Direct Contact Desuperheaters
Description Spirax Sarco direct contact desuperheaters reduce the temperature of superheated steam to produce steam temperatures approaching saturation temperature. To cool the superheated steam, water is entrained and flashed into vapour by absorbing heat from the steam. Typical applications: - To reduce the temperature of steam discharged from turbine by-pass systems on power plants for heat exchangers, dump stations etc. - To improve heat transfer of indirect contact heat exchangers - shell and tube , plate type, reactor heating jackets etc.
- To reduce the temperature of steam on direct contact applications - food cooking kettles, in-line steam heaters, tobacco drying plant and paper mills. Send us your requirements using our Desuperheater Enquiry Form available from our website.
