Claim Text:
1. A multi-spindle spray nozzle assembly for a desuperheating device configured for spraying cooling water into a steam pipe, the nozzle assembly comprising: a nozzle holder defining an internal fluid chamber and a holder axis; and at least two nozzles attached to the nozzle holder and fluidly communicating with the fluid chamber thereof, each of the nozzles defining a nozzle axis, each nozzle including a valve stem extending within the internal fluid chamber along a respective nozzle axis, each valve stem penetrating at least one plane on which the holder axis resides such that in at least one cross sectional plane, the valve stems are non-parallel to the holder axis and overlap with each other and the holder axis; the nozzle holder being sized and configured such the nozzle axes of the nozzles attached thereto extend at prescribed, non-parallel orientations relative to the holder axis and each other, and further do not intersect each other; the at least two nozzles being sized and configured to produce at least two independent generally conical spray cones of cooling water when cooling water flows through the at least two nozzles.
