray jet of secondary fluid that surrounds the primary fluid exiting the central passage in a substantially ring-shaped manner.
