Desuperheater

The multiple design VariBull is equipped with several DM wall-mounted nozzles connected among themselves and welded to an injection chamber BW inserted into the steam pipe.

The nozzles of MDM design may have different size and settings, for top performances of desuperheating at various flowrates, and to improve turndown as well.

Desuperheater

The variable area spring assisted desuperheater with DM nozzles minimizes the limitation of fixed area types deriving from the fluid velocity reduction when flowrate decreases. This is obtained
by automatically reducing the passage area when flowrate decreases to maintain a fluid velocity consistent with the need of a good atomization.
