  2. Schroedahl Type DKV Desuperheater to Control the Temperature of Superheated Steam or Gas

    Product Features

    • The spray water cooler (lance design) works with controlled nozzle technology for extremely effective steam cooling
    • Spray head with integrated high-performance nozzles.
    • Selectable control characteristics for precise temperature control
    • A large water vapour pressure difference Delta p is permitted
    • Excellent pressure atomization
    • Tight shut-off, no leakage in closed position
    • High control accuracy over the entire control range
    • Tightly closing metallic seat. No leakage in closed position and thus no emptying of the cooling water lines possible.
    • Contains the pressure injection nozzle, no additional control valves required
    • High operational reliability through the use of simple components, minimal wear and tear
    • Excellent control accuracy over the entire control range

    Applications

    • For steam cooling in power plant applications and for general gas cooling applications with
      water injection

  3. Schroedahl Type DKT Steam-Atomizing Desuperheater

    Product Features

    • Suitable for difficult operating conditions, high quality temperature control and avoidance of temperature shocks (valve and piping)
    • Allows cooling operation when all other systems typically fail
    • For optimum temperature control close to saturation with a control ratio of up to 100:1
    • Ultimate cooler for low-speed steam cooling applications, large bandwidth and small distance/separation to saturation
    • The additional cooling water and atomizing steam control valve must be considered in the planning

    Applications

    • For low speed, highly adjustable desuperheater applications and low saturation separation.

    Nominal diameter: DN 150-800 / NPS 6-32

    Pressure Class: PN 25-250 / Class 150-1500
