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.

A fluid pressure reduction device is provided. The fluid pressure reduction device includes a body and a diffuser. The body defines an inlet, an outlet, and a fluid passageway extending between the inlet and the outlet. The body is made of a first material having a first hardness. A seating area is defined within the body. The diffuser is removably coupled to the seating area and disposed within the fluid passageway of the body. The diffuser defines at least one flowpath for reducing a pressure of a fluid flowing through the fluid passageway. The diffuser includes a second material having a second hardness greater than the first hardness of the first material.
