Construction:

The Stork spray type deaerator is a single vessel design. This means that the deaerator and feedwater tank are combined in one vessel. This makes the deaeration process via the patented sprayer more effective. The condensate or demin water will be instantly heated up by the sprayer this making trays unnecessary.
The internals of the Stork spray type deaerator primarily consist of:

  • Stork patented sprayer
  • Steam charging device
  • Splash plates mounted around the sprayer
  • Circulation partitions (baffle plates)

Stork deaerators are designed according to a wide variety of standards and/or guidelines such as:

Code

ASME (with/without U-stamp)
EN13445
Any country specific requirements

Guideline

PED
VGB
HEI
