Conventional power plants
The Stork Spray-type deaerator has been developed for application in conventional power plants.
Co-generation power plants
Based on the principles of deaerators for conventional power plants we developed special Stork Spray-type deaerators for/and connections to Heat Recovery Steam Generators (HRSG) installations.
The Stork Spray-type deaerator provides a high degree of flexibility with regards to the place in the cold end of a HRSG. Application of a Stork Spray-type deaerator gives the system designer several options for the connection to the system and to select the most suitable deaerating medium, or media.
The Stork Spray-type deaerator is especially suitable for this kind of application compared to tray-type deaerators. This because of its ability to operate with steam/water mixtures, its greater flexibility with respect to fast load changes, sliding pressure operation and wider operating ranges.
Depending on the client preferences and/or over-all efficiency considerations, the Stork Spray type deaerator can be installed in various ways in the boiler system. The principal difference between the various possibilities is set by the choice of deaerating medium, such as:
- (LP)-steam
- Pressurized hot-water
- Steam-water mixtures
