US 2019/0376685 A1 · DESUPERHEATER AND SPRAY NOZZLES THEREFOR

Abstract

A spray nozzle assembly has a housing with a body and cap flange secure to the body to define a bore within the housing. A first aperture is formed through the body and intersects the bore and a second aperture is formed through the cap flange and intersects the bore. A nozzle sleeve is disposed within the bore and has a solid, unitary sleeve body. First and second fluid passages are formed through the sleeve body. The first fluid passage is in fluid communication with the first aperture and a first exit aperture in an end of the sleeve body. The second fluid passage is in fluid communication with the second aperture and second and third exit apertures in the end of the sleeve body, which are positioned on opposite sides of the first exit aperture. A portion of the second fluid passage surrounds the first fluid passage.
