Steam Water Cyclone Separator

High velocity centrifugal force and directional changes are key factors that enable such a high degree of separation.

Steam water cyclone separator. The built in cyclone separator removes condensate from the flow of steam with a high separation efficiency of 98. It has been very successful with a separation efficiency claimed to be as high as 99 97. This cfd analysis shows the fluid dynamics of a water steam cyclone separation unit. The webre steam water separator design is widely used in new zealand philippines indonesia kenya and elsewhere in the world.

The cyclonic or centrifugal type separator uses a series of fins to generate high speed cyclonic flow. In early designs the steam was discharged at the top of the vessel while the brine was discharged from the bottom of the vessel. While this seems adequate 0 03 brine carry over equates to about 0 24 tph for a 100mw plant. A widened tangential inlet extends the axial length of the conical portion of the separator increasing the width of the inlet while causing no derogation in steaming capacity and substantially lowering pressure drop.

Conical cyclone horizontal cyclone vertical cyclone separators are some of the technologies used. The steam water separator is a vital component in liquid dominated geothermal steam field equipment. The velocity of the steam causes it to swirl around the body of the separator throwing the heavier suspended water to the wall where it drains down to a steam trap installed under the unit. This yields improved productivity and product quality due to the resulting elimination of water hammer and the improved dryness of the steam.

The cyclone separator has undergone several improvements to maximise its efficiency. Volumetric flow is 230 m3 hr inlet velocity 3 m s. Built in free float trap. Most current designs are based on bangma s experience in wairakei in 1961 and lazalde crabtree s 1984 empirical approach.

While various designs exist the vertical cyclone separator dominates the design used worldwide. Steam leaving the primary separators typically still contains too much liquid in the form of droplets containing contaminants. Steam with 10 wate. Our cyclone steam separators have no internal moving parts or serviceable components it is simply a fully welded pressure vessel.
