Download Case Study

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
