Blowdown Separators

Wilson boiler blowdown systems are built around the Wilson centrifugal blowdown separator. The boiler blowoff is piped tangentially into the separator. In the resulting vortex the pressure is released, allowing the steam flash to rise through the vent while the water and sludge fall through the drain. A stainless steel wear plate protects against erosion in the blowoff entry area. No water is retained in the separator.

Blowdown Separators Illustration & Dimensions

Vents sized for maximum of 5 psig in separator. The drains sized for flow of blowdown effluent plus aftercooler water for maximum temperature 140F to sewer. For sizing details refer to Wilson separator selection charts A&B. Note: Custom sizes are available. Consult the factory for more information.

1) Vessel connections may be threaded, flanged, or welded or any combination required by your application. Consult factory.
2) Material thickness must comply with state and local regulations. All separators shown are constructed to A.S.M.E. Code.
3) Separator design pressures are suitable with boiler maximum allowable working pressures to four times the separator design pressure (Per National Board recommendations). Ex:A separator with a 150 psig design pressure may be used with a 600psig
maximum allowable working pressure boiler.
4) Separators may be registered with the National Board (optional).
