Desuperheater

Function

High-temperature desuperheaters are used for temperature control in boiler superheaters (HP) and reheaters.

In addition, desuperheaters are utilized to regulate steam temperature, provide process steam, and protect downstream temperature-sensitive components.

Design

Forged body with flanged connections or butt-weld ends.
Actuator type freely selectable – hydraulic, pneumatic, or electric.

Benefits

The controllable desuperheaters form an integrated unit consisting of a cooling water control valve and a nozzle head.

Fine cooling water atomization even in the partial load range.
Precise setting of the specified temperature through accurate dosing of the injection volume.
High turndown ratio of 1:25 achieved by sealing inactive nozzles with piston rings.
Pre-throttling in 1 to max. 3 control stages, ensuring low-wear performance even with large pressure drops.
Drip-tight in the closed position
Equipped as standard with an upstream strainer.
All internal parts are replaceable without the need for mechanical machining.
Nozzle position / flange arrangement can be customized individually.
