An improved spray nozzle assembly for use in a steam desuperheating device that is adapted to spray cooling water into a flow of superheated steam. The nozzle assembly is of simple construction with relatively few components and thus requires a minimal amount of maintenance. In addition the nozzle assembly is specifically configured to among other things prevent thermal shock to prescribed internal structural components thereof to prevent 'sticking' of a valve element thereof and to create a substantially uniformly distributed spray of cooling water for spraying into a flow of superheated steam in order to reduce the temperature of the steam. |
