a heat exchanger used to lower the temperature of superheated steam in a boiler unit or before a turbine. Changes in a boiler unit’s operation may lead to wide variations in the temperature of the superheated steam; a desuperheater then becomes necessary to prevent excessive superheating of the steam superheater or to maintain the steam turbine’s normal working conditions.
In the water tube boiler the upper drum (Boiler steam drum) provides for separation of steam from water. It also provides liquid holdup capacity (typically 10 to 60 seconds) to allow for a dynamic response to load changes without losing liquid in the downcomer and riser tubes.
