Single-variable Nozzle Steam Desuperheater / SNSD series
The bFS steam desuperheater SNSD consists of a tube shaped body with flange for bolting of the desuperheater to the insertion stud that is welded to the steam pipe. The water inlet is also flanged, at 90deg. angle to the desuperheater, to equipment service access.
The cooling water enters the inner nozzle chamber in the desuperheater through the flange. In the inner nozzle chamber the water is induced to fast rotation around the control plug by the special arrangement of the admission holes. The angle of the nozzle seat is slightly different from the nozzle holder so that the water velocity will accelerate the whole time and reach its maximum as it leaves the nozzle.
In order to maintain a constant pressure inside the injection nozzle, the latter is preloaded by a spring calibrated in function of the water/steam differential pressure.
Used for desuperheating of steam in small and medium sized pipes and is specially useful when the cooling water temperature is close to saturation.
