Abstract

Spray heads for use with desuperheaters and desuperheaters including such spray heads. One example of a spray head includes a main body having an exterior surface and defining a central passage, the main body adapted for connection to a source of fluid, at least one entrance port formed in the main body along the central passage, and at least one spray nozzle arranged adjacent the exterior surface of the main body. The spray head also includes a plurality of flow passages, each of the plurality of flow passages providing fluid communication between the entrance port and an exit opening of the spray nozzle. A first one of the plurality of flow passages follows a first non-linear path and has a first distance, and a second one of the plurality of flow passages follows a second non-linear path and has a second distance different from the first distance.
