Abstract
A desuperheater includes a ring body defining an axial flow path and one or more spray nozzle assemblies around the ring body. Each spray nozzle assembly is connected to a separate water manifold and steam manifold to provide cooling water and atomizing steam through the spray nozzle assemblies. A nozzle sleeve of each spray nozzle assembly has a solid, unitary body having first, second, and third fluid passages formed through the body. The first fluid passage is in fluid communication with the water manifold and with a first exit aperture formed in a second end of the body. The second fluid passage is in fluid communication with the steam manifold and with a second exit aperture formed in the second end of the body. The third fluid passage is in fluid communication with the steam manifold and with a third exit aperture formed in the second end of the body. The second and third exit apertures are positioned on opposite sides of the first exit aperture.
