Internals for Steam Drums
Mechanical pre- and fine separators
Ensepatec provides enhanced liquid/gas separation equipment for the safe and economical removal of liquid droplets from saturated steam inside a steam drum.
The separation internals consist out of pre- and fine separation elements including axial and radial cyclones, flow distributors, vane type separators with coalescer pads for the removal of very fine droplets.
Ensepatec designs and selects a suitable combination of separation elements depending on the design parameters including internal drum diameter, the specified liquid levels and the allowable pressure loss. Upon request, Ensepatec conducts computational fluid-dynamics to verify steam flow distribution patterns.
Ensepatec offers the following internals for steam drums (for HRSG and auxiliary boilers):
- Cyclonic pre-separators
- Vane type separators
- Coalescing pads
- Flow pattern equalizers

Ensepatec offers 2 levels of guaranteed steam quality (downstream of the separator):
Level A
The steam quality is > 99.9%
Level B
The steam quality is > 99.99%

The materials of construction include stainless steel basic alloys 304, 304L, 316, 316L but also includes other alloys such as duplex steels and special nickel based alloys for very corrosive environments, and by request carbon steel.
