Appropriate and effective syphon selection

If there were only one kind of rotating cylinder and only one set of operating conditions, choosing the right syphon system would be a simple matter. But that’s not the case. In order to end up with the most effective syphon system, a great deal of care must be taken to ensure an efficient and reliable syphon system is selected. Operating conditions such as machine speed, steam pressure, condensing loads, blow-through steam, and other parameters all have an effect on syphon selection.

Stationary Syphons

Stationary syphons are fixed in place and do not rotate with the cylinder. Because stationary syphons do not rotate, they are not subject to centrifugal forces and operating differential pressure requirements do not increase with rotational speed. Stationary syphons are available for slow, medium, and high speed applications.

Rotary Syphons

Rotary syphons are fixed to the inside of the cylinder and rotate with the cylinder. Because the rotary syphon moves with the rotating cylinder, it can be placed closer to the cylinder shell thereby reducing the level of condensate inside the cylinder. Rotating syphons are available for slow, medium, and high speed applications.
