Abstract
In accordance with the present invention, there is provided a multi-spindle spray nozzle assembly for a steam desuperheating or attemperator device. The nozzle assembly features a nozzle holder which accommodates two small, spring-loaded nozzles, each of which is adapted to produce a spray pattern of reduced cone angle (e.g., approximately 60°) in comparison to currently know nozzle designs. The two nozzles are positioned within the nozzle holder such that they diverge from the axis thereof as allows the spray pattern generated thereby to be effectively tilted into the flow of steam within a desuperheating device having the nozzle assembly interfaced thereto.
Claims20
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.

- 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 and including opposed first and second ends spaced apart along the respective nozzle axis, the holder axis residing on at least one plane which each valve stem penetrates such that the opposed first and second ends of each valve stem are located on opposed sides of the at least one plane;
- 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.
