Steam Ejector Atomizing Desuperheater

Principle of Operation of Steam Ejector Atomizing Desuperheaters

Fig. 6970 and Fig. 6972 Steam Ejector Atomizing Desuperheaters serve a wide range of applications.

Fig. 6970 Steam Ejector Atomizing Desuperheaters are recommended for use where sufficient high-pressure steam is available to provide the atomizing steam supply. The most frequent application would be in combination reducing-desuperheating stations where flow rates vary widely. Steam Ejector Atomizing Desuperheaters utilize steam at higher than line pressure to atomize water. In the Fig. 6970 Steam Ejector Atomizing Desuperheater, the ejector action is used to entrain condensate from the pipeline.  

The Fig. 6972 Steam Ejector Atomizing Desuperheater is a Fig. 6970 Steam Ejector Atomizing Desuperheater without the recycle arrangement.

Low initial cost. Turndown ratios as high as 50 to 1 and greater can be achieved with the Fig. 6970 Steam Ejector Atomizing Desuperheaters only. There are no moving parts, a thermal sleeve is not required and no special pipe support is needed.

  • Control steam temperature to dryer drums in paper manufacturing.
  • Reduce temperature of high pressure steam reduced to a usable pressure.
  • Control temperature to evaporators.
