Steam-water mixers

Steam and water are two physical conditions of water: vaporous and liquid. If these media come into contact with each other in an uncontrolled manner, steam hammer can result, which can even lead to destruction of the plant involved. However some processes require the direct converging of steam and water, as shown here in a technical example.

Direct mixing of steam and water

The steam-water mixer baelz 585, another special type of ejector, is used in processes where water is to be heated rapidly by direct mixing of steam and water with maximum circulation.

Advantages at a glance
  • Optimal use of motive steam energy for the addition of the water to be heated
  • Optimal mixing of steam and water
  • Quiet operation thanks to a steam chamber especially designed for this purpose
  • Integration into process control with perfect interaction of the drive, the temperature sensor and the controller
  • Low investment costs
  • Can be used for all liquids permitted by this design
