Features

  • Nozzles can be maintained or replaced without having to replace the entire unit.
  • The DSA desuperheater is capable of 40:1 rangeability.
  • DSA desuperheater can be located wherever is convenient in the pipeline.
  • In the DSA desuperheater, high-pressure steam is mixed with the spraywater to produce a critical or near-critical pressure drop in the atomizing steam for a very high velocity. The high velocity disperses the spraywater into very small particles
