Easy control of steam temperature.
Desuperheaters are used in different applications for reducing the temperature of superheated steam down to saturation temperature or other desired level. With steam that is close to the saturation, it is possible to recover a large part of the energy used in for evaporation. Efficient and accurate cooling is therefore important to obtain high efficiency in heat transfer processes, but also to protect downstream equipment from high temperatures.
Desuperheater are available for installation in pipes from DN 25 to DN 1500 (NPS 1 to NPS 60) and can maintain temperatures down to 6 °C above saturation.
Askalon designs the most effective solution with the control valve as well as the desuperheater to meet the demands of the customers application.
Injection style nozzle
A Desuperheater with mechanical atomization and variable-geometry for use in applications with moderate load variations. Available with 1-4 nozzles. Installation through flanged connection to pipe sizes DN 200 - DN 1500 (NPS 8 - NPS 60). Maximum Cv 15.
Ring Style Desuperheater
Desuperheater intended for applications with low velocities. It is designed as a venturi tube with a nozzle placed near the Vena Contracta where the steam velocity is the highest and the static pressure is the lowest. This ensures efficient mixing and atomization even in low velocities.
Steam atomizing nozzle
A desuperheater that solves the problem with insufficient atomization of spraywater due to low steam velocity. Uses high-pressure steam for rapid and complete atomization of spraywater which ensures efficient desuperheating.
